"a  Prior to 1985, excludes commuter rail, automated guideway, urban ferryboat, demand responsive vehicles, and most rural and smaller systems.",,,,,,,,,,,,,,,,,,
"b  For 1992-2001, includes propane, liquid petroleum gas, liquefied natural gas, kerosene, and all other nondiesel fuels except compressed natural gas. 1960 to 1991 data include propane. Series not continuous between 1991 and 1992.",,,,,,,,,,,,,,,,,,

NOTE,,,,,,,,,,,,,,,,,,
"The heat equivalent factors used in joule conversions are: diesel = 38,657,950 joules/liter; electric = 3,600,000 joules/kWh, negating electrical system loses (to include electrical system loses, multiply this conversion factor by approximately three); gasoline = 34,839,537 joules/liter.
