Bioenergy can be defined as renewable energy from Biomass. Biomass, in turn is biological material derived from living, or recently living organisms. It is material which is directly or indirectly produced by photosynthesis and which is utilised as a feedstock in the manufacture of fuels and substitutes for petrochemical and other energy intensive products. In fact, biomass is unique among the entire renewable energy spectrum since it is the only source of carbon that can be converted into solid, liquid or gaseous fuels. Agricultural and forest residues, municipal solid waste are also included in biomass. Therefore Bioenergy is eventually solar energy and utilizing bioenergy is an idea probably as old as human civilization or existence.
