Information and Resources

Biofuel is liquid fuel derived from biomass. The two most common types of biofuel are biodiesel and ethanol.


Biodiesel is a popular clean-burning biofuel that is made from vegetable oils, animal fats and tallow, and recycled cooking oils.

Learn more about biodiesel’s production and use by means of the Biodiesel Fact Sheet.



Ethanol can be made from biomass materials containing sugars, starches, or cellulose (starch and cellulose are more complex forms of sugar). Examples of cellulose are corn stalks, trees and grasses. Although pilot plants and a few government-subsidized plants exist, currently there are no commercial plants producing ethanol from cellulose. Further research is being conducted to improve the economic viability of converting cellulose materials into ethanol.

Other biofuels

In addition to biodiesel and ethanol, there are other biofuels that can be made such as biobutanol and P-Series.

  • NREL BioEnergy Atlas

    Built into Google Maps, BioEnergy Atlas includes two interactive maps, BioPower and BioFuels. These maps allow you to compare and analyze biomass feedstocks, biopower and biofuels data from the U.S. Department of Energy (DOE), U.S. Environmental Protection Agency (EPA), and the U.S. Department of Agriculture. Learn more>>

  • Bioenergy KDF

    Similar to the BioEnergy Atlas, this tool supported by the Department of Energy incorporates data shared by government and the bioenergy industry.  The KDF examines the economic and environmental impacts of development options for biomass feedstock production, biorefineries, and related infrastructure.
