Major technology firms are increasingly turning to nuclear energy to sustain the massive power requirements of artificial intelligence data centers. Following Microsoft’s recent agreement to revive a reactor at Three Mile Island, Google and Amazon have also announced significant investments in Small Modular Reactors (SMRs). Industry leaders argue that nuclear power provides a reliable, carbon-free 'baseload' energy source that intermittent renewables like wind and solar cannot currently match at scale. However, the shift has sparked debate among environmental advocates and energy experts. While supporters view nuclear as essential for meeting net-zero goals, critics point to the long-standing challenges of radioactive waste disposal, high capital costs, and the lengthy timelines for regulatory approval. Financial analysts suggest this trend marks a pivotal moment in the energy sector, as the tech industry’s demand for 24/7 electricity forces a re-evaluation of global power infrastructure.
