Write a brief note on conventional and non-conventional sources of energy.
Solution:
Conventional Sources of Energy:
Conventional source of energy have been used since the early times. Coal, Petroleum, natural gas, hydro-electricity, thermal power are the source of energy. All conventional sources of energy except hydro-electricity are exhaustible. These source cause environmental pollution. These source require huge capital.
Non-Conventional Sources of Energy:
Non- conventional source of energy have came into the use only recently. Wind energy, solar energy, tidal energy, geothermal, biogas are example of these source of energy. Most of the non- conventional sources of energy are inexhaustible. These sources do not cause environmental pollution. Small amount of money is sufficient to have these sources.
