Expanding two power plants in Georgia and South Carolina with big, new reactors was supposed to spark a “nuclear renaissance” in the U.S. after a generation-long absence of new construction.
Instead, Westinghouse Electric Co.’s state-of-the-art AP1000 design resulted in long delays and steep cost overruns, culminating in its bankruptcy in 2017. The fall of Westinghouse was a major blow for an industry that the company had helped usher in at the dawn of the nuclear age. It was Westinghouse that designed the first reactor to enter commercial service in the U.S., at Shippingport, Pennsylvania in 1957.
Two new AP1000 reactors at Plant Vogtle near Augusta, Georgia started operating in 2023 and 2024, turning the plant into the largest energy generation site of any kind in the nation and marking the first new operational nuclear reactor design in 30 years. But the reactors came online seven years behind schedule and $18 billion over budget.
In the wake of Westinghouse’s bankruptcy, utilities in South Carolina stopped construction in 2017 on two reactors at the V.C. Summer plant near Columbia after sinking $9 billion into the project.
But today, interest in new nuclear power is reviving as the tech sector seeks reliable, carbon-free electricity to power its artificial intelligence ambitions, especially against China. Westinghouse emerged from bankruptcy in 2018 and was acquired by Canadian uranium miner Cameco and Brookfield Asset Management in November 2023
The changed environment means South Carolina sees an opportunity to finish the two reactors left partially built at V.C. Summer eight years ago. The state’s Santee Cooper public utility in January began seeking a buyer for the site to finish reactor construction, citing data center demand as one of the reasons to move ahead.
“We are extraordinarily bullish on the case for V.C. Summer,” Dan Lipman, president of energy systems at Westinghouse, told CNBC in an interview. “We think completing that asset is vital, doable, economic, and we will do everything we can to assist Santee Cooper and the state of South Carolina with implementing a decision that results in the completion of the site.”
Tech as a nuclear catalyst
The United States has tried to revive nuclear power for a quarter century, but the two reactors in Georgia mark the only entirely new construction across that period despite bipartisan support under every president from George W. Bush to Donald Trump.
A fresh start was supposed to have begun more than a decade ago, but was choked off by a wave of closures of older reactors as nuclear struggled to compete against a boom of cheap natural gas created by the shale revolution.
“We went from an environment in the aughts of rising gas imports and rising gas prices to fracking technology unlocking quite a bit of affordable natural gas here in the U.S., and companies didn’t really value the firm clean attribute of nuclear back then,” said John Kotek of the Nuclear Energy Institute, an industry lobby group, and former assistant secretary at the Office of Nuclear Energy under President Barack Obama.
What’s different in 2025 is the tech sector’s voracious appetite for power translating into a willingness to pay a premium for nuclear. But recent investments in nuclear have focused on restarting abandoned reactors and attempting to bring online smaller, next-generation modular reactors that many believe are the future, if they can be designed and built more cheaply.
The troubled nuclear plant at Three Mile Island near Harrisburg, Pennsylvania that almost melted down in 1979 is expected to resume operations in 2028 after owner Constellation Energy struck a power purchase agreement with Microsoft last September. Constellation wants to restart Unit 1, which shut for economic reasons in 2019, not the Unit 2 reactor that was the site of the accident.
Alphabet and Amazon invested in small nuclear reactors a month later. Meta Platforms, owner of Facebook and Instagram, asked developers in December to submit proposals for up to 4 gigawatts of new nuclear power to meet the energy needs of its data centers.
But while the recent focus in the U.S. has been on restarts and commercializing small reactors, Lipman said the extent of potential demand that has emerged from data centers over the past year has led to renewed interest in Westinghouse’s large AP1000 reactor design.
In any event, there are no operational small reactors in the U.S. today, though startups and industry stalwarts, including Westinghouse, are racing to commercialize the technology. And there only so many shuttered plants in the U.S. in good enough shape to potentially be restarted.
Gargantuan undertaking
Meanwhile, meeting the demand for power is a gargantuan undertaking. Meta’s need for new nuclear power, for example, is nearly equivalent to the entire 4.8 gigawatts of generating capacity at the Vogtle plant, enough to power more than 2 million homes and businesses. Large nuclear plants with a gigawatt or more of capacity — the size of the AP1000 — will be essential to power large industrial sites like data centers because of their economies of scale and low production costs once they’re up and running, according to a recent Department of Energy report.
Georgia Gov. Brian Kemp called for another reactor at Vogtle the same day he dedicated the plant expansion in May 2024. Southern Company CEO Chris Womack believes at least 10 gigawatts of large nuclear are needed. Southern is the parent company of Georgia Power which operates Vogtle.
“The people that are going to own and operate AP1000s traditionally are investor-owned electric utilities,” Lipman said. “When they look at the marketplace for a large reactor, AP1000 is where they turn because it’s got a license, it’s operational.”
Still, nobody in the U.S. is on the verge of signing an order for a new AP1000, he said. Westinghouse is focused on deploying reactors in Eastern and Central Europe, where nuclear projects are seen as a national security necessity to counter dependency on Russian natural gas after the invasion of Ukraine.

In addition to the two units in Georgia, Westinghouse also has four operational reactors in China.
But South Carolina’s search for someone to complete the partially built reactors at V.C. Summer will likely draw investment from Big Tech “hyperscalers” building data centers, and large manufacturers like the auto industry, Lipman said.
“That kind of asset attracts industry that relies on 24/7, 365 energy and that’s what you get with an AP1000,” Lipman said. There are ongoing discussions within the industry about whether the tech sector might act as a developer that invests capital in the upfront costs of building new plants, he said.
What went wrong in the South
Any attempt to build new AP1000s in the U.S. again will almost certainly meet with skepticism after the experiences in South Carolina and Georgia.
Lipman said the challenges that the AP1000 construction faced in the South have been resolved. Back then, Westinghouse agreed to the projects before the reactor design was complete, and supply chains weren’t fully formed due to a long period in which U.S. construction was dormant, he said.
“One big lesson learned, maybe the big lesson learned, is designs need to be complete before they hit the field, meaning they have to be shovel ready,” Lipman said. The design for the AP1000 is complete and Westinghouse has its supply chain in place, he said.
“We have winnowed over our list of suppliers,” Lipman said. “They are supporting us globally, and so it’s really easy then to have them make more equipment for deployment.”
“You’re getting economies of scale,” he said.
Ironically, given the overruns in Georgia, the original aim of AP1000 was reduce costs by creating a standardized design that requires less construction materials compared to older reactor types, Lipman said. Components of the plant are prefabricated before being assembled on site, he said.
“You basically assemble, kit-like, major portions of the plant in a modular fashion, a bit like aircraft and submarines are done,” Lipman said. “That was not fully shaken out completely at the Vogtle site.”
The Department of Energy under the Biden administration argued in a September report that future AP1000 builds should be less expensive because they won’t incur costs associated with the first-of-a-kind project in Georgia. Support from the department’s loan office, tax credits under the Inflation Reduction Act, and shorter construction timelines would substantially reduce costs, according to the report.
Trump plans for nuclear
While President Donald Trump is supportive of nuclear, it’s unclear whether the industry will receive support through DOE loans and the investment tax credit under the Inflation Reduction Act (IRA). Those tools were pillars of the Biden administration’s plan to help reduce the cost of new AP1000s.
Trump issued an executive order on his first day in office that directed federal agencies to remove obstacles to development of nuclear energy resources. The same order, however, paused all spending under the IRA. Two weeks later, Secretary of Energy Chris Wright made commercializing “affordable and abundant nuclear energy” a priority in a Feb. 5 order.
“The long talked about nuclear renaissance is finally going to happen, that is a priority for me personally and for President Trump and this administration,” Wright told CNBC in a Feb. 7 interview. Wright was previously a board member of Oklo, a nuclear startup that aims to disrupt the status quo of the industry by deploying micro reactors later this decade.
Wright emphasized commercializing small reactors and said private capital would drive the construction of new plants. Before the November election, Trump was skeptical of building large reactors, citing the cancelled project in South Carolina.
“They get too big and too complex and too expensive,” he told Joe Rogan in an October interview.
Lipman said the first Trump administration was pro-nuclear, and he expects the president will support the industry in his second term.
“If there’s going to be gigawatt scale deployment in the U.S., decision making needs to accelerate,” Lipman said. “The business model, the investment climate, any legislative changes that might be in the offing at the state level or the federal, now is the time to address those pertinent issues.”

The Tesla Solar Roof tiles are still alive, but the product is on the back burner at Tesla as it failed to achieve its promises.
When launching the solar roof in 2016, CEO Elon Musk presented it as a critical product to accelerate solar power deployment, as it opens up the market to people who want to go solar but also need to replace their roof soon.
He said that he aimed for Tesla to produce 1,000 new solar roofs per week by the end of 2019.
However, Tesla didn’t reach volume production of the solar roof tiles until 2020, and even then, it was at a fraction of the deployment it was aiming for.
In 2022, Electrek reported that Tesla installed solar roofs for the first time and confirmed that the Company deployed 2.5 MW of solar roofs during the second quarter of 2022, equivalent to approximately 23 roofs per week, which is far short of its goal.
Since then, Tesla has even further pulled back its solar effort – and even stopped reporting its solar deployment.
Many people are asking what it means for the solar roof, which Musk touted as a revolutionary product.
In 2023, we reported that Tesla began phasing out its solar business, particularly its in-house installations.
Tesla shifted its focus on deploying Powerwalls and solar inverters through third-party installers.
The same thing is happening with Tesla’s solar roof tiles. The company appears to be giving up on installing them itself, but some installations are still happening with third-party certified installers.
Tesla doesn’t even give online quotes on its solar roof anymore and has people submit requests for quotes through third-party installers:
“In order to receive pricing and product information, Tesla will share your contact information with a Tesla Certified Installer.”
We are hearing less about solar roof installations lately, as Tesla has gone virtually silent on the program; however, some ongoing installations are still being carried out by third-party installers.
Weddle and Sons Roofing just posted about a new 20 kW Tesla Solar Roof installation in Topeka, Kansas:
It’s challenging to determine the exact deployment rate of the solar roof, but based on our checks with a few installers, it doesn’t appear to have increased since 2022.
Tesla-certified installers are even convincing potential buyers to opt for a regular roof with solar panels instead of a solar roof. Potential buyer Jeff Betty shared this text from an unnamed installer:
This is not entirely surprising, as the primary issue with the Tesla Solar Roof tiles is their pricing. Tesla aimed for the solution to be competitive with higher-end roofing options, but it remains expensive and much less affordable than many durable roof options, plus solar panels.
Electrek’s Take
In short, the Tesla Solar Roof is still alive, but it’s nowhere near the revolutionary product Tesla claimed it would be.
Instead, it has become a very niche higher-end roofing product that Tesla deploys in very low volume through third-party installers.
It’s not in any way a significant part of Tesla’s energy business, which is now almost entirely Megapacks and Powerwalls.
While Tesla’s solar roof is not for everyone, now is a great time to go solar with rooftop solar panels.

Retrospec Valen Rev+: A fat tire e-bike with the spirit of an all-terrain scrambler [Video]
![Retrospec Valen Rev+: A fat tire e-bike with the spirit of an all-terrain scrambler [Video]](https://i0.wp.com/electrek.co/wp-content/uploads/sites/3/2025/04/DSC08478.jpg?resize=1200,628&quality=82&strip=all&ssl=1)
For the Valen Rev+, Retrospec managed to get the best out of that iconic moto-style scrambler spirit and put it into a comfortably handling fat tire e-bike while also keeping the performance bits that make it fun, and the best part is it comes at a reasonable price of just under $1,800
Aside from the looks and price this bike has a unique fun factor that comes from a combination of a few key components here.
One is the 20 by 4.0 inch Fat MTB tires with puncture protection and reflective sidewalls. Aside from these tires offering an extra layer of protection and suspension, Retrospec’s decision to offer wide tires also gives way more stability than a typical bike tire, which makes going through ruts, mud, or sand pretty effortless.
The second key component is the front suspension, which is fully adjustable and has 100mm of travel. Combined with the extra suspension from the fat tires, as mentioned earlier, this makes otherwise challenging terrain turn into fun detours that you’ll likely go out of your way to use.
The third component is the 750w rear hub motor, which gives the bike a 28 mph assisted top speed. Combined with the secure handling and added front suspension, the Valen Rev+ is the kind of bike you want to plan an adventure with. Whether that’s a dirt road shortcut on your commute or a day to the beach, the comfortable long seat makes it hard to say no to a trip with the Valen Rev+
On the practical side, Retrospec put some significant thought into the design and build of this bike to ensure that riders are cared for with those often less thought of yet still essential features. Starting with the battery, the fully integrated 720Wh battery uses LG 21700 cells for a total of 68 miles of range when fully charged. In addition, the battery is lockable and easily removable for both on- and off-bike battery charging. It’s also seamlessly integrated into the bike’s frame, making for a clean look.
For safety, Retrospec added Tektro hydraulic disc brakes with e-bike-specific rotors, which is an important upgrade, considering an improved rotor typically allows for better heat dissipation and better overall performance. There are also Integrated front and rear lights with 100 Lux illumination for the front. Safety aside, the design here for the front light looks amazing.
For the less thought-of yet essential features, Retrospec included an easy-change rear wheel removal system that uses braze-ons located at the lower part of the bike, so there’s no need to remove zip ties. Unlike other e-bikes, the Valen Rev+ kept it simple with the same axel nut for both the front and rear which means fewer tools, but what makes the process itself a lot easier is not having to wrestle the chain when re-installing the wheel thanks to the chain hanger.
One of the great feelings of the Retrospec Valen Rev+ e-bike is how simple yet stylish it is; the display is a center-mounted color display with controls on the left-hand side of the handlebars. The control panel has only three buttons, so it’s as simple as it gets. With the up or down control, you can change through 6 levels of pedal assist, but if you’re looking for more control, you can also use the controls on the right side of the handlebars to cycle through the eight speeds on the Shimano Altus derailleur.
For how comfortable the moto-inspired Valen Rev+ is, it also feels great to pedal on in case you’re looking for more exercise and want to opt for the pedal assist rather than the throttle only. Unlike other e-bikes on the market, Retrospec’s Rev+ makes riding very approachable. For those who are newer to riding, that long seat and wide tires add a level of stability, making the overall learning experience much more enjoyable. With how comfortable the bike rides, it might make you think more about leaving the car at home more often and opting for the bike paths.
For those looking to get as much fun as possible out of an e-bike aside from the fat tires and front suspension, Retrospec’s BMX style handlebars offer excellent geometry and height that gives you much more control over the bike in case you wanna stand up and tackle some of the more challenging trails. In addition, if you’re looking to forget pedaling altogether, you could even choose to get the optional footpeg accessories, which, combined with the BMX-styled handlebars, will make the bike much more functional for off-road riding.
Overall, Retrospec seems to have put a lot of effort into bringing that scrambler moto spirit into a comfortable bike with loads of features that other manufacturers haven’t quite nailed down. From the easy rear wheel removal to the BMX-styled handlebars and comfortable long seat, it’s a very approachable and easy-to-maintain e-bike that can still rip on trails for those who want to tackle more of that tough off-road terrain.

![This is it: Mazda EZ-60 crossover interior revealed ahead of global launch [video]](https://i0.wp.com/electrek.co/wp-content/uploads/sites/3/2025/04/Screenshot-2025-04-19-at-6.35.22 AM.png?resize=1200,628&quality=82&strip=all&ssl=1)
We got our first look at the new-for-2026 Mazda EZ-60 electric crossover just last week, but Mazda played coy with the interior, leading many in the media (including us) to believe that the interior would be pretty similar to the EZ-6 sedan‘s. We were wrong.
I’ll cut right to the chase. The new Model Y rival from Mazda is coming for the Y’s old sales crown with a starkly elegant 26.45-inch 5K ultra-wide display with dual screens and (get this) a massive 100″ (!) augmented reality heads-up display (AR-HUD) that projects key driving information onto the windshield, alerting the driver of pedestrians, speed limits, etc.
You can check it out for yourself, below.
Mazda EZ-60 interior revealed
As you can see, the interior largely eschews buttons, knobs, or physical interfaces of any kind in favor of touchscreens. Those screens enable EZ-60 drivers and passengers to control and adjust a 23-speaker, 7.1.4-channel Dolby Atmos audio system, while a separate touchscreen in the rear allows drivers passengers to adjust climate and entertainment settings for themselves.
Other interior features include super-slick digital wing mirror displays (the exterior “side mirrors” are aerodynamic cameras), and fully twenty kid- and family-friendly storage compartments sprinkled liberally throughout the vehicle. A relatively small 350-liter (12.3 cu ft) rear trunk expands to 2,036 liters (71.9 cu ft) with the seats folded flat. A 126-liter frunk (4.4 cu ft, or about the size of the mini fridge in your college dorm) adds extra practicality.
The electric Mazda SUV itself is built on the Changan EPA1 platform, and is believed to be powered by an 80 kWh battery good for 295 miles of WLTP range, and a 93 kW charging speed that can take the EZ-60 from 30 to 80% charge in a little over 30 mins.
Following the crossover’s Chinese launch – officially slated for April 23rd. Changan Mazda plans to release the EZ-60 in overseas markets under the Mazda CX-6e nameplate.
Electrek’s Take
Mazda is on a hot streak right now – and not just in China, but in the US as well. The brand’s near-premium positioning is perfect, targeting middle class buyers who are willing to pay a premium to drive a vehicle with better fit and finish than the Ford, Chevy, and Stellantis offerings – but not enough of a premium to justify a move into Acura/Volvo territory. And, frankly, no one in the industry is doing paint as well as Mazda right now. Not until you start doubling the Mazda’s MSRPs, anyway.
Here’s hoping this one comes to the US.
