FIGURE 2-18. Production of electricity in the United States in 2002 by fuel source. (From Freme, F., U.S. Coal Supply and Demand: 2002 Review, U.S. Department of Energy, Washington, D.C., 2002.)

1979 due to gains by natural gas and hydroelectric plants. While a balanced energy portfolio makes sense from an energy security issue, the increasing use of natural gas for baseloaded electricity generation is questionable and is discussed in detail in Chapter 8. Coal consumption in the nonelectric power sectors is low, relative to the electric power sector. Although consumption has fluctuated slightly, total coal usage for coke production and the industrial/commercial/residential sectors has remained relatively unchanged over the last 10 years.
