The effects on global and environmental air quality of pollutants released into the atmosphere from fossil fuels in power plants provide strong arguments for the development of renewable energy resources. Clean, domestic and renewable energy is commonly accepted as the key for future life, not only for Turkey but also for the world. In this regard, the objective of this paper is to present a review of the energy situation, technical and economical potential and utilization of renewables, including hydraulic energy, biomass energy, solar energy, wind energy and geothermal energy, in Turkey and then concerned with greenhouse gas emiss . . .ions status, especially in air pollution, and environmental impacts of renewable energy sources. The renewable energy potential of the country, their present utilization, and greenhouse gas emissions status are evaluated based on the available data. The present paper shows that there is an important potential for renewables in Turkey and making use of renewable energy and energy efficiency resources to provide energy services to the electricity consumers can provide significant environmental benefits for Turkey. © 2007 Elsevier Ltd.

Energy consumption and economic growth in the USA: Evidence from renewable energy

Yildirim E. | Saraç Ş. | Aslan A.

Review | 2012 | Renewable and Sustainable Energy Reviews16 ( 9 ) , pp.6770 - 6774

Recent debates about renewable energy consumption manifest two main expectations. Firstly, renewable energy consumption should contribute to economic growth and secondly, it should not cause damage on environment. This study focuses on the first issue by applying Toda-Yamamoto procedure and bootstrap-corrected causality test for the US since empirical literature criticizes the Toda-Yamamoto test which bases on asymptotic distribution. The models consist of real GDP, employment, investment and kinds of renewable energy consumption. Only one causal relationship was found from biomass-waste-derived energy consumption to real GDP. No ca . . .usal relationship was found between real GDP and all of the other renewable energy kinds - total renewable energy consumption, geothermal energy consumption, hydro-electric energy consumption, biomass energy consumption and biomass-wood-derived energy consumption. That is using of energy from waste cause not only solving the dumping problems but also it contributes to real GDP. For policy purpose, the results of this study suggest that countries should concentrate on energy producing from waste as an alternative energy resource. © 2012 Elsevier Ltd Daha fazlası Daha az

Coal consumption and industrial production nexus in USA: Cointegration with two unknown structural breaks and causality approaches

Yildirim E. | Aslan A. | Ozturk I.

Review | 2012 | Renewable and Sustainable Energy Reviews16 ( 8 ) , pp.6123 - 6127

The paper investigates the causality relationships among industrial production index, coal consumption and employment in industrial sector for the period of 1973:1-2011:10 in USA. After noticing that there are breaks in the regression model, the Hatemi-J test for cointegration is employed to the cases that take into account two possible regime shifts. It is concluded that there is a long run relationship between industrial production and industrial coal consumption with the breaks at 1983:4 and 1998:4. We found a negative relationship between coal consumption and industrial production for the period of 1973:1-1983:4 and positive rel . . .ationship for 1983:5-1998:4 period. For the last period that covers 1983:5-2011:10, the cointegration relationship turned to negative. In addition, the results show that causal relationship between coal consumption and industrial production changes over time. © 2012 Elsevier Ltd Daha fazlası Daha az
