Gas and electricity generated from organic matter is bioenergy. It ranges from timber, plants to food wastes and agricultural residues. It converts transport fuels generated from organic substances. Feedstocks can be particularly grown for their energy. Bioenergy is obtained from biomass. Usage ranges from cooling, heating, electricity to transport. It is used in liquid form, namely biofuels, in gaseous states such as biogas or in solid forms as seen while burning wood for energy.
