Tag: non-conventional sources of energy

 Natural resources like wind, tides, solar, biomass, etc generate energy which is known as "Non-conventional resources“. These are pollution free ,renewable,inexhaustible  and hence we can use these to produce a clean form of energy without any wastage.

Lignite, natural gas, and coal are all fossil fuels formed over millions of years. The Sun is a primary, renewable, and non-fossil source of energy, making it the odd one out.
