News release includes statistics and charts: “The mix of fuels used to generate the electricity in homes, factories, and businesses across the United States has changed in the past few years as coal, still the largest single fuel used for electricity, has lost some of its share of the generation market to natural gas and non-hydroelectric renewables. The generation mix is not uniform across the country and varies significantly by region depending on available resources and regional market prices. A periodic series of Today in Energy articles in the coming weeks will focus on the changes in fuel use for electricity generation in recent years for seven regions of the United States. Natural gas has gained market share from coal in much of the country, but this is less true in markets closer to the cheaper Powder River Basin coal in the West. Renewable sources are generally growing, especially in Texas and the West. Petroleum-fired electricity generation has been declining for several decades, but it can play an important role at rare times when other alternatives are not available.”
