Technology giants are turning to nuclear energy to power the energy-intensive data centers needed to train and run the massive artificial intelligence models behind today’s generative AI applications.
Microsoft and Google are among the firms agreeing deals to purchase nuclear power from certain suppliers in the U.S. to bring additional energy capacity online for its data centers.
This week, Google said it would purchase power from Kairos Power, a developer of small modular reactors, to help “deliver on the progress of AI.”
“The grid needs these kinds of clean, reliable sources of energy that can support the build out of these technologies,” Michael Terrell, senior director for energy and climate at Google, said on a call with reporters Monday.
“We feel like nuclear can play an important role in helping to meet our demand, and helping meet our demand cleanly, in a way that’s more around the clock.”
Google said its first nuclear reactor from Kairos Power would be online by 2030, with more reactors going live through 2035.
The tech giant isn’t the only firm looking to nuclear power to realize its AI ambitions. Last month, Microsoft signed a deal with U.S. energy firm Constellation to resurrect a defunct reactor at the Three Mile Island nuclear power plant in Pennsylvania, whose reactor has been dormant for five years.
The Three Mile Island plant was the location of the most serious nuclear meltdown and radiation leak in U.S. history in March 1979, when the loss of water coolant through a faulty valve caused a reactor to overheat.
Why they’re turning to nuclear
Tech companies are under pressure to find energy sources to power data centers — a key piece of infrastructure behind modern-day cloud computing and AI applications.
Many developers rent out servers equipped with GPUs (graphics processing units), which would typically be too expensive to own outright, from so-called cloud “hyperscalers” — such as Amazon, Microsoft and Google.
These tech giants have benefited from a surge of interest in generative AI applications such as OpenAI’s ChatGPT. But that increase in demand has also led to an unintended effect: correspondingly large spikes in the amount of energy required.
Global electricity consumption from data centers, artificial intelligence and the cryptocurrency sector is expected to double from an estimated 460 terawatt-hours (TWh) in 2022 to more than 1,000 TWh in 2026, according to a research report from the International Energy Agency.
Researchers at the University of California, Riverside, published a study in April last year that found ChatGPT consumes 500 milliliters of water for every 10 to 50 prompts, depending on when and where the AI model is deployed. That equates to roughly the amount of water in a standard 16-ounce bottle.
As of August, there were more than 200 million people submitting questions on OpenAI’s popular chatbot ChatGPT every week, according to OpenAI. That’s double the 100 million weekly active users OpenAI reported last November.
Environmental opposition
Nuclear energy isn’t without its controversy. Many climate activists oppose such supplies, citing their hazardous environmental and safety risks, and the fact that they do not offer a genuine source of renewable power.
“Nuclear power is incredibly expensive, hazardous and slow to build,” the climate charity Greenpeace says on its website.
“It is often referred to as ‘clean’ energy because it doesn’t produce carbon dioxide or other greenhouse gases when electricity is generated but the reality is that it isn’t a plausible alternative to renewable energy sources.”
Proponents of nuclear energy, on the other hand, say that it offers a nearly carbon-free form of electricity and is more reliable than renewable sources like solar and wind.
“If it is built and securitized in the right way, I do think nuclear is the future,” Rosanne Kincaid-Smith, chief operating officer of Northern Data Group, a global data center provider, told CNBC at a tech conference in London last week.
“People are scared of nuclear because of the disasters we’ve had in the past. But what’s coming, I just don’t see traditional grids being the sustainable power that’s ongoing in the development of AI,” Kincaid-Smith added.
While Northern Data Group isn’t using nuclear energy — nor is it actively exploring plans to use nuclear as a power source for its AI data centers — the firm does want to “contribute to that conversation because it’s important for the wider ecosystem, the wider economy,” Kincaid-Smith told CNBC.

Thanks to Trump’s repeated executive order attacks on US clean energy policy, nearly $8 billion in investments and 16 new large-scale factories and other projects were cancelled, closed, or downsized in Q1 2025.
The $7.9 billion in investments withdrawn since January are more than three times the total investments cancelled over the previous 30 months, according to nonpartisan policy group E2’s latest Clean Economy Works monthly update.
However, companies continue to invest in the US renewable sector. Businesses in March announced 10 projects worth more than $1.6 billion for new solar, EV, and grid and transmission equipment factories across six states. That includes Tesla’s plan to invest $200 million in a battery factory near Houston that’s expected to create at least 1,500 new jobs. Combined, the projects are expected to create at least 5,000 new permanent jobs if completed.
Michael Timberlake of E2 said, “Clean energy companies still want to invest in America, but uncertainty over Trump administration policies and the future of critical clean energy tax credits are taking a clear toll. If this self-inflicted and unnecessary market uncertainty continues, we’ll almost certainly see more projects paused, more construction halted, and more job opportunities disappear.”

March’s 10 new projects bring the overall number of major clean energy projects tracked by E2 to 390 across 42 states and Puerto Rico. Companies have said they plan to invest more than $133 billion in these projects and hire 122,000 permanent workers.
Since Congress passed federal clean energy tax credits in August 2022, 34 clean energy projects have been cancelled, downsized, or shut down altogether, wiping out more than 15,000 jobs and scrapping $10 billion in planned investment, according to E2 and Atlas Public Policy.
However, in just the first three months of 2025, after Trump started rolling back clean energy policies, 13 projects were scrapped or scaled back, totaling more than $5 billion. That includes Bosch pulling the plug on its $200 million hydrogen fuel cell plant in South Carolina and Freyr Battery canceling its $2.5 billion battery factory in Georgia.
Republican-led districts have reaped the biggest rewards from Biden’s clean energy tax credits, but they’re also taking the biggest hits under Trump. So far, more than $6 billion in projects and over 10,000 jobs have been wiped out in GOP districts alone.
And the stakes are high. Through March, Republican districts have claimed 62% of all clean energy project announcements, 71% of the jobs, and a staggering 83% of the total investment.
A full map and list of announcements can be seen on E2’s website here. E2 says it will incorporate cancellation data in the coming weeks.

Tesla has reportedly delayed the launch of its new “affordable EV,” which is believed to be a stripped-down Model Y, in the United States.
Last year, Tesla CEO Elon Musk made a pivotal decision that altered the automaker’s direction for the next few years.
The CEO canceled Tesla’s plan to build a cheaper new “$25,000 vehicle” on its next-generation “unboxed” vehicle platform to focus solely on the Robotaxi, utilizing the latest technology, and instead, Tesla plans to build more affordable EVs, though more expensive than previously announced, on its existing Model Y platform.
Musk has believed that Tesla is on the verge of solving self-driving technology for the last few years, and because of that, he believes that a $25,000 EV wouldn’t make sense, as self-driving ride-hailing fleets would take over the lower end of the car market.

However, he has been consistently wrong about Tesla solving self-driving, which he first said would happen in 2019.
In the meantime, Tesla’s sales have been decreasing and the automaker had to throttle down production at all its manufacturing facilities.
That’s why, instead of building new, more affordable EVs on new production lines, Musk decided to greenlight new vehicles built on the same production lines as Model 3 and Model Y – increasing the utilization rate of its existing manufacturing lines.
Those vehicles have been described as “stripped-down Model Ys” with fewer features and cheaper materials, which Tesla said would launch in “the first half of 2025.”
Reuters is now reporting that Tesla is seeing a delay of “at least months” in launching the first new “lower-cost Model Y” in the US:
Tesla has promised affordable vehicles beginning in the first half of the year, offering a potential boost to flagging sales. Global production of the lower-cost Model Y, internally codenamed E41, is expected to begin in the United States, the sources said, but it would be at least months later than Tesla’s public plan, they added, offering a range of revised targets from the third quarter to early next year.
Along with the delay, the report also claims that Tesla aims to produce 250,000 units of the new model in the US by 2026. This would match Tesla’s currently reduced production capacity at Gigafactory Texas and Fremont factory.
The report follows other recent reports coming from China that also claimed Tesla’s new “affordable EVs” are “stripped-down Model Ys.”
The Chinese report references the new version of the Model 3 that Tesla launched in Mexico last year. It’s a regular Model 3, but Tesla removed some features, like the second-row screen, ambient lighting strip, and it uses fabric interior material rather than Tesla’s usual vegan leather.
The new Reuters report also said that Tesla planned to follow the stripped-down Model Y with a similar Model 3.
In China, the new vehicle was expected to come in the second half of 2025, and Tesla was waiting to see the impact of the updated Model Y, which launched earlier this year.
Electrek’s Take
These reports lend weight to what we have been saying for a year now: Tesla’s “more affordable EVs” will essentially be stripped-down versions of the Model Y and Model 3.
While they will enable Tesla to utilize its currently underutilized factories more efficiently, they will also cannibalize its existing Model 3 and Y lineup and significantly reduce its already dwindling gross margins.
I think Musk will sell the move as being good in the long term because it will allow Tesla to deploy more vehicles, which will later generate more revenue through the purchase of the “Full Self-Driving” (FSD) package.
However, that has been his argument for years, and it has yet to pan out as FSD still requires driver supervision and likely will for years to come, resulting in an extremely low take-rate for the $8,000 package.
