State Profile and Energy Estimates

Changes to the State Energy Data System (SEDS) Notice: In October 2023, we updated the way we calculate primary energy consumption of electricity generation from noncombustible renewable energy sources (solar, wind, hydroelectric, and geothermal). Visit our Changes to 1960—2022 conversion factor for renewable energy page to learn more.

bIncludes supplemental gaseous fuels that are commingled with natural gas. 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.
cHydrocarbon gas liquids, assumed to be propane only. – – = Not applicable. NA = Not available.
dWood and wood-derived fuels. Where shown, R = Revised data and (s) = Physical unit value less than 0.5 or Btu value less than 0.05.
eThere 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 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.
fSolar thermal and photovoltaic energy. Includes solar thermal energy consumed as heat by the commercial and industrial
sectors.
