1Beginning in 2001, includes a small amount of refuse recovery (coal recaptured from a refuse mine,
and cleaned to reduce the concentration of noncombustible materials).		 R=Revised.  P=Preliminary.  NA=Not available.  
2Waste coal (including fine coal, coal obtained from a refuse bank or slurry dam, anthracite culm,
bituminous gob, and lignite waste) consumed by the electric power and industrial sectors.  Beginning in
1989, waste coal supplied is counted as a supply-side item to balance the same amount of waste coal
included in "Consumption."		 Note:  The values in this table are for gross heat contents.  See "Heat Content" in Glossary. 
3Includes transportation.  Excludes coal synfuel plants. Web Page:  See http://www.eia.gov/totalenergy/data/monthly/#appendices for updated annual
conversion factors.
4Electricity-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.  Through 1988, data are for
electric utilities only; beginning in 1989, data are for electric utilities and independent power producers.		 Sources:  See "Thermal Conversion Factor Source Documentation," which follows Table A6.
5Electric power sector factors are for anthracite, bituminous coal, subbituminous coal, lignite, waste
coal, and, beginning in 1998, coal synfuel.
