aBeginning in 2008, data are no longer collected and are assumed to be zero. hIncurred 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.
bIncludes supplemental gaseous fuels that are commingled with natural gas. – – = Not applicable. NA = Not available.
cHydrocarbon gas liquids, assumed to be propane only. Where shown, R = Revised data and (s) = Physical unit value less than 0.5 or Btu value less than 0.05.
dWood and wood-derived fuels. Notes: Totals may not equal sum of components due to independent rounding. · 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.
eThere 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 https://www.eia.gov/state/seds/seds-data-complete.php.
fSolar thermal and photovoltaic energy. Includes solar thermal energy consumed as heat by the commercial and industrial
sectors.
Sources: Data sources, estimation procedures, and assumptions are described in the Technical Notes.
gBeginning 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.
