KEY: kWh = kilowatt hour; N = data do not exist;
P = preliminary; R = revised.
a Prior to 1984, excludes commuter rail,
automated guideway, urban ferryboat, demand responsive vehicles, and most
rural and smaller systems.
b 1992 to
2003 data include 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.
NOTES
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.
1.609344 kilometers = 1 mile.
3.785412 liters = 1 gallon.
