aIncludes supplemental gaseous fuels that are commingled with natural gas. jElectricity sales to ultimate customers reported by electric utilities and, beginning in 1996, other energy service
providers.
bHydrocarbon gas liquids, include natural gas liquids and refinery olefins. kBeginning 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 End Use 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 industrial utility-scale facilities.
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.
lIncurred 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.
dIncludes asphalt and road oil, kerosene, lubricants, petroleum coke, and the “other petroleum products” category. See
Technical Notes, Section 4.
kWh = Kilowatthours. – – = Not applicable. NA = Not available.
eConventional hydroelectric power. For 1960 through 1989, includes hydroelectric pumped-storage, which cannot be
separately identified.
Where shown, R = Revised data and (s) = Physical unit value less than 0.5 or Btu value less than 0.05.
fThere is a discontinuity in this time series between 1988 and 1989 due to the expanded coverage of renewable
energy sources beginning in 1989.
Notes: Totals may not equal sum of components due to independent rounding. · The industrial sector includes
industrial combined-heat-and-power (CHP) and industrial electricity-only plants. · 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.
gWood, wood-derived fuels, and biomass waste. Prior to 2001, includes non-biomass waste. Web Page: All data are available at https://www.eia.gov/state/seds/seds-data-complete.php.
hLosses and co-products from the production of biodiesel and fuel ethanol. Data Source: U.S. Energy Information Administration, State Energy Data System. See Technical Notes.

iSolar thermal and photovoltaic energy. Excludes a small amount of solar thermal energy consumed as heat that is
included in the residential sector.
