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 "Primary Energy Consumption" in Glossary. 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.
