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 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.

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

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.
