aIncludes 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 the 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 consists
of 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
