extreme heat grid renewables

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.

Segway’s feature-packed E3 Pro electric scooter with Apple Find My hits new $500 Black Friday low (Save $200)

Segway’s Black Friday Sale is in full gear and currently seeing hundreds in savings and plenty of returning and new low prices on its e-scooters and e-bikes. One such standout is Segway’s latest E3 Pro Electric Scooter down at $499.99 shipped, and which seems to have disappeared from Amazon’s marketplace. Carrying a $700 MSRP since launching back at the top of October, we’ve only seen this model given $100 price cuts in its launch deal and the brand’s Halloween and early Black Friday sales. Now, with things having ramped up with increased savings now that Black Friday is in full swing, you can score a larger-than-ever $200 markdown to a new all-time low price, giving you an advanced upgrade to your commute that I have been loving so far since getting one a short time ago.

I’ve been riding around Brooklyn for a short time now with my own Segway E3 Pro Electric Scooter and have been loving my experience so far, as it’s a MAJOR step up from the very basic E22 model I’ve had for short travels since 2020. While power has been significantly ramped up from its E2 Pro predecessor, this new generation still retains a fairly lightweight 40-pound design, which I am able (as a not-so-strong person) to carry easily with one hand/arm up and down my second-story stoop.

Segway’s E3 Pro comes bearing a 400W motor (with 800W peaking) alongside a 368Wh battery, the combination of which delivers up to 34 miles of commuting support for your travels at up to 20 MPH speeds. The regenerative brake paired with the brand’s SegRange Optimization tech really lends towards the extended travel times here, with safety taken into mind with the SegRide stability enhancement tech, the latest traction control system, turn signaling, RGB ambient lighting for nighttime journeys, and a bright headlight. What’s more, security is bolstered by the Apple Find My inclusion for those worried about tracking it down should theft (or forgetfulness) occur.

One thing I have really been enjoying, especially when riding over more pot-hole lined streets, is Segway’s E3 Pro’s dual elastomer suspension, which does a great job of smoothing out overall rides, while providing added cushioning when sudden, jolting sections of the road (or debris/trash) are driven over. Along with all those, there are also additional features, including the previously mentioned rear electronic regen brake getting a companion front drum brake, as well as 10-inch self-sealing jelly tires, an IPX5 water-resistant build, a 265-pound total payload, and a 3-inch full-color LED screen for setting adjustments.

Be sure to check out Segway’s full official Black Friday Sale while it lasts for a short while longer, which can save you hundreds at the best prices of the year starting from $150.

Anker’s SOLIX C300X 90,000mAh portable power station + solar bundle option at new Black Friday lows from $160

As part of Amazon’s ongoing Black Friday Week Sale, and running parallel to Anker’s SOLIX Black Friday Sale, the brand’s official storefront is offering the C300X 90,000mAh Portable Power Station (misnamed on page as C200X) for $159.99 shipped. Normally going for $300 at full price, this alternate darker colorway beats out its standard grey colorway’s direct sale pricing by $40, with its Amazon pricing on that model also beaten out by the same amount. Discounts before October kept things above $189, with increased falls lower to 169 and $161 over last month and mid-way through this month, before this Black Friday deal dropped things to a new all-time low. Not only are you saving a total $140 here, but you’ll also be getting the best price tracked on the station’s 60W foldable solar panel bundle that’s down at a low of $240 shipped.

Tesla has sold ~100 cars since entering the world's largest country in July

tesla store how to test drive buy a tesla

Tesla’s much-awaited entry into the Indian market has resulted in very slow sales to start, but it may not all be bad.

We’ve covered the years-long effort of Tesla to enter the Indian auto market. There have been a lot of intentions and fits and starts, but due to protectionist schemes in the country it never made a lot of sense for Tesla to enter.

That changed this year in March, when India waived EV import duties, allowing foreign firms to bring their cars in for sale. While India does have some strong local brands in Mahindra and Tata, this opened the gates to Chinese, German, Korean and American brands – namely, Tesla.

So far, other American companies have declined to bring their EVs to India, but Tesla opened its first showroom in Mumbai, India’s most populous city and financial capital, in July of this year. It opened a larger “Tesla Center” showroom in Gurugram, outside Delhi, this week.

So, Tesla is only getting started in India, but by all measures it has been an exceedingly slow start, according to the BBC.

Dealership data shows that Tesla has only sold “just over” 100 cars in India since July, an exceedingly low number by any measure – especially when considering the India is now the most populous country in the world, with a population of just under 1.5 billion.

Tesla’s rocky start included losing its head of Indian operations just before launching its first store, among a slew of other executive departures this year and last.

The numbers look a little less bad when comparing against EV sales in the country. While India has sold an impressive 2 million electric vehicles this year, the vast majority of them have been electric scooters.

Electric passenger cars are a much lower share at around 160k total unit sales this year so far, making up only around 3% of the passenger car market. And the majority of those are lower-cost domestic brands Mahindra and Tata or a growing section of Chinese challengers, with very few sales from overseas luxury brands.

Tesla could be included in that “luxury brand” list, largely due to the price of its imported vehicles. While the Model Y starts at $40k in the US, that price rises to 5,989,000 Rupees in India (~$67k USD). This is simply an unaffordable price for the vast majority of Indians – indeed, only around 1% of India’s auto sales are in the “luxury” category.

Further, EV infrastructure is not very well developed in the country. Tesla has one Supercharger in India, and two listed as “coming soon” in the Gurugram area. There are thousands of other charging points across India (and of course, drivers can charge overnight at home), but the number is still relatively low compared to the country’s population.

Meanwhile, other brands’ EV sales are growing well in India. The auto market as a whole has grown by about 13% this year in the developing country, but EV car sales have grown by 57% in the same period, rapidly outpacing the auto industry as a whole.

Much of that sales growth has been driven by Chinese EVs, which make up around a third of the market. That’s around ~60k Chinese EVs sold this year in India.

Even luxury German EVs from Mercedes, BMW and Audi have sold around 4,000 units so far this year, not a large number, but certainly dwarfing Tesla’s.

So while it’s tempting to look at Tesla’s poor numbers and make excuses about the size of the EV market, ability of Indians to afford luxury vehicles, or state of India’s charging network, it’s hard to compare that low ~100 sales number at any of the competition and label it as anything other than an extremely poor showing.

But, you do have to start somewhere, and the company is only a few months in. So we’ll have to see where it goes from here – though with the sales we’ve seen so far in Mumbai, entering the Delhi market is unlikely to forestall Tesla’s current global sales decline.

The 30% federal solar tax credit is ending this year. If you’ve ever considered going solar, now’s the time to act. To make sure you find a trusted, reliable solar installer near you that offers competitive pricing, check out EnergySage, a free service that makes it easy for you to go solar. It has hundreds of pre-vetted solar installers competing for your business, ensuring you get high-quality solutions and save 20-30% compared to going it alone.
