KEY: Btu = British thermal unit; E = estimated; R = revised; P = preliminary.

a Sum of primary consumption, electricity, and electrical system energy losses categories.

b Sum of coal, natural gas, and petroleum categories.

c Consumed in the operation of pipelines, primarily in compressors, and small amounts consumed as vehicle fuel.

d 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.

e From 1980, small amounts of coal consumed for transportation are included in industrial sector consumption.

f Incurred in the generation, transmission, and distribution of electricity plus plant use and unaccounted for electrical system energy losses.

g There is a discontinuity in this time series between 1998 and 1999; beginning in 1999, nonutility consumption of fossil fuels is included in electric power sector consumption and the calculation of electrical system energy losses.

NOTES: Energy consumption (all sectors) differs from totals in table 4-2 for 1990 and subsequent years.

Table 4-2 includes primary energy consumption only.
