1Commercial sector, including commercial combined-heat-and-power (CHP) and commercial
electricity-only plants.		 7A 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.		 8Primary energy consumption total.  See Table 1.3.
3Electricity-only and combined-heat-and-power (CHP) plants within the NAICS 22 category whose
primary business is to sell electricity, or electricity and heat, to the public.		 R=Revised.  P=Preliminary.  (s)=Less than 0.5 trillion Btu.  
4Through 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.
5See Note 2, "Primary Energy Consumption," at end of Section 1. Sources:  Tables 1.3 and 2.1b-2.1f.
6Total energy consumption in the end-use sectors consists of primary energy consumption, electricity
retail sales, and electrical system energy losses.  See Note, "Electrical System Energy Losses," at end of
section.
