Google Bets on Nuclear to Power the Future of AI
What happens when the world's most powerful tech company meets one of the most controversial energy sources? You get a bold new plan to fuel the future of artificial intelligence. On May 7, 2025, Google announced a partnership with Elementl Power to develop nuclear energy sites specifically designed to power its AI data centers. This isn't just a pivot-it's a seismic shift in how Big Tech plans to meet the growing energy demands of AI.
The Energy Problem No One Can Ignore
AI is hungry. Training large language models, running real-time inference, and storing massive datasets all require enormous amounts of electricity. According to the International Energy Agency, global data center energy use could double by 2030, with AI workloads driving much of that growth. Traditional energy sources-especially fossil fuels-are unsustainable. Renewables like solar and wind are clean but intermittent. That's where nuclear comes in.
Google's move is part of a broader trend. Microsoft has already signed a deal to buy nuclear power for its data centers. Amazon is investing in fusion startups. But Google's partnership with Elementl Power is unique in its focus on small modular reactors (SMRs), a next-generation nuclear technology that promises safer, more flexible, and more scalable energy production.
What Are Small Modular Reactors?
Unlike traditional nuclear plants, which are massive and expensive to build, SMRs are compact and can be manufactured off-site. Each unit can generate up to 300 megawatts of electricity-enough to power a large AI data center or a quarter of a million homes. They're designed with advanced safety features and can be deployed in remote or constrained locations, making them ideal for tech infrastructure.
Elementl Power, a rising player in the nuclear space, will work with Google to identify and develop SMR sites. Initial evaluations are set to begin in 2026, with the goal of bringing reactors online in the early 2030s. While that timeline may seem distant, the planning and regulatory hurdles for nuclear projects are notoriously complex. Starting now is the only way to be ready later.
Why Nuclear, and Why Now?
Google has committed to operating on 24/7 carbon-free energy by 2030. That's not just a PR goal-it's a logistical nightmare. Solar and wind are essential, but they can't provide consistent power around the clock. Batteries help, but they're expensive and limited. Nuclear offers a stable, high-density energy source that emits virtually no greenhouse gases during operation.
"This partnership is a game-changer for sustainable AI growth," a Google spokesperson said. "Nuclear energy provides the reliable, high-density power we need to innovate responsibly."
Supporters argue that nuclear is the only realistic way to meet the energy needs of AI while staying on track for climate goals. The International Energy Agency estimates that global nuclear capacity must increase by 80% by 2050 to keep warming below 1.5C. In that context, Google's move looks less like a gamble and more like a necessity.
The Critics Aren't Quiet
Not everyone is on board. Environmental groups have raised concerns about nuclear waste, safety risks, and the long timelines involved. The Sierra Club issued a statement calling the investment "a distraction from proven, faster-to-deploy renewables." They point out that solar panel costs have dropped by 80% since 2010, and wind is now one of the cheapest sources of electricity in many regions.
There's also skepticism about SMRs themselves. While the technology is promising, no commercial SMR has yet been deployed at scale. Critics worry that delays, cost overruns, or regulatory setbacks could derail the project. And with AI's energy needs growing fast, time is a luxury the industry may not have.
Balancing Innovation and Responsibility
Google's decision reflects a deeper tension in the tech world: how to balance rapid innovation with environmental responsibility. AI is transforming everything from healthcare to education, but it comes with a carbon cost. If the industry doesn't find sustainable ways to power its growth, the benefits of AI could be overshadowed by its environmental impact.
By investing in nuclear, Google is betting that long-term solutions are worth the wait. It's a high-stakes move that could set a precedent for how tech companies approach energy in the age of AI. If successful, it could redefine the infrastructure behind the digital world.
And if it fails? It will be a cautionary tale about the risks of chasing unproven technology in the race to power the future.
Either way, the message is clear: the energy behind AI matters just as much as the algorithms themselves.
