Question

compare and contrast bio mass and hydroelrtricity as sores of enery

Answer 1

Explanation:

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.

Answer 2

Explanation:

Hydroelectricity is generated using the kinetic energy from moving water, while the energy from biomass is generated by decomposition of farm waste. Since biomass is composed of organic compounds so energy from biomass results in air pollution. Hydroelectricity, on the other hand, is pollution free.
