ABSTRACT: The electricity requirements of the world including India are increasing at alarming rate and the power demand has been running ahead of supply. It is also now widely recognized that the fossil fuels (i.e., coal, petroleum and natural gas) and 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 use non conventional sources of energy for power generation, because they are free of cost and doesn’t produce any pollution at all. The other non-conventional methods of power generation may be such as solar cells, fuel cells, thermo-electric generator, solar power generation, wind power generation, geo-thermal energy generation, tidal power generation etc. The path for sustainability in the next millennium is the low energy path through wise use of energy. Energy conservation and energy efficiency measures would certainly result in meeting the Energy demand with as little as half the primary supply at current levels. This requires profound structural changes in Socio-economic and institutional arrangements. Environmentally Sound, technically and economically viable energy pathways will sustain human progress in the long term future giving a fair and equitable share of the underprivileged and poor of the developing Countries. This paper elucidates about Different Energy sources, why we are going for non-conventional energy sources, Different non-conventional energy sources & comparison between them & how they can support our future.
