All the biomass has been produced be the help of solar energy reaching the earth. Only 0.2% of energy is trapped in biomass. The process of conversion of biomass into energy is called bioconversion. Bio energy is defferentiable into animal energy and biofuels. Animal energy is a bio energy available for performing work through human muscle power and draught animal power. Biofuels are combustible materials of biological origin which can be employed to produce heat in other forms of energy either directly or through chemical formed from them. Biofuels consists of wood, organic wastes, energy cropping and petroleum plants.
