TEXTO: Alternative fuels
Alternative fuels, as defined by the Energy Policy Act of 1992 (EPAct), include ethanol,
natural gas, propane, hydrogen, biodiesel*, electricity, methanol, and p-series fuels. These
fuels are being used worldwide in a variety of vehicle applications. Learn more about how
the EPAct Program works by going to the EPAct Web site. Using these alternative fuels in
vehicles can generally reduce harmful pollutants and exhaust emissions. In addition, most of
these fuels can be domestically produced and derived from renewable sources. Use these
alternative fuels pages to learn more about the fuels, their benefits, and how they can be
used in personal and fleet vehicles. You can compare alternative fuels properties, including
benefits, environmental impacts, and more. To get regional alternative fuel pricing data, go
to the Alternative Fuel Price Report. * Pure biodiesel (B100) is considered an
alternative fuel under EPAct. Lower-level biodiesel blends are not considered alternative
fuels, but covered fleets can earn one EPAct credit for every 450 gallons of B100 purchased
for use in blends of 20% or higher. To learn more, visit the EPAct Alternative Fuels Web
page.

Biodiesel
Biodiesel is a domestically produced, renewable fuel that can be manufactured from vegetable
oils, animal fats, or recycled restaurant greases. Biodiesel is safe, biodegradable, and
reduces serious air pollutants such as particulates, carbon monoxide, hydrocarbons, and air
toxics. Blends of 20% biodiesel with 80% petroleum diesel (B20) can generally be used in
unmodified diesel engines; however, users should consult their OEM and engine warranty
statement. Biodiesel can also be used in its pure form (B100), but it may require certain
engine modifications to avoid maintenance and performance problems and may not be suitable
for wintertime use. Users should consult their engine warranty statement. For more
information on fuel blends of less than 20% biodiesel, please see our site on fuel blends.

Ethanol
Ethanol is an alcohol-based alternative fuel produced by fermenting and distilling starch
crops that have been converted into simple sugars. Feedstocks for this fuel include corn,
barley, and wheat. Ethanol can also be produced from "cellulosic biomass" such as trees and
grasses and is called bioethanol. Ethanol is most commonly used to increase octane and
improve the emissions quality of gasoline.
