aNatural gas as it is consumed; includes supplemental gaseous fuels that are commingled with natural gas. iFrom 1981 through 1992, includes fuel ethanol blended into motor gasoline that is not included in the motor gasoline
column.
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."		 jElectricity imports are included in total primary energy and electric power sector but are not shown separately.
cLiquefied petroleum gases. Where shown, R = Revised data and (s) = Value less than 0.05 million dollars.
dBeginning in 1993, includes fuel ethanol blended into motor gasoline. Where shown, — = No consumption, including cases where adjustments were made. See explanation of adjustments in
Section 7 of the Technical Notes.
eIncludes asphalt and road oil, aviation gasoline, kerosene, lubricants, and the other petroleum products as described in
the Technical Notes, Section 4, "Other Petroleum Products."		 Note: Expenditure totals may not equal sum of components due to independent rounding.
fWood, wood-derived fuels, and biomass waste. Prior to 2001, includes non-biomass waste. Web Page: All data are available at http://www.eia.gov/state/seds/seds-data-complete.cfm.
gThere is a discontinuity in this time series between 1988 and 1989 due to the expanded coverage of the use of wood and
biomass waste beginning in 1989.		 Sources: Data sources, estimation procedures, and assumptions are described in the Technical Notes.
hThere are no direct fuel costs for hydroelectric, geothermal, wind, photovoltaic, or solar thermal energy.
