aNatural gas as it is consumed; includes supplemental gaseous fuels that are commingled with natural gas. hElectricity traded with Canada and Mexico. Btu value calculated by converting net imports in kilowatthours by
3,412 Btu per kilowatthour.
bPrior to 1980, based on oil used in internal combustion and gas turbine engine plants. For 1980 through 2000,
distillate fuel oil includes fuel oil Nos. 1 and 2, and small amounts of kerosene and jet fuel.
i 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.
cPrior to 1980, based on oil used in steam plants. For 1980 through 2000, residual fuel oil includes fuel oil Nos. 4,
5, and 6.
– – = Not applicable. NA = Not available.
dConventional hydroelectric power. For 1960 through 1989, includes pumped-storage hydroelectricity, which
cannot be separately identified.
Where shown, R = Revised data and (s) = Physical unit value less than +0.5 and greater than -0.5 or Btu value less
than +0.05 and greater than -0.05.
eWood, wood-derived fuels, and biomass waste. Prior to 2001, includes non-biomass waste. Notes: Totals may not equal sum of components due to independent rounding. · The electric power sector
comprises electricity-only and combined-heat-and-power (CHP) plants within the NAICS 22 category whose primary
business is to sell electricity, or electricity and heat, to the public. · Through 1988, data are for electric utilities only.
Beginning in 1989, data include independent power producers. · 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.
fThere is a discontinuity in this time series between 1988 and 1989 due to the expanded coverage of renewable
energy sources beginning in 1989.

gSolar thermal and photovoltaic energy. Sources: Data sources, estimation procedures, and assumptions are described in the Technical Notes.
