KEY: Btu = British thermal unit; N = data do not exist; P = preliminary; R = revised; U = data are unavailable.

NOTES: Certificated carriers are domestic operations only. General aviation includes fuel used in air taxi operations, but not commuter operations.
The following conversion rates were used:
Jet fuel = 135,000 Btu/gallon
Compressed natural gas = 138,700 Btu/gallon
Aviation gasoline = 120,200 Btu/gallon
Distillate fuel = 138,700 Btu/gallon
Automotive gasoline = 125,000 Btu/gallon
Residual fuel = 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 foactor by 3.
