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.

Another Japanese automaker is now 're-evaluating' EV plans

Subaru is the latest Japanese automaker to announce it will “re-evaluate” its EV plans. The company is rethinking its strategy with slowing sales and a potential multi-billion-dollar hit from Trump’s auto tariffs. The tariffs might not even be Subaru’s biggest threat.

Subaru and other Japanese automakers adjust EV plans

Within the past week, Japanese automakers, including Nissan, Honda, Toyota, and now Subaru, have announced major adjustments to their EV plans.

After releasing fiscal year financial results on Wednesday, Subaru’s CEO, Atsushi Osaki, said, “We are re-evaluating our plans, including the timing of investments.” Osaki added that the move is due to “today’s rapidly changing environment” and other external factors.

Like most of the industry, Subaru is bracing for a shift under the Trump administration, which could cost it billions. With around half of its vehicles sold, the US is key for the Japanese automaker.

Subaru said Trump’s new auto tariffs could cost the company up to $2.5 billion this year. The automaker is looking at ways to boost US production, but it won’t be easy.

Tomoaki Emori, Subaru’s senior managing executive director, said (via Automotive News), “Under the current circumstances, there is probably no way not to expand in the US. We must think about how to go about that.”

Emori added that the company still has the production capacity, “so we would like to mitigate the impact of tariffs while making use of it.”

Subaru joins a growing list of automakers in pulling its earnings forecast, citing “developments in US tariff policy” make it hard to forecast.

The company’s global sales fell 4.1% to 936,000 units over the past year. In North America, deliveries also fell 4.1% to 732,000 vehicles. Subaru anticipates global sales will continue dropping to around 900,000 this year, or another 4% drop. A part of the forecast is due to downtime at its Yajima plant as Subaru prepares to produce EV batteries.

Osaki said Subaru is “making various preparations for a BEV-dedicated plant,” but added it may add a mix of gas-powered vehicles.

Subaru unveiled its second EV for the US at last month’s NY Auto Show, the 2026 Trailseeker. The Outback-sized electric SUV will go on sale in 2026, joining the smaller Solterra in Subaru’s EV lineup in the US.

Since “It is becoming more difficult to decide how to incorporate electrification into our production mix,” Emori said, Subaru is “thinking about how to incorporate hybrids and plug-in hybrids.”

Electrek’s Take

Subaru and other Japanese automakers are quickly falling behind Chinese EV leaders like BYD in some of their most important sales regions, like Southeast Asia.

Delaying new EV models and other projects will only set them further behind in the long run. Nissan is in crisis mode after scrapping plans to build a new battery plant in Japan. The facility was expected to produce lower-cost LFP batteries, which could have helped Nissan compete on costs with BYD and others.

Last week, Toyota’s President, Koji Sato, said the company will be “reviewing” its goal of selling 1.5 million electric vehicles by 2026. And just yesterday, Honda announced plans to pause around $15 billion in planned EV investments in Canada.

BYD and other EV leaders are expanding overseas to drive growth after squeezing foreign brands, especially Japanese automakers, out of China.

Next year, BYD is launching its first kei car, or mini EV, that’s expected to be a big threat to Japanese automakers. A Suzuki dealer (via Nikkei) warned, “Young people do not have a negative view of BYD. It would be a huge threat if the company launches cheap models in Japan.”

Tesla (TSLA) board explore new pay deal for Elon Musk

Tesla’s (TSLA) board is reportedly exploring a new CEO pay deal for Elon Musk, who might not get back his $55 billion 2018 compensation package.

According to a new Financial Times report, Tesla’s board created a new “special committee” to explore a new CEO pay package for Musk.

The report points to the committee looking at new stock options and “alternative ways” to compensate Musk if Tesla fails to reinstate his 2018 compensation package, which was rescinded by a judge who found that Musk negotiated the deal with a board under his control and then misrepresented it to shareholders.

Musk is Tesla’s largest shareholder and therefore, he stands to benefit the most when the company does well. However, he doesn’t take a salary for his role as CEO.

Historically, He has received stock compensation packages, with the one secured in 2018 being the controversial one currently under contention.

Since then, no new CEO compensation package has been approved, and Tesla has not suggested another one as it tried to appeal the judge’s decision on the 2018 package.

The company is currently attacking the decision on two fronts with an appeal to the Delaware Supreme Court and a new legislation in Delaware to try to circumvent the decision altogether.

FT reporting that the board is working on a new compensation package with backpay could point to Tesla anticipating not being able to reinstate the original compensation package.

Robyn Denholm and Kathleen Wilson-Thompson are the board members reportedly on the new committee.

Denholm took over from Musk as Tesla’s chair, and she has recently made headlines for selling her Tesla stock options for more than $530 million over the last few years.

Electrek’s Take

It increasingly looks like Tesla won’t be able to distance itself from Musk and separate its fate from his.

Musk has masterfully convinced Tesla shareholders that the destruction of its core business, selling electric vehicles, doesn’t matter because the company is on the verge of solving self-driving – something he has claimed every year for the last 6 years and has been wrong every time.

Now that they don’t care about EVs, there’s no point in blaming Musk for killing demand and delivering a single new vehicle in 5 years, the Cybertruck, a commercial flop.

Therefore, the only thing that will make Tesla shareholders stop wanting Musk as CEO is if they stop believing his self-driving and humanoid robot claims.
