aSupplemental gaseous fuels (SGF) and fuel ethanol are consumed with natural gas and motor gasoline, respectively. In this table, natural gas excluding SGF and motor gasoline excluding fuel ethanol are presented so
that a fossil fuel total can be calculated. Natural gas including SGF and motor gasoline including fuel ethanol are presented separately for reference.
iSolar thermal and photovoltaic energy.
bThrough 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." jIncludes 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.
cLiquefied petroleum gases. kElectricity 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, and the 16 other petroleum products as described in the Technical Notes, Section 4, "Other Petroleum Products." 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.
fWood, wood-derived fuels, and biomass waste. Prior to 2001, includes non-biomass waste. Note: Totals may not equal sum of components due to independent rounding.
gExcludes denaturant. Pre-2005 estimates are not comparable to those for later years. See Section 5 of Technical Notes. Web Page: All data are available at http://www.eia.gov/state/seds/seds-data-complete.cfm.
hLosses and co-products from the production of fuel ethanol. Sources: Data sources, estimation procedures, and assumptions are described in the Technical Notes.
