=> Biomass energy is generated from organic matter including wood, agricultural waste and cow dung.

=> Biomass energy can only be used for heating and cooking.

=> No special device is required to produce energy from biomass.

Hydroelectricity energy

Both bio-mass and hydro electricity are renewable sources of energy. Biomass is obtained from dead plants and animal wastes whereas hydro electricity is obtained from energy stored in water at some height. Energy from both these sources can be obtained again and again.
