Biomass energy includes energy generated from wood and wood waste, biogas from landfill waste, sewage and industrial wastewater, animal waste, and municipal solid waste (household garbage like paper, cardboard, food waste, plastics, glass and metals).

Biomass was the largest source of energy in the United States up until its peak in 1870, when 70% of energy came from wood. There was such a demand for wood in Britain in the late 1600s that there was a timber shortage.1 Coal, and later petroleum, quickly replaced wood as the leading source of energy.2 However, biomass can also be converted directly into a liquid, called biofuels, such as bioethanol (ethanol) and biodiesel. The Clean Air Act mandates that oil refineries incorporate renewable fuels into their gasoline and diesel products.3

While an advantage to biomass is that it is a renewable energy, concerns over reforestation, rate of replacement, and the debate on whether or not biomass energy is carbon neutral make it a concern for environmentalists and clean energy advocates.4
