Coal was the main fuel used to generate electricity in the United States for many years. But the US Energy Information Administration says (1)in 2015 coal and natural gas were used equally to create electricity—about 33 percent each. The shift from coal to natural gas is happening at energy centers throughout the country. In July, coal was removed from the Clinch River Coal Plant in Russell County, Virginia. The plant is owned by American Electric Power. Last year, parts of the center were converted from coal to natural gas use. Ricky Chaffin is the manager of the plant. He says it is now not only cleaner but produces more electricity. “You don’t have to handle the coal,” he says. “You don’t have to move the coal from the pile to the plant. We’ve got a lot less equipment. So there is a whole lot less manpower required to operate a natural gas plant,” he said. When the plant was fueled by coal, 182 people were needed to operate it. Now, 46 people work there. (2)The US Energy Information Administration has predicted that natural gas will become the country’s largest source of electricity this year.
