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.

Honda’s electric SUV took the US by storm, becoming the top-selling EV in the US outside of Tesla in the final three months of 2024. This year, Honda is making the Prologue even more attractive, upgrading it with over 300 miles of range. With 2025 Prologue models now arriving at dealerships, Honda wasted no time launching new deals this week.
2025 Honda Prologue EV deals and offers
After the first models were delivered last March, the Honda Prologue quickly became one of the best-selling electric vehicles in the US.
In the second half of 2024, the Prologue was the second best-selling electric SUV, trailing only the Tesla Model Y. This year, it boasts even more driving range and power.
Since Honda didn’t raise prices, it’s essentially a free upgrade (well, sort of). The 2025 Honda Prologue (2WD) now has a “top-class” EPA rating of 308 miles, up 12 miles from the outgoing model. It also packs 220 horsepower (+8) and 243 lb-ft of torque (+7).
The Prologue is still available in single-motor (2WD) and dual-motor (AWD) versions in three trims: EX, Touring, and Elite.
The AWD version now has a range of 294 miles (+13) for the EX and Touring trims and 283 miles (+10) for the Elite. It also now packs 300 horsepower (+12) and 355 lb-ft of torque (+25).
With DC fast charging speeds of up to 150 kW, the electric SUV can add 65 miles of range in around 10 minutes.
The 2025 Honda Prologue starts at $47,400, but with the $7,500 EV tax credit, prices could fall to under $40,000. And that’s for the EX single-motor version with up to 308 miles of range.
On Honda’s website, the 2025 Prologue is listed with a promotional rate of 2.99% APR for up to 60 months. Lease prices for the base model are not yet available, but the 2025 AWD EX is listed at $599 for 36 months with $4,299 due at signing.
Although the deals on the 2025 models are not nearly as good as the 0% financing and leases as low as $269 per month for the 2024 Prologue, Honda had to make up for the upgrades somewhere.
| Trim | Drive Configuration | Pricing | EPA Ratings | |||
| MSRP | After Federal EV Tax Credit | Plus $1,450 D&H |
Range Rating | MPGe Rating (City/Hwy/Combined) |
||
| EX | Single Motor (2WD) | $47,400 | $39,900 | $41,350 | 308 | 113 / 94 / 104 |
| EX | Dual Motor (AWD) | $50,400 | $42,900 | $44,350 | 294 | 108 / 90 / 99 |
| Touring | Single Motor (2WD) | $51,700 | $44,200 | $45,650 | 308 | 113 / 94 / 104 |
| Touring | Dual Motor (AWD) | $54,700 | $47,200 | $48,650 | 294 | 108 / 90 / 99 |
| Elite | Dual Motor (AWD) | $57,900 | $50,400 | $51,850 | 283 | 104 / 87 / 95 |
Honda is sweetening the deal with a charging package included in the Prologue’s price. You can choose from a free Level 2 home charger, a portable charging kit, or a $750 public charging credit.
The 2024 Honda Prologue is selling out fast with ultra-low lease and financing rates, while the 2025 model promises even more. Ready to try it out for yourself? You can use our link to find deals on the 2024 and 2025 Honda Prologue in your area today.

With its stock down more than 30% this year and revenue growth slowing, Jack Dorsey’s Block is going bigger in lending.
The company on Thursday said it secured approval from the Federal Deposit Insurance Corporation to originate loans through its banking subsidiary, Square Financial Services, allowing it to offer small-dollar consumer loans directly rather than relying on external banking partners.
It’s an expansion of Cash App Borrow, the company’s short-term lending product. But it comes at a time of increased concerns surrounding consumer credit, with President Trump’s expansive tariffs and widespread government job cuts raising talk of a potential recession.
Transaction losses in Block’s lending segment jumped 39% last quarter, and while the company claims its underwriting model is strong, small-dollar lending is inherently risky.
“Cash App Borrow is designed to provide short-term cash flow in a simple and accessible way when alternatives are notoriously expensive and difficult for consumers to navigate,” Block said in the press release. The company added that the average Cash App Borrow loan was under $100 and about a month in duration.
Block didn’t immediately provide a comment.
In getting approval to operate the lending business out of its own bank, Block says it will be able to offer the product nationwide.
Last month, Block reported quarterly results that missed Wall Street expectations, with revenue growing just 4.5% from a year earlier. The stock plunged 18%, its worst one-day drop since 2020.
Around the same time, Block rolled out Afterpay, its buy now, pay later product, on the Cash App card. Chief Financial Officer Amrita Ahuja told CNBC that the launch aimed to provide customers with more credit options, and positioned Cash App as a banking alternative for some customers. Block acquired Afterpay, which competes with Affirm, for $29 billion in early 2022.
Also this week, Block announced a big investment plan in artificial intelligence.
The company said on Wednesday that it will deploy Nvidia’s AI systems with its latest Blackwell chips to power open-source AI research. Block didn’t say what specifically it’s looking to achieve through its AI buildout, but noted in the press release that it will “start exploring novel solutions for our customers.”
![Kia's first electric van looks even better in person [Video]](https://i0.wp.com/electrek.co/wp-content/uploads/sites/3/2025/03/Kias-first-electric-van-PV5-1.jpeg?resize=1200,628&quality=82&strip=all&ssl=1)
Kia is launching its first electric van, the PV5, later this year. If you liked how it looked in pictures, wait until you see it in real life. A production PV5 was spotted in Korea for the first time, giving us a closer look at the futuristic van. See it for yourself in the video below.
Kia’s first electric van spotted in Korea
After teasing it for what seemed like forever, Kia finally took the sheets off the PV5 at its 2025 EV Day event last month.
With its hard-to-miss futuristic design, the PV5 is a near replica of the concept shown at CES last January. The mid-size electric van is set to kick off Kia’s new Platform Beyond Vehicle (PBV) strategy.
The PV5 will initially be available in Passenger, Cargo, and Chassis Cab setups, but with “unprecedented flexibility,” you can expect to see more options soon. Two of the first will be the PV5 Crew, with additional cargo securing options and a Wheelchair-Accessible Vehicle (WAV) version.
After that, Kia will follow it up with Drop Side, Box Van, Freezer, Box, and Prime variations. It plans to launch a Light Camper conversion.
With sales kicking off in the second half of 2025, Kia’s electric van was spotted in Korea for the first time without camouflage. A new video from HealerTV gives us a better idea of what to expect when the PV5 hits dealerships later this year.
The PV5 maintains its techy, almost ahead-of-its-time design. Two exterior body colors were shown: white and a darker grey or black. As the reporter notes, it actually looks like an upgrade from the concept.
Kia did what it could at the back so it didn’t look like a bus, giving it more of a rounded overall shape. You can see how it stands apart from most MPVs you see today.
Like the Volkswagen ID.Buzz, Kia’s PV5 looks more like a minibus. At 4,695 mm long, 1,895 mm wide, and 1,899 mm tall, Kia’s passenger electric van is slightly smaller than the European ID.Buzz model (4,712 mm long, 1,985 mm wide, 1,937 mm tall).
It will be available with 51.5 kWh and 71.2 kWh battery packs, good for up to 400 km (249 miles) WLTP range. The PV5 can also fast charge (10% to 80%) in about 30 minutes. In comparison, powered by an 84 kWh battery, the ID.Buzz now offers up to 293 miles WLTP range.
Kia will launch sales in Korea and Europe later this year, followed by other global markets in 2026. Pre-orders will open soon, so check back for prices.
