1See "Primary Energy Consumption" in Glossary. 6Total 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. 2All values are estimated.  See Table 10.2b for notes on series components. 7Beginning in 1978, the small amounts of coal consumed for transportation are reported as industrial sector consumption. 3Natural gas only; excludes the estimated portion of supplemental gaseous fuels.  Data are for natural gas consumed in the operation of pipelines (primarily in compressors) and small amounts consumed as vehicle fuel.  See Table 6.5. 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."  Note:  Totals may not equal sum of components due to independent rounding. 5Electricity retail sales to ultimate customers reported by electric utilities and, beginning in 1996, other energy service providers.
