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 increased 1.5 percent to $483.0 million from 2012 to 2013. Petroleum expenditures nearly doubled, nuclear fuel expenditures increased 28 percent, and wood and waste expenditures increased 8 percent. Natural gas expenditures decreased 25 percent, and coal expenditures decreased 1 percent.
In 2013, the electric power sector spent $386.7 million for coal, $60.0 million for nuclear fuel, $22.8 million for natural gas, $12.1 million for petroleum, and $1.4 million for wood and waste. There were no direct fuel costs for hydroelectric, geothermal, wind, photovoltaic, or solar thermal energy.
Coal expenditures were over three–quarters (80.1 percent) of the money spent in the electric power sector on energy in 2013. Expenditures on nuclear fuel and natural gas were 12.4 percent and 4.7 percent, respectively, of the total. Petroleum expenditures were 2.5 percent while wood and waste expenditures were 0.3 percent of the total.
The expenditures are in nominal dollars to provide a better comparison.
