aFor expenditures, natural gas only; excludes supplemental gaseous fuels (SGF). Through 1979, includes unknown quantities of SGF. eElectric plants used municipal waste at no charge. bWood and waste.  Prior to 2001, includes non-biomass waste. Where shown, R = Revised data, — = No consumption, and (s) = Value less than 0.05 million nominal dollars. cElectricity imported from Canada and Mexico. Note:  Expenditure totals may not equal sum of components due to independent rounding. dThere are no direct fuel costs for hydroelectric, geothermal, wind, photovoltaic, or solar thermal energy.
