Bioenergy is renewable energy produced by living organisms from biological origin. Biomass is any organic matter which has deposited sunlight in the form of chemical energy. As a fuel it may comprise wood, straw, wood waste, sugarcane, manure, and many other by-products from different agricultural engineering processes. In its wider sense it includes biomass, the biological matter utilized as a biofuel, as well as the social, scientific, economic and technical fields related with utilizing biological sources for energy. This is a common misbelief, as bioenergy is the energy cultivated from the biomass, as the biomass is the fuel and the bioenergy is the energy stored in the fuel.
