Answer :

Types of energy Source 

Primary energy source is an energy form found in nature that has not been subjected to any conversion or transformation process. The primary energy sources are derived from: the sun, the earth’s heat, the wind, water (rivers, lakes, tides, and oceans), fossil fuels - coal, oil, and natural gas, biomass, and radioactive minerals.

Secondary energy source Secondary energy refers to the more convenient forms of energy which are transformed from other, primary, energy sources through energy conversion processes. Examples are electricity, which is transformed from primary sources such as coal, raw oil, fuel oil, natural gas, wind, sun, streaming water, nuclear power, gasoline etc.

Conventional Energy sources: These sources are exhaustible after use. e.g Coal, crude oil, Gas

Non-Conventional energy sources: These sources can renew again and again. e.g Solar, Wind, Biomass, Hydro
