aIncludes supplemental gaseous fuels that are commingled with natural gas. jFor 1981 through 1992, includes fuel ethanol blended into motor gasoline that is not included in the motor gasoline column.
bBeginning in 2009, includes biodiesel blended into distillate fuel oil. Beginning in 2011, includes renewable diesel blended into distillate fuel
oil. Beginning in 2021, includes biodiesel and renewable diesel product supplied.
kElectricity imports are included in total primary energy and electric power sector but are not shown separately.
cHydrocarbon gas liquids, include natural gas liquids and refinery olefins. lExpenditures for fuels purchased for electric power generation, included in the expenditure columns for the primary energy sources, are
shown as negative expenditures because they need to be removed from total energy expenditures, to avoid double-counting.
dThrough 2004, includes kerosene-type and naphtha-type jet fuel. Beginning in 2005, includes kerosene-type jet fuel only; naphtha-type jet
fuel is included in "Other Petroleum."
mElectricity sales to ultimate customers reported by electric utilities and, beginning in 1996, other energy service providers.
eBeginning in 1993, includes fuel ethanol blended into motor gasoline. Where shown, R = Revised data and (s) = Value less than 0.05 million dollars.
fIncludes asphalt and road oil, aviation gasoline, kerosene, lubricants, petroleum coke, and the “other petroleum products” category. See
Technical Notes, Section 4.
Where shown, — = No consumption, including cases where adjustments were made. See explanation of adjustments in Section 7 of the
Technical Notes.
gWood, wood-derived fuels, and biomass waste. Prior to 2001, includes non-biomass waste. Note: Expenditure totals may not equal sum of components due to independent rounding.
hThere is a discontinuity in this time series between 1988 and 1989 due to the expanded coverage of the use of wood and biomass waste
beginning in 1989.
