KEY: Btu = British thermal unit, U = data are unavailable.
NOTES: Certificated carriers are domestic operations only. General aviation includes fuel used in air taxi operations, but not commuter operations. 2010 General aviation data are estimated.
Highway data for 2007-09 were calculated using a new methodology developed by FHWA. Data for these years are based on new categories and are not comparable to previous years. The new category Light duty vehicle, short wheel base includes passenger cars, light trucks, vans and sport utility vehicles with a wheelbase equal to or less than 121 inches. The new category Light duty vehicle, long wheel base includes large passenger cars, vans, pickup trucks, and sport/utility vehicles with wheelbases larger than 121 inches.
The following conversion rates were used:
Jet fuel = 135,000 Btu/gallon
Aviation gasoline = 120,200 Btu/gallon
Compressed natural gas = 138,700 Btu/gallon
Distillate fuel = 138,700 Btu/gallon
Automotive gasoline = 125,000 Btu/gallon
Residual fuel oil = 149,700 Btu/gallon
Diesel motor fuel = 138,700 Btu/gallon
Natural gas = 1,031 Btu/ft3
Electricity 1kWh = 3,412 Btu, negating electrical system losses. To include approximate electrical system losses, multiply this conversion factor by 3.
