Authors:Poul Alberg Østergaard, Rasmus Magni Johannsen Pages: 1 - 2 Abstract: This 36th volume of the International Journal of Sustainable Energy Planning and Management starts at the global scale with a survey of the economy of the oil industry. Limitations of single-sector analyses of Chile is the focal point of a commentary on a previously published study in the journal Energies. The authors of the commentary find that limitations in literature survey, methodology, and data result in a significant underestimation of, e.g., the potential for photo voltaics. The potential for hydro power is affected by changes in water flows as analysed by Melo, which brings some level concern as hydro power is a key element in Brazil’s renewable energy exploitation effort. Lasty, Dall-Orsoletta et al. look into system dynamic models and whether they include social aspects in the modelling. This is only found in a minority of system dynamic models.

Authors:Juan Carlos Osorio-Aravena, Jannik Haas, Arman Aghahosseini, Christian Breyer Pages: 11 - 18 Abstract: This paper is a commentary on ‘Decarbonizing the Chilean Electric Power System: A Prospective Analysis of Alternative Carbon Emissions Policies’ –an article published by Babonneau et al. in the Energies Journal. On the one hand, our aim is to point out and discuss some issues detected in the article regarding the literature review, modelling methods and cost assumptions, and, on the other hand, to provide suggestions about the use of state-of-the-art methods in the field, transparent and updated cost assumptions, key technologies to consider, and the importance of designing 100% renewable multi-energy systems. Furthermore, we end by highlighting suggestions that are key to modelling 100% renewable energy systems in the scientific context to contribute to expanding the knowledge in the field.

Authors:Leonardo Barrouin Melo, Antonella Lombardi Costa, Fidellis Estanislau, Carlos Eduardo Velasquez, Angela Fortini, Gustavo Nikolaus Pinto Moura Pages: 19 - 32 Abstract: Competition for water use, population growth, territorial expansion for housing, the finitude of fossil fuels, climate change, and the lack of consistent and continuous energy planning are some of the existing problems related to planning and monitoring energy supply systems. This work presents an integrated analysis of the water-energy-emissions nexus using two computational models simultaneously in order to consider a case study for the modeling of hydropower plants. The main results include the reduction in hydropower generation at the end of the study horizon (2019 – 2049) between (-16.8%) and (-7.8%) considering water restriction scenarios. Final electricity demand, in the reference scenario, increased 40.8% and, in alternative scenarios, there was an increase between 63.6% and 89.5% when reductions in the rainfall regime were considered.

Authors:Alaize Dall-Orsoletta, Mauricio Uriona-Maldonado , Géremi Dranka, Paula Ferreira Pages: 33 - 52 Abstract: The problem of techno-economic approaches to evaluating energy transition pathways has been constantly reported in the literature. Existing research recognises the critical role played by social aspects in energy systems models. System dynamics (SD) has been pointed out among modelling techniques as a suitable tool to evaluate the interdisciplinary nature of energy transitions. This paper explores how energy system-related SD models have incorporated social aspects through a literature review. Models were assessed based on their geographical resolution, time horizon, methodological approach, and main themes: supply-demand, energy-economy-environment (3E), energy-transport, water-energy-food (WEF) nexus, and consumer-centric and socio-political dynamics. Social aspects considered include behaviour and lifestyle changes, social acceptance, willingness to participate, socio-economic measures, among others. As expected, the representation of social aspects was not standard among the papers analysed. Socio-economic aspects were most commonly included in supply-demand and 3E models. Energy-transport and WEF models mainly incorporated changes in travel and consumption habits, respectively. The last theme had a more diverse approach to social aspects that deserves further attention, especially for energy access and justice issues. Other research lines include modelling approaches combination, enhanced participatory and transparent processes during model development, and use of SD models in policy-aiding and stakeholders’ information processes.

Authors:Aviel Verbruggen First page: 3 Abstract: Physical oil and gas abundance, turned in market scarcity, do prices of oil and gas spike and cashed rents mount. For the years 1970-2020, the rents from crude oil and natural gas sales are expressed in US$-2020, revealing the magnitude and volatility of the money flows. Peak rents coincide with turmoil implying particular oil & gas exporting countries. Oil & gas geopolitics metamorphosed from conquering oil deposits to precluding oil & gas exports by ‘hostile’ nations. Such preclusions turn physical abundance in market scarcity, boosting oil & gas prices and rents (also called royalties, windfall, excess profits). Rent skimming is also a part of the 2022 Ukraine war. Climate change mitigation intensifies geopolitical efforts to curtail the exports of ‘hostile’ nations.
