aNatural gas as it is consumed; includes supplemental gaseous fuels that are commingled with natural gas. hSmall amounts of solar thermal and photovoltaic energy consumed in the commercial sector are included in residential
consumption. From 1981 through 1992, includes fuel ethanol blended into motor gasoline that is not included in the motor
gasoline column. Beginning 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.
bLiquefied petroleum gases. 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.
cBeginning in 1993, includes fuel ethanol blended into motor gasoline. – – = 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.		 Web Page: All data are available at http://www.eia.gov/state/seds/seds-data-complete.cfm.
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.
