Alternative Fuels

The Energy Policy Act of 1992 defines alternative fuels as methanol, denatured ethanol and other alcohol; mixtures containing 85 percent or more (but not less than 70 percent as determined by the Secretary of Energy by rule to provide for requirements relating to cold start, safety or vehicle functions) by volume of methanol, denatured ethanol and other alcohols with gasoline or other fuels. Includes compressed natural gas, liquid petroleum gas, hydrogen, coal-derived liquid fuels, fuels other than alcohols derived from biological materials, electricity or any other fuel that the Secretary of Energy determines by rule is substantially not petroleum and would yield substantial energy security and environmental benefits.
