WASHINGTON (AP) - A federal report said Americans are using less coal this year than at any time since Jimmy Carter's presidency.
The U.S. Energy Information Administration projected Tuesday that the country will end 2018 having used less coal than at any time since 1979.
The report cites ongoing competition from cheap and cleaner-burning forms of energy, especially natural gas. Tighter pollution rules also have shut some older, dirtier coal plants.
The electrical grid is the main user of coal. With U.S. demand falling since 2007, federal officials said, this year will be the second-biggest on record for mothballing of U.S. coal plants.
