Electrek spoke with Kam Mahdi, CEO of renewable engineering firm Clean Energy Technologies in Costa Mesa, California, about how extreme heat can impact the power grid and renewables, as well as what’s being done to keep them online.
Electrek: The southern US and other parts of the world are currently suffering an extreme heat wave, and it’s expected to continue. How can that kind of heat impact the power grid?
Kam Mahdi: The spike in temperatures inevitably drives up electricity demand, particularly due to the increased use of air conditioning. This additional demand often strains the power grid, sometimes to the point of triggering blackouts or requiring rolling blackouts to stave off a complete grid failure.
Extreme heat can also impair the efficiency of power generation and transmission. Both renewable and conventional power plants may operate less efficiently under high temperatures. Likewise, electricity transmission lines can lose efficiency due to higher resistive losses at elevated temperatures.
Adding to the complexity, these hot and dry conditions also elevate the risk of wildfires, which can wreak havoc on transmission infrastructure. This, in turn, can lead to power outages and exacerbate the challenge of power management across the grid.
Electrek:How can the high temperatures affect solar, wind, and battery storage?
Kam Mahdi: Solar and wind have unique challenges in high temperatures. While sunshine is, of course, needed to generate electricity from solar panels, extreme heat can reduce solar panels’ output efficiency by a margin of 10-25%. That’s because as the solar panel’s temperature rises, the output voltage correspondingly declines, consequently impairing the production of electricity.
Wind energy can also be impacted. Generally, high temperatures can coincide with high-pressure weather systems that lead to calm conditions, reducing wind power generation.
Battery storage systems, particularly lithium-ion batteries, can suffer in high temperatures as well. Excessive heat can accelerate chemical reactions within the battery, leading to faster degradation and reduced lifespan. Additionally, heat can increase the risk of thermal runaway, a condition that can lead to battery failure.
Electrek:Are there innovations that can be utilized to counteract the negative effects of extreme heat on renewables and battery storage?
Kam Mahdi: Engineers worldwide are currently exploring innovative concepts like thermophotovoltaics, which directly convert heat into electricity. They’re also refining solar panel designs, utilizing advanced materials and coatings for enhanced heat resistance.
In the wind energy sector, we are leveraging predictive weather models to manage power generation more effectively during high heat and low wind periods, coupled with the continual improvement of turbine design.
The battery storage industry is now focusing on robust thermal management systems incorporating advanced cooling methods, heat-resistant materials, and improved battery design in order to ensure optimum performance and extended longevity in challenging thermal conditions.
Our company, Clean Energy Technology, is contributing to this collective effort. Our heat recovery solutions enable us to capture and repurpose waste heat – a byproduct of industrial processes and power generation. This process increases efficiency and proves instrumental in managing energy demand, particularly during intense heat periods when power consumption peaks.
It’s important to incorporate a healthy mix of renewables alongside energy storage systems, which can help create a more resilient grid that’s capable of withstanding the strains brought about by extreme heat.
These strategies, combined with energy conservation efforts, are vital in ensuring a reliable energy supply, even in severe heat waves.
Kam Mahdi is a cofounder of Clean Energy Technologies (CETY) who has served as chief executive officer since the company’s inception in September 2015. He spearheaded the acquisition of General Electric Heat Recovery Solutions, positioning CETY as a key competitor in the renewable and energy efficiency sectors. Mahdi holds a bachelor of science in electrical engineering from California State University, Northridge.

Robyn Denholm, Tesla’s chairwoman, made five times more money than the next best-paid board chair, a role Tesla’s CEO Elon Musk said was useless.
In 2018, Musk settled with the SEC for falsely claiming he had secured funding to take Tesla private at $420 a share, he was forced to resign as chair of Tesla’s board.
Musk basically handpicked Robyn Denholm to become the new chair, which he then called a useless “honorific” titled:
“Chairman’ is an honorific, not executive role, which means it’s not needed to run Tesla. Will retire that title at Tesla in 3 years.”
Denholm made a lot of money in this useless honorific role.

She has made over $530 million, almost entirely through stock option compensation, since becoming Tesla’s chairperson.
Most of her stock sales happened over the last year:
The New York Times released a new report looking into Denholm’s compensation and found that she was paid about 5 times more than the next best-paid nonexecutive chair.
Tesla paid its chair about 5 times more than UnitedHealth’s:
The nonexecutive chair with the next-highest profit from selling shares in the company he oversees was Stephen Hemsley of UnitedHealth Group. Mr. Hemsley has earned more than $100 million from the sale of UnitedHealth shares since November 2018, though he received all of that stock while he was chief executive of the health care company.
To Musk’s point about the role being honorific, it’s not clear what Denholm accomplished during her time as chair.
She and the rest of Tesla’s board oversee Tesla’s executive management, led by Musk, but Musk has been allowed to do whatever he wants for years.
Most recently, they have not addressed the protests at Tesla stores and product boycotts, which are attributed to Musk’s involvement in politics, angering a significant portion of the population and Tesla’s consumer base.
Only recently was there a report suggesting the board floated the idea of replacing Musk to gain leverage in forcing him to spend more time at Tesla. Even then, the board quickly denied the report, which only claimed that they were doing their jobs in planning the CEO succession.
Electrek’s Take
Based on Musk’s comment, Denholm was paid half a billion dollars to do nothing. That’s literally all that was required of her after replacing Musk as chair of the board: nothing.
Musk is in charge. She is just an “honorific” figurehead that is required to back his every move.
Just as Tesla’s then-third-largest individual shareholder, after Musk, Leo KoGuan, told Electrek last year, when he couldn’t get his concerns about Musk heard by the board, Tesla is “a family business masquerading as a public company.”

Less than a year after announcing an order for 27 electric seaglider planes from REGENT Craft, advanced air mobility (AAM) specialist UrbanLink has nearly doubled that order size to support plans for high-frequency commercial flights around the southeastern United States.
While advanced air mobility may be a nascent industry, companies around the globe are continuously gearing up to establish commercial networks that support air taxi travel and other sustainable commercial operations. In the US, particularly Southern Florida, UrbanLink has been making tons of moves to establish itself as a major player in that space when it happens.
UrbanLink has already been working for years to enable zero-emission, end-to-end travel within a 500-mile range by 2028 before expanding that range to 1,000 miles by 2030, beginning with its hub cities of Miami, Los Angeles, and San Juan, Puerto Rico.
The company believes its actions have adequately positioned it to become the first airline in the US to integrate electric vertical takeoff and landing (eVTOL) aircraft into its fleet. Fellow eVTOL network Archer Aviation is also in the race, so it’s exciting times for commercial air taxi development.

UrbanLink has committed to purchasing from several eVTOL and electric plane developers, including Artemis Sea Crafts, Eviation Aircraft, and Lilium, as we reported back in June 2024. Last fall, the AAM operator announced it was adding more vessels to its growing fleet in South Florida, committing to purchase 27 electric seagliders from REGENT Craft.
Today, UrbanLink and REGENT announced an expansion of their existing partnership in which the former has upped its purchase order to 47 electric seagliders.

UrbanLink ups seaglider order to support FL, Puerto Rico
REGENT Craft and UrbanLink shared details of the expanded partnership this morning, in hopes of establishing Florida as the bona fide leader in sustainable coastal aerial mobility.
Per the company, the nearly doubling of the existing order for REGENT’s Viceroy electric seagliders will support a more rapid rollout of UrbanLink’s aerial operations between the southern Florida and Puerto Rico regions. REGENT co-founder and CEO Billy Thalheimer spoke about the expanded seaglider order:
UrbanLink’s expanded order is a clear vote of confidence in REGENT’s seaglider technology and is testament to our continued timely execution certification and product development milestones. Together, we’re building a more convenient and connected future for coastal communities.
As the map above shows, electric sea glider travel can cut the travel time from Miami to West Palm Beach by nearly 75%. This single route represents a growing demand for convenient and more sustainable alternatives for short-haul travel in the US, and UrbanLink hopes to provide that to Florida visitors and beyond.
For example, the company shared that it anticipates that its seaglider operations in Miami alone could provide more sustainable travel options to up to 4.3 million passengers per year when commercial operations begin. UrbanLink founder and chairman Ed Wegel also spoke:
We’re proud to expand our partnership with REGENT and bring this revolutionary technology to more passengers traveling high-demand routes across Florida and Puerto Rico. This partnership propels Florida to the forefront of global innovation in advanced, all-electric mobility.
REGENT’s full-scale Viceroy electric seaglider prototype is currently in the process of successful sea trials en route to certification from the US Coast Guard. These 12-passenger vessels can reach up to 180 mph and travel up to 180 miles on a single charge.
First deliveries of the Viceroy seagliders to UrbanLink are expected to begin sometime in 2027.

It’s official. Toyota is finally launching a new EV in the US. The C-HR will return in what’s expected to be an affordable electric SUV. Here’s our first look at the 2026 Toyota C-HR, a surprisingly stylish EV with nearly 300 miles of range.
Meet the 2026 Toyota C-HR electric SUV for the US
Who could forget the original Toyota C-HR? The funky-looking compact SUV was priced under $25,000 but was discontinued in 2022 to make way for the more efficient Corolla Cross hybrid.
The C-HR will make a comeback in the US as a fully electric SUV with nearly 300 miles of range. After revealing the electric SUV in Europe earlier this year, Toyota confirmed on Wednesday that the C-HR will, in fact, arrive in the US.
Outside of a “+” added at the end of the name (C-HR+), the US and European versions look nearly identical. The electric version is a drastic upgrade over the retired gas-powered model.
