KEY: Btu = British thermal unit

NOTES: Total transportation consumption is the sum of primary consumption, electricity, and electrical system energy losses categories. Total primary consumption is the sum of natural gas, and petroleum categories. Natural gas is consumed in the operation of pipelines, primarily in compressors, and small amounts consumed as vehicle fuel.
Petroleum products
includes most nonutility use of fossil fuels to produce electricity and small amounts (about 0.1 quadrillion Btu per year since 1990) of renewable energy in the form of ethanol blended into motor gasoline.
Electrical system energy losses
are incurred in the generation, transmission, and distribution of electricity plus plant use and unaccounted for electrical system energy losses.
