a Prior to 1985, excludes commuter rail, automated guideway, urban ferryboat, demand responsive vehicles, and most rural and smaller systems.
b For 1992-96, includes propane, liquid petroleum gas, liquefied natural gas, kerosene, and all other nondiesel fuels except compressed natural gas. From 1960 to 1991, includes propane. Series not contiguous between 1991 and 1992.

KEY: kWh = kilowatt hour; N = data do not exist; P = preliminary; R = revised.

NOTE: To convert to joules, use the following energy conversion factors: 1kWh=3,600,000 joules, negating electrical system loses. To include electrical system loses, multiply this conversion factor by approximately three;  1 liter of gasoline = 34,839,537 joules; 1 liter of diesel fuel=38,657,950 joules. APTA changed from American Public Transit Association to American Public Transportation Association in January 2000. The APTA Transit Fact Book changed to the Public Transportation Fact Book in March 2000.
