Amazon has joined Microsoft and Google in supporting nuclear energy by investing in startup X-Energy. The tech giant announced three deals to develop small modular reactors (SMRs) that will add 300 megawatts of capacity in data center regions of the Pacific Northwest and Virginia. The construction of four SMRs in Washington could ultimately power one million homes. X-Energy's innovative reactor design promises a safer fuel system and aims to generate 5,000 megawatts of new nuclear power by 2039. These initiatives mark a significant shift towards nuclear energy amidst rising competition from renewable sources.
