As electricity demand in the United States rises—largely driven by the rapid expansion of AI-powered data centers—some policymakers and industry figures have proposed using existing backup diesel generators as a temporary energy solution. These generators, commonly installed at hospitals, office complexes, and data centers, collectively represent around 35 gigawatts of potential capacity. While this approach could help meet growing energy needs without major infrastructure investments, researchers warn it could have serious public health consequences.

According to an analysis by researchers including a Carnegie Mellon University team, diesel generators are among the most polluting energy sources, emitting fine particulate matter (PM2.5) that is linked to severe health problems and premature death. Using multiple air quality models, the researchers estimated that running these generators continuously to supply electricity for data centers could lead to approximately 500 additional prem
