Global renewable electricity potential

Abstract

Due to the concern in the rising of global warming and in the dwindling supply of fossil fuels, global exploitation of renewable energy technologies is increasing spontaneously. Most of the countries in the world are blessed with two or more renewable energy sources (RES) and hence have formulated policies to boost the utilization of RES for their electricity production. In order to further develop the RES based electricity production, an assessment of renewable electricity potential is essential for further research and development related works in the field of renewable energy technologies. Recent developments in installation capacities of hydro, wind, solar, biomass and geothermal based electricity generation are discussed in this paper. From the analysis it is clear that significant amount of fuel cost and pollutants emission can be reduced by the increased use of RES based electrical power production technologies.
