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).
