Replacing Coal Plants With Renewables Is Cheaper 80% of the Time
A new report shows that the economics may not even support running U.S. coal plants, let alone building them.

About 80% of U.S. coal plants are now more expensive to keep running than to swap out for new wind and solar capacity, according to a report from Energy Innovation, a non-partisan climate and energy think tank.
While renewables cost more than fossil energy for much of the last century, prices for new wind and solar have dropped so quickly in recent years that they were already cheaper than new coal. This report shows that the price differential holds true for a growing amount of existing coal, as well. “This is becoming true for more and more plants moving forward—and at an accelerating pace,” said Eric Gimon, a senior fellow with Energy Innovation and a co-author of the report.
