A 13.6 megawatt (MW) offshore wind turbine with a record-breaking rotor diameter of 252 meters (827 feet) has debuted in China ahead of the country’s 20th Party Congress in Beijing, which opened yesterday.

World’s largest rotor diameter

The offshore wind turbine, which was announced on October 13 as having rolled off the production line in Fuqing City, east China’s Fujian Province, covers a swept area of 50,000 square meters (538,196 square feet), which is equivalent to seven soccer fields, the state-run People’s Daily reported on Saturday.

The wind turbine is now the largest single-unit turbine in the Asia-Pacific region, and its rotor diameter beats the previous title holder, Danish wind giant Vestas’ V236-15.0 MW turbine, which has a rotor diameter of 236 meters (774 feet).

The Chinese press reports that the new offshore wind turbine can generate 63.5 million kWh per year, and it’s capable of supplying 30,000 “three-person households” (the average Chinese household has three people) with power, according to Chinese media.

It is reported to be able to reduce coal by 19,000 metric tons and CO2 emissions by 48,000 metric tons.

The turbine maker isn’t explicitly named in Chinese state media reports, but it’s fairly apparent that it’s Beijing-headquartered multinational wind turbine maker Goldwind, as seen in the video below:

Electrek’s Take

Once I got past the awkward use of the words “impeller” and “propeller” used by Chinese media in English, I came to realize that Goldwind had broken the record for largest rotor diameter with this giant offshore wind turbine.

Let’s move past the political slant of this news to recognize that this is yet another major engineering feat that will help China move off fossil fuels. The whole world will benefit from that.

This new solar + storage site will help power the Las Vegas Strip

The Escape Solar and Storage project in Lincoln County, Nevada, will send clean power to big resort customers on the Las Vegas Strip. 

Reno-based Estuary Power, Escape’s developer, closed a $340 million financing package for the solar and storage project in late December 2024. 

Escape includes 185 megawatts (MW) of JinkoSolar PV capacity and 400 megawatt-hours (MWh) of Tesla battery storage capacity. 

Escape will supply 115 MW of solar and 400 MWh of battery energy storage to MGM Resorts International, 25 MW to Caesars Entertainment, 20 MW to Wynn Las Vegas, and 25 MW to Overton Power District under long-term agreements.

MGM Resorts International has set a goal to source 100% of its energy from renewables by 2030. Las Vegas resorts are required to comply with Nevada’s Renewable Portfolio Standard (RPS), which aims to increase the percentage of renewable energy to 50% by 2030. However, many resorts have already exceeded the 40% renewable energy requirement set by the state. The Venetian and Sands Expo and Convention Center partnered with NV Energy to procure renewable energy certificates to cover 100% of its electricity use.

Jill Daniel, CEO of majority woman-owned Estuary Power, said, “We look forward to supplying renewable energy to the iconic Las Vegas Strip and to our valued partner Overton Power District. We are thankful for the support of our financing partners in making the Escape project a reality.”    

The project is the first utility-scale solar project to be developed in Lincoln County, just north of Las Vegas, where it will generate nearly $80 million in tax revenue for the county over its life span. It’s currently under construction and will begin operating in 2025.

Las Vegas is second in the US for solar capacity per capita.

Aptera signs LG as battery supplier for its solar electric car

Aptera signs LG as battery supplier for its solar electric car

Aptera has signed a memorandum of understanding with LG Energy Solutions to supply batteries for its solar EV, which it says will start deliveries later this year.

Aptera is at CES this week, showing off it’s production-intent solar EV. We stopped by the booth for a few pictures, but beyond that, there wasn’t a lot new to announce.

But that changed today, as Aptera has now officially announced that it’s partnering with LG Energy Solutions as the exclusive supplier for battery cells for the Aptera solar EV, and CTNS for battery pack assembly.

Aptera said this partnership accomplishes three goals:

  • Enhance Aptera’s production capacity through a reliable and scalable battery supply chain. 
  • Solidify LG Energy Solution’s market presence as a trusted supplier.   
  • Strengthen CTNS’s reputation as a key manufacturing partner in the U.S. market. 

The agreement runs from 2025 to 2031, with LG supplying 2170-format cylindrical cells for battery modules and packs that will be assembled by CTNS and designed by Aptera.

The agreement covers 4.4GWh of battery capacity supply. Given that the Aptera has a 44kWh, 400-mile battery pack (at least at launch, other options might be available at some point), that’s enough for a total of 100,000 vehicles – quite a lofty goal for a rather small company that is relying on crowdfunding and has not yet shipped a car.

“This partnership represents a significant milestone in bringing our solar electric vehicles to market with the reliability and performance our customers expect. LG Energy Solution and CTNS bring unparalleled expertise, and we’re excited to work together to power the future of sustainable transportation.”

-Chris Anthony, Co-CEO of Aptera Motors

LG is one of the largest EV battery cell manufacturers in the world, and the largest outside China. The largest is CATL, but that company has found itself on a US blacklist.

As part of Aptera’s CES announcements, it reaffirmed that it plans to deliver its first vehicles by the end of this year, showed off the production configuration of its solar panels covering the hood, dash, roof and hatch of the vehicle, and said that it drove the car for 20 miles on a Las Vegas winter day and ended up with more charge than it had when it started. You can read more about Aptera’s CES show presence on our previous coverage here.

Aptera says it has 50,000 reservations for its vehicle, at $100 a pop (or $70, if you use our Aptera referral link). You can reserve an Aptera over at Aptera’s website.


But if you have an EV that *isn’t* covered with solar panels, maybe you can install solar panels on your home’s roof and charge your vehicle through solar anyway. Find a reliable and competitively priced solar installer near you on EnergySage, for free. They have pre-vetted installers competing for your business, ensuring high-quality solutions and 20-30% savings. It’s free, with no sales calls until you choose an installer.

Mazda is bringing this $20,000 Chinese EV overseas, but prices will be much higher

Mazda is bringing this ,000 Chinese EV overseas, but prices will be much higher

The electric Mazda 6 predecessor is headed for Europe this summer. Mazda’s EV starts at around $20,000 in China, but prices are expected to be significantly higher in Europe. Here’s what we know about the Chinese-made EV so far.

When will Mazda launch its $20,000 EV overseas?

Mazda unveiled the EZ-6 at the Beijing Auto Show alongside the Arata SUV last April. The EZ-6 is the all-electric predecessor to the Mazda 6 sedan.

Mazda’s Chinese joint venture, Changan Mazda, has been selling the EZ-6 in China since October. The electric sedan, which starts at just 139,800 yuan, or around $19,200, is already off to a hot sales start.

With nearly 2,500 models sold in November, its first sales month, Changan Mazda said the EZ-6 was among the top three mid-size new energy vehicle (NEV) sedans of joint ventures sold in China. According to Nikkei, Mazda will export the $20,000 EV to Europe starting this summer.

Based on Changan Auto’s hybrid platform, the EX-6 is available in EV and extended-range configurations in China. The all-electric version has a CLTC range of up to 600 km (372 miles).

The electric Mazda EZ-6 is 4,921 mm long, 1,890 mm wide, and 1,485 mm tall with a wheelbase of 2,895 mm, or about the size of a Tesla Model 3 (4,720 mm long, 1,922 mm wide, and 1,441 mm tall with a 2,875 mm wheelbase).

Inside, the EZ-6 has a modern cabin setup with 14.6″ infotainment and 10.1″ driver display screens. It also includes premium features like a 50″ AR head-up display and zero-gravity reclining seats.

The imported model will feature improved stability and control for high-speed driving on European roads. Mazda will showcase the updated EZ-6 at the Brussels Motor Show, which kicks off on Friday.

Like many automakers, Mazda is looking to meet the EU’s Zero Emission Vehicle (ZEV) mandates and avoid heavy fines. However, after the EU increased tariffs on Chinese EV imports to as much as 45.3%, Mazda will still have to pay the price.

China’s SAIC was hit the hardest with an extra 35.3% duty, while Geely (18.8%) and BYD (17%) were at the lower end. Other cooperating companies are subject to a 20.7% tariff, while non-cooperating automakers will have a duty of 35.3%.

Earlier this week, we learned Mazda will build a new module battery plant in Japan to supply its first dedicated EV. Although no details were revealed about the dedicated EV, Mazda said it will be powered by a new electric vehicle platform. The company aims to launch the new platform in 2027. Stay tuned for more.
