It would be cheaper to build local wind and solar projects than continuing to operate 74 percent of U.S. coal plants, according to a new report from Energy Innovation, a clean energy advocacy and research organization, and Vibrant Clean Energy. The levelized cost of energy from new renewables plants built within 35 miles of an existing coal-fired station is lower than that of 74 percent, or 211 gigawatts, of the 2017 U.S. coal fleet, the authors claim. By 2025, the report bumps at-risk coal capacity up to 246 gigawatts, the current size of the U.S. fleet. “This is not a fantasy of a supercomputer. This is really what’s happening today,” said Eric Gimon, a senior fellow at Energy Innovation.
