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.

Block jumped more than 5% on Monday, leading a rally in shares of fintech companies as analysts downplayed the threat of JPMorgan Chase’s reported plan to charge data aggregators for access to customer financial information.
The recovery followed steep declines on Friday, after Bloomberg reported that JPMorgan had circulated pricing sheets outlining potential fees for aggregators like Plaid and Yodlee, which connect fintech platforms to users’ bank data.
In a note to clients on Monday, Evercore ISI analysts said the potential new expenses were “far from a ‘business model-breaking’ cost increase.”
In addition to Block’s rise, PayPal climbed 3.5% on Monday after sliding Friday. Robinhood and Shift4 recorded modest gains.
Broader market momentum helped fuel some of the rebound. The Nasdaq closed at a record, and crypto rallied, with bitcoin climbing past $123,000. Ether, solana, and other altcoins also gained.
Evercore ISI’s analysts said that even if JPMorgan’s changes were implemented, the most immediate effect would be a slight bump in the cost of one-time account setups — perhaps 50 to 60 cents.
Morgan Stanley echoed that view, writing that any impact would be “negligible,” especially for large fintechs that rely more on debit, credit, or stored balances than bank account pulls for transactions.
PayPal doesn’t anticipate much short-term impact, according to a person with knowledge of the issue. The person, who asked not to be named in order to speak about private financial matters, noted that PayPal relies on aggregators primarily for account verification and already has long-term pricing contracts in place.
While smaller fintechs that depend heavily on automated clearing house (ACH) rails or Open Banking frameworks for onboarding and compliance may face real pressure if the fees take effect, analysts said the larger platforms are largely insulated.

The global EV market is still charging ahead. According to new numbers from global research firm Rho Motion, 9.1 million EVs were sold worldwide in the first half of 2025, up 28% compared to the same period last year. But not every region is accelerating at the same pace.
China and Europe are doing the heavy lifting
More than half of the world’s EVs this year have been bought in China. That market hit 5.5 million sales in the first six months of 2025 – a 32% jump year-over-year. Around half of new cars bought in China are now electric.
While some Chinese cities’ subsidies have dried up, Rho Motion expects momentum to pick back up later in the year as more funding is released.
In Europe, 2 million EVs were sold in the first half of the year, up 26%. Battery electric vehicle (BEV) sales also rose 26%, thanks in part to affordable models like the Renault 4 (pictured) and 5 entering the market. Plug-in hybrids (PHEVs) weren’t far behind, growing 27% year-to-date. Chinese automakers are leaning into PHEVs as a way to work around the EU’s new tariffs on BEVs.
Spain is leading the pack with EV sales soaring 85% so far this year. Its generous MOVES III incentive program was extended in April and has kept sales strong. The UK and Germany are also seeing solid growth – 32% and 40%, respectively. France, however, is slumping. With subsidies cut, EV sales there have dropped 13%.
North America is stuck in the slow lane
Things aren’t looking quite as bright in North America. EV sales in the US, Canada, and Mexico are up just 3% so far this year.
Mexico is the one bright spot, with a 20% boost. The US is up 6%. But Canada is down a whopping 23%.
And things could get bumpier. On July 4, Trump signed Congress’s big bill into law, which axes all the Inflation Reduction Act EV tax credits. Those consumer credits for EVs now officially end on September 30.
Just over half of the EVs sold in the US this year qualified for those credits. Rho Motion predicts a rush in Q3 before the subsidies disappear – and a decline in sales after that.
Rho Motion data manager Charles Lester said, “With Trump’s latest cuts in his ‘Big Beautiful Bill,’ the US could struggle to see any growth in the EV market overall in 2025.”

Lucid’s electric sedan can drive further, charge faster, and packs more advanced tech than most of the competition. That might explain why it’s leading the segment. The Lucid Air remained the best-selling luxury EV sedan in the US after widening its lead in the Q2.
The Lucid Air is America’s best-selling luxury EV sedan
The 2025 Lucid Air Pure arrived as the “World’s most efficient car” with an EPA-estimated range of 420 miles and a record 146 MPGe.
It just set a new Guinness World Record last week for the longest journey by an electric car after travelling 749 miles (1,205 km) on a single charge.
That record was set in the range-topping Lucid Air Grand Touring model, which is rated for up to 512 miles of EPA-estimated range. On the WLTP scale, it’s rated at 597 miles (960 km). Either way, it still crushed the estimates.
According to second-quarter sales data, released by Kelley Blue Book on Monday, the Lucid Air is still America’s best-selling luxury EV.
Lucid sold 2,630 Air models in Q2, up 10% from the previous year. Through the first half of 2025, Lucid Air sales are up 17% with 5,094 units sold.
Tesla, on the other hand, only sold 1,435 Model Ss during the quarter, 71% fewer than it did in Q2 2024. Tesla Model S sales in the US are down 70% through the first half of the year at 2,715.
Although Porsche Taycan sales were up 32% with 1,064 models sold, the significantly upgraded 2025 model year was expected to see even more demand. Porsche has 2,083 Taycans in the US this year, up just 1% from 2024.
Other luxury EV sedans, such as the BMW i5 (1,434), i7 (820), and the Mercedes EQS (498), experienced steep double-digit sales declines year-over-year.
And it’s not just electric luxury sedans. The Lucid Air is currently outselling many gas-powered vehicles in its segment.
Lucid’s first electric SUV, the Gravity, is also rolling out. Although only five were sold in the second quarter, Lucid is quickly scaling production. Lucid aims to produce 20,000 vehicles this year, more than double the roughly 9,000 it built in 2024.
Earlier today, Lucid’s interim CEO, Marc Winterhoff, confirmed during an interview with Bloomberg that the company expects higher Gravity output in the second half of the year.
The interview was at the grand opening of Panasonic’s new battery cell plant in De Soto, Kansas. Winterhoff said Lucid will start using new cells from the facility, but not until next year.
Lucid’s CEO stressed the importance of establishing a local supply chain, as policy changes under the Trump Administration are taking effect. Lucid and Panasonic are collaborating to localize EV materials, such as graphite. Last month, Lucid secured a multi-year supply agreement with Graphite One for US-sourced Graphite.
