1Commercial sector, including commercial combined-heat-and-power (CHP) and commercial
electricity-only plants.
6A balancing item.  The sum of primary consumption in the five energy-use sectors equals the sum of
total consumption in the four end-use sectors.  However, total energy consumption does not equal the sum
of the sectoral components due to the use of sector-specific conversion factors for natural gas and coal.
2Industrial sector, including industrial combined-heat-and-power (CHP) and industrial electricity-only
plants.
R=Revised.  P=Preliminary.  (s)=Less than 0.5 trillion Btu.  
3Electricity-only and combined-heat-and-power (CHP) plants within the NAICS (North American
Industry Classification System) 22 category whose primary business is to sell electricity, or electricity and
heat, to the public.  Through 1988, data are for electric utilities only; beginning in 1989, data are for electric
utilities and independent power producers.
Notes:  ·  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.
4See "Primary Energy Consumption" in Glossary. Sources:  Tables 2.1b-2.1f.
5Total consumption consists of primary energy consumption, electricity retail sales, and electrical
system energy losses.  See Note, "Electrical System Energy Losses," at end of section.
