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.

aIncludes supplemental gaseous fuels that are commingled with natural gas. hIncludes denaturant. Because of differences in data sources and estimation methods, the ratio of fuel ethanol
consumption and motor gasoline consumption should not be interpreted as the average ethanol blend rate.
bBeginning in 2009, includes biodiesel blended into distillate fuel oil. Beginning in 2011, includes renewable diesel
blended into distillate fuel oil. Excludes biofuels product supplied.
NA = Not available.
cHydrocarbon gas liquids, include natural gas liquids and refinery olefins. Where shown, R = Revised data and (s) = Value less than 0.5.
dThrough 2004, includes kerosene-type and naphtha-type jet fuel. Beginning in 2005, includes kerosene-type jet fuel only;
naphtha-type jet fuel is included in "Other Petroleum."
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.
eBeginning in 1993, includes fuel ethanol blended into motor gasoline. Web Page: All data are available at https://www.eia.gov/state/seds/seds-data-complete.php.
fIncludes asphalt and road oil, aviation gasoline, kerosene, lubricants, petroleum coke, and the “other petroleum products”
category. See Technical Notes, Section 4.
