Bioenergy is renewable energy made from renewable harvested material. Biomass is used to supply heat, generate power and fuel transportation. Bioenergy accounts for more than 10 percent of the world's energy consumption, as of 2015 and is used most often in developing countries.
Bioenergy is any renewable energy or fuel obtained from biological sources such as wood, plants and animal waste. In 2012, biofuels accounted for 3.8 billion gallons of total transport fuel consumption. Ethanol is the most significant biofuel in the United States, accounting for 94 percent of biofuel consumption in 2012. Bioenergy can be used directly, as in wood burning, or indirectly, as in liquid ethanol for fuel.
