Table 4-6M: Energy Consumption by Mode of Transportation(Petajoules)
KEY: N = data do not exist; R = revised; U = data are unavailable. 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 Gasoline and all other nondiesel fuels such as liquefied natural gas, methanol, and propane, except compressed natural gas. e Included in other single-unit 2-axle 6-tire or more truck category. NOTES The following conversion rates were used: Jet fuel = 37,626,700 joules/liter Compressed natural gas = 38,657,950 joules/liter Aviation gasoline = 33,501,698 joules/liter Distillate fuel = 38,655,829 joules/liter Automotive gasoline = 34,839,537 joules/liter Residual fuel = 41,723,829 joules/liter Diesel motor fuel = 38,657,950 joules/liter Natural gas = 38,413,974 joules/m3 Electricity 1kWh = 3,600,000 joules/kWh, negating electrical system losses. To include approximate electrical system losses, multiply this conversion factor by 3. 1.055056 petajoules = 1 trillion British thermal unit (Btu).
