aSupplemental gaseous fuels (SGF) and biofuels are consumed with natural gas and petroleum products. In this table, SGF and biofuels are removed from natural gas and petroleum so that a fossil fuel total can be calculated without
double-counting. Biofuels are included in "Renewable Energy."
jSolar thermal and photovoltaic energy.
bHydrocarbon gas liquids, include natural gas liquids and refinery olefins. kIncludes the energy losses associated with the generation, transmission, and distribution of the electricity flowing across state lines. A positive number indicates that more electricity came into the state than went out of the state during the
year. Pre-1990 estimates are not comparable to those for later years. See Section 6 of Technical Notes for an explanation of changes in methodology.
cThrough 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." lElectricity traded with Canada and Mexico. Calculated by converting net imports in kilowatthours by 3,412 Btu per kilowatthour.
dIncludes asphalt and road oil, aviation gasoline, kerosene, lubricants, petroleum coke, and the “other petroleum products” category. See Technical Notes, Section 4. NA = Not available.
eConventional hydroelectric power. For 1960 through 1989, includes pumped-storage hydroelectricity, which cannot be separately identified. Where shown, R = Revised data and (s) = Value less than +0.05 and greater than -0.05 trillion Btu.
fThere 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.
gWood, wood-derived fuels, and biomass waste. Prior to 2001, includes non-biomass waste. Web Page: All data are available at https://www.eia.gov/state/seds/seds-data-complete.php.
hExcludes 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. Pre-2005 estimates
are not comparable to those for later years. See Section 5 of Technical Notes.
Sources: Data sources, estimation procedures, and assumptions are described in the Technical Notes.
iLosses and co-products from the production of biodiesel and fuel ethanol.
