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,
independent power producers, commercial plants, and industrial plants.

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. ·  See Note 1, "Coverage of Electricity Statistics," 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).		 Web Page:  For related information, see http://www.eia.gov/electricity/.
