U.S. Government Energy Consumption by Agency and Source, Fiscal Years

(Trillion Btu)

Dataset Excel: 

Totals may not equal sum of components due to independent rounding.

These data include energy consumed at foreign installations and in foreign operations, including aviation and ocean bunkering, primarily by the U.S. Department of Defense. U.S. Government energy use for electricity generation and uranium enrichment is excluded. 

Data in this table are prepared using the following conversion factors:

Electricity = 3,412 Btu/kilowatt-hour.

Purchased steam = 1,000 Btu/pound.

Coal = 24.580 million Btu/short ton.

Natural gas = 1,031 Btu/cubic foot.

Aviation gasoline: 5.250 million Btu/barrel.

Fuel oil = 5.8254 million Btu/barrel.

Jet fuel = 5.460 million Btu/barrel. 

Liquefied petroleum gas = 4.011 million Btu/barrel.

Motor gasoline = 5.250 million Btu/barrel.


KEY: Btu = British thermal unit; GSA = General Services Administration; NASA = National Aeronautics and Space Administration; N = data do not exist; R = revised.

a For 1975, the U.S. Government’s fiscal year was July 1 through June 30. Beginning in 1977, the U.S. Government’s fiscal year is October 1 through September 30. 

b Includes all U.S. government agencies not separately displayed. See for agency list.

c Natural gas, plus a small amount of supplemental gaseous fuels.

d Distillate fuel oil, including diesel fuel; and residual fuel oil, including Navy.

e Includes E10 (a mixture of 10% ethanol and 90% motor gasoline) and E15 (amixture of 15% ethanol and 85% motor gasoline).

f Other types of fuel used in vehicles and equipment. Primarily includes alternative fuels such as compressed natural gas (CNG); liquefied natural gas (LNG); E85 (a mixture of 85% ethanol and 5% motor gasoline); B20 (a mixture of 20% biodiesel and 80% diesel fuel); B100 (100% biodiesel); hydrogen; and methanol.

g Other types of energy used in facilities. Primarily includes chilled water, but also includes small amounts of renewable energy such as wood and solar thermal.
