The article discusses the investments made by Amazon and Google in nuclear power to fuel their data centers. Amazon has invested in a nuclear fusion startup called General Fusion, while Google has invested in a nuclear fission startup called Oklo. The investments highlight the tech giants’ efforts to secure reliable and carbon-free energy sources to power their energy-hungry data centers. Nuclear power, both fusion and fission, is seen as a potential solution to meet the growing energy demands of data centers while reducing carbon emissions. However, the article notes that nuclear fusion remains years away from practical applications, while advanced nuclear fission reactors face regulatory hurdles. The investments underscore the tech industry’s push for sustainable energy solutions to support their data-intensive operations.
