The Effect of Electricity Supply on Industrial Production Within The Nigerian Economy (1970 – 2010)
- Authors: NWANKWO; OLIVIA CHIGOZIE|NJOGO, BIBIANA OLUCHUKWU
  Abstract: There are apparently links between a sustained economic growth and electricity in an economy. In this study, we employ a multiple regression model to examine the effect of electricity supply on economic development and likewise the effect of electricity supply on industrial development. The result of the regression shows that, the electricity (ELEC), Gross fixed capital formation (GFCF), industrial production (INDU) variables and population have the positive sign. That is, they are positively related to RGDP Per capita. Turning to the Industrial production expenditure model, the electricity generation expenditure, gross fixed capital formation and population variables are positively related to GDP Percapita. As a way of facilitating the economic development, it is recommended that issues relating to electricity production and industrial development should be given priorities particularly in the budget scheme and because of this, substantial amount should be allocated to the electricity sector to be able to fix the state of electricity permanently in a good shape. Keywords: Electricity supply, Industrial production, Economic Growth..

Renewable Energy and Sustainable Food Security in Nigeria
- Authors: N. Tijjani|A. I. Saddik|I. Muhammad|A.M. Lawal|S.A. Maje
  Abstract: Renewable energy sources are becoming an increasingly important alternative source of energy in the agricultural sector. The use of renewable energy will reduce the use of fossil fuels, thereby minimizing the emission of green house gases. Increased use of renewable sources of energy especially in the agricultural sector will enhance the sustainability of food security in Nigeria and the quality of the environment. The use of renewable energy sources in the agricultural sector will also lead to environmentally friendly, sustainable and viable sources of energy to reduce the dependency on depleting fossil fuels. Increasing attention is being focused on the installation and usage of renewable energy sources in the agricultural sector in several countries of the world purposely to contribute to global reduction in greenhouse gas emissions and sustainable food security. This paper attempt to explain the role of renewable energy sources in agricultural sector as a means of enhancing sustainable food security in the country and presents the existing technologies, policies and emerging opportunities in renewable energy application in the agricultural sector. Keyword: Available incentive, Energy policy, Renewable energy, Sustainable food security.

Performance Assessment of the First Residential Grid-Tie PV System in Jordan
- Authors: Ibrahim M. Al-Adwan
  Abstract: In Jordan, exploration of energy sources has been initiated due to a sever power shortage. In this paper, a grid-connected photovoltaic solar system to supply a residence in Amman is implemented. The operational performance results of performance ratios are presented to study the effectiveness of the photovoltaic system without battery storage. Online monitoring is employed and real time data is collected to study the feasibility of grid-tied photovoltaic system. Experimental findings show the high efficiency and stability of the grid-connected photovoltaic system. Also the control unit shows a good performance of improving a flexible regulation of power factor using maximum power point tracking. Keywords: grid-tie photovoltaic solar system; maximum power point tracking; single-stage inverter.

Spray Behavior Comparison in Diesel Engine with Biodiesel as Fuel
- Authors: Gautam Kumar|Anoop Kumar
  Abstract: Sprays are among the very main factors of mixture formation and combustion quality in almost every internal combustion engine. In present study spray penetration depth of various spray models are compared with the variation in injected pressure. The Mahua oil is taken as a biodiesel is the present study and Hiroyasu model can be used for predicting the performance of Mahua biodiesel. Hiroyasu model is found best model among all models studied for high injected pressure. The penetration depth difference of Hiroyasu and Arregle models increased sharply with lapse of time. Keywords: biodiesel; penetration depth; injection pressure; spray

Comparative Evaluation of Qualitative and Quantitative Biogas Production Potential of Oil Palm Fronds and Co-digestion with Cow Dung
- Authors: Ossai; Ochonogor Samuel
  Abstract: Investigation to determine the qualitative and quantitative biogas production potential of oil palm fronds (PF-alone) and its blend with cow dung (PF:CD) in a pre-determined ratio 1:1 was evaluated. Two 50 L capacity plastic jerry-can re-designed and retrofitted as a biodegesters were used for the digestion. The wastes were mixed in the ratio of 2:1 (water to waste) and subjected to anaerobic digestion at mesophilic temperature range of 270C to 390C. Results obtained after a retention period of 27 days indicated an optimization in gas production by co-digesting oil palm fronds with cow dung (PF:CD) with cumulative biogas yields of 187.4L as against 116L for PF-alone. Flammability of produced biogas revealed a time lag of 5 days for PF:CD with sustained flammable gas production throughout the retention period while time lag for PF-alone was 2 days with un-sustained flammability. Peak biogas production was recorded for both digesters at pH of 6.6-to-6.9. Co-digestion of abundantly available animals and plants residues is hereby recommended as an environmentally sound, economically viable and socially acceptable solution to the current energy and waste management quagmire. Keywords: biogas, energy, anaerobic digestion, oil palm fronds, flammability
