The electric power sector consists of facilities which generate electricity primarily for use by the public. Energy is used for the generation, distribution, and transmission of electric power.
Total electric power sector expenditures on energy decreased 1.6 percent to $475.2 million from 2013 to 2014. Nuclear fuel expenditures increased 35 percent, wood and waste expenditures increased 21 percent, natural gas expenditures increased 7.5 percent, and petroleum expenditures increased 3.3 percent. Coal expenditures decreased 8.1 percent.
In 2014, the electric power sector spent $355.5 million for coal, $81.0 million for nuclear fuel, $24.5 million for natural gas, $12.5 million for petroleum, and $1.7 million for wood and waste. There were no direct fuel costs for hydroelectric, geothermal, wind, photovoltaic, or solar thermal energy.
Coal expenditures were nearly three–quarters (74.8 percent) of the money spent in the electric power sector on energy in 2014. Expenditures on nuclear fuel and natural gas were 17.1 percent and 5.2 percent, respectively, of the total. Petroleum expenditures were 2.6 percent while wood and waste expenditures were 0.36 percent of the total.
The expenditures are in nominal dollars to provide a better comparison.
