Abstract: The electricity requirements of the world including India are increasing at alarming rate and the power demand has been running ahead of supply. Other conventional resources, presently being used for generation of electrical energy, may not be either sufficient or suitable to keep pace with ever increasing demand of the electrical energy of the world. Also generation of electrical power by cold based steam power plant or nuclear power plants causes pollution, which is likely to be more acute in future due to large generating capacity on one side and greater awareness of the people in this respect. The recent severe energy crisis has forced the world to develop new and alternative methods of power generation, which could not be adopted so far due to various reasons. The non-conventional methods of power generation may be such as solar energy, wind power, hydro-electric energy, biomass, hydrogen and fuel cells, geo-thermal power etc. This paper elucidates about different non-conventional energy sources like solar, wind, hydroelectric, biomass, geothermal etc,
