The world’s most powerful wind turbine has broken a world record for the most power produced by a single turbine over a 24-hour period.
Danish wind giant Vestas’s V236-15.0 MW prototype produced 363 megawatt-hours of power in a 24-hour period.
Vestas installed the 15 megawatt (MW) offshore wind turbine at the Østerild National test center for large wind turbines in Western Jutland, Denmark, in December 2022, where it’s been tested and verified extensively. It reached its full 15 MW power rating for the first time in April.
Jesper Uth, senior director of test & validation at Vestas, said on LinkedIn, “Seven months into testing, we are excited to see the performance of the turbine at full power at continuously high wind. The verification campaign will continue to achieve the type certification and further demonstrate what a high-quality machine can deliver over time.”
The V236-15.0 MW was introduced to the market in February 2021. It has a rotor diameter of 774 feet (236 meters) and a wind-swept area of 470,845 square feet (43,743 square meters). It features 379-foot (115.5-meter) blades. And at 919 feet (280 meters), it’s also the world’s tallest wind turbine.
A single V236-15.0 MW is capable of producing 80 GWh per year. That’s enough to power around 20,000 European households and save more than 38,000 tonnes of carbon dioxide, the equivalent of removing 25,000 passenger cars from the road annually.
The world’s most powerful wind turbine has been selected for New York’s Empire Wind 1 and Empire Wind 2 offshore wind projects, which are expected to deliver power in the mid-2020s, and New Jersey’s Atlantic Shores, which is expected to come online in 2027.

Today was the official start of racing at the Electrek Formula Sun Grand Prix 2025! There was a tremendous energy (and heat) on the ground at NCM Motorsports Park as nearly a dozen teams took to the track. Currently, as of writing, Stanford is ranked #1 in the SOV (Single-Occupant Vehicle) class with 68 registered laps. However, the fastest lap so far belongs to UC Berkeley, which clocked a 4:45 on the 3.15-mile track. That’s an average speed of just under 40 mph on nothing but solar energy. Not bad!
In the MOV (Multi-Occupant Vehicle) class, Polytechnique Montréal is narrowly ahead of Appalachian State by just 4 laps. At last year’s formula sun race, Polytechnique Montréal took first place overall in this class, and the team hopes to repeat that success. It’s still too early for prediction though, and anything can happen between now and the final day of racing on Saturday.
Congrats to the teams that made it on track today. We look forward to seeing even more out there tomorrow. In the meantime, here are some shots from today via the event’s wonderful photographer Cora Kennedy.

The numbers are in and they are all bad for Tesla fans – the company sold just 5,000 Cybertruck models in Q4 of 2025, and built some 30% more “other” vehicles than it delivered. It just gets worse and worse, on today’s tension-building episode of Quick Charge!
We’ve also got day 1 coverage of the 2025 Electrek Formula Sun Grand Prix, reports that the Tesla Optimus program is in chaos after its chief engineer jumps ship, and a look ahead at the fresh new Hyundai IONIQ 2 set to bow early next year, thanks to some battery specs from the Kia EV2.

Tesla has launched its new Oasis Supercharger, the long-promised EV charging station of the future, with a solar farm and off-grid batteries.
Early in the deployment of the Supercharger network, Tesla promised to add solar arrays and batteries to the Supercharger stations, and CEO Elon Musk even said that most stations would be able to operate off-grid.
While Tesla did add solar and batteries to a few stations, the vast majority of them don’t have their own power system or have only minimal solar canopies.
Back in 2016, I asked Musk about this, and he said that it would now happen as Tesla had the “pieces now in place” with Supercharger V3, Powerpack V2, and SolarCity:

All of these pieces have been in place for years, and Tesla has now discontinued the Powerpack in favor of the Megapack. The Supercharger network is also transitioning to V4 stations.
Yet, solar and battery deployment haven’t accelerated much in the decade since Musk made that comment, but it is finally happening.
Tesla has now unveiled the project and turned on most of the Supercharger stalls:
The project consists of 168 chargers, with half of them currently operational, making it one of the largest Supercharger stations in the world. However, that’s not even the most notable aspect of it.
The station is equipped with 11 MW of ground-mounted solar panels and canopies, spanning 30 acres of land, and 10 Tesla Megapacks with a total energy storage capacity of 39 MWh.
It can be operated off-grid, which is the case right now, according to Tesla.
With off-grid operations, Tesla was about to bring 84 stalls online just in time for the Fourth of July travel weekend. The rest of the stalls and a lounge are going to open later this year.
Electrek’s Take
This is awesome. A bit late, but awesome. This is what charging stations should be like: fully powered by renewable energy.
Unfortunately, it will be much harder to open those stations in the future due to legislation that Trump and the Republican Party have just passed, which removes incentives for solar and energy storage, adds taxes on them, and removes incentives to build batteries – all things that have helped Tesla considerably over the last few years.
The US is likely going to have a few tough years for EV adoption and renewable energy deployment.
