U.S. Dept. of Energy Alternative Fuels Data Center

The DOE Alternative Fuels Data Center (AFDC) provides both introductory and advanced information on all major alternative fuels (biodiesel, electricity, ethanol, hydrogen, natural gas, and propane). It includes a guide to alternative fuel vehicles available for fleets (from refuse collection to public transit), a database of laws and incentives related to alternative fuels (click here to view the Washington list), and a robust set of tools (calculators, interactive maps, and databases). See below for a full list of tools and the links below.
