Cambridge, Massachusetts, has signed the largest-ever virtual power purchase agreement (VPPA) by a US city to help build a utility-scale solar farm in Illinois.

The 135 megawatt (MW) project on 800 acres in Champaign County, called Prairie Solar, will add clean energy to the grid, and Cambridge will earn renewable energy certificates (RECs) for making it possible.

These credits will benefit residents and businesses enrolled in Cambridge’s Community Electricity Program, which already offers stable and competitive electricity rates. This marks Cambridge’s second major renewable energy deal, following last year’s VPPA for a wind farm in North Dakota. Together, these projects are accelerating the city’s efforts to cut carbon emissions more effectively than waiting for the Massachusetts grid to go fully renewable by 2050.

Dennis Carlberg, chief sustainability officer at Boston University, said, “Since the New England Grid is one of the cleanest in the country, and these projects are in grids slower to transition, they should reduce nearly twice the global greenhouse gas emissions than if the same projects were located in the greening New England grid. This is truly remarkable work that I hope others will replicate.”

Why solar in Illinois?

The Prairie Solar project, expected to come online in summer 2026, will be built near a former coal mine. Illinois residents will benefit from new jobs, local investment, and improved air quality on top of the clean electricity the project will generate.

Julie Wormser, Cambridge’s chief climate officer, put it this way: “Preventing carbon emissions in Cambridge or Illinois has the exact same impact on the global climate. It will allow us to make a bigger difference more quickly and cheaply than, say, pursuing smaller rooftop solar within city limits while providing local benefits to people in Illinois.”

This approach also helps Cambridge reach its sustainability goals without being limited by its small size and dense urban footprint. With 120,000 people in just 6.5 square miles, there isn’t enough space for the city to generate all its own power locally. That’s where strategies like VPPAs come into play.

Ellen Katz from Cambridge’s Department of Public Works explained the logic: “Renewable projects, like this VPPA, make the most difference because they replace more carbon-intensive fuel sources, like coal, compared to Massachusetts, where most of the electricity is fueled by natural gas.”

How Cambridge’s VPPA works

Cambridge’s 50 MW virtual power purchase agreement doesn’t send electricity directly to the city. Instead, it commits to purchasing renewable energy certificates from the project, which helps the developer secure financing to build the solar farm. The Prairie Solar project will be owned and operated by renewable company MN8 Energy, while Sustainability Roundtable Inc. facilitated the deal through their Net Zero Consortium for Buyers.

When Prairie Solar comes online, more than half (55%) of the power in the Standard Green option in Cambridge’s Community Electricity Program will come from renewable energy. Residents can already opt to buy 100% renewable power at a slightly higher rate.

Cambridge’s clean energy strategy

Cambridge isn’t stopping at VPPAs. The city continues to invest in its own backyard with energy-efficient buildings, geothermal systems, and solar installations. Local programs are also helping residents and businesses phase out fossil fuel use.

The city has committed to reaching net-zero emissions by 2050, and a big chunk of its carbon pollution comes from buildings and transportation. While the Massachusetts grid is on track to be 100% renewable by 2050, Cambridge is speeding up the transition by supporting new solar and wind projects where they’re needed most.

Cambridge City Manager Yi-An Huang summed up: “We’re increasing the amount of renewable energy getting built – whether it’s here in Cambridge or other parts of the country.”

HappyRun G300 Pro review: It’s an electric motorcycle with pedals and I’ve got some thoughts

HappyRun G300 Pro review: It's an electric motorcycle with pedals and I've got some thoughts

The HappyRun G300 Pro is the epitome of an out-of-class electric bike. That is to say, it has many of the components of an electric bicycle, key among them the functional pedals, but its extremely high power and speed place it well outside the limits of traditional e-bike classifications. The result? Basically, an electric motorcycle with pedals. And I’ve got some thoughts about that.

But before I dive into those, this is one of those rides that you’ll want to see in action. Check out my review video below. Then keep reading for the full details.

HappyRun G300 Pro Video Review

HappyRun G300 Pro Tech Specs

  • Motor: 3,000W continuous and 6,500W peak-rated rear hub motor
  • Top speed: Up to 50 mph (80 km/h)
  • Range: Claimed up to 70 miles (121 km)
  • Battery: 72V 30Ah (2,160 Wh)
  • Weight: Heavy (well off the scale on my 100 lb scale)
  • Brakes: Quad-piston DYISLAND hydraulic disc brakes
  • Front suspension: inverted front fork
  • Rear suspension: “Yopi Box” rear spring suspension
  • Extras: Looks like a Sur Ron or Talaria-style bike, color LED display, included fenders, LED headlight and tail light with turn signals, very nice kickstand, two color options available.

What is this even for?

Despite looking like a bicycle in some regards, I definitely felt wrong using this in the bike lane. That meant for 95% of my road riding, I was simply in the lane like a motorbike. The only times I would use the bike lane were when I could see it was completely empty, and it was basically just a shortcut past the stopped traffic at red lights. And even then, it just didn’t sit right with me. I’m an e-biker and I live a car free life, so the safety of bike lanes is an important issue for me. I’m not going to jeopardize other riders or even make them feel unsafe in the tiny little sliver of asphalt that is supposed to feel like home for us, and so I ride this thing in the road when I’m on the road.

That being said, I don’t even think the road is the right place for this bike. Where it really shines is off-road. Between the long travel suspension, the enduro-style seat, and the unnecessarily high power for commuting purposes, the HappyRun G300 Pro is at home in the dirt and on the trails. In fact, I even enjoyed overlanding on it, going places where trails couldn’t take me. It felt like a great exploring-the-outdoors type of ride!

If you watch my video above, you’ll see that this type of riding, recreational and exploring, is where the HappyRun G300 Pro really came into its own, and I think that’s precisely where it belongs. Just like how Sur Rons and Talarias shouldn’t really be taking over the streets, but instead should stick to the dirt trails they excel at, this is a great bike for that purpose. You’ll also notice in the video that I prefer to wear my motorcycle gear when I ride these types of bikes, and I’d make that recommendation to anyone else. A t-shirt and a bike helmet just don’t feel like enough here.

With that in mind, the included bicycle pedals start to seem superfluous though, and I really only pedaled at slow speeds, or when ghost pedaling because a cop was in the area and I didn’t want to get a bike impounded before I was even done reviewing it. So if you ask me, it doesn’t really need the pedals, and it doesn’t even really need the roads.

What about the build?

The HappyRun G300 Pro is an interesting mix of quality parts and merely acceptable parts. Nothing about it seemed terrible or dangerous, and a few components like the Sur Ron kickstand actually impressed me. But then the use of a bicycle-level handlebar stem and budget-level shocks seems to undercut that message.

On the other hand, the massive 72V 30Ah battery is huge and likely more than most people would need. I’d have preferred to see it being UL-listed, but I guess at least it claims to be underwritten by some Chinese insurance agency. I guess that’s better than nothing?

The geometry actually kind of sticks the landing, at least for me and my 170 cm (5’7″) height. The saddle is plenty comfortable, though my off-roading had me out of the saddle much of the time anyway and letting my legs join the full-suspension to better absorb the terrain.

What’s my verdict?

Here’s the thing: nothing about this bike is top shelf, but it still offers an incredibly fun, solid feeling ride. The power is more than most people need, the speed is faster than most people should ride (especially on trails), and the battery has more capacity than most people would require. So it’s not like they’re cutting corners on performance.

Some components could have been beefed up, and the decision to lean more towards bicycle-level components does make me question what a few years of hard off-road riding could do to this bike. But when used correctly, in an area where the bike is meant to be used (i.e., not where it legally isn’t allowed to be ridden), then it seems to fulfill the role of a fun adventure-style bike. At a price of $2,599 (or $100 off with the code ELECTREK), it significantly undercuts the cost of a Sur Ron or Talaria bike while giving a similar type of ride, even if the components don’t live up to the level of those costlier light electric dirt bikes.

My biggest worry, though, isn’t about the bike, but rather the potential for it to be misused. Look, it’s a fun ride and offered me more performance than I needed for all the different types of riding I tested it with. But like any bike, it has to be used in its element. We don’t blame the hammer if someone hits their thumb while driving a nail, and we shouldn’t blame the bike if someone wraps it around a parking meter. But it also really shouldn’t be used in that kind of environment, and it definitely shouldn’t be used in a way that could put others at risk.

It’s a fun ride for exploring, but this level of power requires some serious personal responsibility. If you’re a parent wondering if you should get this for your 16-year-old, the answer is probably “No.” But if you’ve got a fully developed prefrontal cortex and you want a fast and powerful ride without breaking the bank, this might be a decent option.

Toyota breaks ground on the first independent Lexus EV plant in China

Toyota breaks ground on the first independent Lexus EV plant in China

Toyota is finally getting into the game in the world’s largest EV market. On Friday, Toyota officially broke ground on the new Lexus EV plant in Shanghai, its first fully owned manufacturing facility in China and the second in the region, following Tesla.

Toyota is building a new Lexus EV plant in China

After officially announcing it would open a wholly-owned EV plant in China to build new energy vehicles (NEVs) for its luxury Lexus brand in February, Toyota is already kicking off construction.

Toyota finalized a deal with the Shanghai government on April 22 to build the facility. Just over two months later, the company is making swift progress in what’s being called “Lexus speed” locally.

The facility, which spans roughly 1.13 million square meters, could be one of Toyota’s most important to date. Following Tesla, which broke ground on its Shanghai Gigafactory in early 2019, Toyota is the second foreign automaker to construct a wholly owned auto plant in Shanghai.

Construction is expected to be completed in August 2026, with production set to commence in 2027. According to local news outlet The Paper, the facility will be capable of producing up to 100,000 NEVs annually.

Although Toyota will use the new standalone Lexus plant to accelerate EV output, it will also be used to develop vehicles tailored to local buyers.

Since the plant is overseas in Shanghai Bay Area Hi-Tech Zone, Toyota established a “two-line collaboration,” which will enable “24-hour uninterrupted work.”

The first Lexus electric vehicle is scheduled to roll off the assembly line in 2027. Much like for Tesla, local authorities are providing generous support.

For example, the Jinshan District Investment Promotion Office introduced an “order-based” business agreement, addressing Toyota’s “demand list” in advance.

Electrek’s Take

Toyota will use the new Lexus plant as it looks to keep pace with BYD and other domestic EV leaders in China. After launching several new vehicles over the past few months, the Japanese automaker is already starting to gain some traction.

After launching the bZ3X in March, Toyota’s electric SUV was the best-selling foreign EV in China in April, its second month on the market.

Toyota’s electric SUV already outsold the Volkswagen ID.3, ID.4 Crozz, and BMW i3. The bZ3X is Toyota’s most affordable EV, launched in China with a starting price tag of just 109,800 yuan, or about $15,000.

Earlier this month, Toyota launched another electric SUV, the bZ5. The bZ5 is about the size of Tesla’s Model Y, but costs about half as much in China, starting at 129,800 yuan ($18,000).

These electric SUVs are significantly more advanced and feature-rich than the Toyota vehicles we’re accustomed to seeing. They feature advanced smart driving tech, massive touchscreens, and some added bonuses like a built-in refrigerator.

During its EV Tech Day event earlier this month, Toyota’s joint venture, GAC Toyota, announced partnerships with several “car industry bigwigs,” including Huawei, Xiaomi, and Momenta.

Can Toyota keep pace in China with an intensifying EV price war and influx of new low-cost domestic rivals? So far, the new vehicles are helping.

In April, Toyota’s sales in China increased by 20% compared to the same period last year, with 142,754 vehicles sold. Through May, Toyota’s sales are up 7.7% with 530,000 vehicles sold.

Tesla hires Head of Autonomy from GM's failed self-driving startup

Tesla has hired Henry Kuang, the former ‘Head of Autonomy’ at GM’s failed self-driving startup, Cruise.

The automaker has had difficulties with turnover in its Autopilot and self-driving division.

Tesla has lost many leaders over the years and the departures have ramped up as of late. Here’s a list of Tesla leaders related to Autopilot and self-driving efforts who have left the company:

Name Role Departure
Sterling Anderson Head of Autopilot Jan 2016
Chris Lattner VP, Autopilot Software Jun 2017
Jim Keller VP, Autopilot Hardware Apr 2018
Andrej Karpathy Dir. AI & Autopilot Vision Jul 2022
Zheng Gao Dir. Autopilot Hardware Dec 2024
Marc Van Impe Global Vehicle Automation & Safety Policy –2024
Drew Baglino SVP Powertrain & Energy Engineering Apr 15, 2024
David Lau VP, Software Engineering Early Apr 2025
Milan Kovac VP, Optimus Engineering (ex-Autopilot engineer) Jun 6, 2025
Omead Afshar Senior Executive (AI/Robotics/Roadmap) Late Jun 2025

Meanwhile, there haven’t been many high-profile hires as Tesla prefers to hire younger, more junior engineers and promote within.

Amidst brand damage in recent years, Tesla has also faced more difficulties securing top hires. A recent leaked recording from a Tesla training session confirmed that the automaker has had a culture problem within its workforce.

However, Electrek has found a rare new executive-level hire in Tesla’s self-driving division.

According to his LinkedIn profile, Henry Kuang has been hired by Tesla as “Director of AI and Deep Learning for Autonomous Driving.”

Kuang was a long-time Facebook engineer who joined Cruise in 2020 to lead the perception team and later became Senior Director in charge of Autonomy:

Cruise was founded in 2013 to develop self-driving technology. It was acquired by GM in 2016. It operated its own self-driving fleet independently of GM, but it also contributed to the development of the automaker’s ADAS system.

A series of accidents and failures in 2023 led the company to withdraw its fleet of over 100 self-driving vehicles from the road.

They have tried to bring back their autonomous ride-hailing service in California, but GM announced that it would stop funding the company in December and commenced a restructuring to entirely discontinue autonomous fleet operations and fold some of Cruise into GM’s ADAS operations for consumer vehicles.

Kuang has reportedly exited Cruise in 2024 and now joined Tesla last month, according to an update on his LInkedIn profile.
