Trump is making coal plants even dirtier as AI demands more energy
February 20, 2026
The Trump administration has rolled back critical pollution regulations, specifically the Mercury and Air Toxics Standards (MATS), which were designed to limit toxic emissions from coal-fired power plants. This deregulation coincides with a rising demand for electricity driven by the expansion of AI data centers, leading to the revival of older, more polluting coal plants. The rollback is expected to save the coal industry approximately $78 million annually but poses significant health risks, particularly to children, due to increased mercury emissions linked to serious health issues such as birth defects and learning disabilities. Environmental advocates argue that these changes prioritize economic benefits for the coal industry over public health and environmental safety, as the U.S. shifts towards more energy-intensive technologies like AI and electric vehicles. The Tennessee Valley Authority has also decided to keep two coal plants operational to meet the growing energy demands, further extending the lifespan of aging, polluting infrastructure.
