1Anthracite, bituminous coal, subbituminous coal, lignite, waste coal, and coal synfuel. 9Batteries, chemicals, hydrogen, pitch, purchased steam, sulfur, and miscellaneous technologies.
2Distillate fuel oil, residual fuel oil, petroleum coke, jet fuel, kerosene, other petroleum, and waste oil. 10Included in "Wood."
3Natural gas, plus a small amount of supplemental gaseous fuels. 11Included in "Wind."
4Blast furnace gas, propane gas, and other manufactured and waste gases derived from fossil fuels. 12Through 1988, data are for electric utilities only.  Beginning in 1989, data are for electric utilities and
independent power producers.
5Through 1988, hydroelectric pumped storage is included in "Conventional Hydroelectric Power." R=Revised.  P=Preliminary.  NA=Not available.  - =No data reported.  (s)=Less than 0.05 million
kilowatts.  
6Wood and wood-derived fuels. Notes:  -  Data are at end of year.  -  For plants that use multiple sources of energy, capacity is assigned
to the energy source reported as the predominant one. - The electric power sector comprises
electricity-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.  -  See Table 8.11d for commercial and
industrial CHP and electricity-only data.  -  See Note 1, "Coverage of Electricity Statistics," and Note 2,
"Classification of Power Plants Into Energy-Use Sectors," at end of section.  -  See "Generator Net Summer
Capacity" in Glossary.  -  Totals may not equal sum of components due to independent rounding.
7Municipal solid waste from biogenic sources, landfill gas, sludge waste, agricultural byproducts, and
other biomass.  For all years, also includes non-renewable waste (municipal solid waste from non-biogenic
sources, and tire-derived fuels).
