a Domestic operations only.
b Includes fuel used in air taxi operations, but not commuter operations.
c Prior to 1984, excludes commuter rail, automated guideway, ferryboat, demand responsive vehicles, and most  rural and smaller systems.
d Included in other single-unit 2-axle 6-tire or more truck category.  
e Gasoline and all other nondiesel fuels such as liquified natural gas, methanol, and propane, except compressed natural gas.  

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

NOTES: The following conversion rates were used: Jet fuel = 37,626,700 joules/ litersCompressed natural gas = 38,657,950 joules/ liters
Aviation gasoline = 33,501,698 joules/ litersResidual fuel = 41,723,829 joules/ liters
Automotive gasoline = 34,839,537 joules/ litersResidual fuel = 41,723,829 joules/ liters
Diesel motor fuel = 38,657,950 joules/ litersNatural gas = 38,413,974 joules/ m3
Electricity 1kWh = 3,600,000 joules, negating electrical system loses. To include electrical system loses, multiply this conversion factor by approximately 3.
