The infamous Three Mile Island nuclear power plant, the site of the 1979 partial meltdown, is set to reopen under a new agreement between Microsoft and Constellation Energy. This initiative aims to provide carbon-free energy to meet the growing demands of Microsoft's AI data centers. The 20-year deal will restore operations at the long-dormant reactor, expected to provide substantial energy with a capacity of up to 835 megawatts, while also bringing approximately 3,400 jobs back to Pennsylvania. Amid an increasing reliance on nuclear power for sustainability, the revival of Three Mile Island signifies a significant shift towards incorporating clean energy sources into technological advancements, particularly in the AI sector. The news has already spurred activity in uranium ETFs, reflecting the market's optimism about nuclear energy's role in powering the future.
