Alternative Fuel Vehicles (Archives, 2003-2017)

This database contains the number of alternative-fuel vehicles and estimated consumption for all states by weight class, vehicles type, engine configuration, and user group.  Fuel consumed is expressed in thousands of gasoline equivalent gallons (geg).  Data are available in some cases for some states that are not specified.
