BIOMASS ENERGY OVERVIEW
In 2010, biomass energy production contributed 4.3 quadrillion Btu (British thermal units) of energy to the 75 quadrillion Btu of energy produced in the United States or about 5.7% of total energy production. Since a substantial portion of U.S. energy is imported, the more commonly quoted figure is that biomass consumption amounted to 4.3 quadrillion Btu of energy of the 98 quadrillion Btu of energy consumed in the United States in 2010 or about 4.4%. At present,…Read more. http://cta.ornl.gov/bedb/introduction/Biomass_Energy_Overview.shtml
A variety of fuels can be produced from biomass resources including liquid fuels, such as, ethanol, methanol, biodiesel, Fischer-Tropsch diesel and gasoline, and gaseous fuels, such as hydrogen and methane. Biofuels are primarily used to fuel vehicles, but can also fuel engines or fuel cells for electricity generation….Learn more http://cta.ornl.gov/bedb/biofuels/Biofuels_Overview.shtml
As a petroleum refinery uses petroleum as the major input and processes it into many different products, a biorefinery uses biomass as the major input and processes it into many different products. Wet-mill and dry-mill corn processing plants and pulp and paper mills can be categorized as biorefineries since they produce multiple products from biomass. Ethanol production facilities produce ethanol and other products from the sugar and starch components of biomass. As of August 2011,…Learn more.
