aIncludes supplemental gaseous fuels that are commingled with natural gas. iBeginning in 1980, adjusted for the double-counting of supplemental gaseous fuels, which are included in both natural gas and
the other fossil fuels from which they are mostly derived, but should be counted only once in net energy and total. For 1981 through
1992, includes fuel ethanol blended into motor gasoline that is not included in the motor gasoline column. Beginning in 2009, includes
a small amount of wind energy consumed by commercial utility-scale facilities.
bHydrocarbon gas liquids, assumed to be propane only. jIncurred 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.
cBeginning in 1993, includes fuel ethanol blended into motor gasoline. There is a discontinuity in this time series between 2014
and 2015 because of coverage. See Technical Notes, Section 4.
– – = Not applicable. NA = Not available.
dIncludes small amounts of petroleum coke not shown separately. Where shown, R = Revised data and (s) = Physical unit value less than 0.5 or Btu value less than 0.05.
eConventional hydroelectric power. For 1960 through 1989, includes pumped-storage hydroelectricity, which cannot be separately
identified.
Notes: Totals may not equal sum of components due to independent rounding. · The commercial sector includes commercial
combined-heat-and-power (CHP) and commercial electricity-only plants. · The continuity of these data series estimates may be
affected by changing data sources and estimation methodologies. See the Technical Notes for each type of energy.
fThere is a discontinuity in this time series between 1988 and 1989 due to the expanded coverage of renewable energy sources
beginning in 1989.

gWood, wood-derived fuels, and biomass waste. Prior to 2001, includes non-biomass waste. Sources: Data sources, estimation procedures, and assumptions are described in the Technical Notes.
hSolar thermal and photovoltaic energy. Excludes a small amount of solar thermal energy consumed as heat that is included in the
residential sector.
