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.”

In a bold bid to combat the crippling air pollution crisis in its capital, Delhi, Indian lawmakers have begun high-level discussions about a plan to phase out gas and diesel combustion vehicles by 2035 – a move that could cause a seismic shift in the global EV space and provide a cleaner, greener future for India’s capital.
Long considered one of the world’s most polluted capital cities, Indian capital Delhi is taking drastic steps to cut back pollution with a gas and diesel engine ban coming soon – but they want results faster than that. As such, Delhi is starting with a city-wide ban on refueling vehicles more than 15 years old, and it went into effect earlier this week. (!)
“We are installing gadgets at petrol pumps which will identify vehicles older than 15 years, and no fuel will be provided to them,” said Delhi Environment Minister Manjinder Singh Sirsa … but they’re not stopping there. “Additionally, we will intensify scrutiny of heavy vehicles entering Delhi to ensure they meet prescribed environmental standards before being allowed entry.”
The Economic Times is reporting that discussions are underway to pass laws requiring that all future bus purchases will be required to be electric or “clean fuel” (read: CNG or hydrogen) by the end of this year, with a gas/diesel ban on “three-wheelers and light goods vehicles,” (commercial tuk-tuks and delivery mopeds) potentially coming 2026 to 2027 and a similar ban privately owned and operated cars and bikes coming “between 2030 and 2035.”
Electrek’s Take

Last week, Parker Hannifin launched what they’re calling the industry’s first certified Mobile Electrification Technology Center to train mobile equipment technicians make the transition from conventional diesel engines to modern electric motors.
The electrification of mobile equipment is opening new doors for construction and engineering companies working in indoor, environmentally sensitive, or noise-regulated urban environments – but it also poses a new set of challenges that, while they mirror some of the challenges internal combustion faced a century ago, aren’t yet fully solved. These go beyond just getting energy to the equipment assets’ batteries, and include the integration of hydraulic implements, electronic controls, and the myriad of upfit accessories that have been developed over the last five decades to operate on 12V power.
At the same time, manufacturers and dealers have to ensure the safety of their technicians, which includes providing comprehensive training on the intricacies of high-voltage electric vehicle repair and maintenance – and that’s where Parker’s new mobile equipment training program comes in, helping to accelerate the shift to EVs.
“We are excited to partner with these outstanding distributors at a higher level. Their commitment to designing innovative mobile electrification systems aligns perfectly with our vision to empower machine manufacturers in reducing their environmental footprint while enhancing operational efficiency,” explains Mark Schoessler, VP of sales for Parker’s Motion Systems Group. “Their expertise in designing mobile electrification systems and their capability to deliver integrated solutions will help to maximize the impact of Parker’s expanding METC network.”

The manufacturing equipment experts at Nott Company were among the first to go through the Parker Hannifin training program, certifying their technicians on Parker’s electric motors, drives, coolers, controllers and control systems.
“We are proud to be recognized for our unwavering dedication to advancing mobile electrification technologies and delivering cutting-edge solutions,” says Nott CEO, Markus Rauchhaus. “This milestone would not have been possible without our incredible partners, customers and the team at Nott Company.”
In addition to Nott, two other North American distributors (Depatie Fluid Power in Portage, Michigan, and Hydradyne in Fort Worth, Texas) have completed the Parker certification.
Electrek’s Take

With the rise of electric equipment assets like Bobcat’s T7X compact track loader and E10e electric excavator that eliminate traditional hydraulics and rely on high-voltage battery systems, specialized electrical systems training is becoming increasingly important. Seasoned, steady hands with decades of diesel and hydraulic systems experience are obsolete, and they’ll need to learn new skills to stay relevant.
Certification programs like Parker’s are working to bridge that skills gap, equipping technicians with the skills to maximize performance while mitigating risks associated with high-voltage systems. Here’s hoping more of these start popping up sooner than later.
Based on a Peterbilt 579 commercial semi truck, the ReVolt EREV hybrid electric semi truck promises 40% better fuel economy and more than twice the torque of a conventional, diesel-powered semi. The concept has promise – and now, it has customers.
Austin, Texas-based ReVolt Motors scored its first win with specialist carrier Page Trucking, who’s rolling the dice on five of the Peterbilt 579-based hybrid big rigs — with another order for 15 more of the modified Petes waiting in the wings if the initial five work out.
The deal will see ReVolt’s “dual-power system” put to the test in real-world conditions, pairing its e-axles’ battery-electric torque with up to 1,200 miles of diesel-extended range.

The ReVolt team starts off with a Peterbilt, then removes the transmission and drive axle, replacing them with a large genhead and batteries. As the big Pete’s diesel engine runs (that’s right, kids – the engine stays in place), it creates electrical energy that’s stored in the trucks’ batteries. Those electrons then flow to the truck’s 670 hp e-axles, putting down a massive, 3500 lb-ft of Earth-moving torque to the ground at 0 rpm.

The result is an electrically-driven semi truck that works like a big BMW i3 or other EREV, and packs enough battery capacity to operate as a ZEV (sorry, ZET) in ports and urban clean zones. And, more importantly, allows over-the-road drivers to hotel for up to 34 hours without idling the engine or requiring a grid connection.
That ability to “hotel” in the cab is incredibly important, especially as the national shortage of semi truck parking continues to worsen and the number of goods shipped across America’s roads continues to increase.
And, because the ReVolt trucks can hotel without the noise and emissions of diesel or the loss of range of pure electric, they can immediately “plug in” to existing long-haul routes without the need to wait for a commercial truck charging infrastructure to materialize.
“Drivers should not have to choose between losing their longtime routes because of changing regulatory environments or losing the truck in which they have already made significant investments,” explains Gus Gardner, ReVolt founder and CEO. “American truckers want their trucks to reflect their identity, and our retrofit technology allows them to continue driving the trucks they love while still making a living.”
If all of that sounds familiar, it’s probably because you’ve heard of Hyliion.
In addition to being located in the same town and employing the same idea in the same Peterbilt 579 tractor, ReVolt even employs some of the same key players as Hyliion: both the company’s CTO, Chandra Patil, and its Director of Engineering, Blake Witchie, previously worked at Hyliion’s truck works.
Still, Hyliion made their choice when they shut down their truck business. ReVolt seems to have picked up the ball – and their first customer is eager to run with it.
“Our industry is undergoing a major transition, and fleet owners need practical solutions that make financial sense while reducing our environmental impact,” said Dan Titus, CEO of Page Trucking. “ReVolt’s hybrid drivetrain lowers our fuel costs, providing our drivers with a powerful and efficient truck, all without the need for expensive charging infrastructure or worrying about state compliance mandates. The reduced emissions also enable our customers to reduce their Scope 2 emissions.”
Page Trucking has a fleet of approximately 500 trucks in service, serving the agriculture, hazardous materials, and bulk commodities industries throughout Texas. And, if ReVolt’s EREV semis live up to their promise, expect them to operate a lot more than 20 of ’em.
