Biofuels are liquid or gaseous fuels made from biomass. Biomass is simply any organic matter, or dead material, derived from plants or animals. Biomass may include wood, agricultural crops, forestry residues, aquatic crops, municipal waste, or animal waste, amongst other things. Biofuels are similar to fossil fuels in that they are both made from organic matter. However, fossil fuels take millions of years to form, making it a non-renewable energy resource since humans cannot wait around for fossil fuels to form. In contrast, biofuels can be produced in days, weeks, or months, and need not be made by a living organism—they can be produced in an industrial or laboratory setting.

Biofuels are primarily used for transportation, but biofuels can also be used as a source of hydrogen to power fuel cells and produce electricity. Two of the most commonly used biofuels today are ethanol and biodiesel, but there are other biofuels as well.


Ethanol is an alternative fuel made from corn and other plant materials. Over 95% of gasoline used in the United States contains E10 (that is, a blend of 10% ethanol and 90% gasoline) to oxygenate the fuel and reduce air pollution. Ethanol is also available as E85 (that is, a blend of 85% ethanol, 15% gasoline). E85 is typically used in flex-fuel vehicles, which use gasoline, E85, or a blend of both.


Biodiesel is a biodegradable fuel that is produced mainly from vegetable oil, animal fats, or recycled restaurant grease. Biodiesel can act as a substitute for petroleum diesel. B20 (that is, a blend of 20% biodiesel, 80% petroleum diesel) is the most common blend of biodiesel. While this can be used in diesel vehicles, many vehicle manufacturers do not cover biodiesel use in their warranties (more details found at the National Biodiesel Board’s OEM Information page).

See below for embedded maps on stations for biodiesel and ethanol.

Other uses of Biomass

Biopower is the production of electricity or heat from biomass. Technologies include direct combustion, co-firing and anaerobic digestion.

  • Direct combustion is a process that uses conventional boilers and is the primary form of electricity production from biomass. Waste wood products from wood-processing industries is the main source that is burned in the boilers, which in turn, produce steam that spin a turbine. This process activates a generator that produces electricity.
  • Co-firing involves replacing a portion of the petroleum-based fuel in high-efficiency coal-fired boilers with biomass. Co-firing has been successfully demonstrated in most boiler technologies. Co-firing biomass can significantly reduce the sulfur dioxide emissions of coal-fired power plants and is a least-cost renewable energy option for many power producers.
  • Anaerobic digestion, or methane recovery, is a common technology used to convert organic waste to electricity or heat. In anaerobic digestion, organic matter is decomposed by bacteria in the absence of oxygen to produce methane and other byproducts that form a renewable natural gas.
  • Pyrolysis and thermal gasification transforms organic materials into gaseous components.
