abstract="The Energy Policy Act of 1992 required state and federal agencies to buy alternative fuel vehicles (AFVs) as part of their transit and other fleets. Even though cities and counties are exempt under the Act from having to purchase AFVs, many have voluntarily elected to do so to improve their air quality and lessen their dependence on petroleum-based fuels. Communities considering purchasing AFVs, which are powered by natural gas, ethanol, biodiesel, propane, electricity, hydrogen, or a combination of gasoline and electricity--can look to data from a wide range of fleet tests conducted by transit agencies, school districts, and other public works entities. This article gives an overview of the use of AFVs based on case examples from around the U.S.<p />",
