Section 10. Renewable energy
Sources. The Nation consumed 5.9 quadrillion Btu of renewable energy in 2002, accounting for 6 percent (1) of total energy consumption during the year. At 2.7 quadrillion Btu, conventional hydroelectric power was the largest component of the renewable energy total, measuring 45 percent of the total. Wood was the next largest component at 2.0 quadrillion Btu and 34 percent of the total. Waste, the third largest component of the renewable energy total, contributed 0.6 quadrillion Btu in 2002, a 9-percent share of the total.
Electric Power Sector. In 2002, the electric power sector consumed 3.5 quadrillion Btu of renewable energy resources, 1.1 quadrillion Btu more than all of the end-use sectors combined and a share of 59 percent of the total. Conventional hydroelectric power recorded 2.6 quadrillion Btu in 2002, for 75 percent of the electric power sector total. Waste, at 0.3 quadrillion Btu, was the second largest source consumed for electricity generation, followed by geothermal and wood.
End-Use Sectors. Of the end-use sectors, the industrial sector was the largest consumer of renewable energy in 2002. Industrial facilities used 1.7 quadrillion Btu of renewable energy in 2002, 87 percent in the form of wood. The residential sector was the next largest end-use sector in the use of renewable energy, consuming 0.4 quadrillion Btu–84 percent in the form of wood, 14 percent solar, and 2 geothermal. The transportation sector consumed renewable energy in the form of alcohol fuels used in the blending of motor gasoline; in 2002, alcohol fuel use was 0.2 quadrillion Btu. The commercial sector used 0.1 quadrillion Btu in 2002, 48 percent of it as waste and 42 percent as wood.

(a) 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.
(b) Through 1988, data are for consumption at electric utilities only.
Beginning in 1989, data also include consumption at independent power
producers.
(c) Conventional hydroelectric power.
(d) Wood, black liquor, and other wood waste.
(e) Municipal solid waste, landfill gas, sludge waste, tires,
agricultural byproducts, and other biomass.
(f) Geothermal electricity net generation.
(g) Solar thermal and photovoltaic electricity net generation.
(h) Wind electricity net generation.
