The Growing Energy Appetite of Artificial Intelligence
Artificial intelligence (AI) is dramatically reshaping the global energy landscape. As millions of users interact with generative AI tools, the resulting energy consumption is placing unprecedented strain on existing power grids. A single Google search consumes as much electricity as turning on a household light for 17 seconds. However, asking a generative AI model like ChatGPT a single question uses the equivalent energy of leaving that same bulb on for 20 minutes. Image generation by AI can require 6,250 times more energy — about the same as fully charging a smartphone or keeping a light on for 87 straight days.
This surge in demand has led major technology companies to seek reliable and sustainable energy sources. The solution, it seems, may lie in a long-dismissed yet powerful option: nuclear energy.
Why the Grid Isn’t Ready for AI
AI systems rely on data centers that operate 24/7, consuming massive amounts of electricity. Renewable sources like wind and solar, while sustainable, are intermittent and can’t consistently meet these demands. Fossil fuels offer reliable power but come with environmental drawbacks and volatile prices, making them less attractive to companies with carbon-neutral goals.
Tech giants like Google, Amazon, Microsoft, and Meta are reaffirming their commitment to reducing CO2 emissions. These goals align poorly with fossil fuels, prompting a renewed interest in nuclear energy — a reliable, low-carbon energy source that operates continuously and efficiently.
Nuclear Energy’s Return to the Spotlight
In recent years, tech companies have made significant moves toward nuclear partnerships. Meta issued a call for nuclear proposals, while Google committed to buying reactors from Kairos Power. Amazon has partnered with Energy Northwest and Dominion Energy to pursue nuclear development, and Microsoft signed a 20-year deal to restart the Three Mile Island Unit 1 reactor.
Nuclear energy’s advantages include constant output, low carbon emissions, and predictable fuel costs, making it an ideal match for energy-hungry AI operations. Still, overcoming the technology’s historical challenges — high costs and long construction times — remains critical.
Economic Feasibility in the Age of AI
Historically, nuclear energy projects were seen as too expensive and slow. Building a 1.1-gigawatt nuclear plant can cost around $7.77 billion, with some projects like Georgia’s Vogtle Units 3 and 4 exceeding $36 billion. However, compared to the cost of AI infrastructure, these figures are becoming more palatable. For instance, the first phase of OpenAI and SoftBank’s Stargate AI project is projected to cost $100 billion — enough to justify powering it with a single nuclear plant.
Construction timelines are another hurdle, with nuclear plants taking 6 to 7.5 years to complete. Tech companies are addressing this by guaranteeing long-term electricity purchases, giving power providers the confidence to invest in long-term projects. Some companies are even acquiring nuclear firms or situating data centers adjacent to nuclear power plants for logistical efficiency.
Changing Perceptions Around Nuclear Energy
Public perception has long been a barrier to nuclear energy’s expansion. Despite being one of the cleanest and safest energy sources, nuclear power has been stigmatized due to concerns about accidents and waste. In reality, nuclear energy produces only 6 tonnes of CO2 per gigawatt-hour — far less than coal (970 tonnes), natural gas (720 tonnes), and even solar (53 tonnes).
It’s also among the safest forms of energy. Statistics show it causes 820 times fewer deaths than coal and is comparable in safety to wind and solar. While disasters like Fukushima have left lasting impressions, no deaths from radiation exposure occurred, according to an 80-expert United Nations panel. Nuclear waste management, another common concern, has also seen safe and effective solutions in place for decades.
Big Tech’s Billion-Dollar Bet
AI’s insatiable energy needs have brought nuclear energy back into strategic focus. Big Tech is now investing billions into nuclear solutions, believing they can solve not only their own energy challenges but also help reshape global energy infrastructure. These efforts could transform nuclear from a misunderstood relic into a cornerstone of a clean energy future.
By classifying nuclear energy as green and encouraging financial institutions like the World Bank to lift bans on nuclear project funding, technology companies are changing the narrative. Their involvement may finally overcome decades of hesitancy surrounding nuclear power.
In essence, AI’s rise could inadvertently lead to a nuclear renaissance. As tech companies seek stable, sustainable power, nuclear energy is emerging as a vital ally in powering the future — and in doing so, it may also change public perceptions and global policy around clean energy.
