Hello candidate,

There are several energy sources of India which are non polluting in nature such as wind energy, solar energy, tidal energy, geothermal energy and various others and most of these energy sources do not have a harmful effect on the environment by releasing greenhouse gases. The most widely used source is hydroelectric power, which currently supplies some 6.6% of the world's energy needs. Other non-polluting sources are solar energy, tidal energy, wave energy and wind energy.

Hope you found it helpful.
