      Abstract: Energy & Environment, Ahead of Print.
      Water hyacinth is an invasive alien plant with several impacts on the environment, economy and society. The plant’s high degree of proliferation makes its mitigation difficult and sometimes complex. However, existing evidence suggests that water hyacinth is a sustainable substrate for biogas production. Using the pretreatment processes for the optimisation conditions for biogas production from water hyacinth, this study analysed the effects of moisture content (60%, 70% and 75%) on Trichoderma atroviride pretreatment of water hyacinth and the impact of the pretreatment on biogas production. Anaerobic digestion of the water hyacinth process was performed at 35°C for 35 days. The modified Gompertz model was used to analyse and predict the appropriate kinetic variables of the digestion process. Biogas yields from untreated, pretreated-60%, pretreated-70% and pretreated-75% were optimal at 135, 210, 217 and 223.4 mL/g of volatile solids (VS). These results suggest the pretreatment of water hyacinth enhanced the degradability of water hyacinth by breaking down the cell wall structure and facilitating its use by microorganisms. Furthermore, the results also confirmed that the higher the moisture content, the easier the biodegradation rate and, consequently, the higher the biogas yield. The model predicted maximum methane production potential ranging from 91.84 to 201 mL/g VS, and the maximum methane yield rate was within 10.12–15.12 mL/day. The lag phase varied between 2.46 and 6.94 days. The percentage error between experimental and model outcomes for untreated, pretreated-60%, pretreated-70% and pretreated-75% are 17.96%, 16.67%, 14.20% and 4.68%, respectively, while the coefficients of determination of the model varied between 0.905 and 0.975, demonstrating significant reliability on attained factors.

  • Asymmetric impacts of natural gas consumption on renewable energy and
           economic growth in Kingdom of Saudi Arabia and the United Arab Emirates

      Authors: Md Shabbir Alam, Tomiwa Sunday Adebayo, Radwa Radwan Said, Naushad Alam, Cosimo Magazzino, Uzma Khan
      Abstract: Energy & Environment, Ahead of Print.
      The globe is now in ecological turmoil as a result of the unrelenting increase in global warming. As a result, governments worldwide are committing to decarbonizing the environment, with the United Arab Emirates (UAE) and the Kingdom of Saudi Arabia (KSA) playing an important role in this effort. Hence, this paper evaluates the nonlinear (asymmetric) impact of natural gas consumption on renewable energy consumption and economic growth in the KSA and the UAE utilizing data stretching from 1990 to 2020. The study also considers other drivers of renewable energy consumption and economic growth, such as trade openness and CO2 emissions. The study utilizes nonlinear autoregressive distributed lag (ARDL) to evaluate these associations. The outcomes of bounds nonlinear ARDL (NARDL), affirm the long-run association between the variables in both countries. The nonlinear results show that positive and negative shocks in natural gas consumption have a negative impact on renewable energy in both UAE and KSA. In contrast, positive and negative shocks in natural gas consumption impact economic growth positively. The study proposed vital policy recommendations based on these results.

  • How to promote China's green economic development' The combination
           effects of consumption tax and carbon tax policies

    • Free pre-print version: Loading...

      Authors: Weijiang Liu, Min Liu, Yangyang Li, Tingting Liu
      Abstract: Energy & Environment, Ahead of Print.
      With massive greenhouse gas emissions causing global warming, emissions reduction and economic growth are essential objectives that must be balanced in sustainable development worldwide. The tax policy is an effective tool for environmental protection and economic regulation. Over the years, China has continuously adjusted tax policies, and the tax structure has tended to be optimized, but there is still no carbon tax. In this regard, based on the purpose of promoting the harmonious development of the environment and economy, this article builds a dynamic computable general equilibrium (CGE) model with five scenarios to assess the economic, energy, and environmental effects of the consumption tax, the carbon tax as well as their combination in China during 2022 to 2035. The results show that lowering the consumption tax on non-energy-intensive commodities boosts long-term economic growth but is not conducive to emissions reduction. Additionally, a separate carbon tax promotes a cleaner energy transition, reducing emissions while harming the economy. In contrast to the stand-alone policy treatment, the combination of lower consumption taxes on non-energy-intensive commodities with the medium carbon tax rate could have a “double dividend” effect, with long-term economic growth and consistently reduced pollution emissions. In the future, it will be essential to implement the appropriate policy combination to reduce fossil energy consumption and increase clean energy share. Thus, it would help to achieve China's 2030 peak carbon target and promote green economic development effectively.

  • Revisiting Hofstede's dimensions of national culture and environmental
           sustainability

    • Free pre-print version: Loading...

      Authors: Chi-Jui Huang, Heng-Yih Liu, Ting-Ling Lin, Jia-Yu Lai
      Abstract: Energy & Environment, Ahead of Print.
      This study investigates the impact of Hofstede's dimensions of national culture on environmental sustainability across 57 countries. Hofstede's national culture construct reflects and gauges the extent of the inclination of a particular national person toward either economic development or environmental preservation. Climate change and pollution have continuously devastated the environment in recent decades. The United Nations Sustainable Development Goals aim to achieve a more sustainable future and prevent further environmental destruction. This study aims to explore whether national culture significantly influences national environmental sustainability. We use national environmental performance as the proxy for national environmental sustainability and adopt the ordinary least squares regression model to explore the possible relationship with two datasets of international indices; one is proposed by Hofstede, and the other is proposed by Germanwatch. Our results show that the power distance index has a strong negative impact on the climate change performance index (CCPI), greenhouse gas (GHG) emissions, renewable energy, and energy use. Further, the masculinity index is negatively related to CCPI and GHG emissions. The individual index is also negatively related to renewable energy. Furthermore, indulgence is positively associated with climate policy. These findings support the notion that nations should consider their cultural characteristics to improve environmental sustainability. Thus, conducting a national environmental policy that aligns with national culture is suggested to achieve environmental sustainability.

      Authors: Haichao Yang, Sheng Zhang
      Abstract: Energy & Environment, Ahead of Print.
      In the wave of global e-waste migration, the problem of e-waste management in developing countries and underdeveloped areas has become the focus of academic attention. In the developing countries represented by China, there are still a large number of electronic waste flowing into the extensive manual dismantling workshops. These informal recycling and disposal have a huge adverse impact on the environment of the surrounding areas, and there are huge health and ecological risks. How to effectively deal with the risks generated in the process of e-waste disposal is of great significance to global e-waste management. At present, risk assessment and management have not been included in China's existing e-waste management system. This article analyzes the health, ecological, and regional risks of e-waste in the four links of recycling, dismantling, resource utilization, and final disposal. At the same time, a list of e-waste risk assessment processes is formulated, and a risk management framework for e-waste in China is proposed. It enriches the theoretical and empirical research on e-waste management and provides Chinese practices for the future construction of an industrial 4.0 sustainable ecosystem.

  • Analyzing the risk spillovers of international crude oil on China's corn
           and biofuel ethanol markets: A transition toward green economy and
           environmental sustainability

    • Free pre-print version: Loading...

      Authors: Jin Zhang, Zhenqing Lin, Jinkai Li
      Abstract: Energy & Environment, Ahead of Print.
      This study aims to analyze the risk spillover effects between the global crude oil market and the biofuel ethanol and corn markets in China, employing a DCC-GARCH-Copula-CoVaR model and basing the weekly price data from 2012 to 2021. The empirical results revealed that there were dynamic conditional correlations among international crude oil, China's biofuel ethanol, and corn markets. Following the COVID-19 outbreak, the CoVaR and ΔCoVaR changed, which caused a sharp increase in the mean values and volatility. Additionally, China's biofuel ethanol market is more vulnerable to the risk spillovers from the international crude oil market than China's corn market. However, China's markets do not appear to have obvious risk spillover effects on the global market. The implications of the results are discussed in financial market supervision, including the risk management and portfolio adjustment.

  • What determines household cooking fuel preferences' Empirical evidence
           from South Korea

    • Free pre-print version: Loading...

      Authors: Chan Hee Lee, Jong Ho Hong, Sung Hoon Kang
      Abstract: Energy & Environment, Ahead of Print.
      This study examines the determinants of modern cooking fuel choices in Korea. The ordered probit model is estimated using an extensive online survey of Korean household energy consumers. Our empirical results showed that age, gender, and education are significant determinants of modern cooking fuel choices among the socioeconomic demographic variables: females, older people, and highly educated people are more likely to prefer electricity. Also, electricity is more likely to be preferred over natural gas by people who have a higher preference for district heating. Two psychological factors significantly influence cooking fuel choices. People whose behaviors are environment-friendly and people who are more health-conscious are more likely to prefer electricity over natural gas or propane. There are three important insights into the cooking fuel transition toward electricity. First, as interest in health and climate change has significantly increased in recent years in Korea, it may stimulate the transition from natural gas or propane to electricity. Second, electrification of cooking methods will be beneficial for the environment if electricity generation becomes less carbon-intensive. Since electricity in Korea is mainly generated by fossil fuels, it is crucial to implement more aggressive policies toward renewable sources in the energy mix for electricity generation. Third, the public should better understand why this problem cannot be overlooked because the energy mix is important in mitigating climate change. The better the people understand the exact relationship between energy consumption and pollutant emissions, the more effective and environmentally sound will the energy mix policy become.

      Authors: Tasir Khan, Ishfaq Ahmad, Yejuan Wang, Muhammad Salam, Amina Shahzadi, Masooma Batool
      Abstract: Energy & Environment, Ahead of Print.
      The distribution models of wind speed data are essential to assess the potential wind speed energy because they decrease the uncertainty in estimating wind energy output. Therefore, before performing a detailed potential energy analysis, the precise distribution model for data relating to wind speed must be found. This research contains material from numerous goodness-of-fit tests, such as Kolmogorov–Simonov, Anderson–Darling, chi-square, root mean square error, Akaike information criterion, and Bayesian information criterion, which were combined finally to determine the wind speed of the best-fitted distribution. The suggested method collectively makes each criterion. This method was useful in statistically fitting 14 distribution models to wind speed data collected at four sites in Pakistan. The consequences show that this method provides the best source for selecting the most suitable wind speed statistical distribution. Also, the graphical representation is consistent with the analytical consequences. This research presents three estimation methods that can be used to calculate the different distributions used to estimate the wind. In the suggested maximum likelihood method, method of moments, and maximum likelihood estimation, the third-order moment used in the wind energy formula is a crucial function because it contributes to the precise estimate of wind energy. In order to prove the presence of the suggested method of moments, it was compared with well-known estimation methods, such as the method of linear moments and maximum likelihood estimation. In the relative analysis, given several goodness-of-fit tests, the presentation of the considered techniques is estimated based on the actual wind speed evaluated in different periods. The results show that the method of moments provides a more precise estimation than other commonly used methods for estimating wind energy based on the 14 distributions. Therefore, the method of moments can be a better technique for assessing wind energy.

      Authors: Haitao Wu, Mengzhe Sun, Wenjia Zhang, Yunxia Guo, Muhammad Irfan, Mingyue Lu, Yu Hao
      Abstract: Energy & Environment, Ahead of Print.
      In China, urbanization is mainly stimulated by resource flows, and industrialization is normally accompanied by an increase in the proportion of the urban population and urban land area. During the process, urbanization at a rapid pace often induces a huge consumption of energy and environmental emissions. Nevertheless, it is also worth considering whether urbanization positively affects urban environment promotion. With a more solid economic foundation, urban subjects will carry out energy conservation and emission reduction (ECER) from various aspects, primarily focusing on technological innovation, advancement of production mechanisms and structural optimization. Along these lines, this study aims to examine urbanization's direct and indirect impact on energy conservation and emission reduction using panel data consisting of 196 Chinese cities for the period of 2011–2018 with a Slacks-based model and transmission mechanism. Study results indicate that urbanization's development can give a direct impetus to ECER, which is quite robust after employing a series of robust tests, including instrumental variable estimation. Besides, urbanization indirectly influences ECER by promoting economic growth, better allocation of resources, internet advancement, and adjusting the employment structure. Further investigation suggests that the relationship between urbanization and ECER is nonlinear, depending on the levels of the above-mentioned mediating variables. Finally, essential policy suggestions are proposed, i.e. promoting high-quality development of urban clusters, accelerating the policies for ECER, and paying more attention to economic growth, resource allocation, internet technology, and employment structure.

      Abstract: Energy & Environment, Ahead of Print.
      This study examines the Indian inclusive sustainable development. India ranked third in global carbon emissions amidst its economic performance. This tells more about one-sided sustainable development policy of the country. With this trend of development anchored only on Indian economic activities, we consider it important to research the economy with instruments (such as technological innovation, foreign direct investment (FDI), and agriculture) that are unique to the country. India's data from 1980 to 2019 are applied to this study with two models for testing both economic and environmental developments. We utilized two scientific methods (non-linear autoregressive distributive lag (NARDL) and dynamic ordinary least squares (DOLS)) to demonstrate both symmetric and asymmetric technical analyses. Findings from NARDL show that technological innovation and FDI are mitigating carbon emissions, while economic growth and agriculture are increasing carbon emissions thereby impacting negatively the environment. Also, the result from the economic model confirms that all variables are impacting favorably on economic development except carbon emission. The findings from DOLS support the findings from NARDL. The result confirmed that India is yet to attain inclusive sustainable development, however, it is evident that with the right policy framed on tech innovation and FDI, the country could attain balanced sustainable development. Having seen, the dual capacity of both technological innovation and FDI toward strengthening both the economy and environment, it is worthy to consider these instruments as among the sustainable policies

      Abstract: Energy & Environment, Ahead of Print.
      Reducing greenhouse gas (GHG) emissions induced environmental hazards is one of the most important goals of future research the energy economy and the environment. This challenge is becoming more important in developing countries, including Iran, with high energy intensity and is one of the leading countries in GHG emissions. This study aims to visualize emissions from electricity generation in Khuzestan province, southern Iran. Khuzestan is the largest producer of electricity and the country's energy capital. Khuzestan's electricity supply and demand system was simulated and examined under green scenarios till 2050 by assessing the existing situation and choosing a suitable low-carbon energy system for the future. One of the results of this research is to reduce emissions in terms of energy management strategies in the short term and the ineffectiveness of development strategies regardless of consumption management strategies. Electricity supply optimization scenarios are attractive in the long term, which indicates the costly implementation of development strategies. Combining solutions to balance the energy economy and environment is more effective. The OKEP scenario as a combination of consumption management and development strategies showed that it would maintain its positive impact in the short and long term and successfully reduce emissions. In this scenario, the net present value (NPV) attractiveness is over $ 6706 million and saves the emission of 179 MtCO2e. Compared to the business as usual (BAU) scenario, more than 90 Bm3NGe savings and a 3.62% increase in renewables share are other benefits of this scenario.

      Abstract: Energy & Environment, Ahead of Print.
      Environmental and socio-economic activities are vital to achieving sustainable growth. Corporate social responsibility (CSR) originated to achieve social equilibrium via the sustainable performance of organizations. Nevertheless, corporations require ample resources to cope with the concepts of CSR and sustainability. Accordingly, the present research analyses the function of green financing, which encompasses the economic, social, and environmental practices for accomplishing and developing CSR goals in the automobile industry. Using questionnaire survey and structural equation modelling, this study's data supports the contribution of green finance and its associated practices (economic (β = 0.248***, 0.239**, 0.312***, 0.125**, 0.549***), social (β = 0.343***, 0.147**, 0.458***, 0.593***, 0.257***), and environmental practices (β = 0.487***, 0.164**, 0.238**, 0.043*, 0.126**)) to the enhancement of CSR's implications. Research findings suggest that organizations should devote more monetary resources to enhancing CSR traits. Future research directions are also discussed at the end of study.

      Abstract: Energy & Environment, Ahead of Print.
      The renewable electricity quota standard (RES) policy plays an important role in achieving sustainable and green development targets. Thus, it is essential to measure the sustainability of the electric power sectors in the context of RES. In terms of the energy and environmental efficiency (EEE) measurements, few studies divided energy inputs into renewable and non-renewable energy or explored the restricted problem of minimizing resource summation. To fill these gaps, we propose an improved fix-sum energy input data envelopment analysis (FSIDEA) model based on the adjustment strategy of weighted sum minimization of renewable energy inputs. The assurance region (AR) restriction and renewable energy input sum constraint (IC) are, respectively, imposed on the FSIDEA model to achieve the common equilibrium effective frontier (EEF). Finally, this study assesses the EEE of the electric power sectors in China's 30 main regions based on the common EEF. The result reveals that Beijing and Shanghai can be selected as benchmarks after efficiency comparison. In addition, our proposed model can compressively rank all decision-making units (DMUs) compared with traditional efficiency models.

      Authors: Le Thanh Ha
      Abstract: Energy & Environment, Ahead of Print.
      This article is the first to study a nexus between financialization and circularity performance in the European region. To reflect the circularity performance, we use six different measures, including the amount of municipal waste, the number of circularity patents, the amount of circular material used, the rate of recycling waste, the rate of recycling biowaste, and the rate of recycling e-waste. By using various econometric techniques (namely a panel-corrected standard errors [PCSE] model, a feasible generalized least square estimates [FGLS] model, and the two-step General Method of Moment [the two-step GMM), our study indicates that financialization is an enabler for circularity. However, these results are only statistically significant for the financial institution's development, while the financial market has a positive yet insignificant impact on circularity performance. The development of the financial institution is reported to increase municipal waste and the amount of recycling biowaste and e-waste, thus promoting the path toward the circular economy. To shed light on the financialization-circularity nexus, we use the different dimensions of financialization dynamics and report heterogeneous influences on the different issues of circularity performance. Furthermore, the results from the dynamic fixed effects (DFE) in the autoregressive distributed lag (ARDL) method suggest that the impact of financial development only becomes apparent in the long term.

      Abstract: Energy & Environment, Ahead of Print.
      Complex dyes have an adverse impact on the environment since they have a high aqueous solubility and are very challenging to be removed using conventional approaches. A series of batch tests were performed to determine the optimum parameters for the direct blue 78 dye adsorption process as a function of chemically treated coal fly ash (TCFA) Effect of fly ash dose, contact time and dye initial concentration were studied using an industrial wastewater. A pilot plant, consisting of three stages; mixing, sedimentation and filtration was designed and implemented to investigate the ability of TCFA to remove COD, BOD5, TDS and TSS from textile wastewater under optimal conditions. A series of fly ash physico-chemical analysis including particles size analysis, zeta potential, XRD, EDX, BET, SEM and FTIR were investigated. The results showed that the particles size and zeta potential for raw coal fly ash were 1.2 µm and −20.70 mv. Chemical treatment process using hydrochloric acid resulted reducing the particles size of fly ash from 1.2 µm to 0.95 µm. Zeta potential value increased to + 7.20 mv. Batch adsorption process showed that the removal efficiency decreased as the primary dye concentration increased. It increased when fly ash loading and contact time increased. Dyes removal was achieved up to 99.7% using TCFA loading 3gL−1 for initial dye concentration10 mgL−1. Studies on equilibrium revealed that the equilibrium data was closely fitted to the Freundlich and Langmuir isotherm models. Kinetic study of adsorption process was studied in detial. Based on high correlation coefficient (R2 = 0.999), the results were followed pseudo second-order model.

      Authors: Md. Mominur Rahman, Md. Abdul Halim
      Abstract: Energy & Environment, Ahead of Print.
      The study aims to examine the effects of trade balance, economic growth, green field investment, energy use, financial development, and urbanization on environmental sustainability in BRICS countries. This study proceeds to estimate the long-term association using the fully modified ordinary least square (FMOLS) and the dynamic ordinary least square (DOLS) panel estimation methods for the years 1991–2020. This empirical study finds that the ratio of exports to imports has a negative effect on environmental degradation. This indicates that increasing the trade balance eventually leads to environmental sustainability, which finally improves living standards and environmental conditions in the BRICS countries. The findings further show that green field investment and financial development substantially improve environmental sustainability, but energy use, urbanization, and economic growth desperately negatively affect environmental sustainability. Additionally, this research finds a unidirectional relationship of environmental sustainability with trade balance, green field investment, energy use, urbanization, and economic growth rate. This study states how BRICS countries can be protected through trade balance controlling environmental degradation. Thus, this research provides improved orientations to the policymakers of BRICS countries to design policy in favor of the environment.

      Authors: Muhammad Zubair Chishti, Eyup Dogan
      Abstract: Energy & Environment, Ahead of Print.
      In line with the importance of SDG-7, a number of studies have endeavored to divulge the changes in renewable energy consumption (REC); however, the literature fails to either understand the importance of technology i.e., information communication technologies (ICT) and macroeconomic uncertainty in this context or employ robust econometric techniques. This research paper extends the prior literature by focusing on technology and macroeconomic uncertainty as novel determinants in addition to natural resources, human development, globalization, and economic growth as control variables of renewable energy for the top 10 renewable energy-consuming countries by applying several second and third generation econometric tests on annual data from 1990 to 2017. The empirical estimations determine ICT as a crucial factor of renewable energy, suggesting that it significantly triggers REC in the top economies. Conversely, the detrimental effects of uncertainty tend to shrink REC. Furthermore, natural resources, human development, globalization, and economic growth significantly boost REC as consistent with the existing literature. Based on these findings, this study suggests several SGD-oriented policies.

      Abstract: Energy & Environment, Ahead of Print.
      This paper is concerned with the impact on the global greenhouse effect issues and focus on comprehensive multi-indicator though analyze the relationship between CO2 emissions and real GDP, energy intensity, fraction of the renewable energy supply out of the total energy supply, and energy consumption from different sectors, including the agricultural, service, industrial and transport sectors. The panel data encompass all 37 Organization for Economic Co-operation and Development (OECD) member countries covering 20 years from 2000 to 2019 and divide into two subsamples, the first and second ten years, for comparison. The empirical results of all parameters track the sound progress of green growth trend in OECD countries in the second ten years (2010–2019). According to the OECD, green growth strategy had been acknowledged in OECD Ministerial Council Meeting in June 2009. Thus, the study divided into the first and second ten years with 2010 as the boundary to compare and the empirical result also indicates the green growth strategy in OECD countries have gradually matured in the last ten years. The implementation of the policy framework and measures includes pricing, removing perverse subsidies, ensuring the regulatory standards of energy efficiency, innovation, and infrastructure investments might also provide a reference and important information for energy policy makers.

      Authors: Weihua Yu, Xin Jin
      Abstract: Energy & Environment, Ahead of Print.
      As a result of high energy consumption and pollution from energy-intensive industries, the Chinese government has implemented a series of policies. A comprehensive assessment of these policies is necessary to guide the green transformation and upgrading of the industry, however, little research has been conducted on this issue. This article takes China's economic policy uncertainty (EPU) Index as a comprehensive and continuous policy shock and investigates the impact of EPU on the financial performance of energy-intensive firms. Based on 289 listed energy-intensive companies from 2003 to 2018, we find that EPU negatively affects the financial performance of firms, and the negative effect is robust after replacing the dependent variable and endogenous discussion. Further, the negative impacts are more pronounced for midwestern, non-SOE firms, as well as ferrous metal and chemical product manufacturers. Moreover, our results indicate that the negative impact of EPU on performance is mitigated for firms with high cash holdings and low debt ratios.

      Abstract: Energy & Environment, Ahead of Print.
      Several nations, including Mexico, are encountering problems with accomplishing the targets of sustainable development goals (SDGs). This study addresses how to develop SDG agenda for Mexico, which may also be applied to other emerging markets with comparable profiles. Therefore, this study utilizes a newly developed load capacity factor (LCF, a detailed environmental evaluation tool) that combines biocapacity (supply side) and ecological foot (demand side) to examine the effect of renewable energy consumption and trade openness on LCF while controlling for nonrenewable energy consumption and economic growth in the case of Mexico during 1970–2017. Using the dual adjustment approach, we find evidence of long-run cointegration nexus among the series. In addition, trade openness affects LCF positively, whereas renewable energy consumption, economic growth, and nonrenewable energy consumption impact LCF negatively. Furthermore, results of the frequency domain causality show that all the variables can predict LCF in the long-term. Based on these results, Mexico should focus on promoting public understanding of green energy and environmental preservation measures and participate in the production of nonenergy-consuming and ecologically friendly products while compelling polluting enterprises to migrate to countries with less stringent environmental restrictions.

      Authors: Iyabo Adeola Olanrele, José Alberto Fuinhas
      Abstract: Energy & Environment, Ahead of Print.
      Most sub-Saharan African electricity generation is through renewable energy sources. However, the pace of renewable expansion is slow, mirrored by the region's low per capita electric power consumption and electricity access. The study examines the determinants of renewable electricity generation adoption in sub-Saharan Africa (SSA) countries using content description and a panel ARDL analysis. Findings from this study show that hydroelectric power is the long-standing renewable electricity source in the region. The deployment of non-hydro renewable electricity sources is slow despite its vast potential. In most evaluated countries, renewable electricity targets are below actual realization. Also, policies are ineffective in driving renewable electricity adoption, as indicated by the negative relationship between renewable electricity generation and policy enactments in SSA. Foreign direct investment and financial development significantly negatively impact renewable electricity adoption, suggesting that both factors do not expand renewable electricity generation. Feasible strategies for increasing non-hydro renewable electricity use include activating renewable energy support mechanisms and their uptake. In addition, governments in SSA should strengthen their legal and institutional frameworks and encourage lessening bottlenecks and bureaucracies associated with renewable electricity investment.

      Abstract: Energy & Environment, Ahead of Print.
      Developing countries are facing many electricity crises such as low production, worst power outages, blackouts, and poor inadequate supplies. Most of their rural areas have no basic power infrastructure as it requires long transmission lines, which causes high installation, operation, maintenance costs and line losses issues. The people of these unconnected rural areas belong to low-income families and use kerosene oil, candles, small solar panels, and batteries to meet their basic electricity needs. As an alternative, renewable-based hybrid energy systems have enormous potential. It is also environmentally friendly and low-cost, sustainable, and promising solution to electrify rural off-grid areas. This research work focuses on the economic and optimal design of a renewable-based hybrid energy system for the rural off-grid area of Pakistan. HOMER (Hybrid Optimization of Multiple Energy Resources) software is used to perform techno-economic and environmental analysis. The optimization results show that the most economical and optimal configuration is PV/diesel generator with batteries having lower harmful emissions. Furthermore, the sensitivity analysis is performed to refine the results which show that the most optimal system will remain sustainable if variations occur in the sensitivity variables in the future. Moreover, the results and findings of this study can help the government to make effective policies and planning to provide reliable and affordable electricity to the off-grid areas, to improve the electrification rate in the country.

      Authors: Muhammad Irfan, Tomiwa Sunday Adebayo, Jinyang Cai, Hazar Dördüncü, Farrukh Shahzad
      Abstract: Energy & Environment, Ahead of Print.
      This research utilizes a bootstrap rolling-window (BRW) causality test to explore the causal interrelationship between nuclear energy consumption (NUC) and carbon dioxide emissions (CO2) in 6 developed countries from 1980 to 2020. When there are structural shifts in the full-sample time series, empirical research exploring causality between two-time series generates erroneous conclusions. On the other hand, the BRW method allows researchers to find potential time-varying causality between time series using sub-sample data. The outcomes of the BRW causality test disclosed the following results: (i) a unidirectional negative causality from NUC to CO2 without feedback was found for Japan; (ii) a negative causality at sup-sample periods from NUC to CO2 surfaced at the sub-sample period while a positive causality surfaced from NUC to CO2 in sub-sample period for the United States of America (USA) and France; (iii) a negative feedback causality between NUC and CO2 was found For Canada; (iv) a positive unidirectional causality surfaced from NUC to CO2 was found for Germany, which implies that consumption of NUC worsens the environment in the sub-sampled period. The results may have policy consequences for the selected developed countries regarding NUC and CO2 nexus.

      Abstract: Energy & Environment, Ahead of Print.
      Developing an inclusive policy agenda for ensuring sustainable development is a challenge for both developed and developing countries. The developing countries face challenges in designing policy that achieves sustainable development goals based on environmental awareness, and that is one of the main contributions of this research. By taking into account the SDG 13 (climate action) and 7 (clean and affordable energy) this study examines the influence of education, natural resource availability, financial development, urbanization, and economic growth for ASEAN nations from 1991 to 2018. For an empirical estimate, second-generation approaches are used. The findings demonstrate the energizing influence of renewable energy usage in altering the environmental quality. According to the empirical findings, renewable energy and education lower CO2 emissions by 0.46% and 0.22%, respectively. Financial development, urbanization, and natural resource depletion all have a 0.14%, 0.03%, and 0.08% impact on the environment, respectively. The heterogeneous causality analysis reveals the feedback effect, i.e., bidirectional causal links between education, carbon emissions, and the use of renewable energy. This empirical data implies that nations should enhance investment in renewable energy and education sectors, as well as prepare for renewable energy research and development, to ensure environmental sustainability. This research has policy implications for ASEAN countries in terms of renewable energy and education investments. Through this agenda, the objectives of SDG 13 and SDG 7 will be achieved, while SDG 4 will be targeted.

      Abstract: Energy & Environment, Ahead of Print.
      The increasing demand, rapid consumption, price increase, limited reserves, and environmental concern due to pollution produced by conventional fossil fuel (diesel & gasoline) are a few reasons why biofuels need to be explored. The present paper employs a systematic methodology to examine the performance of a 20% volumetric blend of Sal biodiesel (S20) blended with diesel using α-aluminium oxide (α-Al2O3) nanoparticles (NP) as additives and is compared with a diesel under like circumstances. The central composite design, Box-Behnken design (BBD) based response surface methodology, and desirability tests are used in the organized experiments on a diesel engine configuration to facilitate calibration. The created multivariate regression model yields all of the best engine inputs. Interaction effects are used to determine the most influential element by observing the interaction of two distinct input factors on a single response. According to the desirability tests, the highest estimated desirability was 0.579; the optimal input parameters found are 21°bTDC injection timing (IT), 238 bar injection pressure (IOP), 17 compression ratio (CR), and 74 ppm concentration of α-Al2O3NP, estimated the optimized response of brake thermal efficiency (BHTE) 31.18%, brake specific fuel consumption (BSFC) 0.2975 kg/kWh, carbon monoxide (CO) 0.0887%, hydrocarbon (HC) 31 ppm, oxide of nitrogen (NOx) 677 ppm, and smoke level 54.92%. These predicted values were validated with experimental results, and errors were within the range. The nanoparticle combination sample offers improved brake thermal efficiency (BTHE) and lower BSFC rate than the S20 while testing for the optimal parametric condition. Graphical abstract

      Authors: Babatunde S Eweade, Gizem Uzuner, Ada Chigozie Akadiri, Taiwo Temitope Lasisi
      Abstract: Energy & Environment, Ahead of Print.
      Japan's recent enunciation of a “Free and Open Indo-Pacific” policy aims to promote principles such as free trade, freedom of navigation, and encouraging economic prosperity with building commitment to stability and peace connecting the economic hub of Asia to Africa (MFA, 2019). Natural gas use continues to dominate Japan's energy mix despite efforts to improve environmental protection and attain the Sustainable Development Goals (SDGs). Also, increasing production and investment typically leads to a better quality of life and more disposable income for the populace, which promotes economic growth. To this end, the study investigates the relationship between economic growth, trade openness, and natural gas consumption, as well as gross fixed capital formation and carbon dioxide emissions to overcome omitted variable problems to explore the natural gas-economic growth hypothesis in Japan over the period 1980–2020. Empirical results reveal a long-run relationship among the variables under consideration. By applying the Toda and Yamamoto approach to Granger causality testing, a two-sided causality running from CO2 and economic growth was revealed, while a one-sided causality from economic growth to natural gas consumption. This outcome suggests that the natural gas-economic growth hypothesis is not valid for Japan. According to these outcomes, policymakers in the energy sector should consciously diversify their energy portfolio in line with the Sustainable Development Goals (SDGs) for Japan. Also, it is recommended that there should be a provision of access to skilled labor to increase productivity and export finished products to boost a nation's economy.

      Abstract: Energy & Environment, Ahead of Print.
      The present work aims to contribute to the existing literature by assessing the influence of insurance market development on the UAE's environmental quality. This study stands to be the first to evaluate the influence of the insurance market on environmental quality in the UAE. The study used an advanced approach to confirm the cointegrating relationship among selected variables: bootstrap Autoregressive Distributed Lag (ARDL) testing and the Bayer and Hanck test for co-integration. The empirical outcomes reveal that renewable energy consumption stimulates environmental quality in the short and long run. Furthermore, empirical outcomes show that insurance market development has a positive effect on the level of environmental quality in the country. Therefore, policymakers in the UAE are advised to make policies and strategies to reinforce the sustainability of insurance markets that would minimize environmental pollution by giving incentives to whoever contributes minimal carbon and uses eco-friendly materials. This can be achieved through an active role in green investments and product development to promote environmental quality and increase insurers” profitability and credit rating.

      Abstract: Energy & Environment, Ahead of Print.
      Oil shale kerogen is a kind of composite nature of fossil energy polymer. Kerogen pyrolysis is a feasible and alternative strategy to produce fossil fuels from shales. However, the disadvantages including the high energy consumption, the high cost, and the low hydrocarbon conversion, significantly hinder the development and utilization of unconventional hydrocarbon resources. Herein, the hexagonal crystal structural layered double hydroxides (LDHs) with the Ni/Fe ratio of 5.64:2.36 is proposed as pyrolysis catalyst to improve the catalytic efficiency, the selectivity of target hydrocarbons, and lower the temperature for the process of kerogen pyrolysis. As a result, needle-like nanoscale NiFe-LDHs are prepared successfully to perform the fast thermal upgrading of Balikun oil shale kerogen. The catalytic pyrolysis performance has been observed that the temperature for maximum conversion (Tmax) is 401.18 °C, presenting a Tmax reduction of 37.84 °C, the yield of shale oil is increased by 7.83 wt%. And during 350°C– 400°C, a progressive increment of 147.67%, 230.86%, and 310.61% is obtained corresponding to the content of C1-C5, C6-C14, and C14 + hydrocarbons, respectively. This finding enriches the catalyst candidates for kerogen pyrolysis and provides new insights into industrial applications of in-situ pyrolysis technology for oil shale recovery processes.

      Abstract: Energy & Environment, Ahead of Print.
      Taking new energy vehicle (NEV) listed enterprises from 2010 to 2018 as a research sample, this paper empirically analyzes the innovative impact of VC on NEV enterprises by applying the difference-in-difference (DID) model. The results indicate that the intervention of VC has a positive and significant impact on the green technological innovation in NEV enterprises, an impact which is reflected in a significant increase in the number of green invention and green utility model patent applications. Compared with state-owned NEV enterprises, VC plays a more significant role in promoting the green technological innovation of private and foreign NEV enterprises. In the NEV industry chain, VC has significantly promoted green technological innovation of upstream and midstream NEV enterprises. From the perspective of VC, it also finds that, compared with independent and local VC, it is the syndicated and non-local VC that have a more positive and significant impact on green technological innovation in the NEV enterprises. Besides, the high-reputation of VC has not had an “incubating” effect on green technological innovation in NEV enterprises.

      The current study investigates three important characteristics of corporate culture, i.e., information sharing, technological openness, and corporate innovation to address the research gap about how they affect corporate culture to enhance green corporate social responsibility in the automobile sector of China. The data were tested and examined using PLS-SEM. The findings indicate that information sharing, technological openness, and corporate innovation contribute to enhancing green corporate social responsibility. More precisely, the corporate culture encourages information sharing and innovation among employees and connects them to increased corporation operations that may facilitate the acquisition of advanced manufacturing skills. The study demonstrated that corporate culture is critical to effective corporate integration and that information sharing and corporate innovation tend to be powerful determinants of green corporate social responsibility. Additionally, the study emphasized that these characteristics are the source of corporate social responsibility and adopting these characteristics will assist corporations in enhancing the green corporate social responsibility.

      Abstract: Energy & Environment, Ahead of Print.
      The Report: Intergovernmental Panel on Climate Change (IPCC) set a goal global warming of 1.5°C on global temperature change. Extreme climate changes have increased the demand for electricity consumption by people and enterprises. In fact, China's total power generation in 2019 exceeded 25% of the world's amount, and its thermal power generation accounted for more than 70%. Although past research on electricity efficiency seldom discusses the issue of climate change, the topic still remains important. This research thus considers extreme temperature days (climate change variable) as exogenous variable and uses the Two-Stage Meta Under exogenous undesirable EBM model to examine power efficiency in China. The results are as follows. (1) In the west only Qinghai's GDP, CO2, PM2.5, and electricity consumption have technology gap ratio (TGR) efficiency values of 1 in the 5 years. (2) China's electricity consumption has the same trend with the TGR efficiency of CO2 and is higher than PM2.5. (3) The national overall efficiency, meta overall efficiency, and TGR overall efficiency are the worst in China's west region.

      Abstract: Energy & Environment, Ahead of Print.
      In this study, the willingness to pay (WTP) of the Korean people for a flood control policy to prepare for climate change and a policy to reinforce the protection of populations vulnerable to climate change was estimated using the contingent valuation method (CVM). In addition, the appropriateness of the budgets allotted by the Korean government for these two policies in 2021 was examined by comparing them with the benefits to the people at the national level. The average annual WTP per household was estimated to be approximately KRW 27,457 and 25,854 for these two policies. The WTP was found to increase with adverse effects caused by extreme weather conditions; as people developed an interest in climate change, their income level increased and hence they showed preferences for policies by the ruling party. In addition, the benefits of the two policies at the national level were estimated to be worth KRW 573.6 and 540.1 billion, respectively. When the benefits were compared with the amount allotted in the budgets for them, the ratio of the budget to the benefit was found to be 77.55% for flood control in preparation for climate change and 4.46% for the reinforced protection of populations vulnerable to climate change. This confirms that the acceptability of the policy by the populations vulnerable to climate change is high, but the budget is not allocated as per the need.

      Abstract: Energy & Environment, Ahead of Print.
      In order to reveal the effects of diesel and diesel methanol dual fuel (DMDF) on engine performance at different altitudes, especially on combustion stability. In this study, a comparison of experimental research on characteristics of combustion, economy, and emissions for a turbocharged DMDF at various simulated altitudes (10m, 700m, 1670m, and 2400m) and three working conditions (1200rpm-72 Nm, 1800rpm-158 Nm, and 2200rpm-153 Nm) were conducted and analyzed combustion characteristics, economy and emissions. At 1800rpm and 2200rpm, with the increment of altitude, the peak value of the cylinder pressure, the pressure rise rate, and the brake thermal efficiency (BTE) for DMDF mode were higher than diesel mode, while combustion center (CA50) and combustion duration of diesel mode higher than DMDF mode. At 1200rpm and 1800 rpm, the maximum heat release rate (HRR) of DMDF mode was higher than diesel mode. When the altitude rose from 10m to 2400m, the coefficient of variation of peak pressure (COVPP) of DMDF mode increased while the coefficient of variation of indicated mean effective pressure (COVIMEP) of DMDF mode decreased, which means the combustion of dual-fuel is relatively stable. The exhaust temperature of DMDF mode was lower than that of diesel mode at various altitudes. Compared with diesel mode, NOX and Soot emissions in DMDF model significantly decreased at different altitudes and working conditions.

      Authors: Sehwan Kim, Wooyoung Jeon
      Abstract: Energy & Environment, Ahead of Print.
      The impact of renewable energy on economic growth has been controversial and the possible reason for this is that renewable energy is aggregation of sources with heterogeneous characteristics and different countries have different portfolio of renewable sources depending on their climate condition and technology maturity. This study examines the relationship between renewable energy sources such as solar, wind and bio energy and economic growth in 89 countries. For methodology, this paper adopted Islam's growth equation and performed Dynamic Panel Analysis based on Arellano-Bond GMM methodology. In addition to whole sample analysis, a sub-group analysis is performed between OECD and non-OECD countries, and between energy-importing and energy-exporting countries to examine how the relationship is affected by country's capital accumulation, technology maturity, energy cost, and energy security. The result shows that individual sources have the U-shaped relationships with growth, but the turning points where negative relationship changes to positive vary for different sources. For sub-group analysis, the U-shaped relationship was significant only in OECD countries and energy-importing countries. This shows that high technology development and capital accumulation of OECD countries and high energy cost and vulnerability to international energy market of energy-importing countries makes renewable sources more beneficial to economic growth.

      Authors: Min Bai, Ly Ho
      Abstract: Energy & Environment, Ahead of Print.
      This paper reviews COVID-19 pandemic-related literature to examine its impacts on oil and gold prices during and since the initial outbreak. The literature reviewed covers varying markets, hypotheses, methodologies, robustness checks, and findings. Crude oil is important to everyday life for individuals, businesses, investors, and markets globally. The forces exerted by demand and supply and shocks can greatly increase volatility in oil commodity prices, which has been the case during the COVID-19 pandemic outbreak. Oil has also in the past been used as a risk diversifier in portfolio optimization strategies. Gold has long been seen as a safe-haven asset that investors flee to during economic and financial market uncertainty and turbulence. How did the COVID-19 health crisis affect these two commodities during its initial outbreak and consequent persistence since then' How did government lockdown and restriction measures, monetary and fiscal stimulus packages, and pandemic-related news impact these commodity markets and their movements' Is there a contagion volatility effect between different markets and if so, who have been net transmitters and recipients of these flow-on effects' This literature review offers some insight into the answers to these questions while also highlighting the importance of further study since COVID-19 and its strains are not finished with the world yet.

      Abstract: Energy & Environment, Ahead of Print.
      A scientific assessment of the synergistic effect of the low-carbon city pilot policy in reducing air pollution and carbon emissions is needed to promote carbon peak and carbon neutrality. This study applied the Spatial Durbin Model-Difference in Difference technique to investigate the synergistic effect of air pollution and carbon emission reduction through the implementation of the low-carbon city pilot policy. The main results are as follows. (1) A spatial phenomenon was observed, in which there was a coexistence of urban carbon emissions and air pollution agglomerations. The spatial characteristics of the “symbiotic” carbon emissions and air pollution agglomerations were revealed. (2) The low-carbon city policy significantly reduced CO2, SO2, and PM2.5 concentrations, and the effect of the “co-governance” of air pollution and carbon emission reduction was obvious. (3) There was a clear regional heterogeneity in the synergistic effect of air pollution and carbon emission reduction in low-carbon cities. A stronger incentive effect was apparent in central and western cities, resource-based cities, and key environmental protection cities. (4) To achieve a synergistic governance “sharing” situation, the transmission mechanism of the low-carbon city pilot policy was the reduction of total energy consumption, the promotion of industrial restructuring, the optimization of the factor endowment structure, and the continuous improvement of the urban transport structure and green innovation. Our results not only help advance the research on synergistic reduction of air pollution and carbon emissions, but also can be of interest to low-carbon city policy makers in China.

      Authors: Fengsheng Chien
      Abstract: Energy & Environment, Ahead of Print.
      Environmental degradation has been recognized as a global issue due to high energy consumption and economic growth. This situation needs researchers to focus on, thereby, the current article examined the impact of renewable energy production (REP), energy import, renewable energy consumption (REC), gross domestic product (GDP), inflation, and foreign direct investment (FDI) on the carbon dioxide (CO2) emission in China. The study considered secondary data and extracted it from the World Bank database covering the period 1981 to 2018. The current article has examined the stationarity of the constructs using Augmented Dickey-Fuller tests and investigated the association among constructs using the quantile autoregressive distributed lag (QARDL) model. The data revealed that REP, energy import, and REC, had a significant and negative linkage with CO2 emission in China. In contrast, GDP, inflation, and FDI are linked with CO2 emission in a positive manner. The article also guided the policymakers regarding the policy development related to reducing carbon emissions using renewable energy production and consumption.

      Abstract: Energy & Environment, Ahead of Print.
      One of the biggest environmental challenges for scientists and researchers is to minimize energy crisis by utilizing renewable energy without impacting the climate. Natural dyes based organic solar cells are third generation dye sensitized solar cells (DSSC) which are bio safe, low cost, and relatively easy to fabricate with flexibility than Silicon based solar cells. In this study dye sensitized solar cells are modelled and simulated using diffusion model. The simulations are carried out in MATLAB software to investigate the electrical characteristics. The simulations are performed for three different DSSCs made of pomegranate, beetroot and N-719 dyes. Physical parameters are extracted and their impact on the performance of solar cells is studied. Additionally, the effects of variations in electrode thickness and irradiance are also investigated. The results indicated that short-circuit current, open-circuit voltage and output power increased by decreasing the electrode thickness. Simulated results are in good agreement with the experimental results of preassembled DSSCs. A set of parameters based on electrical considerations is delivered which will not only help to study the impact of physical parameter of DSSC but will also help to control and improve the performance and efficiency of Dye sensitized solar cells.

      Authors: Xia Zebang, Zhang Yi
      Abstract: Energy & Environment, Ahead of Print.
      As an important field, energy trade significantly impacts China and the United States. Energy and climate policies in the U.S. impact China’s energy industry differently. Climate and energy policies have also changed in tandem with changes in the U.S. regime. By comparing the energy policies of the Biden and Trump administrations, the impact of different U.S. energy and climate policies on China’s energy industry was discussed, and the industry's development status was analyzed. In addition, corresponding strategies for China's energy industry's rapid and stable development are proposed. The current research results show that: (i) China has become an importer of traditional fossil energy in the United States since the Trump period, and U.S. energy and climate policies have had different impacts on China’s energy industry; (ii) China's natural gas imports from United States in China rose from 2.19 million tons (Trump period) to 8.98 million tons (Biden period); however, China's oil imports from United States continued to decline, from a maximum of 8.427 million tons (Trump period) to 1.147 million tons (Biden period); (iii) China’s photovoltaic solar cell exports under Biden period increased by 43.7% compared to the Trump period (2020). In addition, United States energy and climate policies will lead to increased demand for photovoltaic solar cells in the global market, which has a positive impact on China's new energy industry represented by solar photovoltaics.

  • Unveiling the asymmetric energy-growth nexus in top oil-importing and

    • Free pre-print version: Loading...

      Authors: Khang Yi Sim, Siok Kun Sek
      Abstract: Energy & Environment, Ahead of Print.
      Conventional panel models that overlook nonlinearity, nonstationarity, heterogeneity and cross-sectional dependency when analysing the energy-growth nexus might produce misleading conclusions. In addressing these issues, this study extends the examination of the nexus by applying nonstationary panel models with common correlated effects (CCE). They involve two estimators, namely CCE mean group (CCEMG) and augmented mean group (AMG) estimators. The main objective is to examine the effects of total and renewable energy consumption on the gross domestic product (GDP) by comparing the top oil-importing and top oil-exporting countries. The datasets are in annual frequency, ranging from 1992 to 2015. The results are compared to ordinary least squares (OLS)-type models that serve as benchmarks. This study innovates the models by incorporating the asymmetric effects of energy consumption into the estimations. The findings reveal a positive correlation between total energy consumption and GDP for both panel groups, and capital input is one of the determinants in all cases. The results disclose evidence of the asymmetric effects of total and renewable energy consumption. The positive impact of total/renewable energy consumption decreases for the top oil-exporting group is more apparent than its increases, signifying the importance of energy conservation. For top oil-importing nations, increased renewable energy consumption impedes the GDP, but the increase in total energy consumption accelerates it. Energy efficiency policies should be implemented in oil-importing countries since the positive impact of total energy consumption is smaller than in the other group.

      Authors: Kedong Yin, Yuqing Miao, Chong Huang
      Abstract: Energy & Environment, Ahead of Print.
      The conflict between rapid economic development, resource mismatch, and ecological damage is growing more severe. Industrial structure upgrading, as a bridge between economic activity and the ecological environment, is a crucial strategy for solving ecological and environmental problems. Based on the mediating effect and threshold models, this study selected 30 provincial panel data points in China from 2000 to 2020 to study the impact of environmental regulation and technological innovation on industrial structure upgrading. According to the findings, environmental regulation has a “U” shaped impact on industrial upgrading and passes the three threshold tests, with technological innovation playing a partially positive mediating role. There is regional heterogeneity in the impact of environmental regulation on industrial upgrading, with a “U” shaped impact on the eastern regions; there is inhibited industrial upscaling in the central and western areas. Foreign trade hinders industrial development in the eastern region but promotes rapid development and achieves structural adjustment in the central and western areas. The expansion of fixed asset investment hinders industrial restructuring. Government regulation can encourage industrial structure upgrading in all regions. We propose policy recommendations based on China’s current situation. The development of technological innovation should be promoted, and environmental rules should be differentiated according to local conditions. This study has a certain guiding significance and reference value for balancing environmental governance and economic development, effectively implementing an innovation-driven development strategy, and formulating China's regional development strategy.

      Abstract: Energy & Environment, Ahead of Print.
      The present millennium records the most devastating effects of global warming than what was evident in the pre-industrial era. The pervasive effects of global warming have raised concerns about the sustainability of the present and future generations. Hence, researchers are working assiduously towards proffering the most effective method of halting the surging emissions from global, regional, and national angles. This study contributes to the extant literature by providing the first empirical verification of how renewable energy, technological innovations, trade openness, and transport services impact carbon emissions in Germany. The empirical evidence is anchored on annual time series data from 1990 to 2020 estimated using the novel nonlinear ARDL to explore the positive and negative shocks associated with the short and long-run nexus. The wavelet coherence estimator is equally for ascertaining the multiple time scales in the time series and extends the knowledge frontier to the literature. The following findings are eminent from the overall analyses. First, long-run cointegration is supported among the variables of interest Second, only the adverse effects of renewable energy and technology are substantial enough to mitigate carbon emissions. The trade-induced emissions are established with the positive impacts of trade openness on carbon emissions. Transport services contribute significantly to carbon emissions in the long-run and short-run periods. However, mitigating effects of small magnitude are apparent in the long-run due to the perceived transition to green transportation. Policy implications supporting the transition to 100% renewable energy and green transportation are significant steps towards achieving Germany's carbon neutrality target.

      Abstract: Energy & Environment, Ahead of Print.
      In fact, current water supplies due to natural constraints or lack of infrastructure (or both) cannot be provided in a sustainable manner for all increasing and competing uses (e.g. residential, industrial, agricultural). While promoting Penghu's low-carbon islands, in a water-scarce environment, it is the motivation of this research to take into account the development of water resources and lower energy consumption costs. The seawater desalination plant water production technology is improved, the cost of water production is reduced. This research uses a genetic algorithm (GA) to optimize the recovery rate to solve the minimum Specific energy consumption (SEC) value, and then, according to the required water production, the optimal flow rate of raw seawater of the high-pressure pump is obtained, so as to minimize the energy consumption of the reverse osmosis (RO) system. The energy recovery device has a great effect on reducing the energy consumption of the RO system, and it can be seen from the results that the higher efficiency does greatly reduce the energy consumption of the SEC and water production under the different energy recovery device efficiency. Calculated using genetic algorithms, and the SEC is 3.275 and the recovery rate is 45.1%, and the water production energy consumption is 2.35 kWh/m3. Scheme B changed the efficiency of the energy recovery unit to 97.22%, resulting in a SEC of 1.819 and a recovery rate of 25.3%, and a water production energy consumption of 1.31 kWh/m3. Finally, challenges and research gaps are also proposed.

      Abstract: Energy & Environment, Ahead of Print.
      The carbon emission trading scheme (ETS) and tradable green certificate (TGC) system have been widely used to encourage renewable technology and mitigate greenhouse gas emissions. Previous studies have discussed the interaction between these market-based instruments and the electricity market from a theoretical perspective. This research contributes to the literature by empirically examining the interplay of carbon market, the TGC market, and electricity market using a vector autoregressive (VAR) model to investigate the price transmission between different markets. A VAR-BEKK-GARCH model, based on discrete wavelet decomposition, was used to reveal the spillover effect between the three markets over multiple time scales. Based on evidence from the partially deregulated electricity market in South Korea, we do not find a significant short-term interaction between carbon market and the TGC market through the price transmission. However, the analysis over multiple time scales demonstrates that the return spillover between the carbon market and the TGC market is positive and bidirectional in the medium-term and long-term. In addition, the policy integration may create higher price risks to the carbon market and the TGC market, resulting from long-term risk spillovers. We explain these contrasting findings and discuss implications for the future deployment of these policies.

      Abstract: Energy & Environment, Ahead of Print.
      This study aims to determine the potential for improving regional cooperation and clean energy generation in the South China Sea (SCS) through Offshore Wind Energy (OWE). The literature review depicts the broad relationship between renewable energy and regional cooperation. The study identifies three variables-great game of geopolitics, geo-economics, and NEO politics- to arrive at a concept of wind-blindness. It refers to the attempt (of the countries involved) to downplay the existing wind resources and avert attention from them to safeguard the region's strategic military importance, existing trade routes, and rich availability of marine resources. Addressing these concerns could strengthen cooperation between the claimant states for technology, knowledge, and practice sharing, to ensure a sustainable South China Sea region. China's investments in OWE in the South China Sea have the potential to meet the Sustainable Development Goals” target of cleaner, accessible, and affordable energy. Finally, the paper suggests that renewable energy development in the region can reduce the maritime transport of fossil fuels, reducing the carbon footprint.

      Abstract: Energy & Environment, Ahead of Print.
      The global economy is experiencing the most challenging era of climate change beyond what is evident in the pre-industrial age. Although Africa's share of global greenhouse gas (GHG) is minimal, the ensuing effects hit hard on the continent. Hence, the present study provides the first comprehensive empirical assessment of environmental sustainability in Africa within the novel STIRPAT framework. This study critically examines the impacts of natural resource dependence, renewable energy, urbanization, technological innovations, and structural transition on environmental pollution proxied by carbon emissions, ecological footprint, and PM2.5 air pollution from 1990 to 2019 in five top carbon-emitting African countries. The empirical evidence is based on advanced panel estimators comprising CS-ARDL, CCEMG, and AMG robust to cross-sectional dependence (CSD). The quantile regression efficient for exploring the conditional distribution effects is equally employed alongside Dumitrescu-Hurlin panel granger causality test. The preliminary tests reveal the presence of CSD and heterogeneity of the series, which led to the conduct of second-generation unit root and cointegration tests. The main empirical results show that renewable energy, technological innovations, and structural transition reduce environmental pollutants from surging based on the observable negative signs. By implication, these indicators support Africa's path to environmental sustainability. On the flip side, resource dependence and urbanization amplify the surge. The feedbacks from quantile regression provide sturdy support for the main estimators. The granger causality feedbacks support the existence of bidirectional and unidirectional causality among the variables. Based on the findings, policies that promote sustainable environment are formulated.

      Authors: Pragya Thakur, Vincent Herald Wilson
      Abstract: Energy & Environment, Ahead of Print.
      Community solar has the capability to broaden solar accessibility and convalesce financial feasibility in comparison to conventional and commercial solar options and holds the potential to be part of the energy mix. Community solar avails ingress and affordability to solar power for those who may not be able to exploit it either due to financial or location constraints. Parallelly, it solves the issues related to electrification, fossil fuel crisis and greenhouse gas emission, contributes to sustainable development goals (SDG 7 and SDG 11), and realization of net-zero goals, however, the presence of barriers makes the adoption or scaling of community solar difficult. This research work intends to identify twelve crucial barriers for the adoption of community solar on the basis of the literature review and the perception of experts in the energy system. In this paper, we adopted hybrid Interpretive Structural Modeling (ISM) - Decision Ma king Trail and Evaluation Laboratory (DEMATEL) approach for comprehension of the causal and hierarchical relationships among barriers for community solar adoption. The result suggested that lack of consumer awareness, lack of regulations and policies addressing community solar and lack of business model are the most influential barriers as depicted in ISM-DEMATEL based methodology. With the presented novel method, policy-makers, utilities and communities can liaise, coordinate and practice the system-wide advantages of community energy projects. It can also aid the public sector in comprehending the barriers and requirements of people.

      This paper aims to investigate the impact of social, economic, and political variables on per capita ecological footprint consumption in the NEXT Eleven economies over the period 1984- 2018. The study utilized the dynamic heterogeneous panel estimators of Cross-Sectionally Augmented Auto-regressive Distributive Lag (CS-ARDL) along with the estimator with a multifactor error structure. The study also estimated the cross-Sectionally augmented distributed lag (CS-DL) model while for robustness check the augmented mean group (AMG) and cross-Sectionally augmented error correction method (CS-ECM) is also considered. The study finding maintains that the impact of GDP per capita, multifaceted phenomena of financial development, and military expenditure is positive and significant suggesting that a unit increase in these variables deteriorates the environment in the NEXT Eleven economies. In contrast, higher life expectancy and government stability improve the environment in the long run. The findings of the study suggest that eco-friendly technologies to be used in the production process, as well as projects using outdated technologies, should be discouraged along with the assurance of government stability and reduction of military expenditure in the NEXT Eleven economies.

      Abstract: Energy & Environment, Ahead of Print.
      The digital transformation of global economic and social activities brought about by advanced information and communication technology (ICT) may have a profound impact on sustainable economic development. This research measures the digitalization of the economy and society in cities of China based on Internet-related indicators and digital financial development and investigates the economic and environmental effects of their digitalization. The empirical results show that digitalization has significantly improved green economic efficiency (GEE), and this finding remains valid after a series of robust analyses. However, there is regional heterogeneity in the improvement effect of GEE. The green effect of digitalization is significant only in the cities with a high degree of economic servitization, capital-abundant cities, and eastern cities. Although digitalization has promoted the green development of the urban economy, it also has a negative spatial spillover effect on the GEE of neighboring cities. One explanation is that cities are shifting polluting industries to other areas during the process of digital transformation.

      Abstract: Energy & Environment, Ahead of Print.
      In the context of ecological environment construction, how to create a new development pattern in which environment and economy are coordinated has become an important goal of the Chinese government. From the perspective of the symbiotic development of resource-based industries and non-resource industries, this study discusses the path of green credit optimization of energy consumption structure by using the space Durbin model, based on the panel data from 30 Chinese provinces from 2006 to 2019. The study results are as follows: Both green credit and energy consumption structure have a significant positive spatial correlation. Furthermore, the energy consumption structure of local and adjacent areas is significantly optimized by green credit. Additionally, for non-resource-based regions, although green credit has no spatial spillover, it can significantly improve the local energy consumption structure, while green credit in resource-based regions significantly inhibits the optimization of the energy consumption structure in local and adjacent regions. Finally, from the perspective of the symbiotic development of resource-based industries and non-resource industries, although green credit can significantly improve the local energy consumption structure, it will inhibit the optimization of the energy consumption structure in adjacent areas. Therefore, government departments not only need to implement green credit policies according to local conditions but also actively guide exchanges and cooperation between resource-based industries and non-resource industries. This move promotes the symbiotic development of resource-based industries and non-resource industries and simultaneously improves the utilization efficiency of green credit, and optimizes the energy consumption structure.

      Abstract: Energy & Environment, Ahead of Print.
      To avoid severe environmental pollution, the government actively implements environmental regulation (ER) to ensure that enterprises carry out green innovation (GI), and the public participation in supervision has become an important part of the process of environmental governance. In this study, we incorporated the three parties of enterprise, government, and public into one framework and constructed a tripartite evolutionary game model. On this basis, combined with the system dynamics simulation, the behavioral strategy selection and influencing factors of the tripartite agents were analyzed. The results indicate that no matter what the initial strategy of the enterprise, government, or the public is, after a continuous evolutionary game, the three parties will reach a stable and balanced state, that is enterprises carry out GI, governments implement ER, and the public participates in supervision. Whether the government implements ER has a great impact on the enterprises’ decision-making. The public's strategic choices have no obvious influence on the governments’ strategies. Notably, GI costs and government subsidies and fines are the main factors that affect the enterprises’ GI initiatives. Government subsidies are suitable for short-term and appropriate subsidies. Finally, we proposed strategies that could optimize the management processes of ER, while ensuring the effective contributions of enterprises, governments, and the public in a seamless manner. Our study can be used as a reference for the implementation of effective ER and serve policymakers in decision-making, to promote sustainable development at a regional and global scale.

      Abstract: Energy & Environment, Ahead of Print.
      With the signing of the Paris Agreement in 2016, countries began to explore new economic models to get rid of the high emissions and high pollution caused by the traditional extensive economic model. Circular economy (CE) is regarded as an important way to achieve carbon neutrality, yet there is little literature has explored the relationship between the two. This paper aims to provide evidence and suggestions for developing circular economy strategies in emerging developing countries such as China by exploring the relationship between circular economy and carbon emissions. In this study, urban carbon emissions were measured by using high-resolution carbon emission data and the circular economy of 285 cities in China from 2009 to 2018 was estimated using a data envelopment analysis (SBM-DEA) model based on a super effective slackness measure. Then, the spatial impact of the circular economy was analyzed based on the spatial Durbin model. The empirical results are as follows: first, carbon intensity shows a positive spatial correlation, with most cities clustered in high-high (H-H) and low-low (L-L) types. Second, it was found that CE has a significant negative impact on the carbon intensity of local cities and neighboring cities. Third, based on regional heterogeneity, CE has significant negative direct and indirect effects in central and western cities. In contrast, CE has only significant direct effects (negative values) in eastern cities.

  • Public perception of oilfield produced water: The case of California's
           Central Valley

      Authors: Sumita Sarma, Nyakundi M. Michieka
      Abstract: Energy & Environment, Ahead of Print.
      Oilfield Produced Water (OPW) has been identified as a viable solution to mitigate water scarcity in California‘s Central Valley. However, consumer perception on the use of OPW outside of the oil and gas industry remains unknown and poses a hurdle for large-scale adoption. This paper, based on 134 randomly selected residents of Kern County (California‘s largest oil-producing county and top agricultural region), examined attitudes towards OPW reuse. In the survey, more than half (52.3%) of participants said that they have heard about oilfield-produced water and other reclaimed waters. Findings also suggest that participants mostly preferred rain and stormwater, and interestingly scored OPW higher than industrial and black waters for irrigation purposes. Around 67% of the participants supported the use of oilfield-produced water for irrigating crops. Younger people (18–29 years) expressed greater concern about using OPW compared to the older residents. Given the drought conditions in Central Valley, policymakers might need to focus on a circular economy and mandate the use of OPW in Central Valley considering that this region‘s economy lies at the nexus of the O&G and agriculture industries.

      Abstract: Energy & Environment, Ahead of Print.
      This paper proposes an energy management system (EMS) in smart grid based on Internet of Things (IoT) configuration using hybrid approach. The proposed approach is joint execution of Multi-fidelity meta-optimization and Turbulent Flow of water based optimization (TFWO), hence it is known as M2FWO technique. The main objective of this proposed EMS is to better manage power with the resources of Smart Grid by constantly monitoring data from the IoT-based communication framework. Here, each home device is connected to data acquisition module is utilized to facilitate the demand response (DR) growth for energy management system in smart grid. The framework collects DR from every smart home device and then transmits the data to the centralized server. The transmitting data is enabled by M2FWO method. The smart grid IoT framework enhances the feasibility of these networks makes better use of obtainable resources. The proposed system is in charge to satisfy the total supply with energy requirement. Finally, the proposed model is stimulated on MATLAB/Simulink site, then the efficiency is examined with existing methods.

      Authors: Ahmed Elsayed Mahmoud Fodah, Taha Abdelfattah Mohammed Abdelwahab
      Abstract: Energy & Environment, Ahead of Print.
      Higher heating value, energy and exergy analysis of bio-oil and biochar from microwave pyrolysis have been assessed. The energy efficiency for the pyrolysis system has been analyzed by the comparisons of energy based on heating values. The exergy analysis was done using standard relationships by the fraction of energy actually available for practical uses as biofuel. The yield of bio-oil and its higher heating value (HHV) were increased by 2–13% and 25–130% respectively when the microwave power increased from 500 W to 700 W, then both are decreased at 900 W. Using activated carbon (AC) had a remarkable effect on increasing the yield and HHV of bio-oil by 18–31% and 3–7 times respectively more than other cases. By using the additives, the yield of biochar decreased remarkably, while its HHV increased by 12%-40% compared to without additive. The maximum energy and exergy rate (1.74 MJ/h) of the bio-oil were obtained at 700 W level of microwave power using AC additive, while for biochar were 1.95 MJ/h and 2 MJ/h when no additive used. The maximum values of energy and exergy of the bio-oil were computed to be 27% and 26% respectively at 700 W using AC as an additive. The maximum values of energy and exergy efficiency of biochar were calculated to be 33% and 32% respectively when pyrolyzed at 500 W using AC. The energy and exergy efficiencies of the pyrolysis system were computed to be maximum value of 53.3% and 52.8% respectively at 700 W using AC additive.

      Authors: Muhammad Ahmad, Aamer Shahzad, M. Nafees Mumtaz Qadri
      Abstract: Energy & Environment, Ahead of Print.
      In this paper, an attempt has been made to highlight major developments of vertical axis wind turbines (VAWTs) in the last few decades. The effects of various design parameters such as airfoil, number of blades, solidity, aspect ratio, blade helicity, and overlap ratio have been critically analyzed. Wind energy is the most promising renewable, cost-effective, efficient, and accessible source for both domestic and commercial applications. Horizontal axis wind turbines are highly developed and are being used for medium-to-large scale power projects. VAWT are considered viable options for urban and semi-urban areas. These turbines have several characteristics, such as omnidirectional, power generation in weak and unstable winds, esthetically sound, safety, and low noise. Darrieus turbines with a fixed blade-type have starting problems at low wind speeds. Savonius turbines have good starting capability; however, their power coefficients are lower than other types of VAWT. To overcome the shortcomings of conventional wind turbines, an innovative engineering solution was sought in the design of hybrid VAWT. The analysis revealed that hybrid wind turbines have addressed the deficiencies to an extent; however, the overall performance is still less than that of conventional wind turbines. Several recommendations have been made based on state-of-the-art information from the perspective of future studies and acceptability. It was concluded that vast opportunities for wind turbine applications are available in urban areas; however, further academic research is required on critical aspects such as self-starting at low wind speeds, efficiency, structural reliability, design improvement for aerodynamic performance, and wind resource assessment.

      Authors: Wen-Quan Hu, Jingyu Zhao, Lexin Zhao
      Abstract: Energy & Environment, Ahead of Print.
      This paper exploits a quasi-natural experiment in China, the environmental protection tax reform, to examine the effect of environmental regulation on corporate green investment. Based on Chinese listed company data and the multi-period DID method, we find the enhancement of environmental regulation harms corporate green investment in a short time, and green investments in the treatment group were reduced by 19.57 million (RMB) on average. Further exploring and examining the potential mechanisms of the above effect, we find the above effect is caused by the suppression effect of financing constraints and the crowding-out effect of research and development (R&D) expenditures. We also analyze the heterogeneity of enterprise ownership, enterprise size, and enterprise location, and find that non-state-owned enterprises, small-sized enterprises, and enterprises in the eastern region will experience a greater reduction in green investment when environmental regulation is enhanced. Based on the above findings, we put forward corresponding policy recommendations.

      Abstract: Energy & Environment, Ahead of Print.
      A green economy refers to a modern form of harmony between the environment and the economy. China showing the fastest economic growth in the world has entered into a new phase of advance, facing a critical industrial transformation and progression. The paper aims to analyse China's green economic development considering the differences in development of regions. The study applied the ultra-efficient slacks-based measure model to scrutinize China's green economic development efficiency. Dagum Gini coefficient and Kernel density methods are used to estimate spatial characteristics, local adjustments, and dynamic evolution trends. The analysis is based on an annual dataset of 30 Chinese provinces from 2010 to 2019. The findings did not confirm extensive China's green economic development. In contrast, the development efficacy reveals an influential drive over the years. Regional green development is detected as unstable and diverges due to interregional differences. The findings showed that environmental regulation, government investment, industrial structure, education development were 0.0648, 0.00154, 0.0035 and 0.118 (significant at 5% and 1%), respectively. Besides, they stimulate the green economic development in the analysed regions. However, urbanization and openness of economy had the negative value. It confirmed their restriction impact on the green economic development. In addition, the findings showed that ongoing Chines policy on management of environmental development is the priority direction and provoke the declining the environmental pollution. Besides, the modernization and optimization of the Chinese industry structure stimulate the further green economic progress.

      Abstract: Energy & Environment, Ahead of Print.
      Photovoltaic thermal heat pumps are conducive to the environment and have drawn much attention due to their great potential in buildings for energy generation and saving of land. This paper puts forward the façade-mounted photovoltaic integrating air chamber cooled by refrigerant-based heat pump. The integrated photovoltaic/thermal (PVT) on the building facade is not only thermally efficient but also results in ambient fresh air cooling, hot water, and electricity production. This paper investigated the performance of façade mounted photovoltaic integrating air chamber by heat pump, which results in a multi-energy generation. The working mode and description of the façade-mounted photovoltaic integrated air chamber by heat pump during summer are presented. Finally, the system performance was analyzed underexposed weather conditions for electrical performance, hot water production, and cooling of hot fresh air. It was found that the average and minimum temperatures of the cooling air through the air chamber reached 21.7 °C and 15 °C, respectively. The average electrical, thermal, and overall efficiencies of the façade-mounted photovoltaic thermal system were 8%, 77.6%, and 98%, respectively. The average coefficient of performance (COP) of the heat pump during water heating was 4.41.

      Abstract: Energy & Environment, Ahead of Print.
      Environmental innovations, investments, and expenses have been identified as an efficient and reliable way of addressing ecological issues. Nevertheless, how environmental innovations, investments, and expenses may influence the level of environmental pollution in European nations and whether the outcome may fluctuate among various environmental innovation indicators remain to be inspected. Therefore, this research is designed to empirically scrutinize the influence of environmental innovations, environmental investment, environmental expenditure, research and development (R&D) expenses, and foreign direct investment (FDI) on renewable and non-renewable energy in a sample of 15 European countries during the period from 2005 to 2018. To achieve this, we apply robust panel econometric estimation techniques. After testing the stationary property of the series, the findings of the Pedroni cointegration test disclose the presence of a long-run stable connection among the series. The empirical results from the ARDL, FMOLS and DOLS regression show that the impact of environmental innovations, environmental expenditure, R&D expenses, and FDI help to reduce overall non-renewable energy and promote renewable energy. In contrast, environmental investment significantly increases non-renewable energy and diminishes renewable energy usage.Moreover, the findings of Dumitrescu and Hurlin's tests discover a unidirectional causality running from non-renewables and renewables towards environmental investment, environmental expenditure, and FDI. Additionally, bi-directional causality is found between environmental innovations R&D, with both non-renewable and renewable energy utilization. Furthermore, we summarize by arguing that the efforts toward efficient and sustainable use of energy by reducing the combustion of non-renewable energy sources should support modern and innovative strategies by ensuring the transformation of non-renewables with renewable energy sources.

      Abstract: Energy & Environment, Ahead of Print.
      The availability of accurate and reliable solar radiation data is very important to explore solar energy potential for commercial power plants. This study presents the validation of global horizontal irradiance (GHI) from McClear model under clear-sky and all-sky conditions against measured data for complex topography of Pakistan. The McClear GHI shows good agreement with measured GHI under clear-sky conditions for nine stations and good correlation was achieved with correlation coefficient ranging from 0.972 to 0.992. The relative mean bias error (rMBE) and relative root mean square error (rRMSE) using GHI data having temporal resolution of 10 minutes was ranging from −2.3 to 6.4% and 3.6 to 7.8% respectively. A seasonal statistical analysis shows variation of errors during seasons, significant variation of errors was observed for monthly statistical analysis, the overall errors for all stations were maximum in January and minimum in June. Cloud fraction (CF) from three state-of-the-art datasets (ERA-5, MERRA-2 and MODIS) was incorporated into McClear clear-sky GHI (GHIMC,clear-sky) to derive commercially resourceful all-sky GHI data (GHIMC,all-sky) using a noval approach. The rMBE of GHIMC,all-sky using CF from ERA-5, MERRA-2 and MODIS ranges from 0.1 to 8.4%, 0.1 to 14.1% and 0.2 to 16.8% respectively. The application of ERA-5 cloud fraction shows good correlation with correlation coefficient ranging from 0.871 to 0.966 and gave best results as rMBE for all stations is less than 4% except one station, the long-term GHIMC,all-sky data can be used for the solar resource assessment of Pakistan in the absence of measured data.

      Authors: Wang Rongjuan
      Abstract: Energy & Environment, Ahead of Print.
      Few studies explored the interaction effect between policy instruments and the policy environment on environmental governance. Based on policy instrument theory, this paper conducts fuzzy set qualitative comparative analysis (fsQCA) to explore the combined effect of policy instruments and the policy environment on the environmental governance efficiency of local governance. This study found four effective configurations of local government environmental governance, which can be summarized as the mandatory mode and the cooperative mode, and three inefficient configurations that can be summarized as the out-of-control mode. The results show that the regions adopting the mandatory mode are economically underdeveloped, while the regions using the cooperative mode are developed. Besides, local government competition leads to the softening of policy instruments, while government-enterprise collusion exacerbates the failure of environmental policy instruments. This paper summarizes the effective modes and reveals the reasons for the low efficiency of local government environmental governance in China. The conclusions provide not only empirical evidence for the study of policy instrument theory but also beneficial insights for the selection of environmental policy instruments and environmental governance practice.

      Authors: Ajay Mittal
      Abstract: Energy & Environment, Ahead of Print.
      Energy is very vital for the economic development and prosperity of any nation. Expanding a country's use of renewable energy sources can help it meet its current and future energy needs, as well as spur economic growth. Sustainable energy supply, electrification rate, population shifts, and per-capita power use affect economic development and prosperity. Electricity use is a key sign of a country's economic growth, and as the economy grows, so does the need for energy. Electricity generation relies on the availability of primary sources, implementation of technology as well as on policy imperatives. The South Asian Association for Regional Cooperation is the regional intergovernmental organization and geopolitical union of states in South Asia. Its member states are India, Afghanistan, Bhutan, Bangladesh, Nepal, Maldives, Sri Lanka, and Pakistan. SAARC countries are wealthy in natural resources, yet economic growth is a difficulty. This study aims to assess the solar energy potential of SAARC countries, which has received little attention. Prior research on solar energy possibilities in SAARC concentrated on one country or group. According to the study, SAARC countries rely heavily on imported fossil fuels and a single energy source. Renewable energy sources, especially solar energy, are important for their sustainable expansion, diversity of energy basket, energy security, and fulfilling rising electricity demand. The SAARC region has superior daily average horizontal sun irradiances than the UK and Germany, indicating untapped potential for solar photovoltaic systems. This study aims to encourage stakeholders to execute efficient solar energy governance planning for sustainable growth.

      Authors: Uğur Ursavaş, Veli Yilanci
      Abstract: Energy & Environment, Ahead of Print.
      This study investigates the convergence in ecological footprint per capita across Southern Common Market countries over the period 1961–2016 within the framework of the environmental convergence hypothesis. However, unlike the existing literature, which mainly tests the convergence for the overall period, this study follows a different path. First, the time series is decomposed into different frequencies using the discrete wavelet transform method. Then, using the Fourier Augmented Dickey-Fuller and Augmented Dickey-Fuller unit root tests, convergence in ecological footprint per capita is tested for different time scales; short-run, medium-run, and finally long-run. The results indicate that countries show different convergence tendencies at different time scales. While the results support the convergence hypothesis for all countries in the short-run, the convergence hypothesis holds for only four and three of the five countries in the medium and long-run, respectively. Besides, the results show that the convergence hypothesis holds for only Uruguay for the whole period.

      Abstract: Energy & Environment, Ahead of Print.
      Solar energy is the powerhouse where all potential and classified renewable energies lug their sources. The energy transformation from the Sun to electricity requires an adequate control scheme to maximise the generated power and enhance the system efficiency. Besides, more than half of solar irradiation on conventional PV panels is lost. The PV/T modules have been introduced to convert the lost irradiation to heat. Thus, a systematic review of system components, development, and strategies for grid-connected solar Photovoltaics (PVs) plants is presented. Two solar PVs, traditional PV and thermal (PV/T), are evaluated. Each grid-tied PV component is considered a subsystem to analyse the potential improvement of grid-connected PVs. This is from solar resources to grid-tied PV inverter techniques. An intensive assessment of the system improvements is presented to evaluate PV plants’ benefits, challenges, and potential solutions. The improvement trends for the novel generation of grid-connected PV systems consist of applying innovative approaches. It is also found that intelligent strategies optimally ensure the overall efficiency of grid-tied PVs using real-time control and measurement under innovative applications and technologies. These methods effectively assist in enhancing grid-tied diverse solar power approaches. Therefore, this paper would offer a significant foundation for advanced research into the subject of grid-tied PV and PV/T and their innovation and/or technology development.

      Abstract: Energy & Environment, Ahead of Print.
      Climate change remains one of the world’s significant threats today, and thus Sustainable Development Goal (SDG) 13 prioritizes countries to reduce global greenhouse gas emissions and mitigate climate change by 2030. Recent studies have scrutinized the impact of Information and Communications Technologies (ICTs) on the environment. However, the majority of these studies assumed that the environmental impact of ICT is homogenous across countries. This study, therefore, investigated the impact of ICT on environmental degradation, considering the difference in ICT quality among countries. Applying a panel dataset of 110 countries between 2000 to 2018 and the instrumental variable generalized method of moments (IV-GMM) technique, the findings revealed that ICTs improve environmental sustainability in countries with high ICT quality while degrading the environment in countries with moderate and low ICT quality. The results of the causality analysis also showed bi-directional causality between ICT and carbon emissions in countries with high and moderate ICT quality, while there is a uni-directional causality running from carbon emissions to ICT in countries with low ICT quality. Policies that enhance ICT usage through low pricing were recommended for moderate and low ICT quality countries to help mitigate environmental degradation.

      Abstract: Energy & Environment, Ahead of Print.
      A hybrid technique is proposed for the effects of different roll-out techniques for charging the infrastructure that enables large-scale introduction of electric vehicles (EVs). The proposed hybrid technique is the combined execution of both Radial Basis Function Neural Network (RBFNN) and Student psychology optimization algorithm (SPOA), together called as RBFNN-SPOA strategy. The proposed method contains 3 kinds of agents operate in the environment from which charging stations is located. The communication among these agents are simulated in 3 ways. They are (1) charging process from which the EV driver cooperates with available charging stations and other electric vehicle drivers, (2) the process of purchasing a vehicle of non-electric vehicle car owners from which they take current charging infrastructure utilization into account, (3) the installment process of new charging stations through charging point operator (CPO) is based on placement tactic depends on charging station (CS) utilization. Firstly, a larger dataset on real charging patterns are utilized to design the charging behaviour of agents by RBFNN. Secondly, the proposed approach contains significantly more communication among electric vehicle drivers compared to existing approaches and also more precisely specifies the difficult system of on-street electric vehicle charging at an urban context. Thirdly, the relation among charging infrastructure and electric vehicle adoption based on experimental choice, while the existing methods provides assumptions by using SPOA. Finally, the proposed approach is implemented in MATLAB or Simulink platform and its performance is compared with existing approaches.

      Abstract: Energy & Environment, Ahead of Print.
      This study examines the effect of urbanization, institutional quality and other variables on environmental sustainability risk among economies in Sub-Saharan Africa (SSA). Environmental sustainability risk is examined from three main perspectives – emission of gases inimical to the environment (CO2 emissions), exploitation of land and water resources (ecological footprint) and exploitation of resources devoid of the requisite savings and education expenditure (genuine sustainability risk). Empirical analyses were performed using the Limited Information Maximum Likelihood (LIML) Instrumental Variable estimation technique. Estimated results suggest that urbanization, population growth and increase commodity prices on the global market (for key export commodities) worsen CO2 emissions among economies in the sub-region. The results further suggest that urbanization, population growth, governance and institutional structures increase resource exploitation. Additional results suggest that institutional quality lessens adverse effect urbanization has on environmental sustainability risk (CO2 emissions) and genuine sustainability risk; but exacerbates the impact urbanization has on ecological footprint. Given these findings, this study recommends conscious efforts at improving governance and institutional structures among governments in the sub-region to lessen adverse effect of urbanization and population growth on environmental sustainability risk.

      Abstract: Energy & Environment, Ahead of Print.
      In order to avert global climate change, the promotion of renewable energy is getting more attention from government and policymakers. There are many factors that can account for the determinant of renewable energy development. While the drivers of renewable energy development have been extensively examined, the influence of governance quality on renewable energy development is very scanty. To fill the gap in the literature, this study examines the influence of governance quality on renewable energy development in 42 African countries over the period 1996–2020. The empirical evidence is based on the panel corrected standard errors (PCSE) estimation technique to account for cross-sectional dependence. The results show that the impact of governance quality on renewable energy development is negative and statistically significant. This means that as governance quality increases, renewable energy development decreases. This is not surprising given the fact that governance quality in Africa is substantially low. In other words, the results imply that governance quality in most African countries still promote non-renewable and energy intensive production system.

      Authors: Yong Liu
      Abstract: Energy & Environment, Ahead of Print.
      China is a major energy consumer, however, related empirical research on China's unequal energy consumption is very limited. Therefore, according to the data from 30 provinces and cities, this study aims to establish a simulation model to analyse the Gini coefficient (the Lorenz curve) of China's energy consumption, and identify the main factors affecting the Gini coefficient through dynamic scenario analysis. During the simulation cycle (from 2022 to 2081), the average Gini coefficient of energy consumption fluctuates between 0.30 and 0.41, which indicates the inequality is slightly high. But the maximum value fluctuation ranges from 0.40 to 0.50, which indicates the inequality is high. The author also found that three factors—technological level, government subsidies, and growth rate of energy supply—can significantly affect the Gini coefficient of energy consumption. It is necessary to promote the technological level, increase subsidies for energy production, and promote the growth of total energy supply to significantly reduce inequity in energy consumption.

      Authors: Ugur Korkut Pata, Atike Elanur Hizarci
      Abstract: Energy & Environment, Ahead of Print.
      Several researchers have focused on the environmental Kuznets curve (EKC) hypothesis to analyze environmental degradation using carbon dioxide (CO2) emissions and ecological footprint as dependent variables. However, analyzes based on these variables neglect the supply side of environmental sustainability. To address this shortcoming, this study aims to examine the determinants of the ecological footprint pressure index (EFPI) in the context of the EKC hypothesis. The EFPI provides a more detailed picture of environmental issues by considering both ecological footprint and biocapacity. Thus, the study aims to add scientific value to the existing literature by analyzing the EFPI under the EKC hypothesis for the first time. Building on this, our research investigates the effects of economic complexity (ECX), per capita income, and renewable energy consumption (REC) on the EFPI by adopting a novel econometric approach. The results of the Fourier autoregressive distributed lag (ARDL) method show a cointegration relationship between income, ECX, renewable energy and EFPI in Germany, Switzerland and Sweden. The long-term elasticities indicate that ECX reduces the EFPI in Germany and Switzerland, while renewable energy mitigates environmental pressure in Switzerland and Sweden. Our findings also confirm the validity of the EKC hypothesis for Germany and Sweden. Based on these findings, the study suggests that ECX, renewable energy and economic growth can all be used as policy instruments to reduce environmental pressure in the three member states of the European Union.

      Authors: Xiaorui Liu, Wen Guo, Qiang Feng, Peng Wang
      Abstract: Energy & Environment, Ahead of Print.
      Given the urgent need for China to reduce the growth rate of energy consumption (EC), the relationship between financial development (FD), urbanization (UR), and EC is directly related to the effectiveness of China's current ecological civilization construction. This study analyzes the internal relationship between the three from the perspectives of financial scale (FD1), financial structure (FD2), and financial efficiency (FD3) through the generalized method of moments (GMM) estimation, impulse response, and variance decomposition of the panel vector autoregression (PVAR) model. The following conclusions are derived. First, the results of the PVAR model show that when FD is measured with FD1, FD2, and FD3, each variable has path dependence, and the lag-phase-one term of each variable has a strengthening effect on itself. Second, based on the pulse response diagram, a positive response occurs after FD1 and FD2 give a standardized shock to EC, but a negative response occurs when FD is characterized by FD3. When FD is measured with FD1, a positive response occurs after UR gives a normalized shock to EC. When FD is measured with FD2 and FD3, there is a weak negative response. Third, the results of the variance decomposition show that the changes of FD, UR, and EC rely more on their own inertia. Although the impact of FD and UR on EC has an increasing trend, the impact is small. Therefore, local governments should rationally control the financial scale, optimize the financial structure, improve the financial efficiency, and strengthen the propaganda of energy conservation.

      Authors: Yuanzhi Xiao, Ruiqi Sun, Ke Gao
      Abstract: Energy & Environment, Ahead of Print.
      As a result of emerging climate change trends, businesses and organizations are becoming more concerned about environmental sustainability. In this context, green supply chain management (GSCM) approaches are expanding globally. Based on institutional and sociotechnical systems theory, the conceptual model of this research highlights a mediation of two GSCM types, namely technological and behavioral practices, as well as the moderation of organizational pressure on institutional performance. The hypotheses were evaluated using the structural equation modeling (SEM) method, obtaining data from 563 Chinese firms. This study's categorization of technological and behavioral GSCM practices and results add to the literature on GSCM. The empirical findings indicate that the technological GSCM practices considerably affect behavioral practices. Moreover, GSCM technological and behavioral practices have a substantial effect on institutional performance. GSCM behavioral practices mediate the link between technological GSCM practices and institutional performance. The outcomes also reveal that organizational pressure moderates the association between GSCM technological GSCM practices and institutional performance. These results show that companies in emerging economies should prioritize the behavioral GSCM practices to successfully apply the technological GSCM practices to achieve compelling financial, social, and environmental performance.

      Authors: Sakib Bin Amin, Farhad Taghizadeh-Hesary, Foqoruddin Al Kabir, Farhan Khan
      Abstract: Energy & Environment, Ahead of Print.
      The incremental capital-output ratio indicates the extent of capital efficiency as firms gradually become technically efficient. Therefore, we aim to empirically assess the linkage between energy intensity and incremental capital-output ratio from a holistic point of view, the first of its kind, by analyzing data from select South Asian countries, lower- and middle-income, and high-income countries. We use standard and robust cross-sectional augmented econometric methodologies for the empirical analysis using data from 1990 to 2018. We reveal unidirectional causation from the incremental capital-output ratio to energy intensity in five South Asian countries and 52 high-income countries. However, bidirectional causality is found between the incremental capital-output ratio and energy intensity for the 34 lower- and middle-income countries. The elasticity of the incremental capital-output ratio to energy intensity for South Asian countries is 0.15 in the long-run. By contrast, the same elasticities for lower- and middle-income and high-income countries are 0.11 and 0.003, respectively. The effect of the incremental capital-output ratio on energy intensity is significantly lower in high-income countries than in the other two groups due to technical inefficiency. Our results are expected to guide the policymakers in developing and emerging economies in adopting optimal policies to achieve efficient and sustainable production and consumption.

      Abstract: Energy & Environment, Ahead of Print.
      Nuclear energy has sparked international attention as one of the most important strategies for reducing emissions thanks to its ability to provide low-carbon power. Based on this interesting fact, the current research explores the effect of nuclear energy on CO2 emissions in the leading countries by nuclear power consumption using a quarterly dataset from 1990 to 2019. The study employs the quantile-on-quantile (QQ) estimator, which accounts for both non-parametric and conventional analyses and enhances the provision of unbiased and consistent estimates. In addition, the Granger causality in quantiles approach is adopted to assess the causality in quantiles between the variables of investigation. The outcomes from the QQ estimator reveals that in the majority of the quantiles, nuclear energy contributes to decreased degradation of the environment in the USA, France, Russia, South Korea, Canada, Ukraine, Germany, and Sweden. Contrawise, the feedbacks from Spain and China expose that Nuclear Energy Consumption (NUC) contributes to the deterioration of the environment. Moreover, the outcomes of the causality test disclose that nuclear energy and CO2 emissions can predict each other in the majority of the quantiles. The findings above provide profound ramifications for policymakers planning nuclear energy and CO2-emission policies towards achieving sustainable environment in the sample countries and beyond..

      Abstract: Energy & Environment, Ahead of Print.
      Increased urban air temperature considerably affects the health, comfort and consequently the quality of life in urban spaces. Urban design and planning studies, therefore, face an increasing challenge as they aim to improve Outdoor Thermal Comfort (OTC) and microclimate conditions of urban environments. Analysing OTC is more challenging when compared to indoor thermal comfort since a wider range of interrelated parameters exists in outdoor environments. Therefore, this research aims to classify urban studies that investigate OTC by conducting a comprehensive review based on key metrics such as approaches taken, methodologies and spatial and temporal scales. By extracting the key findings, this research forms an integrated framework of these metrics that presents a thorough view of the OTC concept in the context of climate-sensitive studies. Furthermore, this research elaborates on the main two groups of parameters affecting OTC including environmental and human-based parameters. Exploring the intricate inter-relationships of these two groups of parameters clarifies their contribution to OTC. Results of this study help architects and urban planners to improve their climate-sensitive strategies and support the decision-making process by providing a comprehensive perspective about different aspects of OTC. Finally, recommendations for future research are outlined.

      Authors: Ryo Kohsaka, Satomi Kohyama
      Abstract: Energy & Environment, Ahead of Print.
      There has been an increasing effort to promote renewable energies as climate change mitigation measures in Japan. Yet, the installation of wind turbines and solar photovoltaic (PV) power plants is being contested in several parts of the country. There is a need to understand these oppositions to reduce the number of delayed projects or overcome future barriers. Thus, in this study, we investigated cases of opposition movements and legal proceedings against wind and solar PV power development. Results indicated that landscape elements and socio-ecological factors motivate local oppositions. For instance, there were cases filed due to landscape view obstruction caused by wind turbines and solar panels. In terms of socio-ecological barriers, examples of cases scrutinized showed opposition caused by the potential impact on recreational activities such as climbing and hiking trails. Additionally, we observed that there were differences in the scope and scale of opposition movements and legal proceedings between wind and solar PV power projects. These differences were related to the scale (project size) and duration (construction to operation) of the project coupled with the renewable energy-related legal system changes in Japan. We observed that the overall legislative framework is frequently designed at the national level while challenges in project site selection are dealt with at the municipal- and prefectural-level. The findings of this study can help policymakers to revise and/or develop legal systems that minimize impacts on landscape and social elements while satisfying the demand for renewable energy transitions.

      Abstract: Energy & Environment, Ahead of Print.
      By developing the mathematical model of a serial multi-stage reverse electrodialysis reactor (REDR) system for wastewater treatment, this paper numerically simulates the degradation process of azo dye (methyl orange) dyeing wastewater. The operation performances of the serial system with an anode and cathode synergetic degradative circulation mode are explored by numerical simulation. The influences of operation parameter variations on key performance indicators are investigated and discussed. Results indicate that the serial system can achieve excellent electricity conversion efficiency and degradative performance under an appropriate output current condition. A high initial MO concentration and electrode rinse solution (ERS) flowrate are helpful to improve the treatment performance of the system. A low concentrated solution (CS) concentration is beneficial for raising the electricity conversion efficiency and reducing the total energy consumption (TEC).

      Abstract: Energy & Environment, Ahead of Print.
      Addressing the challenges posed by pollutants is necessary to achieve the Sustainable Development Goals (SDGs) target 12 or achieve sustainable production and consumption patterns. Convergence assessment of air pollution provides information which can be beneficial to how to handle that air pollution across different countries. Nitrogen oxides (NOx) are one of the most popular air pollutants. However, the current empirical literature on environmental economics largely ignores the convergence of per capita NOx. For this reason, this study investigates the stochastic convergence of aggregate and fuel-specific per capita NOx emissions in 20 OECD countries. This paper employs a recently introduced panel stationarity test that considers both smooth and sharp structural changes in the data generation process. The panel results show that the convergence hypothesis is rejected only for NOx from light-oil consumption. However, country-specific results reveal substantial evidence for divergence in the sample countries when NOx emissions per capita generated through diesel consumption, light-oil consumption, and natural gas consumption are considered. Besides, we find that most of the series have convergent behaviour for aggregate NOx, NOx from biomass consumption, NOx from hard-coal consumption, NOx from heavy-oil consumption, and NOx from the process. The policy implications of the empirical results for proper environmental management are elucidated in the paper. Actions taken based on the convergence findings will likely lead to a decrease in NOx emissions per capita as the countries will converge towards a lower level of NOx emissions per capita, in line with SDG's target 12.

      Abstract: Energy & Environment, Ahead of Print.
      As a new approach, biodegradable solid polymer blend polymer electrolytes are prepared using a synthetic polymer Poly [vinyl pyrrolidone] (PVP) and a biopolymer Starch with constant amount of Ammonium ceric nitrate. The Biopolymer starch is used to enhance the biodegradability of the polymer membranes. The polymer electrolytes are prepared by solution casting method using deionized water as solvent. The prepared electrolytes are analyzed with structural, vibrational, electrical and electrochemical behavior by using different characterization techniques. The amorphous nature of the blend polymer electrolytes has been confirmed by X-Ray diffraction (XRD) analysis. PVP/cassava starch/ammonium ceric nitrate polymer electrolyte shows high amorphous nature. In FTIR study, polymers-salt complexation and molecular vibrations are observed in the electrolytes. The ionic conductivity and dielectric measurement of the electrolytes are carried out by impedance spectroscopy. The maximum ionic conductivity of 8.1 × 10−6 S/cm is observed at room temperature for 80% PVP: 20% cassava starch: 2% ammonium ceric nitrate (ACN) system. The dielectric properties of the prepared polymer electrolytes are also analyzed. The electrolyte having higher ionic conductivity is tested with cyclic voltammetry (CV) and linear sweep voltammetry (LSV) studies that reveal the electrochemical properties and range of potential window of the polymer electrolyte.

      Abstract: Energy & Environment, Ahead of Print.
      Aiming to net-zero emissions, hybrid power generation through renewable means has gained substantial attention across the globe. Considering the stochastic nature of renewable energy resources, a comprehensive performance assessment is a must prior to project development. Present work is a novel multidimensional 6E analysis (energy, exergy, economic, environmental, advanced exergy, and exergoeconomic) to evaluate the performance of hybrid wind-solar energy systems. The analysis is performed using long-tern (41 years) high-resolution ERA5 reanalysis resource data and the mathematical modeling by means of MATLAB R2018a computation software. The long-term data facilitates reliable and precise predictions of resource availability, power generation, and system performance during the lifespan of the project. The performance of HWSES in terms of capacity factor and exergy efficiency is computed to be 9.6–35.5% and 4.7–10.4% respectively, whereas the extended exergy efficiency lies in the range of 3.39–5.79%. Hybridizing wind power projects with solar power enhances the overall system capacity factor, exergy efficiency, and extended exergy efficiency by 3.46%, 5.12%, and 2.87% respectively. Hence, the hybridization leads to superior year-round system performance with smaller power fluctuations than the standalone systems. Further, wind, solar and hybrid systems would annually reduce the Specific Emission Reduction of 1128 tone/kW, 1685 tone/kW, and 1407tone/kW respectively. The present research will be helpful to the policy-makers and the project developers in the project feasibility study of hybrid energy systems.

      Authors: Chaima Ghanjati, Slim Tnani
      Abstract: Energy & Environment, Ahead of Print.
      In this paper, a genetic algorithm is applied to optimize the sizing of an autonomous renewable energy multi-source system for reliable and economical supply of energy. The multi-source system is composed of a photovoltaic generator, a pumped storage hydropower system and a battery. The system will power public lighting and operate a garden fountain in the Botanical Garden, located in the Alexandre Aibéo Park in Covilhã (Portugal). Solar irradiance is initially simulated for a reference photovoltaic capacity (25 kWp) over one year by the PVsyst software for the city of Covilhã. Two objective functions are used for sizing optimization: the loss of power supply probability (LPSP) and the levelized cost of energy (LCE). The LCE takes into account the capital cost, the replacement cost and the cost of operation and maintenance. The genetic algorithm is used to determine the best configuration of the different subsystems (photovoltaic generator capacity, upper water reservoir capacity and battery capacity). The originality of this work lies in the combination of two storage elements with different dynamics, the introduction of an adapted energy management strategy (EMS) allowing to manage energy flows between the different subsystems and to control the process of charging/ discharging storage elements, and multi-objective optimization (considering technical and economic criteria) of the sizing of the autonomous photovoltaic/pumped storage hydropower/ battery hybrid system using genetic algorithm.

      Abstract: Energy & Environment, Ahead of Print.
      Even though social innovations activities have been garnering global interest, their implications on energy transition remain unclear. In this study, we aimed to define social innovation activities that can support energy transition. We interviewed 19 social innovation agents, and the grounded theory (GT) method was applied to define the social innovation activities applicable for energy transition through inductive reasoning. Our results revealed that social innovation activities for energy transition could be defined as the entire interaction process between the pragmatic actions of agents and the participation of citizens. Notably, social innovation activities for energy transition could increase citizen participation and help economies to transition from conventional to alternative energy production and use systems. Thus, these activities lead to significant changes in the behaviors and attitudes of citizens, which are the prime factors when incorporating a subsequent structural change. Our study can provide a reliable framework to understand social innovation activities for energy transition and guide both agents and policy practitioners in decision-making, to improve and smoothen energy transition in South Korea.

      Rapid industrialization and population expansion increased the demand for petroleum-based fuels, resulting in price hike and creates serious environmental issues. Biodiesel, a clean, renewable and long-lasting alternative and for large scale production needs readily available and sustainable feedstocks. Edible and non-edible plants are abundant in Southern India, particularly Ceiba penandra (CP), Mahua longifolia (ML), and Azadirachta indica (AI), which were employed in this study in combination. An efficient heterogeneous nano-catalyst CaO-TiO2 was synthesized and employed in the transesterification process due to its recoverability and insensitivity to FFA. The catalyst was subjected to characterize by FTIR, XRD and SEM with EDX mapping. Response surface approach is engaged in this study for cost-effective production. More than 95% biodiesel yield was achieved for Ceiba penandra oil (CPO), Mahua longifolia oil (MLO), Azadirachta indica oil (AIO) and their mixture (MIO) by optimization of significant reaction parameters and the best combination was obtained as methanol oil ratio (0.32, 0.46, 0.34 and 0.42 v/v), catalyst usage (5, 6.5, 6 and 4 wt.%), mixing intensity (750, 840, 700 and 540 rpm) and duration (80, 105, 85 and 85 min) respectively with constant temperature of 70°C. Fatty acid profile was characterized by chromatograph also established the properties by ASTM and EN guidelines to confirm its compatibility in the IC engine.

      Rapid modernization and industrialization have significantly intensified carbon emissions and worsened environmental sustainability around the globe. Despite the significant importance of green innovation, clean energy consumption, and education in every aspect of life, the role of all these variables in determining environmental sustainability has not been explored quite extensively in case of China. Under this premise, the present study aims to investigate the role of green innovation, clean energy investment, and education on environmental sustainability in highly polluted Asian economies for the period of 1991–2019 by employing the autoregressive distributed lag (ARDL) model. The findings infer that increase in green innovation reduces CO2 emissions in China, India, and Japan in the long-run. However, an increase in clean energy investment and education tends to decline CO2 emissions in Russia and Japan. The findings confirm that green innovation, clean energy investment, and education improve environmental sustainability in long-run, while short-run estimates are diverse. Thus, governments of highly polluted economies should increase investment in education, clean energy, and technology to mitigate CO2 emissions.

      Abstract: Energy & Environment, Ahead of Print.
      China’s outward foreign direct investment (OFDI) provides a window of opportunity for the Belt and Road (B&R) countries to solve their transportation challenges and achieve green economic growth. This study examines the causal relationship between China’s OFDI, transport, and green economic growth in 63 B&R countries from 2005 to 2019 using system GMM estimators. The empirical results indicate that there is a multifarious relationship between these factors. China’s OFDI can effectively facilitate the transport infrastructure construction of host countries, which will spur green economic growth. Moreover, the B&R countries with transport and green economic growth gap are more likely to contribute to China’s OFDI “attractiveness.” These conclusions provide a policy basis for the B&R countries to attract China’s OFDI, develop adequate transportation infrastructure, and enhance sustainable green economic growth.

      Authors: R. Maniarsu
      Abstract: Energy & Environment, Ahead of Print.
      Over the past century, the concentration of carbon dioxide (CO2) has significantly increased in our atmosphere, creating numerous catastrophic effects and environmental impacts. There are three main CO2 capture methods: (a) post-combustion, (b) pre-combustion, and (c) oxy-fuel combustion implemented to capture CO2 from significant CO2 emitting sources. Further, the captured CO2 is utilized to convert it into value-added products. The current status of potential combined CO2 capture and CO2 utilization methods provide the solution to the issues of greenhouse-gas CO2 emissions from anthropogenic activities and the ever-growing energy demand challenges. These unique approaches dramatically reduce the overall energy penalty, cost-effective, and have a low environmental impact. As of now, carbon management is more intensively shifting toward the carbon utilization for minimizing energy consumption and replacing fossil fuel with the cleaner energy sources. This paper presents an idea of co-integration pathways for CO2 capture and CO2 utilization.

      Authors: Mortaza Baky Haskuee, Ali Asgary
      Abstract: Energy & Environment, Ahead of Print.
      During Covid-19 pandemic world economy experienced negative growth rate, therefore energy consumption and consequently emission pollution decreased. According to Environmental Kuznets Curve, it is expected that energy consumption and emission pollution increase in response to Covid-19 economic recovery, even higher than its pre-pandemic level. The goal of this paper is to study the environmental risk of Covid-19 economic recovery. We use an Environmentally-Augmented Global Vector Autoregressive Model (E-GVAR) to trace dynamic effects of Covid-19 economic recovery on pollution emission. Using generalized impulse response functions (GIRFs), we investigated the effect of positive economic shocks in real per capita income in China and USA economies on total [math] equivalent emission pollution. The results show that positive economic recovery affects emission pollution significantly. China and emerging economies may experience high risk while Europe region is moderately affected by this positive shock. A positive Economic Shock in China decrease pollution emission in USA over time. It can be attributed to substitution effect of Chinese product in global market. Generally, our results demonstrate spillover effect of transition shocks from large economies to the rest of world and highlights the importance of linkages in the world economy.

      Abstract: Energy & Environment, Ahead of Print.
      To compensate the oil demand and pollution, scientists explore biodiesel as a pollution free alternate energy. But depending on one particular species of feedstock will lead to its extinction like diesel. For this intent, this research proposes a novelty on blending of binary non-edible high oil yielding species. As biodiesel is a natural constituent with elevated oxygen content, a stability analysis has to be performed to diminish its rapid decay. For stabilizing fuel properties synthetic antioxidants have been involved as inhibitors. Previous studies have been performed on the stability analysis individually as oxidation, thermal and storage stability without analyzing them mutually. This research fills the key gap by deeper mutual stability analysis, as the output parameters of these three stabilities are interrelated. Few samples have shown best stability output parameters which challenges in narrowing the best blend. To face this task, a multi objective optimization study has been done. NOx emission has been reduced with the aid of antioxidants as a twin reward. Two novel assessment tools for validating are, i) FTIR, by which the impact of molecular arrangements on stability variation has been evaluated and ii) Using Infrared Imaging Technique, by which the NOX has been analyzed visually correlating the emission level and engine combustion temperature.

      Authors: Muhammed Sehid Gorus, Erdal Tanas Karagol
      Abstract: Energy & Environment, Ahead of Print.
      For a few decades, factors affecting environmental deterioration have been at the center of much interest This paper examines the impact of income level, disaggregated energy consumption, types of globalization level, and urbanization on per capita ecological footprint by utilizing novel machine learning techniques (tree regression, boosting, bagging, and random forest) for 27 OECD countries during 1971–2016. It is found that the random forest algorithms best fit the dataset. The empirical results exhibit that oil product consumption, electricity consumption, and gross domestic product are the most significant variables for our model. Besides, the partial dependence plots results show that economic growth and especially fossil fuel energy consumption damage the environment. These findings have important implications for both developed and developing countries for designing proper energy and environmental policies. Especially, policymakers should focus on sustainable development instead of plain economic growth.

      Authors: Ngo Thai Hung
      Abstract: Energy & Environment, Ahead of Print.
      In connection with environmental degradation in Vietnam, known as an emerging economy, very limited studies have been implemented to demonstrate the environmental aspects of the country's core policies, as well as recent economic policies such as economic growth and globalization policies. Given this driving force, this paper uncovers a novel perspective on the causal associations between CO2 emissions, economic growth, and globalization in Vietnam using wavelet analysis. The empirical results provide evidence of the interconnections between the selected indicators through time and frequency. More accurately, the findings uncover that economic growth and globalization significantly increase carbon dioxide emissions in Vietnam in the medium and long run. These outcomes highlight the importance of policymakers properly coordinating policies to address Vietnam's severe environmental degradation. Furthermore, Vietnam should continue relevant policy reforms such as encouraging investment, allowing for effective governance and promoting human capital accumulation.

      Abstract: Energy & Environment, Ahead of Print.
      Achieving ecological sustainability is a critical issue of the current era, and researchers are striving to find viable solutions for sustainable development and ecological wellbeing. This study is an effort to examine the ecological consequences of renewable energy (REC), financial development (FD), and technical efficiency (TE) in 27 countries of the European Union (EU), time ranges from 1980 to 2018. We used second-generation econometric techniques to consider the cross-sectional dependency in the model and the CS-ARDL method to estimate the long-run dynamics of the variables. The Westerlund cointegration technique confirmed the long-run association among REC, FD, TE, and ecological footprint (EF). Furthermore, CS-ARDL results revealed a positive influence of FD on EF, indicating FD is a significant contributor to the ecological footprint of the EU. However, REC and TE promote ecological sustainability in the EU, as both factors negatively affect the EF. Furthermore, the interaction of FD and TE is also estimated to mitigate EF in sample countries. The study recommends that government policies in EU countries must be skewed towards promoting renewable energy usage, lending in green and energy-efficient technology, and technological advancement in the production process.

  • Creating a decarbonized economy: Decoupling effects and driving factors of

      Abstract: Energy & Environment, Ahead of Print.
      Identifying the carbon emission characteristics, driving factors, and decoupling status of the industrial subsectors is important for developing effective policy measures. This allows for implementing industrial emission reduction that, eventually, decouple carbon emission and economic growth. Such an analysis is especially important for the case of China on its way towards sustainable development and increasing global interrelationships. However, the literature still lacks comprehensive analysis, especially, at the industry level. This study uses the Logarithmic Mean Divisia Index and decoupling indicator to analyze how different factors contribute to CO2 emissions in 28 industries in China during 2002–2017. The results reveal that the growth of industrial CO2 emissions has been positive but decreasing. The highest CO2 emission change is observed for production and supply of electric and heat power, processing of petroleum, coking, and nuclear fuel, and smelting and pressing of metals. These sectors also show high carbon intensity levels. The economic output (scale) effect and population effect comprise the two major factors promoting the CO2 emission. The energy intensity effect is the key inhibiting factor of the industrial energy-related CO2 emission in China. The suppressive effects of energy and industrial structure have been continuously increasing. The economic growth and CO2 emission has been gradually decoupling in the case of the 28 sectors analyzed. Manufacture of cloths, leather, fur, feather, and related products as well as production and supply of gas exhibit a relatively stable strong decoupling. Based on the decoupling analysis, this study shows that energy intensity has induced the decoupling, whereas the opposite effect has occurred due to economic growth, and the other factors showed little effect on CO2 emission decoupling.

      Abstract: Energy & Environment, Ahead of Print.
      Under neoclassical assumptions, this paper develops a model to illustrate the effects of government use of carbon allowances for carbon emission control. We find that control using the instrument of issuing long-term carbon allowances does not produce the same good results in the Decentralised Equilibrium as in the Planning Problem. Thus, while Coase's Theorem ensures that the Pareto optimum is maintained in an economy with multiple agents, it does not align the social development with the economic optimum of the planner. We believe this is due to the that the price of carbon allowances is determined by asset profiles of investors rather than externalities. The steady-state under the special pathway shows that consumption is determined by the rate of technological progress, the total amount of carbon dioxide at steady-state, the level of technology at which steady-state is reached and the total amount of carbon allowances remaining. The comparison with the optimal tax path reveals that the price of carbon allowances has increased too quickly, leading to excessive consumption of fossil fuels in the early stages.

  • Can raising trade barriers curb industrial pollution emissions'

      Authors: Shuhong Wang, Yuqing He, Hanxue Chen
      Abstract: Energy & Environment, Ahead of Print.
      The development of foreign trade and industrial pollution control is an important theme of government governance today. Based on the institutional background of rising international trade protectionism, this study examines the impact of trade barriers on industrial pollution emissions by using different measurement methods and data from 16 industrial sectors in 10 major countries. The results show that lowering trade barriers can significantly reduce industrial pollution emissions, considering the impact of potential endogenous problems. Heterogeneity analysis shows that reducing trade barriers in developed countries can reduce industrial SO2-emission intensity, while the opposite is true in developing countries. Trade barriers have the greatest effect on the pollution-emission intensity of technology-intensive industries, followed by labor-intensive and capital-intensive industries. Mechanism analysis shows that trade barriers affect industrial pollution-emission intensity through both pollution emission and industrial output and that energy-use intensity and biased technological progress are important mechanisms. This study provides a useful reference for governments to promote foreign trade development and ecological and environmental protection.

      Nowadays, with the growing demand for energy and effective utilization of various available sources with the exorable techniques and approaches to maximize the efficiency of energy systems. This work has developed the synthesis of Methyl chloride (MC) from the methane chlorination process using the ASPEN HYSYS simulation tool. A Searchable analysis has been done on thermodynamic derivatives (likely Energy, Exergy) to probation on the entire process. This analysis calculates all process components’ energy loss, destruction and energy, and exergy efficiencies. A heavier energy loss has been found at Reactor (ERV) with 1785.5 kW and exergy destruction of 18.8% share. Heat Exchanger Network (HEN) has energy loss (960.32kW) & exergy destruction (791.29kW). The proposed new retrofit sustainable model recovered the waste heat from the HEN and achieved energy efficiency of 87.6% and exergy efficiency of 87.3% of the total MC process. Four Machine learning models were developed for the reactor (ERV) process to predict exergy destruction. The artificial Neural network (ANN) gave good testing predictions, followed by the Random Forest (RF) with a determination coefficient (R2) of 0.999957 and 0.999981.

      Incorporating TiO2 with CNTs and PAN nanofiber structures results in a photocatalytic membrane composite with an attractive response in the visible region. It offers an efficient process without post-treatment separation at the end of the photocatalytic treatment. The composite membranes were fabricated using electrospinning at 7 kV with 10 cm in the distance between needle tip and collector at a flow rate of 1 mL h−1. Polyacrylonitrile (PAN) was used as the polymer matrix. All the as-spun composites exhibited randomly oriented nanofibers. CNT increased the fiber diameters from 324 to 463 nm. The bandgap of TiO2 also shifted from 3.15 to 2.76 eV at the narrowest The color removal kinetics follow the Langmuir-Hinshelwood pseudo-first-order kinetics model with the highest rate constant of 0.0225 min−1 shown by PAN/TiO2/CNT 20%. More than 95% color removal of methylene blue after 100 min irradiation has been achieved using LED lamps of low energy visible light (43.5 W). Such a result is supposed to be the highest employing low energy lamps.

      Abstract: Energy & Environment, Ahead of Print.
      Pig waste can be used to generate energy through biogas and has been gaining importance for being a renewable energy source. The resulting biogas can be used in many forms, such as to produce electricity and supply local networks using microgrids. This helps bring greater stability and energy security to local electricity supply networks. Under this light, this article aims to (i) report on socio-environmental impacts, (ii) present lessons learned (from a circular economy and territorial intelligence perspective), and (iii) point out future business opportunities of value recovery from waste in rural properties. To that end, a case study was carried out in a rural property in Paraná, Brazil. The authors conducted local visits and surveys, and consulted documents provided by the property owners about projects making use of biogas produced from pig waste and used to generate electricity. Different partnerships between the property and public and private bodies enable business opportunities arising from projects that range from the commercialization of carbon credits, decentralized energy generation, to sale of energy to the State's energy provider and establishing Microgrids. From those projects, direct and indirect environmental and social benefits are primarily related to the replacement of non-renewable energy with renewable energy from waste, and impacts avoided from the inadequate handling of pig waste. The results show that it is possible to explore the energy potential of rural properties, based on livestock waste, by developing partnerships with public and private actors, producing energy from biogas, from circular economy and territorial intelligence perspectives.

      Abstract: Energy & Environment, Ahead of Print.
      Industrial sludge must be disposed of by incineration or storage methods. It is possible to produce energy by incinerating the sludge after drying. However, some sludges cannot be incinerated due to their low calorific value and/or high pollutant load. In this study, a novel process in which sludges with high calorific value and other sludges are mixed, dried and processed to produce solid fuel without using any additives is described. A technical and economic model of the process was established and feasibility analysis was carried out for different capacities. According to the results of the study, with the increase in capacity, the cost for the unit capacity and the return for the unit capacity increase. Most of the plant's income comes from waste disposal. When the investment is made with equity, the payback period is shorter than 2 years for wet feeding capacities of 1 ton/h and above. The cost of the investment increases more than 2 times when 50% of the investment cost is supplied by a bank loan. In this case, the payback period is also increasing. In order for the profitability of the facility to be sustainable, the composition and amounts of sludge produced in the region should be analysed. In this study, it is assumed that the types and amounts of waste that will come to the facility are capable of filling the facility's capacity and providing the required calorific value standards.

      Abstract: Energy & Environment, Ahead of Print.
      The decoupling of carbon emissions has also become the dependence of countries’ development. Finance plays an important role in decoupling economic development from carbon emissions. This paper explores the impact of financial development in different regions on the decoupling of carbon emissions from economic growth, using the Tapio decoupling elastic model and the method of fully modified least squares (FMOLS) to study the impact of financial development on carbon emissions in six regional panels from 1995 to 2020: and Foreign direct investment (FDI), urbanization, population, and infrastructure as control variables. The results turn out that financial development will promote the decoupling of carbon emissions from economic growth in the ECA region. For EAP, SSA, AC, SA, and MENA regions, financial development will promote the growth of carbon emissions, and due to the different economic development dynamics of different countries, the positive effects of financial development on carbon emissions are heterogeneous. The impact of FDI, urbanization, and infrastructure on carbon emissions varies from region to region. The population will promote the growth of carbon emissions, regardless of the region. In addition, the ECA region is the most countries that has achieved the strong decoupling and is the first to realize the transition from weak decoupling to strong decoupling. Therefore,the ECA, EAP and AC region should accelerate the construction of a green financial system to promote the decoupling of economic growth and carbon emissions. The SSA, SA and MENA region should speed up the transformation of economic development mode and move towards weak decoupling or even strong decoupling.

      Solar power plays a significant role in the contribution of energy worldwide. The performance of solar panels mainly depends upon geographical and environmental factors. Dust is an important well known ecological factor that significantly impacts the performance of solar panels in achieving the overall target of power production by renewable sources. Study about the performance of solar panels under the influence of dust particles becomes more effective when these are to be worked out in hot and dusty areas. The current goal of this review article is to provide the impact of dust particles on the performance of solar panels. To fulfil this goal, the researcher's contribution is updated in minor for 2015 to 2018 and signed for 2019 and 2020.The current authors of this review article also recommended the adoption of a modern cleaning technique for PV modules, which would save time because it could be operated away from the PV modules.

      Abstract: Energy & Environment, Ahead of Print.
      One of the secrets for China's economic growth miracle is continuous investment in infrastructure, and the role of power infrastructure is irreplaceable. However, previous studies mostly focused on generation-side indicators rather than grid-side indicators, ignoring the importance of the mega-grid established in China. As a result, this paper is committed to exploring the economic growth pulling effect of power grids with different voltage levels in the nonlinear framework. On the premise of determining the robustness of estimation parameters by instrumental variable method, the panel smooth transition regression (PSTR) model is used to capture panel heterogeneity. To be exact, the regional economic growth driven by extra-high voltage (EHV) and ultra-high voltage (UHV) power grids presents a regime transition accompanied by the growth of regional power generation and electricity consumption per capita. This means that the mega-grid is more conducive to the economic growth of energy bases and load centers. To further build and improve the state-leveled mega-grid into a nationwide basic platform for trans-regional renewable energy transmission and distribution is a key measure to enhance China's sustainable economic growth under the constraints of carbon peak and carbon neutrality targets.

      Abstract: Energy & Environment, Ahead of Print.
      The performance of solar photovoltaic systems tends to decline if the operating conditions change from the nominal operating cell temperature due to environmental factors. The major factors include temperature and humidity variations, which cause thermal losses and open-circuit voltage drops in photovoltaic panels. This study investigates the correlations between solar photovoltaic performance and environmental factors by quantifying the real-time variables including temperature, humidity, dewpoint temperature, and heat index. Furthermore, the study investigates the difference between real-time measured and theoretically calculated temperature values with the help of weather station data to investigate the impact of temperature difference on the overall percentage power loss of the systems. The panels were installed at three distinct sites (rooftop, parking shed, and ground-mounted) connected to the same grid-tied system. Results reveal that the photovoltaic panel temperature has an inverse relation with the dew temperature and the humidity of the surrounding environment. The heat index value was found slightly less at the peak solar hours during the 24 h cycle of the measurement. The difference and relationship between temperature and humidity are measured and losses are highlighted based on the instantaneous occurrence of variables. Based on a difference between measured and calculated temperature values, results reveal that PV systems faced 27.95%, 5.41%, and 0.82% power losses for ground, roof, and parking installed PV systems, respectively.

      Green growth is recognized as an adequate mechanism to decelerate environmental turmoil. However, empirical evidence on what determines sustainable economic growth is still underexplored. Apprehending the importance of financial liberalization, human capital, and militarization in the South Asian region, we investigate their short- and long-run effects on green growth using data from 1990 to 2017. To address the cross-sectional dependency (CD) and heterogeneity issue, second-generation cointegration estimation techniques are employed. The findings show a stable and long-run relationship between financial liberalization, human capital, military expenditures, and green growth. The results of CS-ARDL also show the positive long-run effect of financial liberalization and human capital while the negative effect of militarization on green growth. Nonetheless, the interaction effects show the darker side of human capital and the brighter side of militarization in the presence of more financial openness. Results were further validated using the Augmented Mean Group (AMG) and Dumitrescu-Hurlin Granger causality test, highlighting the need to optimally utilize military expenditures, financial liberalization, and human capital for the sustainable growth of the region.

      Abstract: Energy & Environment, Ahead of Print.
      Cement production reportedly accounts for the largest global materials flow, thus achieving global environmental sustainability through responsible consumption and production is central to the sustainable development scenario. But even that China, the world's largest carbon emitter and largest cement producer, is under-studied. Thus, the current study employed the nonlinear ARDL and frequency domain causality methods to unearth the contributory or mitigating role of energy sources and economic progress in China's cement carbon emission (CCE) over the period 1971-2020. Overall, the study establishes long-run equilibrium relationship between the study variables of interest Subsequently, the baseline regression suggests that a positive shift in economic growth, energy from fossil fuel and primary energy consumption all increase emissions while a negative shift does not have a significant effect on emissions. Moreover, a positive (negative) shift in renewable energy decreases (increases) emissions in both the short and long-run. The result of the Frequency Domain causality analysis resonates with the results of NARDL regression. As a policy, this study infers energy development and economic-related measures are strategically important in achieving sustainable cement production and consumption.

      Authors: Farrukh Shahzad, Zeeshan Fareed, Yong Wan, Yihan Wang, Zohaib Zahid, Muhammad Irfan
      Abstract: Energy & Environment, Ahead of Print.
      This study corroborates the asymmetric and heterogeneous associations between clean energy intensity (CEI) and carbon dioxide (CO2) emissions among the world's top ten renewable energy consumer countries using quarterly data from 1970Q1 to 2018Q4. We quantify the complete dependence structure between CEI and CO2 at quantile distributions using a novel quantile-on-quantile (QQ) method proposed by Sim and Zhou (2015). Compared to classic approaches such as quantile regression and ordinary least squares, the QQ technique can provide more information on the overall relationship between CEI and CO2. Furthermore, we also seek to determine causal relationships between CEI and CO2 using a quantile Granger causality approach suggested by Troster. According to our empirical evidence, the link between the two variables is predominantly negative. Moreover, there are significant disparities across countries in the quantile ranges of CEI and CO2. In particular, there is a weak positive link between CEI and CO2 in the case of Sweden, Italy, Japan, and Australia, which may be because CEI has a minimal direct influence on CO2 in these countries. The empirical findings clarify that policymakers should fund renewable energy industries to minimize carbon dioxide (CO2) emissions and achieve Sustainable Development Goals (SDGs).

      Abstract: Energy & Environment, Ahead of Print.
      This paper takes Jiangsu as an example to measure the carbon emissions from the electric power industry from 2002 to 2017, builds an extended STIRPAT model to quantify its driving factors, and uses the Monte Carlo method to simulate the evolution of carbon emissions in multiple scenarios from 2018 to 2030. The results show that: (1)Population scale, urbanization level, GDP per capita, industrial added value, and electricity consumption intensity promote the increase of carbon emissions in the electric power industry. (2)Trade openness and the transmission level of other provinces play a role in reducing carbon emissions. (3)Under the baseline scenario and the green development scenario, the carbon emissions of the electric power industry have shown a continuous growth trend, but the growth rate of carbon emissions has slowed down significantly under the green development scenario.

      Authors: Radosław Ślosarski
      Abstract: Energy & Environment, Ahead of Print.
      In this paper, we analyse two phenomena. First, the relationship between greenhouse gases emission and effectiveness of the European Union energy policies and second the transition from the fossil fuels to renewable energy sources. We run two-step data analysis concerning 25 European Union member states in the period from 1990 to 2018. We use information on greenhouse gases emission, introduction of new energy policies, source of energy supplied and merge it with macroeconomic data on the countries’ structural characteristics. We assess their long-run relationship and direction of causality using panel cointegration tests and dynamic panel data models. We identify a statistically significant effect of energy supply source, energy policy introduction and greenhouse gases emission. However, we were not able to confirm that European Union energy sector is in transition. Thus, obtained results confirm that the EU energy policies are effective however not sufficient enough in decreasing use of fossil fuels to call it a transition towards renewables.

      Authors: Xinyue Zhang, Xiaopeng Guo, Xingping Zhang
      Abstract: Energy & Environment, Ahead of Print.
      China has proposed ambitious goals of carbon peak and carbon neutrality, and will pay more attention to the relationship between economic development and carbon emissions. It's significant to assess the current environmental decoupling and prospect the future conditions in China. This article studies the decoupling status and influencing factors in Chinese provinces from 1996 to 2018 through Tapio decoupling index and decomposition model. The results show that most provinces are currently in a weak decoupling state. The growth of per capita GDP and population will affect the process of strong decoupling, while the optimization of energy intensity, energy structure and industrial structure will promote the realization of strong decoupling. Moreover, this paper prospects the decoupling scenarios of Chinese provinces from 2019 to 2035 and finds that all provinces will achieve strong decoupling before 2040, 2035 and 2030 under different carbon emissions scenarios respectively. To achieve the strong decoupling of economic output and carbon emissions as soon as possible, the government must improve energy efficiency, use renewable energy in large quantities, and promote the industrial transformation and upgrading.

      Abstract: Energy & Environment, Ahead of Print.
      In this study, we analyzed the effect of dispersant characteristics on the selective catalytic reduction (SCR) catalyst properties and de-NOx efficiency. For this, we measured the zeta potential and pH value of each dispersant, and compared the thermal properties of the dispersant through TG-DTA analysis. Also, the Py-GC/MS analysis results and the MSDS contents of the product were used to compare the components and molecular weight types of the dispersant. As a result, the higher the zeta potential, pH, and molecular weight of the dispersant, the more improved the dispersibility of the TiO2 slurry. Characteristics such as the rheology, sedimentation, and pH change, were studied to compare the dispersibility of the catalyst slurries, and the dispersion characteristics of the TiO2 slurries were confirmed by TEM. The SCR catalysts prepared varied based on the dispersant added, with the varying factor being the de-NOx efficiency between (250 to 450) °C depending on the dispersibility. The dispersant with the excellent dispersibility gave the highest efficiency of 84% or more at 250°C and 300°C, and the highest de-NOx efficiency of more than 92% at 350°C and 400°C.

      Abstract: Energy & Environment, Ahead of Print.
      Ni2+- and Zn2+-contaminated groundwater in the coastal regions is a serious threat to water security in industrial areas. Apatite-like material is an excellent sorbent for heavy metals; however the effect of salinity on the Ni2+ and Zn2+ adsorption onto fishbone and synthesized hydroxyapatite (HAP) has not been investigated. This study investigates the effect of salinity on the single and binary adsorption of Ni2+ and Zn2+ onto apatite-like materials. The experiments were conducted in batch reactor for 24 h at 1:40 solid-to-liquid ratios (wt/wt), 25°C, and pH 5. Freundlich, Langmuir, and Dubinin–Radushkevich models fit well with the single-adsorption data. The adsorption isotherms were nonlinear (NF = 0.350–0.710). The maximum adsorption capacities (qmL) of the Ni2+ and Zn2+ onto HAP were higher than those onto the fishbone, attributed to the higher Brunauer–Emmett–Teller surface area (ABET) and cation exchange capacity. In the binary adsorption, adsorption capacities of the adsorbents were less than those in the single-solute system due to the competition between Ni2+ and Zn2+. Salinity affected the single and binary adsorption by decreasing the adsorption capacities of the adsorbents. In a binary adsorption system, the selectivity of Zn2+ was less than that of Ni2+ for both fishbone and HAP at 0‰ and 30‰ salinity, respectively. Binary adsorption models, such as the Murali–Aylmore (M–A) model, competitive Langmuir model (CLM), P-factor model, and ideal-adsorbed solution theory coupled with the Freundlich (IAST-Freundlich) model were used; of these, the M–A model provided the best prediction for the binary system.

      Authors: Lianghu Wang, Jun Shao
      Abstract: Energy & Environment, Ahead of Print.
      The rapid growth of foreign direct investment (FDI) has had a significant impact on rapid economic development and environmental pollution in China. Nonetheless, the underlying mechanism and empirical evidence of FDI impact on carbon emission efficiency have not been systematically explored. Therefore, this study investigates the impact of FDI on carbon emission efficiency via energy intensity, as well as the moderating role of the Low-Carbon City Pilot Policy (LCCP) in the process. We found that: (1) During the study sample period, the average carbon emission efficiency tends to rise, however, there remains a gap between the optimal carbon emission efficiency; (2) FDI is one of the key factors that inhibit the improvement of carbon emission efficiency, with a non-linear relationship between them; (3) FDI indirectly suppresses the improvement of carbon emission efficiency by promoting energy intensity. Nevertheless, the implementation of LCCP has a positive effect on carbon emission efficiency; (4) The implementation of LCCP has improved the negative impact of FDI on carbon emission efficiency, nonetheless, it cannot significantly influence the process that FDI affects carbon emission efficiency through energy intensity. Thus, we propose improvement measures from three aspects, i.e., increasing the introduction of foreign capital, adjusting the energy consumption structure, and expanding the scope of low-carbon cities.

      Abstract: Energy & Environment, Ahead of Print.
      In this study, we investigated the relationships between personal traits (sustainable lifestyle and consumer innovativeness), psychological and physical benefits (warm glow and government incentive), attitude toward rooftop photovoltaic (PV) system installation, and intention to install a residential PV system. Furthermore, we examined the moderating effect of solar product knowledge on the relationship between attitude and intention to install a residential PV system. Convenience sampling was performed to collect data in this study. An anonymous questionnaire was distributed to participants in the form of an online survey. To prevent priming effects, the research constructs were not presented in the questionnaire, and the questions were not presented in the order of the research constructs. Each questionnaire item was evaluated using a 7-point Likert scale, and 370 valid surveys were received. Confirmatory factor analysis (CFA) was employed to verify the validity of the constructs. The CFA results confirmed that the measurement scales used in this study were appropriate. The conclusions of this study are as follows. First, ecological lifestyle, consumer innovativeness, government incentive, and warm glow affect attitude toward rooftop PV system installation. Second, this attitude influences the intention of rooftop PV system installation, and consumer knowledge moderates the relationship between attitude and intention toward rooftop PV system installation. This study's findings provide a comprehensive theoretical and empirical basis for understanding the antecedents of attitude toward the installation of residential solar energy systems. Thus, the public sector can use the aforementioned findings as a basis for developing a residential solar energy promotion policy, and relevant public and private companies can use these findings as a basis to create attractive marketing strategies for residential solar energy technology.

      Abstract: Energy & Environment, Ahead of Print.
      Using panel data from 30 provinces in China from 1995 to 2017, this study explores the impact of natural resource rent, transportation infrastructure, innovation, financial development, green investment and energy investment on carbon emission and its role in achieving the sustainable development goals. In order to obtain long-term and short-term estimates, the auto-regression distribution lag model (ARDL) is used in this study. The results confirm that natural resource rent, transportation infrastructure, innovation, energy investment and carbon emission are significantly positively correlated in long-term and short-term. Financial development and carbon emission are not significant in short term, but in the long term, financial development will contribute to the rise of carbon emissions. Green investment will increase short-run carbon emissions, whereas it really can control carbon emissions, which is different from other studies. This research proposes to improve the level of innovation and reduce carbon emission in other fields through technological innovation, increase green investment and renewable energy investment and combine with financial development to invest more funds in low carbon environmental production industries and to build an environment friendly system.

      Abstract: Energy & Environment, Ahead of Print.
      The majority of studies analyzed show a positive and statistically significant impact of renewable energy consumption on economic growth. Nevertheless, some studies suggest a limited effect, while others find no statistically significant effect. Faced with this problem, we conducted a study aimed at analyzing the impact of renewable energy consumption on economic growth in the Kingdom of Saudi Arabia for the period 1990–2020. To determine the integration properties of the variables, we utilized the sharp and smooth structural breaks unit root test developed by Shahbaz, Omay and Roubaud (SOR). We also used the bootstrap approach of testing ARDL limits to examine the cointegration between variables. Using the VECM model, we studied the causal relationship between economic growth and its determinants. The results show, in the short and long run, the existence of a bidirectional causality between renewable energy consumption and economic growth (Feedback Hypothesis). Thus, there is a bidirectional relationship between GDP and capital and also between GDP and labor, in the long run. Therefore, an important policy implication resulting from this analysis is that renewable energy can be considered as an important factor for sustainable economic development in Saudi Arabia. The findings for Saudi Arabia may also be relevant for oil exporting countries to achieve efficiency and promote the renewable energy sector beyond oil.

      Abstract: Energy & Environment, Ahead of Print.
      An investigation on enhanced surface passivation in the existing industrial process line of large area n-type silicon (Si) Passivated Emitter Rear Totally diffused (n- PERT) solar cell has been performed. The Rapid Thermal Process (RTP) optimization for 20 min is conducted in the temperature range of 500–900°C and device evaluation is carried out with respect to regularly processed n-PERT solar cell. The impact of pre-metallization annealing is studied with the support of cell parameters like shunt resistance, reverse saturation current density determined from current-voltage measurements. The enhanced surface passivation via hydrogenation from silicon nitride (SiNx) layer during annealing is established with the help of external quantum efficiency, spectral response measurements and Fourier transform infrared spectroscopy analysis. The addition of optimized annealing resulted in improvement by 550% (from 38 to 247 µs), 7.73% (from 630.7 to 678.8 mV) and 84.77% (from 223.3 to 34 cm/s) in effective minority carrier lifetime, implied open circuit voltage and surface recombination velocity respectively. Finally, RTP technique for optimized process line has been successfully incorporated in industrial high-volume batch of 140898 CZ n-type Si wafers, which predicts conceptual validation of the study in mass scale production line with an increment in average efficiency of the device by 0.35%.

      Abstract: Energy & Environment, Ahead of Print.
      This work manifests the influence of different nanoparticles on the photovoltaic-thermal (PVT) system. The hybrid PVT (hPVT) systems provide thermo-electric energy by utilizing the module heat. The module heat is recovered for controlling the cell temperature using coolant in the channel. This work examines the impact of the type and volume concentration of different nano-fluids on the cell temperature, outlet temperature, thermo-electric efficiency of hPVT collectors. Copper (Cu), titanium dioxide (TiO2), and silicon dioxide (SiO2) dispersed in pure water are considered nano-fluids in this study. The investigation reveals that the outcomes of the PVT collector with copper-water as nano-fluid are superior to the other nano-fluids considered in the study. At 0.012 kg/s mass flow rate (MFR), the thermo-electric efficiency of the hPVT collector is 1.645% and 6.239% higher than the thermo-electric efficiency of the PVT at an MFR of 0.002 kg/s. It is also observed that with a 4% vol. concentration of Cu in the base fluid, the thermo-electric efficiency is considerably better than the efficiency at 2% and base fluid.

      Abstract: Energy & Environment, Ahead of Print.
      The utilization of fossil fuels like diesel has contributed immensely to ecological challenges such as the emission of greenhouse gasses. Hence, the motivation for sourcing another energy that is renewable as well as easily accessible from relatively cheap materials. Biodiesel is a perfect replacement for petro-diesel because it is biodegradable, economically viable, and has lower toxicity. However, there are challenges associated (poor engine efficiency) with its utilization in engines. It also raises NOx emissions which necessitates frequent engine component replacement owing to clogging, and it is ineffective in cold weather. To boost efficiency, nanoparticles can be combined with biodiesel blends. Moreover, the utilization of nanoparticle additives improves the performance of engines, rate of heat transfer, fuel mixture balance, thermo-physical characteristics, as well as the reduction in exhaust emissions. Copper oxide which is a transition metal oxide aids in the heat transfer from the engine down to the exhaust thus lowering the emissions of NOx. As a result, CuO nanoparticles are thought to have a lot of potential as a diesel engine additive and therefore, this review study was conducted to deduce the various techniques for generating CuO nano-fuels, the preparation methods, as well as their physicochemical features. Furthermore, the combustion behaviour, performance, and emission characteristics of diesel engines powered by CuO nanoparticle-containing biodiesel and blends were carefully investigated.

      This paper constructs a unique dataset of clean energy and adopts static panel models and dynamic panel specifications to explore the correlation between clean energy and CO2 emissions. Furthermore, this paper employs the interaction term of pilot areas and pilot time as the proxy of emission trading policy to examine the effect of China’s emission trading pilot on clean energy. Then, this paper conducts quasi-natural experiments on CO2 emissions. Our findings show a negative correlation between CO2 emissions and clean energy. We also find that China’s emission trading pilot has a significant impact on promoting clean energy. In addition, empirical results affirm that emission trading market pilots can help decrease CO2 emissions. Finally, we put forwards relevant policy recommendations.

      Abstract: Energy & Environment, Ahead of Print.
      Biomass can be converted into energy, fuels, and value-added products by adopting proper conversion or production methods. For many years, biomass has been considered to be a good candidate for producing biochar or activated carbon. The awareness created on mitigation of carbon dioxide (CO2), which is the major cause of global warming, necessitated developing potential methods and materials for curbing CO2 originating from various sources. Adsorption is the most viable option to mitigate CO2 by using activated carbon which can be derived from various biomass sources. In recent years, activated carbon has been produced from different biomass substances by varying carbonization and activation duration, carbonization and activation temperature, impregnation ratio, and the concentration of the activating agent to improve its surface area and porosity. This review article provides a comprehensive review on utilization, production and characterization of biomass-based activated carbon for CO2 adsorption. Initially, the article discusses the review of research works carried out on utilization of biomass-based activated carbon for CO2 adsorption. Furthermore, the article presents the research works carried out on surface textural characteristics, physicochemical properties, and maximum adsorption capacity of activated carbon obtained from different biomass substances. Finally, the article presents the research works carried out related to the biomass-based activated carbon and the parameters significantly enhancing the CO2 adsorption performance.

      Abstract: Energy & Environment, Ahead of Print.
      China is known for its large industrial sector and diversified energy mix, which could contribute to environmental pollution, as fossil fuels remain China's main source of energy. With the recent drive by the Chinese government to achieve low carbon emissions and further reduce greenhouse gases, this study adds to the existing literature by combining the quantile-on-quantile (QQ) regression and non-parametric techniques to examine the role of economic complexity, nonrenewables energy and renewable energy consumption on the ecological footprint in China over the period 1985Q1–2019Q4. Overall, results show that renewable energy, non-renewable energy use, economic growth and economic complexity affects ecological footprint positively. In addition, the nonparametric causality outcomes revealed that renewable energy, non-renewable energy use, economic growth and economic complexity can significantly predict variations in ecological footprint at different quantiles. We are of the opinion that policymakers in this region should work on the pro-growth mentality of China, which is majorly fossil fuel-driven. This requires an immediate replacement with more eco-friendly sources and energy-saving technologies for economic activities. Otherwise, fulfilling the SDG 13 goals in China will be challenging. For a sustainable renewable energy investment, China should shift to ancillary and spot markets, where the low energy storage and low marginal cost of renewable energy could facilitate higher reduction in electricity cost and encourage higher trading of electricity.

First, the fractional accumulated generation operator, fractional derivative and classic nonlinear grey Bernoulli model are simultaneously coupled to develop an optimised nonlinear grey Bernoulli model that identifies the nonlinear trends in industrial WWE systems. Second, the particle swarm optimization algorithm is employed to determine the optimal model parameters in the newly-designed model. Based on this, simulation studies are conducted to examine the stability of the proposed model. Finally, the model is applied in the industrial WWE system. The results demonstrate that (1) the proposed model outperforms other competitive models in terms of error-value metrics and (2) industrial water use and industrial energy consumption will increase, whereas industrial wastewater discharge will decline. Furthermore, the rationality of the predicted results redis analyzed from a policy perspective.

      Abstract: Energy & Environment, Ahead of Print.
      The global rise in energy consumption makes managing energy demands a priority. Here, the potential of Information and Communication Technology (ICT) in controlling energy consumption is still debated. Within this context, the main objective of the current study is to measure the impact of ICT, its potential benefit, and environmental factors on household electricity demand in Taiwan. A panel of data from 20 cities in Taiwan was collected during the period 2004–2018. We adopted PMG estimation and applied the DH-causality test for analysis. The estimation results show that ICT, carbon emissions, and climate change will drive household electricity demand in Taiwan in the long term. However, ICT has a higher potential to reduce electricity demand in the short-term period. In addition, the results of the causality test reveal a two-way interrelationship between ICT and electricity demand. Our study also found that climate change indirectly affects the use of electricity through household appliances. We also presented several policy implications at the end of this paper.

  • Creating portfolios of firm-specific energy R&D investment under
           market uncertainty

      Abstract: Energy & Environment, Ahead of Print.
      This research determines the optimal distribution of firm-specific energy research and development (R&D) investment that balances firms’ return and risk under market-induced uncertainty. We focus on creating optimal portfolios of target firms and their optimal energy R&D investments that maximize their return on investments (ROIs) for given levels of risk. We employ a stochastic optimization framework that maximizes firms’ ROIs for energy R&D investment, measured by the ratio of the number of patents issued for energy technologies to the amount of annual energy R&D expenditures, for 78 energy firms in South Korea between 2006 and 2017. The findings from our mean-standard deviation tradeoff frontiers are summarized as follows: 1) the tradeoff ratio increases as the weights shift from 100% on maximizing expected ROI toward 100% on minimizing its standard deviation regardless of market conditions and 2) the tradeoff ratio during the downturn is higher than during the upturn. These findings suggest that firms mitigate market-induced risk with a smaller sacrifice in the expected number of issued patents when the initial weight is primarily on maximizing expected ROIs and when the market is experiencing an upturn instead of a downturn. From the distribution patterns of prioritized firms for the two extreme risk preference points along the upturn and downturn tradeoff frontiers, we find that the target firms shift under different market conditions and risk assumptions. These priority shifts highlight the importance of decision-maker flexibility in structuring firms’ portfolios to support energy R&D, depending on the governments’ risk tolerances and market conditions.

      Abstract: Energy & Environment, Ahead of Print.
      This paper examines the causation between economic growth, tourism import, industrialization, renewable energy, non-renewable energy use, trade openness, and environmental sustainability which is proxied by carbon emissions for 8 Asian countries (China, Japan, India, Indonesia, South Korea, Philippines, Thailand, and Vietnam) over 20 years. Causal relations were tested using Pooled Mean Group Autoregressive distributive lag model (PMG-ARDL) and Dumitrescu and Hurlin's (2012) panel granger causality test The PMG-ARDL model results reveal that in the long-run renewable energy usage, economic growth, and trade have a significant negative influence on the emission of carbon, while non-renewable energy usage, tourism import, and industrialization exhibit a significant positive impact on CO2 emissions of the sampled Asian countries. In the short run, renewable energy has a significant negative influence on CO2 emissions. While economic growth exhibit a significant positive influence on carbon emissions in the short-run. Furthermore, the Granger causality analysis reveals that there is a feedback mechanism between industrialization, tourism import, non-renewable energy, renewable energy, and CO2 emissions meaning that the future dynamics of carbon emissions in the sampled countries can be significantly explained by industrialization, tourism import, renewable energy, and non-renewable energy. Contrarily, trade and economic growth are good to explain the dynamics of carbon effusion of the sampled Asian countries in the future but without feedback. It is recommended that policymakers in Asian countries should formulate stringent environmental policies that will encourage industries in these countries to utilize clean energy sources so that economic growth will be achieved simultaneously with carbon neutrality.

  • A new look at asymmetric effect of oil price changes on inflation:
           Evidence from Malaysia

      Authors: Siok Kun Sek
      Abstract: Energy & Environment, Ahead of Print.
      The existing literature that examined the effect of oil price on domestic price inflation only focused on consumer price at an aggregate level. The studies that focused on producer and production levels, and based on disaggregated data are very lack. Besides, previous studies also mainly applied the linear regression approach in studying the effect of oil price. This study seeks to explore the mentioned issues by focusing on sectoral consumer (CPI), industrial (IPI), and producer (PPI) prices of Malaysia. The Markov-switching (MS) regression technique is applied. The models are innovated by incorporating the asymmetric effects of oil price changes. The results reveal different reactions of sectoral domestic price inflation to oil price changes. The oil price has asymmetric effects on domestic price inflation with higher impacts on industrial and producer prices than the consumer price. The effect is larger in sectors that have higher linkages with oil/ energy resources. These sectors are oil-intensive and are sensitive to oil price changes. Among these sectors are the CPI transportation sector, IPI manufacturing, and electrical sectors as well as PPI fuel, chemicals, and manufacturing sectors. However, oil is not the main factor causes to domestic inflation. The main determinants of inflation are real exchange rate, aggregate supply, and demand. Besides, the policy decisions are also influential on price stability. The sectors of CPI transportation, PPI animals & vegetable oils, and PPI fuel have a high tendency to increase prices and should be well-monitored.

      Abstract: Energy & Environment, Ahead of Print.
      Using crumb rubber particles obtained from end-of-life tires as aggregate in concrete can reduce the environmental overburden caused by the huge accumulation of these scrap tires. However, reduction in the mechanical properties of concrete is observed with the incorporation of rubber aggregates. To counter this detrimental effect of crumb rubber in concrete, amorphous metallic fibers are added to balance the loss in strength and durability issues. Mechanical characteristics along with the fracture energy of rubberized fiber-reinforced mortar are presented here. Four mortar mix compositions were investigated; the first one is reference mortar (control mortar), the second mix containing 30 kg/m3 of metallic fibers, the third mix containing 30% of rubber aggregates as replacement of sand by equivalent volume and fourth containing both rubber aggregates and metallic fibers with the dosage 30% and 30 kg/m3, respectively. Compression tests, modulus of elasticity and direct tension tests were conducted for mechanical characterization. Deformation capacity, residual post-cracking strength and fracture energy of these composite mortar mixes were evaluated through uniaxial direct tension tests. The fracture energy was determined from the obtained complete softening curves. Test results show a reduction in mechanical properties with the incorporation of crumb rubber as aggregates in mortar. However, a significant increase in fracture energy was observed in rubberized fiber-reinforced mortar mixes. Moreover, the mortar mixes containing both rubber aggregates and metallic fibers show positive synergetic effect resulting in enhanced post-cracking residual tensile strength, strain capacity and energy dissipation capacity.

      Abstract: Energy & Environment, Ahead of Print.
      The present research focuses on the experimental study of the effect of alkaline pretreatment with NaOH on biogas production. Different concentrations of NaOH, i.e. 1, 2.5 and 5% (w/w), were tested on the lagoon station's sludge (dry basis) at room temperature for 24 h. The results obtained after 60 days of digestion, through the cumulative volume of biogas recorded, clearly indicate a positive effect of the chemical alkaline pretreatment on the anaerobic digestion since the amount of biogas produced increased by 42.6% when the NaOH concentration was close to 2.5%. This concentration is considered optimal under the chosen conditions. Indeed, inhibition of the methanogenic activity and a blockage of the digestion process are observed beyond this concentration. These results suggest that the alkaline pretreatment can improve the energy efficiency of the obtained biogas (CH4 content) and reduce the residence time.

      Abstract: Energy & Environment, Ahead of Print.
      Solar collectors absorb solar radiation at the focus of solar concentrating systems as heat energy which is further transferred to nanofluid. Entropy creation in Maxwell nanofluid flow over an infinite horizontal surface of a porous media is the subject of the current investigation. A non-linear stretching surface then induces a parabolic trough solar collector (PTSC) flow. The thermal boundary layer is studied using a modified version of Buongiorno's Model. As a result, the PDEs, which encompass the physical aspects of the issue, must be transformed into solvable and boundary-constrained ODEs. By using a proper similarity transformation, boundary conditions and partial differential expressions are reduced to a set of non-linear ordinary differential equations. The Keller box method is used to find approximate solutions to ODEs. Tests are carried out on a nanofluid known as Copper-engine oil (Cu-EO). The Nusselt number was lowered, but the skin friction coefficient was increased as a result of a substantial magnetic parameter. In addition, Reynolds number and Brinkman number are used to measure fluctuations in viscosity, and, as a result, entropy variations throughout the domain are increased. Temperature decreased due to chemical reaction and Schmidt number, while thermal radiation increased skin friction and Nusselt. According to the current analysis, the heat collector has enhanced PTSC with Maxwell nanofluid.

      Abstract: Energy & Environment, Ahead of Print.
      The COVID-19 pandemic remained a global risk factor and integrated into various means in the functioning of companies, economies and financial markets. Therefore, this paper investigates how COVID-19 influences the energy market in the main financial markets (China, France, Germany, Italy, Spain and the United States), using time series from February 28, 2020, to November 3, 2020. The goal of this research is to investigate the asymmetric impact of COVID-19 from leading financial markets on energy commodities. In this regard, the non-linear auto-regressive distributed lag (NARDL) framework is employed to capture the long-run asymmetric reactions. The econometric design allows to explore the long-term asymmetric reactions of dependent variables through positive and negative partial sum decompositions of changes in the explanatory variables. The quantitative results show a significant long-run asymmetric interdependence between the number of new SARS-CoV-2 incidence and mortality and the daily percent change in close price of future contracts pertaining to Brent oil, crude oil WTI, carbon emissions, gasoline RBOB, heating oil, Chukyo kerosene, and natural gas. Furthermore, no asymmetry is found in the case of ethanol and fuel oil futures. The novelty of this article is the study of the impact of COVID-19 on the energy sector during the first two waves of COVID-19 by applying the NARDL model that allows to capture long-term asymmetric reactions. Certainly, further research on this topic is necessary due to the permanent shifts in the pandemic, as well as the availability of longer data periods on COVID-19.

      Abstract: Energy & Environment, Ahead of Print.
      Along with the increasing aging population (AP) and global interconnectedness in the Mediterranean bloc comes climate change issues faced by the Mediterranean region in its trajectory to energy security and sustainable development. To meet the continuous energy consumption demand while cutting down natural resources extraction and exploitation with a view to minimizing environmental impacts, the policy structure in these countries may require readjustment, which is the motivation for the present study. This study advances a strategic framework for investigating the impact of natural resources rent as well as aging reliance on carbon emissions in the Mediterranean region for the annual frequency data from 1990–2016. Using quantile regression to analyze the highlighted variables, empirical results shows that both income and natural resources rent have an inverted U-Shaped connection with CO2 emission, which affirms the Environmental Kuznets Curve (EKC) hypothesis. Subsequently, globalization and energy use show a positive relationship with emissions while AP is negatively correlated with emissions. Depending on the outcomes of this analysis, a multi-stage Sustainable Development Goal (SDG) framework has been developed and SDG- 7, SDG -13 as well as SDG-8 were examined in this context. While these three SDGs are the main targets of the study, the SDG System has also provided a way to test other SDGs.

      Abstract: Energy & Environment, Ahead of Print.
      This study examines the complex relationship between carbon emissions and technological progress in a sample of 60 countries divided into four income groups for the period 1989–2018. For robustness purposes and due to the broad definition of technology, we use six different proxies to represent technology: Information and telecommunication technology (ICT), patents, public R&D expenditure, Total factor of productivity (TFP), science and technology publications. After applying the fixed-effect method with Driscoll and Kraay standard errors, ICT variables appear to be good instruments for carbon reduction in the full sample. However, R&D expenditure and patents do not significantly impact carbon emissions. TFP increases carbon emissions, while science and technology publications are negatively related to carbon emissions. The analysis shows mixed results for the various country income groups and all indicators.

      Abstract: Energy & Environment, Ahead of Print.
      Due to the intermittency of renewable energies, their acceptances in electricity market are lower than fossil energies. Therefore, it is necessary to overcome the development resistance through portfolio re-equilibrium. Balance supply and demand in markets involving different stakeholders to optimize return on investment. Compared with the past, this paper proposes an integrated optimization with combined meta-heuristic for wind-solar-hydro system. It investigates to coordinate the interactions of power stations and power grid with their internal conflicts respectively. Specifically, the investment profit, the investment volume and the investment risk are considered as the optimized objectives for wind-solar-hydro system. However, power grid takes operation efficiency, surplus electricity and carbon emissions into account to be the optimal objectives. They are composed to establish a bi-level programming model. Moreover, an improved particle swarm optimization is utilized to deal with the problem-orientated model with NP-hard complexity. Finally, to verify the feasibility of the proposed model, a case of wind-solar-hydro system from Panzhihua located in southwest China is conducted. The results showed that portfolio re-equilibrium strategies had the potential to push forward sustainable development. Secondly, generating capacity was positively affected by the initial investment volume. However, the investment profit did not absolutely rise with the grow of investment risk. Thirdly, profit-oriented strategies were conducive to carbon emissions reduction. But risk-oriented strategies can reduce surplus electricity and increase the stability of electricity purchase schemes.

      Abstract: Energy & Environment, Ahead of Print.
      The activities of humans on Earth have increased the global concern for climate change, ecological distortions, and environmental deterioration. These concerns have warranted regulations that relate to environmental preservation and sustainability. However, the efficiency of such regulations in emerging economies is yet to be ascertained as conclusions from various findings still remain murky. We explore how environmental regulations affects ecological footprint (EFP) using the cross-sectionally augmented autoregressive distributed lag (CS-ARDL) model, augmented mean group (AMG), and the common correlated effects mean group estimators (CCEMG) in the eleven fastest emerging economies (N11). The findings reveal that environmental regulations are not efficient in abating environmental deterioration. Economic growth, trade, and energy consumption invigorate the EFP. The country-specific findings confirm that energy consumption and economic growth promote environmental degradation in all the N11 countries, and the outcome was consistent across all estimators. Finally, policy directions are discussed along with the limitations of the study.

  • Renewable energy taxes and environmental impacts: A critical reflection
           from the wind tax in Spain

    • Free pre-print version: Loading...

      Authors: Rosa Mª Regueiro-Ferreira, María Cadaval Sampedro
      Abstract: Energy & Environment, Ahead of Print.
      In recent decades, wind energy has undergone significant progress, with the contribution of countries such as China, the United States, Germany and Spain standing out, although there is no single comprehensive model for promoting renewable energy worldwide. In Spain, the regions of Galicia, Castilla-La Mancha and Andalusia have led this process, with significant changes in their contribution depending on the economic situation and the varied legislative framework in force at any given time. Although wind energy is less harmful to the environment, it is not harmless, and environmental impact and its penalisation is one of the key elements in the applicable regulations. In the case of Spain, the three regions mentioned above, out of a total of seventeen, apply their own taxes to tax the environmental impact of wind energy. The aim of this paper is to describe and compare the wind tax applied in the aforementioned regions from 1995 to 2020; to characterise wind taxation socio-economically, and to assess the suitability of this type of taxation to tax the environmental impacts associated with wind energy activity in Spain. The differences in tax treatment are notable and it is observed that the concept of environmental impact has been anchored in the past and, today, older wind farms with less powerful wind turbines are those that bear a greater tax burden, while more modern, more powerful and larger wind farms (with a significant environmental, acoustic and visual impact) may even be exempt from taxation.

      Authors: Tomiwa Sunday Adebayo, Seyi Saint Akadiri, Joshua Sunday Riti, Ada Tony Odu
      Abstract: Energy & Environment, Ahead of Print.
      In this paper, we examine whether geopolitical risk influences environmental degradation, while controlling for non-renewable energy consumption, economic growth and trade openness, using a quarterly dataset from 1985Q1 to 2019Q4. The choice of India as a case study is based on a number of reasons. India is a developing country, which produces approximately 3.2% of global GDP. Also, India produces almost 17.7% of the world population. The country also emits about 6.8% of global carbon emissions, and according to the 2020 report of the consulting firm Eurasia, India is ranked fifth in terms of geopolitical risk. This study adds to the existing literature by using the quantile-on-quantile (QQR) regression to examine the effect of geopolitical risk on environmental degradation, as well as highlighting the implications of geopolitical risk on environmental sustainability. Based on empirical estimation, we find that geopolitical risk increases and decreases carbon emissions in India. That is, geopolitical risk increases environmental degradation at middle quantiles and decreases environmental degradation at lower and higher quantiles. In addition, we find that non-renewable energy consumption, economic growth and trade openness impede environmental quality in India. Thus, we are of the opinion that policymakers, when making policy decisions on environmental quality, should factor in geopolitical risk in two areas, mitigation and channel of escalation, among other policy suggestions.

      Abstract: Energy & Environment, Ahead of Print.
      This study examines socioeconomic and spatial factors and its influences on the outcomes of environmental-health through “multi-drug resistance tuberculosis” (MDR-TB) treatment regimes in China. For this purpose, a survival analysis is conducted by applying “multivariable Cox Proportional Hazard model” on secondary data starts from 2010 to 2019. The data set is consisting of six hundred and fifty five (655) TB patients from different hospitals of China. The findings of this study indicate us that there is no alteration in patient survival rates between the two treatment departments, hospital and ambulatory care. The spatial characteristics of time expenditure and medical expenditure are significantly correlated with “supporting distance bias methods” and “environmental health results”. On the other side, travel expenditures and male gender results show negatively associated with the “environmental-health outcome”. This study reveals with these remarks that Ministry of Health, China should take serious actions to control MDR-TB and launch a comprehensive policy with the help of WHO recommendation.

      Authors: Tomiwa Sunday Adebayo, Seyi Saint Akadiri, Usenobong Akpan, Bisola Aladenika
      Abstract: Energy & Environment, Ahead of Print.
      Being among the highest emitters of greenhouse gases globally, the G7 countries have pledged to halve their carbon emissions by 2030, relative to 2010. This is in clear recognition of the need to transit from carbon energy to more sustainable solutions that are climate-friendly. In view of this, understanding how financial globalization contributes to the realization of those pledges becomes necessary. In this paper, we introduce two major innovations to the literature on financial globalization and environmental degradation. First, in terms of methodology, we apply the quantile-on-quantile regression (QQR) approach with a nonparametric technique over the period 1970Q1–2018Q4. The combination of these techniques has so far received limited attention in the literature. Second, we test for an asymmetric nexus between financial globalization and carbon emission in the G7 economies—Canada, France, Germany, Italy, Japan, the United Kingdom and the United States—as they present an interesting area of research focus. Empirical results from the QQ regression show an emission-increasing effect of financial globalization on environmental degradation in the G7 nations. Furthermore, in order to assess the causal effect of financial globalization on environmental degradation, we apply the nonparametric causality technique. Overall, results from the nonparametric estimations show that financial globalization significantly predicts variation in environmental degradation across quantiles. From a policy standpoint, economic and political frameworks in these nations should be directed towards enhancing higher financial inflows that are in line with the stated economic and environmental policies, among other policy suggestions.

      Abstract: Energy & Environment, Ahead of Print.
      The evaluation of reanalysis and analysis data (estimated data) against in-situ measured data is essential to find uncertainties before its use for wind resource assessment. The performance evaluation of four different generations reanalysis datasets (NCEP-CFSR, NCEP-DOE, NCEP-NCAR and JRA-55) and two analysis datasets (NCEP-FNL and NCEP-GFS) was done against measured data for six sites using statistical analysis. A comparison of monthly mean time-series, Weibull probability distribution function and wind rose diagram of measured and estimated data was performed. The MBE and RMSE for wind speed range from −2.18 to 2.01 m/s and 1.34 to 3.00 m/s respectively; whereas MBE and RMSE for wind direction range from −34.34° to 13.90° and 40.58° to 71.28° respectively for six sites using all datasets. NCEP-CFSR data show promising results for most of the sites with the lowest errors and better correlation coefficients. NCEP-CFSR data being the new generation reanalysis having higher spatial resolution show better results compared to other reanalyses and analyses. The reanalysis and analysis wind data can be used as alternative to measured data to assess wind energy potential.

      Abstract: Energy & Environment, Ahead of Print.
      To address the future growth in energy demands, complete renewable power generation from environmental assets demands unique methodologies from every investigator. Wind energy harvesting in residential areas is one such approach. But the urban landscape and the physical challenges restrict the erection of small-scale wind turbines. Further, a significant degree of uncertainty leads to a lack of awareness of how dispersion in urban environments impacts turbine performance. This research looks into the potential productivity of wind turbine installations in urban areas, considering turbulence. These unique ambient conditions prevailing in a dynamic environment compared to flat terrains have made the harnessing of wind energy very difficult. Many researchers are still trying to find an effective methodology in these constrained circumstances. Since the characteristics of small-scale wind turbine models are undetermined, large-scale turbines fared well compared to small-scale wind turbine models. The feasibility and success of small and medium turbines in community homes were investigated in this study. The origins of the very uncertain nature of atmospheric boundary layer limitations are discussed in this work and subsequent successful developments by different researchers.

      Abstract: Energy & Environment, Ahead of Print.
      Inherent fuel flexibility of micro gas turbine (MGT) makes the engine a promising energy solution to remote Canadian communities that are not connected to the North American electricity grid, where bio-oils derived from locally available bio-mass may be utilized to meet local power and heat demands to reduce fossil fuel consumption. The switch to bio-oils enabled by MGTs reduces not only carbon footprints but also operating expenses due to high transportation costs of fossil fuels. However, MGT efficiencies are greatly reduced at partial loads. This work investigates the feasibility of addressing MGT efficiency drops at partial loads by incorporating MGT with a Battery Energy Storage System (BESS) to form a hybrid system so that the MGT can be operated at near full power at all times for better efficiencies. In this study, a daily power demand profile of a typical Canadian household is adopted for optimizing battery size and MGT operating strategies. By optimizing MGT daily start time and the engine's threshold partial load factor, the specific fuel consumption and battery size can be minimized for a specific number of households on a micro-grid supported by the MGT-based hybrid power system.

      Abstract: Energy & Environment, Ahead of Print.
      Diuretic hydrochlorothiazide (HCTZ) has been detected in drinking and environmental water. Since HCTZ exhibited some toxic effects on the environment, it is essential to propose safe and economical ways of its removal. The influence of water quality on the removal efficiency of HCTZ from the environment was observed. The stability of HCTZ was investigated in ultrapure (UPW), tap, and two different environmental waters, by hydrolysis, photolysis, and indirect photolysis under simulated solar irradiation (SSI) and UV irradiation. Also, experiments were conducted at temperatures of (5  ±  1) °C and (25  ±  1) °C, in the dark. Comprehensive experimental and computational analysis was performed to examine the stability and reactivity. The results show that HCTZ is susceptible to hydrolysis. Photolysis and indirect photolysis were efficient under UV irradiation, wherein HCTZ was entirely degraded after 180 min of irradiation in UPW. Chloride ions, carbonates, calcium, and magnesium ions present in natural waters inhibited the degradation of HCTZ. This diuretic has significant interaction with •OH radicals. A 4-amino-6-chlorobenzene-1,3- disulfonamide (ABSA) was observed as a stable degradation product, and ABSA formation's degradation mechanism was proposed. Mineralization of HCTZ was above 50% in H2O2/UV system in UPW after 180 min of irradiation.

      Abstract: Energy & Environment, Ahead of Print.
      Parabolic trough solar collectors (PTSCs) are commonly used in solar thermal implementations to achieve high-temperatures. The current investigation looks at entropy formation and the effect of nano solid particles on a parabolic trough surface collector (PTSC) mounted aboard a solar-powered ship (SPS). The non-Newtonian first grade viscoelastic type, as well as a porous medium and Darcy-Forchheimer effects, were utilised in the current study. The flowing of PTSC was created by a non-linear stretching sheet, and the changing thermal conductivity, heat source, and viscous dissipation effects were used to calculate the heat flux in the thermal boundary layer. To convert partial differential equations (PDEs) into solvable ordinary differential equations (ODEs) with boundary-constraints, a similarity transformation strategy was used. The boundary-constraints and PDEs have been reduced to a set of non-linear ODEs (ordinary differential equations). To reach the approximated solution of ODEs, the Galerkin finite element method (G-FEM) is used. As working fluids, copper-sodium alginate (Cu-SA) and molybdenum disulfide-copper/sodium alginate (MoS2-Cu/SA) hybrid nanofluids were used. According to the findings, the permeability factor diminished the Nusselt number whilst boosting the skin friction factor. Furthermore, overall entropy variance throughout the domain was increased for flow speeds using the Reynolds number, and viscosity changes were tracked using the Brinkman number. When compared to MoS2-Cu/SA, using Cu-SA nanofluid boosted thermal efficiency by 1.3–18.8%.

      Abstract: Energy & Environment, Ahead of Print.
      The debate regarding mitigation of carbon dioxide emissions and fiscal decentralization has gained extreme attention, but only a little evidence supports this issue. Therefore, this study adopts fiscal decentralization, green technology innovation, and institutional efficiency that reduce environmental degradation and help to create a sustainable environment in seventeen developed countries. This study applies a novel Methods of Moment's Quantiles Regression (MMQR) which helps to deal with asymmetricity, structural change and non-normality. The overall results exhibit emissions mitigating effect of fiscal decentralization, green technology innovation and institutional efficiency. However, the emissions mitigating effects of fiscal decentralization is the lowest for lower quantiles and the highest for higher emissions quantiles. In contrast, emission reduction effect of green technology innovation and institutional efficiency is higher for lowest quantiles and lower for highest quantiles. These results confirm the asymmetric effect of fiscal decentralization, green technology innovation, and institutional efficiency on carbon emissions, and validating that their effect is not alike across all distribution, rather significantly varied at lower, medium, and higher quantiles. These results offer valuable suggestions to improve the environmental sustainability.

      Authors: Liangliang Liu, Yonghao Guan
      Abstract: Energy & Environment, Ahead of Print.
      Since the reform of the tax-sharing system in 1994, the regulation of the central government to local governments has relied on the mean of intergovernmental fiscal transfers (IFTs) to a certain extent. However, the existing literature has not yet explored the influence of fiscal decentralization (FD) on energy consumption in the presence of IFTs. Thus, this study empirically examines the influences of FD and IFTs on energy consumption by using panel data for 30 Chinese provinces during the period of 1998–2019. Results indicate that FD and IFTs have positive effects on energy consumption. Moreover, the positive influence of FD on energy consumption is strengthened by the improvement in IFTs. In addition, FD and IFTs affect energy consumption through industrial structure upgrading. In terms of policy implications, this study suggests that China may further reduce energy consumption by appropriately reducing the degree of FD, optimizing the intergovernmental fiscal transfer system, and promoting the upgrading of industrial structure.

           Emissions: Evidence from the MINT countries

      Authors: Tomiwa Sunday Adebayo, Seyi Saint Akadiri, Ilham Haouas, Husam Rjoub
      Abstract: Energy & Environment, Ahead of Print.
      Since the global economic crisis, researchers and policymakers have paid close attention to the carbon emissions and financial development interrelationship, and some researchers believe that financial development can aid in abating the emissions of carbon. Thus, the objective of this study is to analysis the impacts of financial development of the MINT countries (Mexico, Indonesia, Nigeria and Turkey) on their CO2 emissions year on year via historical data covering the period 1969–2019. The full-sample bootstrap non-Granger causality test outcomes for Mexico and Turkey reveal that there is a one-way causal association from financial development to CO2 emissions. Short and long-run instability is shown through a range of parameter constancy tests utilized to investigate the stability of the estimated vector autoregressive models. This implies that the full-sample causality tests are inadequate, necessitating the use of a time-varying (bootstrap) rolling-window technique to address parameter non-constancy and prevent pre-test distortion; therefore, this research uses rolling-window bootstrap estimation. Empirical results from the rolling-window bootstrap estimation show that the nexus between financial development and carbon emissions is date-stamped. These outcomes indicate that significant feedback causal associations exist between financial development and CO2 emissions in sub-sampled periods in the MINT nations. In addition, we observe emission-decreasing and emission-increasing effects of financial development in the sampled countries across period. One of the study policy recommendations is that policymakers in these nations through monetary authority should mop-up financial resources from institutions showing emission-increasing tendencies to institutions and/or sectors with emission-reducing tendencies.

      Abstract: Energy & Environment, Ahead of Print.
      The Indian Point Energy Center (IPEC) supplied approximately 25% of New York City and the surrounding area’s electricity. As of April 2021, the nuclear power plant has been shut down, creating the need for other energy sources to meet the demand. This scoping analysis study examined the ability of different renewable pathways (solar photovoltaic (PV), willow biomass, onshore wind, and two combinations of these) to replicate the IPEC’s electricity generation profile. Five renewable electricity generation supply profiles were developed and analyzed from monthly and seasonal perspectives. The timing and alignment of the different generation supply profiles relative to that of IPEC were analyzed. Productivity in MWh hectare−1 year−1 and economic feasibility of the renewable electricity pathway scenarios were assessed. This study identified the solar PV pathway as the most efficient in terms of electricity land productivity at 731.9 MWh hectare−1 year−1, while the willow biomass pathway was the least efficient at 15.2 MWh hectare−1 year−1. However, in terms of net electricity output to the grid, the solar PV pathway was the least productive at 137,610 MWh/year, while the onshore wind with willow biomass pathway produced the highest net output at 894,801 MWh/year. These findings are important at a time when policymakers are considering or implementing plans to phase out nuclear power in favor of renewable electricity.

      Authors: Mingran Wu
      Abstract: Energy & Environment, Ahead of Print.
      To figure out at what extent of China's investment in energy technology in recent years has helped economic growth and improved the environment. From the basic theory of environmental regulation’s influence on energy consumption efficiency, this study uses the super-efficiency slack base model to measure the green energy efficiency of 30 provinces in China from 2010 to 2019, and uses the kernel density function to analyze evolution trajectory. Then, the spatial Dubin model is used to test the influence of some important economic variables. The results of value show that although China's green energy efficiency improved significantly from 2010 to 2019, the overall performance was lacking. However, the overall efficiency value was significantly improved during the study period. Moreover, the efficiency value was closely related to the performance of economic development. From the dynamic trajectory perspective, efficiency values of all years show the type of "two peaks".Altough the width between the two peaks did not change noticeably, but the efficiency still had a significantly improved. In addition, according to the results of spatial economic regression analysis, eco-environmental constraints, foreign direct investment, and industrial agglomeration were not conducive to the efficiency value, while industrial structure and manufacturing enterprise scale had positive effects. In addition, the influence effects had obvious spatial phenomena. Therefore, for the Chinese government, enterprises and society, the next step is not only to vigorously exploit energy-saving and emission reduction technologies to improve energy consumption efficiency but also to establish reasonable environmental regulation policies to push enterprises to produce in a cleaner way. Additionally, a reasonable regional development plan should be established to promote the rational distribution and flow of the energy industry across different places. This paper provides a novel perspective for the study of energy input and usage.

      Abstract: Energy & Environment, Ahead of Print.
      With the deepening of government reform, the Chinese government has strengthened the functions of public service and social management. Public policies are increasingly concerned with residents’ well-being. However, environmental quality, which can be regarded as a visual indicator to reflect the performance of environmental protection and the quality of public service, is still not optimistic in China. Thus, we wonder if there exist deep relationships among public expenditure, environmental pollution, and subjective well-being. By combining the data from the Chinese Family Panel Survey (CFPS) with relevant government statistics, we find that public expenditure improves residents’ well-being, whereas environmental pollution has a negative effect. More importantly, environmental pollution is found to moderate the relationship between government expenditure and residents’ subjective well-being. These findings not only prove the extra costs of environmental degradation, but also suggest that good performance of environmental governance should be emphasized in promoting human welfare.

      Abstract: Energy & Environment, Ahead of Print.
      This work aims to analyze the impact of population aging on the relationship between economic growth and carbon emissions, and the relationship between energy consumption and carbon emissions. To this end, based on the panel data of 36 OECD countries from 1996 to 2016, the panel threshold regression model was developed. In the model, per capita carbon emissions are the explained variables, economic development (per capita GDP) and per capita energy consumption are the core explanatory variables of the two models respectively, population aging is the threshold variable, population size, technological innovation level, the degree of urbanization, industrial structure and energy intensity are control variables. The empirical results show that there is a population aging threshold effect between per capita GDP and per capita carbon emissions, and between per capita energy consumption and per capita carbon emissions. This means that population aging is an important factor that affects the relationship between economic growth and carbon emissions, as well as energy consumption and carbon emissions. Although economic growth and carbon emissions, energy consumption and carbon emissions were coupled, the coupling state decline when the population aging crosses the threshold value. This indicates that the population aging contributes to the decoupling of the economic growth and carbon emissions, and the decoupling of energy consumption and carbon emissions. Finally, on the basis of the proposed model, a robust analysis of the variable of trade openness was conducted to prove the validity of this research.

      Abstract: Energy & Environment, Ahead of Print.
      Regardless of the challenges facing renewable energy development in today’s world, hydropower is still the most broadly patronized source of renewable energy, with a global installed capacity of 1330 GW in 2020. Hydropower contributes the largest share of the total installed renewable energy globally, accounting for more than 54% of renewable energy generation capacity worldwide. In this 21st century, the quest for a global shift to a carbon-emission-free future has been epitomized by China through its way of overcoming some crucial challenges to becoming the number one hydropower producer in the world. China is currently the top exporter of its hydropower technology and expertise to a reasonably significant number of countries across the globe. Due to failed energy policy implementation, Nigeria, on the other hand, has been languishing in air pollution from fossil fuel energy generation due to poor and erratic electrical energy supply from the grid, despite its enormous hydropower potential. However, a resurgence of Nigeria’s National renewable energy and Energy Efficiency Policy in 2015 resulted in a consortium signed between China and Nigeria, placing China at the helm of reviving Nigeria’s hydropower industry, yielding some positive outcomes so far. A partnership between technologically advanced and undeveloped countries, particularly Africa, is required to overcome significant avoidable hydropower constraints towards attaining their full hydropower output potential. In this way, the imperative to guaranteeing a globally cleaner and more sustainable energy future is more reassuring.

      Abstract: Energy & Environment, Ahead of Print.
      Anthropogenic CO2 generations from use of fossil resources has led to catastrophic climate problems. Biochar is a promising material for CO2 capture and storage in soil, because it does not require additional storage space. To produce biochar, pyrolysis is required in an oxygen-limited condition. In an attempt to offer more environmentally benign route for biochar formation, this study introduced CO2 as a reaction agent. Using rice husk as a model compound, biochars were produced under CO2 and N2 condition. Porosity of rice husk biochars (RHBs) were enhanced under CO2 condition, because CO2 affected to formation of nano-sized pores. pH and moisture retention capacity of garden soil was controlled with an addition of RHBs. Mixtures of garden soil and RHB were also used as cultivation media for growth of barley grass, and plant growth in the mixtures was improved by 20% comparing to garden soil. Moreover, CO2 contributed to enhanced syngas generation during biochar production through gas phase reactions between CO2 and volatile compounds. Thus, this study proved that CO2 is a useful reactant for pyrolysis of biomass waste.

      Abstract: Energy & Environment, Ahead of Print.
      Liquid desiccant air-conditioning system is an energy-efficient choice for heat and moisture independent treatment in buildings, especially for the large dehumidification load. Electrodialysis regeneration is a novel and reliable regeneration method for liquid desiccants, which is suitable for hot and humid climates. In this paper, the performance of the electrodialysis regenerator for regenerating lithium chloride and lithium bromide solutions was studied experimentally, and the current efficiency of the electrodialysis regenerator for regenerating these two solutions was compared. Through analysis, the solute molecular weight was coupled into the current efficiency model, and a new current efficiency model of electrodialysis regenerator for regenerating these two solutions was established, which considers the solute molecular weight of liquid desiccant and can be extended to more liquid desiccants in the future. Furthermore, the performance of the liquid desiccant air-conditioning system using electrodialysis regeneration with these two solutions is compared based on this model. The results show that when lithium chloride solution is applied as liquid desiccant, the system performance coefficient (COP, ratio of cooling capacity to energy consumption) is between 1.16 and 4.49, while the performance coefficient of the system is between 2 and 8.3 when the system uses lithium bromide solution.

      Abstract: Energy & Environment, Ahead of Print.
      The effects of performance and emission parameters of a mono-cylinder CI engine have been studied using new alternate fuel: Lemongrass oil (LGO) with nano additive (Cerium Oxide). The study focuses on a novel biosynthesis method (Plant-mediated synthesis) of CeO2 nano-additives from the Azadirachta indica plant, which is less toxic and more compatible with other chemical methods. The biosynthesis method is a simple, high-yielding, environmentally friendly alternative to chemical methods. Recently, a green technique based on impulsively decreasing elements such as polysaccharides, microorganisms (bacteria and fungas), or plant extract has been developed. This is due to the fact that the process is a simpler, non-hazardous, and environmentally friendly alternative technique when compared to the intricate chemical techniques of synthesis of nano-additives. The engine tests were carried out by using three different volumetric percentages (LGO25, LGO25 + 50 ppm and LGO25 + 100 ppm) and related with base diesel. The test outcomes revealed that the BSFC decreased by 4.98% and 6.83% and BTE increased by 1.76% and 2.27% at LGO25 + CE 50 ppm and 100 ppm concentrations, correspondingly. The CO emission decreased by 18.18% and 24.2%, HC emission decreased by 3.03% and 9.1%, NOx emission decreased by 14.8% and 31%, Smoke emission decreased by 10.5% and 15.1% for LGO25 + CE 50 ppm and 100 ppm correspondingly.

      Abstract: Energy & Environment, Ahead of Print.
      The worldwide increasing energy demand, interest in alternative energy production and limited resources have made it inevitable to turn to recovering wastes, such as waste tires. Waste tires with annual increase of 2%, corresponding to significant reserves all over the world, brings a serious environmental pollution. In this study, energy recovery was planned considering environmental pollution caused by waste tires and waste cooking oils, both. Accordingly, performance and emission analyzes were carried out using fuels formed by mixing pyrolytic oil obtained from waste tires (WTPO) and biodiesel obtained from waste cooking oil with diesel fuel in a single cylinder engine. The experiments are carried out at 2800 rpm and at full load condition. The findings of engine performance and exhaust emissions were evaluated. While the maximum brake specific fuel consumption (Bsfc) value was determined as 2100 g/kWh for blend fuel of 30% biodiesel and 10% WTPO in diesel fuel, the maximum brake thermal efficiency (Bte) value was determined as 33.541% for P30 fuel. The crank angles yielding maximum in-cylinder pressures approach to top dead center, with increasing biodiesel fraction while keeping WTPO fraction constant. While the increase in the amount of WTPO in the test fuels has an effect on the increase of CO emissions, and increasing biodiesel ratio has reduced the CO emissions. Also the use of biodiesel without WTPO increases NOx emissions slightly, while providing an effective reduction at high WTPO fractions. At low WTPO fractions, biodiesel has reduced HC emissions, while at high WTPO fractions has increased.

      Abstract: Energy & Environment, Ahead of Print.
      Followed by the extensive activation of demand side entities, the anti-competitive and monopolistic aspects of distribution system operator (DSO) is becoming more apparent. The business model of the DSO and its regulations are not capable enough to fully leverage the capacity of emerging technologies and responsive prosumers. This paper criticized the challenges/deficits revolving around the conventional DSO model and proposes an interactive platform based on the sharing economy business model at the network level. The electricity distribution stakeholders’ organization (EDSO) as the substitute of DSO in active distribution networks is developed based on the collaborative governance decision-making model. The EDSO has the privilege to legislate on the platform operation and its main policy is to preserve the public interest as well as the integrity of electric distribution system. The superiority of proposed operation model is its non-monopolistic and non-profit nature which materializes the perfect competition of active customers and guaranties their maximum utilization.

      Abstract: Energy & Environment, Ahead of Print.
      The purpose of this study is to explore the relationship between financial instability and carbon dioxide (CO2) emissions in India from 1980 to 2020. The Autoregressive Distributed Lag (ARDL) model is used to measure long-run and short-run dynamics, followed by the Vector Error Correction Model (VECM) to determine the causal direction. As per the findings of the study, financial instability has an insignificant effect on CO2 emissions. However, economic development, energy use, and urbanization have a detrimental effect on environmental quality because it releases a significant amount of CO2 emissions into the environment. Our empirical findings confirmed the presence of an environmental Kuznets curve. The outcomes of the VECM show that the long-run causality can be noticed in CO2 emissions, financial instability, energy use, and urbanization. Furthermore, the validity and reliability of the results were verified by using a variety of diagnostic tests. This research presents novel results that add to the current literature and may be of particular importance to the country's policymakers regarding the financial system and its importance in environmental problems.

      Abstract: Energy & Environment, Ahead of Print.
      As the primary energy source derived from the sun, solar energy is widely utilized in various technologies, including photovoltaic cells as well as the solar types of energy plates, street lights, and water pumping. This era is about studying solar radiations and a way to active enhancements in solar power pump (SWP) efficacy with the use of solar radiations and nanotechnology. Communication is structured to examine the capability of SWP in terms of transfer of heat using a hybrid nanofluid passing through a parabolic trough surface collector (PTSC) placed inside the pipeline of SWP. Solar radiation has been considered a heat source. The performance in terms of heat transfer of the SWP is scrutinized for various effects like porous media, viscous dissipation, radiative heat flux, and Cattaneo–Christov heat flux (C–CHF). Entropy generation analysis is also conducted for Prandtl – Eyring fluid (P-EF). The simulated momentum and energy equations were solved using the Keller box technique, which is a well-known numerical approach. For this work, Prandtl – Eyring hybrid nanofluid (P-EHNF) has been considered, consisting of double diverse kinds of nanotubes (NT), including single-walled carbon nanotubes (SWCNT) and multi-walled carbon nanotubes (MWCNT) in the rich, viscous fluid of kind Sodium Alginate (SA). The impact of various parameters on velocity, temperature fields, shear stress, coefficient of drag force, and Nusselt number are investigated and demonstrated in graphs and tables. The SWP experience an enhancement in the transfer of heat for amplification of the parameters of thermal radiative flow as well as viscous dissipation. In comparison with conventional nanofluid, hybrid nanofluid performs better in heat transmission. The thermal efficacy of MWCNT/SWCNT-SA over SWCNT-SA got down to a minimal level of 39.9% and peaked at 42.2%.

      Abstract: Energy & Environment, Ahead of Print.
      This paper assesses the nexus between natural resource rent, hydropower energy consumption and ecological footprint for environmental sustainability incorporating with economic performance by using yearly data from 1970 to 2017. To this end, the long run steady-state relationship among investigated variables has been analyzed by using newly established Residual Least Squares (RALS) method and confirmed for Turkish economy. The directions and magnitudes of the effects of these variables on ecological footprint were tested by using Dynamic Ordinary Least Squares (DOLS) technique. The findings, except hydropower energy consumption, reveal statistically significant and positive effects of investigated variables on ecological footprint. Moreover, the inverted U-shaped EKC hypothesis was also affirmed between economic performance and ecological footprint. The causal relationship among these variables were also tested by using VECM Granger causality test The unidirectional Granger causality relationships were found that they are running from ecological footprint, and natural resource rent to economic performance, from natural resources to ecological footprint and from natural resource rent to economic performance in Turkish economy. Additionally, the bidirectional causal relationship has been detected among economic performance and ecological footprint in Turkey. The findings highlight the importance of investigated variables on ecological footprint in Turkey.

      Abstract: Energy & Environment, Ahead of Print.
      Energy systems are progressive and revolutionary for their alternative resources, technical developments, demands, effectiveness and environmental effects. The recently published research's goal is to assess and evaluate the systems that are already in operation and those that will be in the future. Energy can be stored as electrical energy such as supercapacitors (SCs) and superconducting magnetic energy storage (SMES) etc., mechanical energy such as pumped hydro energy storage (PHES), compressed air energy storage (CAES) and flywheel energy storage (FES) etc., chemical energy, electrochemical energy such as batteries and fuel cells etc., and thermal energy. Performance of these energy storage systems (ESSs) have been evaluated in terms of energy density, power density, power ratings, capacitance, discharge-time, energy-efficiency, life-time and cycling-times, and costs. Supercapacitors provide highest power density (>10,0000 W/l), while hydrogen fuel cells provide highest energy density (500-3000Wh/l) among other EESs. Batteries also provide high energy density(200-500Wh/l). The energy efficiency is found highest in SMES system (95-98%), and lowest in TES system (30-50%). Moreover, batteries and supercapacitors have the cycle efficiency above 90%. PHES and CAES seem to be the most cost-effective energy storage systems reviewed in this analysis in terms of $/kWh. In addition, power-based capital cost of supercapacitors is lower (100-300$/kW) compared to energy-based capital cost of supercapacitors (300-2000$/kWh). In comparison with power-based capital costs, the energy-based capital cost of batteries is lower, which is 150-400$/kWh for Lead-acid battery, and

      Abstract: Energy & Environment, Ahead of Print.
      Maintenance cost contributes a large portion in total life-cycle cost of offshore wind systems and improves the efficiency of maintenance activities that has emerged as an effective solution in enhancing cost-effectiveness of offshore wind energy. This study proposes a mathematical model to determine the optimal maintenance schedules, by highlighting the deterioration process of offshore wind systems and accounting the optimal vessel routing of maintenance activities, maintenance cost therefore could be shifted to an optimal level. Firstly, reliability of each component is precisely analyzed with respect to the effect of previous maintenance activities. Then, an optimal individual maintenance schedule and a grouping maintenance schedule in daily manner are established based on reliability analysis and opportunity cost consideration. Finally, an optimal maintenance schedule approach accounting vessel routing is apparently presented to optimize the transportation cost of maintenance activities. Numerous influential factors such as system reliability, weather condition, maintenance resource, maintenance duration, production loss cost, and vessel related issues are deliberately examined to enhance the robustness and efficiency of the proposed approach. The experimental results investigating four different scenarios demonstrate that by applying the proposed approach, number of maintenance activity is lowered down, maintenance duration and vessel travelling distance are also significantly reduced in the range of 43.86% - 52.77%, and 52.90% - 58.35%, respectively. Therefore, the economic benefit on maintenance cost could be achieved in an interval of 15.15% - 23.25% by selecting the optimal maintenance schedule.

      Abstract: Energy & Environment, Ahead of Print.
      In the current context of increasing public awareness of the externalities of fossil fuel-based energy consumption, improvement in new technologies for energy-saving systems has become a crucial target to reduce both global warming and air pollution. Being motivated by such a critical matter, this study presents an innovative solar thermal plant based on volumetric expanders as work-producing devices coupled with Scheffler solar receivers as a thermal source. Nowadays, Scheffler receivers are well performing owing to high efficiency of the focal receiver which reduce heat losses. Simultaneously, screw expanders are volumetric machines which are able to convert thermal to mechanical power with acceptable efficiency also by expanding vapor-liquid blends at low operating pressures. The numerical model presented in this study evaluates the energetic benefits of the proposed solar power system for various operating situations. Parametric optimization of this solar power plant is then performed in a broad range of operating conditions: the optimum evaporation temperatures, together with the corresponding maximum global efficiencies, were so defined under various solar radiation intensities. The numerical results attained in this research prove that solar electricity generation systems based on screw expanders coupled with the Scheffler receivers are a promising technology.

      Authors: Muhammad Noshab Hussain, Zaiyang Li, Abdul Sattar, Muhammad Ilyas
      Abstract: Energy & Environment, Ahead of Print.
      This study investigates the impact of renewable energy consumption (REC), nonrenewable energy consumption (NREC), and carbon emissions on economic growth in 133 Belt and Road Initiative (BRI) countries from 1996 to 2020. We divided our sample into four income groups. For empirical estimation, this study employs panel quantile regression (PQR), and fully modified ordinary least squares (FMOLS) estimation techniques. The results confirm that REC have a positive impact on economic growth and NREC has a negative impact on economic growth. A 1% increase in REC and carbon emissions results in an increase in economic growth of 0.108% and 1.085%, respectively. A 1% increase in NREC reduces economic growth by 0.263% in the full sample countries. There are regional differences, although NREC has a positive impact on economic growth in all income groups in the long run. These novel empirical findings will help policymakers design energy policies to fulfill the target of economic growth in BRI countries.

      Authors: Maryam Karami, Hajar Abdshahi
      Abstract: Energy & Environment, Ahead of Print.
      In this study, the transient performance of a qanat source heat pump is investigated using a TRNSYS-MATLAB co-simulator. The water/ethylene glycol-to-air compression heat pump and the helical coil heat exchanger, which is used to inject heat to or to extract heat from the qanat water, are mathematically modeled in matrix laboratory (MATLAB), and then, coupled to transient systems simulation (TRNSYS) model to evaluate the system transient performance and calculate the heating and cooling loads of the case study building. Comparison of the performance of the qanat source heat pump with an air source heat pump showed that the coefficient of performance of the qanat source heat pump is at least 5% and at most 34% higher than that of the air source heat pump. By increasing the flow rate of the working fluid in the helical coil heat exchanger from 2 L/min to 8 L/min, the coefficient of performance of the qanat source heat pump increases at least 12% and at most 34.1%. The maximum increase in energy efficiency ratio and free energy ratio of the system by the similar increase in the flow rate is 46.4% and 24.8%, respectively. The exergy analysis of the qanat source heat pump reveals that the minimum and maximum exergy efficiency of the system is 32% and 85.5%, respectively. The findings also indicate that the most exergy destruction occurs in the condenser in heating mode and in the evaporator in cooling mode.

           — The Mediating and Moderating Effects of the Technology Market

      Authors: Shuhong Wang, Xiaojing Yi
      Abstract: Energy & Environment, Ahead of Print.
      Existing research is ambiguous about the relationship between the financial industry development scale and carbon emission reduction targets. Therefore, using data from 30 provinces and municipalities directly under the central government (excluding Tibet, Hong Kong, Macao, and Taiwan) from 2009–2018, this study divides the reduction targets into emission quantity and intensity to investigate this relationship. Using the improved STIRPAT equation, the pooled OLS and other estimation technique in robustness test, we found that the financial industry development scale is positively related to emission quantity and negatively related to emission intensity. The financial industry development scale inhibits carbon emission intensity through the mediating role of the technology market development degree, which also has a moderating effect on the scale. The study also discusses the regional differences in the scale's impact on carbon emission intensity, its compensation effect on the economic loss caused by carbon emissions, and the positive influence of policy implementation on carbon emission intensity. We provide suggestions to reduce carbon emissions and achieve carbon neutrality.

      Abstract: Energy & Environment, Ahead of Print.
      The most competent and operative use of renewable feedstock is super critical for the production of biodiesel which has increased attention worldwide pertaining to aquatic fern Azolla. Maximizing the biodiesel yield by optimizing the process parameters of the low-frequency ultrasonic energy-assisted transesterification process of Azolla oil is the need of the hour for minimizing the production cost of biodiesel. Response Surface Methodology (RSM) was applied using central composite rotatable design (CCRD) to find the best optimum reaction parameters for this transesterification process. The optimized reaction parameters arrived from the design of experiments were as following: methanol/Azolla oils molar ratio (A)  =  6.49 mole/mole, KOH catalyst concentration (B)  =  1.69 (weight% of oil), reactiion time (C)  =  34.74 min and reaction temperature (D)  =  38.87°C. The best higher theoretical predicted Azolla Fatty Acid Methyl Ester (FAME) yield was Y  =  99.76% which is in well coincidence with the actual yield. The extracted Azolla biodiesel was tested for various fuel properties with standard test procedures and found to be in agreement with various Biodiesel standards and the results are promising in terms of utilizing Azolla oil as an inexhaustible and potentially economical source of biodiesel.

      Abstract: Energy & Environment, Ahead of Print.
      Extensive consumption of fossil fuel has contributed to the worldwide decline of its reserves and detrimental effect on the environment. Therefore, it is essential to explore alternative option of fuel for diesel engine. The main objective of this research article is to optimize vibrations in a single-cylinder variable compression ratio diesel engine driven by Jatropha biodiesel blend. The heterogeneous catalyst (calcium oxide) is used to manufacture of biodiesel from Jatropha curcas oil by a process of transesterification. The optimization technique (Response Surface Methodology) has been employed to optimize root mean square acceleration of vibration by taking load, compression ratio (CR), and fuel injection pressure (FIP) as engine input parameters. Experiments were designed according to central composite design. The amplitude of the frequency domain signals is determined using Fast Fourier Transform and the influence of input parameters has been investigated in the frequency domain analysis of the vibration signatures. The adequacy and significance of the models have been checked by p-value and F value tests. Regression coefficients Adj. R2, R2, Pred. R2 were also found in acceptable range. The experimental outcome reveals that biodiesel yield of 81.6% was obtained at methanol-to-oil molar ratio of 12:1, reaction temperature of 65°C, reaction time of 3 h, and catalyst concentration of 5 wt%. Simultaneously, the model obtained a series of solutions based on the desirability criteria and proposed optimum setting of engine input parameters at a load of 2.59 kg, 17.94 CR, and 268.76 bar FIP for B30 blend. B30 blend generated root mean square acceleration of 4.46 m/s2 at above optimized conditions. A validation trial was conducted and the percentage of error for root mean square acceleration was found to be 2.3356% and 1.3039%, respectively, for B0 and B30 blend.

      Authors: Muthumari Perumal, Dhanalakshmi Jayaraman
      Abstract: Energy & Environment, Ahead of Print.
      In the present work, an experiment for CO2 capture process were performed by absorption using various aqueous solvent blends of amine and ionic liquids. The solvent blends were prepared for various compositions by mixing TetraButylAmmonium Acetate [TBA][OAC] and TetraButylAmmonium Bromide [TBA][Br] ionic liquids with Monoethanolamine (MEA). The obtained results were compared with baseline MEA. It was observed that capture efficiency of CO2, absorption rate of CO2 and CO2 diffusion coefficient of MEA-[TBA][OAC] and MEA-[TBA][Br] solvent blends were comparatively higher than baseline 30%MEA. Moreover, the parameters such as density, viscosity, pH, carbon loading and surface tension of all the solvent blends were measured for before and after absorption process. The carbon loading of solvent blends MEA-[TBA][Br] (0.405 mole of CO2/mole of solvent) and MEA-[TBA][OAC](0.459 mole of CO2/mole of solvent) was slightly lower than baseline MEA (0.494 mole of CO2/mole of solvent). However, the viscosity of MEA-[TBA][Br] blends were remarkably lower than MEA-[TBA][OAC] blend and baseline MEA. This might be an important key factor in solvent recovery process with lesser energy demand for sustainable energy and environment.
