aTransportation use of natural gas to operate pipelines and, since 1990, also includes vehicle fuel. hFor 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.
iIncurred in the generation, transmission, and distribution of electricity plus plant use and unaccounted for
electrical system energy losses. Pre-1990 estimates are not comparable to those for later years. See Section 6 of
Technical Notes for an explanation of changes in methodology.
cHydrocarbon gas liquids, assumed to be propane only. – – = Not applicable.
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 "Industrial sector, Other Petroleum."
Where shown, R = Revised data and (s) = Physical unit value less than 0.5 or Btu value less than 0.05.
eBeginning in 1993, includes fuel ethanol blended into motor gasoline. Notes: Totals may not equal sum of components due to independent rounding. · The continuity of these data
series estimates may be affected by the changing data sources and estimation methodologies. See the Technical
Notes for each type of energy.
fElectricity sales to ultimate customers reported by electric utilities and, beginning in 1996, other energy service
providers. Sales to public railroads and railway systems only. Excludes electric vehicles.

gThere is a discontinuity in this time series between 1980 and 1981 due to the expanded coverage of fuel
ethanol beginning in 1981.
