Energy Resources
Energy can be generated from fuel minerals like coal, petroleum, natural gas, uranium and from electricity. Energy resources can be classified as conventional and nonconventional sources.
CONVENTIONAL SOURCES:
Firewood, cattle dung cake, coal, petroleum, natural gas and electricity (both hydel and thermal).
NON-CONVENTIONAL SOURCES:
Solar, wind, tidal, geothermal, biogas and atomic energy. Firewood and cattle dung cake are most common in rural India. According to one estimate more than 70 per cent energy requirement in rural households is met by these two ; continuation of these is increasingly becoming difficult due to decreasing forest area. Moreover, using dung cake too is being discouraged because it consumes most valuable manure which could be used in agriculture.
