2.2. Non Conventional Energy Sources

With increasing demand for energy and with fast depleting conventional source of energy such as coal, petroleum and natural gas, the non-conventional sources of energy such as energy from sun, wind, bio-mass, tidal , geo-thermal energy are gaining importance. This energy is abundant, pollution-free, renewable and eco-friendly. Besides, it can be supplied evenly to urban, rural and even remote areas. The non-conventional energy sources are cost intensive at the initial stages but will provide more sustained, eco-friendly cheaper energy after the initial cost is taken care of.
