1See Note 2, "Primary Energy Consumption," at end of Section 1. 6Electricity retail sales to ultimate customers reported by electric utilities and, beginning in 1996, other
energy service providers.
2Most data are estimates.  See Table 10.2a for notes on series components and estimation. 7Total losses are calculated as the primary energy consumed by the electric power sector minus the
energy content of electricity retail sales.  Total losses are allocated to the end-use sectors in proportion to
each sector's share of total electricity retail sales.  See Note, "Electrical System Energy Losses," at end of
section.
3Natural gas only; excludes the estimated portion of supplemental gaseous fuels.  See Note 1,
"Supplemental Gaseous Fuels," at end of Section 6.		 R=Revised.  P=Preliminary.  NA=Not available.  (s)=Less than 0.5 trillion Btu.  
4Does not include the fuel ethanol portion of motor gasoline—fuel ethanol is included in "Biomass." Notes:  ·  The commercial sector includes commercial combined-heat-and-power (CHP) and commercial
electricity-only plants.  See Note 2, "Classification of Power Plants Into Energy-Use Sectors," at end of
Section 8.  ·  Totals may not equal sum of components due to independent rounding.
