Amazon's investment in small modular nuclear reactors (SMRs) marks a strategic shift towards sustainable energy to meet growing electricity demands driven by AI and data centers. By leading a $500 million funding round for X-Energy Reactor, Amazon aims to generate over 5 gigawatts of power by 2039, aligning with its goal of 100% renewable energy consumption by 2030. This initiative highlights the tech industry's collective effort to adopt innovative, carbon-free energy solutions, despite regulatory, financial, and public perception challenges.
