Coal plant by the water, for article on renewable energy capacity

The second-largest U.S. electric company by market value plans to exit all coal by 2035

Duke Energy will shut down all 11 of its remaining coal-fired power plants by 2035, spanning the Carolinas, Indiana, and Florida. The second-largest U.S. electric utility also plans to more than double its solar and wind capacity to 24,000 megawatts by 2030, backed by a $130 billion clean energy investment over the next decade. Duke serves roughly 8 million customers across six states, so its choices ripple outward into grid infrastructure, household bills, and the air people breathe near aging plants. When a utility this large commits to exiting coal entirely, it signals that clean energy economics have tipped — and offers a template other slow-moving utilities around the world may soon follow.
