The electricity necessities of the world including India are elevated at disturbing rate and the power demand has been increasing. The fossil fuels (i.e., coal, petroleum and natural gas) and other conventional resources, presently used for generation of electrical energy. It is not sufficient or suitable to keep Generation with ever increasing demand of the electrical energy of the world. The generation of electrical power by cold based steam power plant and nuclear power plants causes pollution, which is likely to be more harmful in future due to large generating capacity on one side and it Became tough Because greater awareness of the people in this respect. This project give idea about non- conventional Energy sources and why we are going for that non-conventional energy sources. The proper uses of solar energy and its different application which are using at home defence sector, marines, remote area etc.
