Definition: Bioenergy comes from any fuel that is derived from biomass - recently living organisms or their metabolic byproducts. Biomass can include matter such as cow manure. Unlike other natural resources such as petroleum, coal and nuclear fuels, bioenergy is a renewable energy source.

Like all methods used to generate energy, the combustion of biomass generates pollution as a by-product. However, because the carbon in biofuels was recently extracted from atmospheric carbon dioxide by growing plants, the combustion of a biofuel does not result in a net increase of carbon dioxide in the Earth's atmosphere.
Also Known As: Biofuels
Examples: Agricultural products specifically grown as a source of bioenergy include corn and soybeans, grown primarily in the United States, as well as flaxseed and rapeseed, grown primarily in Europe.

Biodegradable waste such as; straw, timber, manure, sewage, biodegradable waste and food leftovers from industry, agriculture, forestry, and households can also be used to produce bioenergy.
