1See "Primary Energy Consumption" in Glossary. 6Electricity retail sales to ultimate customers reported by electric utilities and, beginning in 1996, other energy service providers. 2Most values are estimated.  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. R=Revised.  P=Preliminary.  NA=Not available.  (s)=Less than 0.5 trillion Btu.   4Does not include the ethanol portion of motor gasoline—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. 5Conventional hydroelectric power.
