The Biden administration on Thursday placed the final cornerstone of its plan to tackle climate change: a regulation that would force the nation's coal-fired power plants to virtually eliminate the planet-warming pollution that they release into the air or shut down.
The regulation from the Environmental Protection Agency requires coal plants in the United States to reduce 90 percent of their greenhouse pollution by 2039, one year earlier than the agency had initially proposed. The compressed timeline was welcomed by climate activists but condemned by coal executives who said the new standards would be impossible to meet.
The E.P.A. also imposed three additional regulations on coal-burning power plants, including stricter limits on emissions of mercury, a neurotoxin linked to developmental damage in children, from plants that burn lignite coal, the lowest grade of coal. The rules also more tightly restrict the seepage of toxic ash from coal plants into water supplies and limit the discharge of wastewater from coal plants.
Taken together, the regulations could deliver a death blow in the United States to coal, the fuel that powered the country for much of the last century but has caused global environmental damage. When burned, coal emits more carbon dioxide than any other fuel source.
One thing to note, coal has been dying, just slowly. A capitalism success story really.
The coal industry in the United States has been on a precipitous decline for over a decade, as environmental regulations and a boom in natural gas, wind and solar power made it more expensive to burn coal, and power generation shifted toward those cheaper, cleaner sources of electricity. In 2023, coal-fired power plants generated 16.2 percent of the nation's electricity, according to the U.S. Energy Information Agency, down from a peak of 52 percent in 1990. There are about 200 coal-burning power plants still operating, with many concentrated in Pennsylvania, Texas and Indiana.
