United Rentals is now the first major rental company to offer mobile micro grid battery power to its North American fleet of rental equipment. The HiPower EHR Solar Battery Generator boasts a 5.0kW peak solar array with extendable panels, converting and storing energy within built-in batteries.
The EHR Solar Battery Generator is versatile, fitting on a 20-by-8-ft trailer or a skid (as shown, below) with a charging station for electric tools, vehicles, and equipment. Beyond that, it can act as a primary power source for transient spaces such as mobile trailers or container offices.
“The EHR Solar Battery Generator is a game-changer for companies that want to go to the next level of sustainability with higher energy efficiency to reduce jobsite emissions and fuel use,” explains Larry Worthington, vice president, PHVAC region at United Rentals. “The system can reduce emissions and noise levels to zero, making it an ideal fit for various applications, including urban, noise-sensitive environments.”
For their part, the people at Hipower seem equally excited about the collaboration. “As part of its commitment to providing a more electric equipment rental fleet, United Rentals is leading the way in offering on-site, sustainable charging stations to ensure customers can easily and efficiently recharge electric equipment,” said Rafael Acosta, president at Hipower, in a statement. “(United Rentals) were an instrumental partner in helping us develop the EHR Solar Battery Generator, a cutting-edge microgrid system that has the potential to revolutionize power generation and energy management.”
Hipower says its EHR generators offer a high performance in a wide range of temperatures from 5ºF to 113ºF, is available in both single-phase (-10, 20 & 40 kVA) and three-phase (15 & 30 kVA) nominal power solutions, with two different storage capacity options per model (ratios of 1:1 and 1:2) and an overload capacity of up to 300% to start electrical motors.
Electrek’s Take
Determining which equipment assets to purchase and which to rent is a key aspect of any fleet manager’s role. The shift toward decarbonization and electrification introduces new considerations, especially when it comes to supplying electricity to job sites without grid connections. Many fleets face challenges in solving this equation. That’s why having immediate access to potential charging solutions like the HiPower EHR Solar Battery Generator becomes crucial.
“A lot of this electric stuff is new to us,” Mike Switzer, Equipment Manager at Stevens Engineers & Constructors, told me. “So if we can rent a solution and try it out and make sure it does what the manufacturer or dealer says it can do for us that’s going to go a long way towards helping us understand if this is something we need to buy. Sometimes it’s not, and it just makes sense to rent it as we need it. This is great for that, too.”

Audi has unveiled the Audi ConceptC, an all-electric two-seat roadster that aims to redefine the brand’s design language, and which could also preview an upcoming electric TT sports car successor.
Radical Simplicity in Motion
Unveiled in Milan on 2 September 2025, this concept signals Audi’s shift into sleek, minimalist clarity.
From every angle, the Concept C embodies what Audi now calls “radical simplicity”, a philosophy built around geometric purity, emotional precision, and technical clarity, according to the release.
Central to the car’s identity is the vertical frame, Audi’s reimagining of its signature grille, inspired by the legendary Auto Union Type C (1936) and even the third-gen A6 from 2004.

Its twin-panel, electrically actuated hardtop rocks both coupe-like elegance and open-air allure.

Inside: Clarity Meets Tactility
Inside, the Concept C embraces minimalism without sacrificing substance. Anodized‑aluminum haptic controls, including that satisfying “Audi click,” and a foldable 10.4‑inch center display, offer sleek digital interaction, but nothing feels superfluous.
Audi is calling this “shy tech”—technology that’s always present, never overpowering. Smart, emotional, and intuitive.

Clear Design Vision leaks into Corporate Clarity
This concept is apparently not just a car, it’s a sort of manifesto. CEO Gernot Döllner says that clarity now guides everything at Audi, from design to structure to corporate ethos. The Milan reveal under the banner “Strive for clarity” sets the tone for a bold, focused reimagining of the brand – making this reveal more than about just a new concept.
It’s a full‑scale reorientation, described internally as “The Radical Next” by CCO Massimo Frascella, who emphasizes design as a cultural force, not just a styling exercise.
The Concept C also makes its public debut at IAA Mobility 2025 in Munich, showcased under Audi’s immersive “Feel Audi” experience.
A TT Comeback as an Electric Vehicle?
Now, Autocar released a report adding a lot of context around the concept unveil: Audi is reportedly working on an electric TT‑inspired drop‑top, targeting 2027, and this concept could be fairly close to what the German automaker could bring to production.
It would be positioned as a retro‑styled EV, the car would slot in as a Boxster‑rival, potentially sharing its bones with a Porsche counterpart, which is also going electric.
Audi already retired the TT and the R8—leaving a gap in its two‑door sports car lineage. But according to CEO Döllner, sports cars are still part of Audi’s DNA, and their return is not off the table—especially when the timing is right.
Design chief Frascella has a long‑standing personal connection to the TT—it inspired him as a young designer, and he’s excited about bringing that emotional spark into a new EV concept. But, he cautions, it won’t be derivative. Expect something that captures the essence without cloning the past.
A future electric TT would be Audi Sport’s “emotional compact”, built on the surging wave of electrification, and maybe, just maybe, born from the same radical simplicity that powers the Concept C.
Electrek’s Take
As you know, it’s hard for us at Electrek to get excited about new concept cars, but it does sound like Audi isn’t just sketching a pretty concept here.
The vehicle appears to signal a new design language for the four-ring brand and could even preview a new electric sports car.
If it’s indeed the direction Audi is heading, I like it. It manages to be both retro and futuristic without doing too much. That’s impressive.
I appreciate the minimalism all around, but especially in the interior, where, even though it’s just a concept, it already feels exceptionally refined.
You definetly should make this Audi.

The ES90 can drive further and charge faster than any of Volvo’s electric cars to date. Its sleek design looks like a fastback, but offers the space of an SUV. After the first ES90 rolled off the assembly line on Thursday, Volvo said its new flagship EV stands in a class of its own.
The first Volvo ES90 EV rolls off the production line
Volvo created quite a stir after unveiling the ES90 in March, its new flagship EV. Although it may look like a sedan, it offers the versatility of an SUV with a spacious interior and higher ground clearance.
It’s also the first Volvo model based on its new 800V SPA2 architecture. The advanced new platform unlocks some of the world’s fastest charging speeds, along with an impressive driving range.
Based on the new platform, the ES90 can gain up to 300 km (186 miles) of range in just 10 minutes using a 350 kW fast charger. It also provides a driving range of up to 700 km (435 miles), making it the “most technically advanced” Volvo EV to date.

Volvo’s new Superset tech stack enables the ES90 to improve and “evolve” through software updates. All of that, and it’s still designed with Volvo’s advanced safety tech at its core.
The ES90 “is set to be another Scandinavian design classic from Volvo Cars,” the company boasted. Volvo has already opened ES90 orders in several European markets and will soon launch it in the Asia Pacific region. In Germany, the ES90 starts at €71,990 ($84,000) with higher trim options priced upwards of around €95,000 ($110,000).

The Danish renewable energy company Orsted sued the Trump administration on Thursday to prevent it from blocking the completion of a wind farm off the coast of New England.
The Interior Department abruptly ordered Orsted on August 22 to halt construction on Revolution Wind off the coast of Rhode Island and Connecticut. The fully permitted project is 80% complete and would provide enough power for more than 350,000 homes across both states.
Orsted asked the United States District Court for the District of Columbia to set aside the stop-work order, calling it “unlawful” and “issued in bad faith.”
The Bureau of Ocean Energy Management has justified the order on national security grounds and concerns that Revolution Wind will interfere with other uses of U.S. territorial waters. But Orsted said this justification is just a pretext, pointing to President Donald Trump’s long-standing animus toward wind power going back more than a decade.
“The President has apparent hostility towards offshore wind, including based on statements made on the campaign trail,” Orsted’s attorney told the court.
Revolution Wind has undergone extensive environmental and safety reviews over nearly a decade that cost hundreds of millions of dollars, according to Orsted’s lawsuit. Federal agencies have uniformily concluded based on thousands of pages of data that the project is “environmentally sound, safe and consistent with federal law,” the company said.
Trump has targeted the wind industry since his first day in office, when he issued an order that closed federal waters to new leases for offshore projects. But the renewable industry had hoped that the White House would allow permitted projects such as Revolution Wind to proceed.
Trump has escalated his attacks on the renewable energy industry in recent weeks. The president said his administration would not approve solar and wind projects two days before Revolution Wind was hit with the stop-work order.
And the Trump administration on Friday cancelled $679 million in funding for a dozen infrastructure projects that support the offshore wind industry.
