In the face of a devastating heat wave, the rickety system has managed to keep ACs around the state running. How?
Texas’ uniquely isolated and deregulated electricity grid has been wobbling on the edge of rolling blackouts this week thanks to extreme heat throughout the state.
At least so far, the grid has survived, despite less wind than expected, some power plants going offline, and near-record levels of demand. It hasn’t been so lucky in the past. The state became a poster child for the risk that extreme weather can pose to electricity generation in 2021 when Winter Storm Uri led to massive and deadly blackouts.
With Texas still facing a potentially deadly combination of extreme weather, homes that rely on electricity for both heating and cooling, and an energy market that has historically underinvested and underemphasized resiliency and is disconnected from the rest of the country, how has the state managed to avoid devastating blackouts during this heat wave — and I can’t stress this enough — so far?
One big reason is that electricity generation hasn’t quite hit the record-breaking levels ERCOT, the grid operator, has feared.
On Tuesday, power peaked at just over 79,000 megawatts, just below the over 80,000 megawatts record demand last summer, despite temperatures at or near 100 degrees — and heat indices approaching an astonishing 120. ERCOT had forecasted a record-setting electricity consumption day, but actual electricity demand fell below its predictions for the late morning and the afternoon.
Highlighting the risk still confronting the state, ERCOT has forecast that demand for power Wednesday will break records though.
“It has been record or near-record heat in South Texas, not so much in North Texas. Even though the ERCOT electric grid is relatively small, it’s been big enough to move power around from where it’s needed less to needed more,” Texas A&M professor and state climatologist John Nielsen-Gammon told me in an email Tuesday afternoon. One big concern with Texas’ grid is that when the entire state is in need of power, it can’t import electricity from the rest of the country, but at least so far, intra-state transfers have been sufficient.
That could be because ERCOT did itself — and Texas — a massive favor by sending out a warning to Texans on Tuesday just asking them “to voluntarily reduce electric use, if safe to do so.”
These kind of informal requests to reduce power consumption at moments of high demand are not uncommon and can work — they’ve been used successfully in New York and California. They’ve even been used before in Texas during the summer, despite the state’s reputation for being more generation-than-conservation friendly compared to its big state peers.
When comparing the disaster in 2021 to today, it’s also helpful to note that a big reason the state struggled back then was large amounts of natural gas generation going offline due to poor winterization.
Summertime brings even higher electricity demand than the winter, but it tends not to pose the same threat to the grid, explained University of Texas researcher Joshua Rhodes.
“The vulnerability in the summer is that everyone has an air conditioner,” Rhodes said.
That same high heat that causes people to crank up their air conditioning also means that solar power tends to be more abundant at the same time. By the late afternoon Tuesday, solar was providing 14.5% of Texas’ electricity, operating at 90 percent of its summer capacity. Meanwhile natural gas was responsible for just over half of Texas’ electricity generation, but operating at 85 percent of its summer capacity.
“Whoever designed it such that solar energy output is high when it is hot outside was brilliant,” University of Texas professor of energy resources Michael Webber tweeted Tuesday afternoon.
Natural gas power plants can underperform due to high heat, Rhodes said, but the risk of catastrophic failure is lower. Texas also schedules power plant maintenance in order to ensure that plants are online during the highest demand portion of the year.
But while natural gas provides the bulk of Texas’ electricity, wind and solar play a substantial and growing role in the state’s power generation. When ERCOT requested that Texans voluntarily reduce power consumption, it cited “higher than normal” power plant outages as well as “low wind generation compared to historic performance during summer peak.”
Like much of the country, fossil-fuel-rich Texas is dependent on renewables to keep the lights (and AC) on. The head of the Public Utility Commission of Texas warned in May that “On the hottest days of summer, there is no longer enough on-demand dispatchable power generation to meet demand on the ERCOT system.”
According to ERCOT figures from Tuesday, the listed summer capacity of coal, nuclear, and natural gas would have fallen short of peak demand, let alone the record demand forecasted on Monday, so solar really has played an important role in keeping danger at bay — and, again, I can’t stress this enough — so far.
As might be expected in a conservative state with a massive energy industry, when it came time to address reliability issues following Uri and record breaking heat last summer, Texas’ elected officials chose to do so in a way that would favor more fossil generation, as opposed to energy efficiency or more extensive demand management. Governor Greg Abbott signed a slew of bills in its past legislative session, including a bill that would set up a program for billions of dollars worth of loans for new gas-fueled power plants, while vetoing a bill that would allow the state to update building codes due to a fight between the governor's mansion and the statehouse over property taxes.
But Texas remains a renewable powerhouse, and like renewable-heavy California with its “duck curve,” Texas faces its own late-day energy crunch, in its case a so-called “armadillo curve,” when solar power drops out of the grid even as demand remains high thanks to continued high temperatures.
At least so far this week, the grid has held up. But summer has only just begun. The National Weather Service projects that “Excessive Heat Warnings may return” in parts of Texas this weekend and early next week. And ERCOT plans every year around power demand peaking in August.

What he wants them to do is one thing. What they’ll actually do is far less certain.
Donald Trump believes that tariffs have almost magical power to bring prosperity; as he said last month, “To me, the world’s most beautiful word in the dictionary is tariffs. It’s my favorite word.” In case anyone doubted his sincerity, before Thanksgiving he announced his intention to impose 25% tariffs on everything coming from Canada and Mexico, and an additional 10% tariff on all Chinese goods.
This is just the beginning. If the trade war he launched in his first term was haphazard and accomplished very little except costing Americans money, in his second term he plans to go much further. And the effects of these on clean energy and climate change will be anything but straightforward.
The theory behind tariffs is that by raising the price of an imported good, they give a stronger footing in the market; eventually, the domestic producer may no longer need the tariff to be competitive. Imposing a tariff means we’ve decided that a particular industry is important enough that it needs this kind of support — or as some might call it, protection — even if it means higher prices for a while.
The problem with across-the-board tariffs of the kind Trump proposes is that they create higher prices even for goods that are not being produced domestically and probably never will be. If tariffs raise the price of a six-pack of tube socks at Target from $9.99 to $14.99, it won’t mean we’ll start making tube socks in America again. It just means you’ll pay more. The same is often true for domestic industries that use foreign parts in their manufacturing: If no one is producing those parts domestically, their costs will unavoidably rise.
The U.S. imported over $3 trillion worth of goods in 2023, and $426 billion from China alone, so Trump’s proposed tariffs would represent hundreds of billions of dollars of increased costs. That’s before we account for the inevitable retaliatory tariffs, which is what we saw in Trump’s first term: He imposed tariffs on China, which responded by choking off its imports of American agricultural goods. In the end, the revenue collected from Trump’s tariffs went almost entirely to bailing out farmers whose export income disappeared.
The past almost-four years under Joe Biden have seen a series of back-and-forth moves in which new tariffs were announced, other tariffs were increased, exemptions were removed and reinstated. For instance, this May Biden increased the tariff on Chinese electric vehicles to over 100% while adding tariffs on certain EV batteries. But some of the provisions didn’t take effect right away, and only certain products were affected, so the net economic impact was minimal. And there’s been nothing like an across-the-board tariff.
It’s reasonable to criticize Biden’s tariff policies related to climate. But his administration was trying to navigate a dilemma, serving two goals at once: reducing emissions and promoting the development of domestic clean energy technology. Those goals are not always in alignment, at least in the short run, which we can see in the conflict within the solar industry. Companies that sell and install solar equipment benefit from cheap Chinese imports and therefore oppose tariffs, while domestic manufacturers want the tariffs to continue so they can be more competitive. The administration has attempted to accommodate both interests with a combination of subsidies to manufacturers and tariffs on certain kinds of imports — with exemptions peppered here and there. It’s been a difficult balancing act.
Then there are electric vehicles. The world’s largest EV manufacturer is Chinese company BYD, but if you haven’t seen any of their cars on the road, it’s because existing tariffs make it virtually impossible to import Chinese EVs to the United States. That will continue to be the case under Trump, and it would have been the case if Kamala Harris had been elected.
On one hand, it’s important for America to have the strongest possible green industries to insulate us from future supply shocks and create as many jobs-of-the-future as possible. On the other hand, that isn’t necessarily the fastest route to emissions reductions. In a world where we’ve eliminated all tariffs on EVs, the U.S. market would be flooded with inexpensive, high-quality Chinese EVs. That would dramatically accelerate adoption, which would be good for the climate.
But that would also deal a crushing blow to the American car industry, which is why neither party will allow it. What may happen, though, is that Chinese car companies may build factories in Mexico, or even here in the U.S., just as many European and Japanese companies have, so that their cars wouldn’t be subject to tariffs. That will take time.
Of course, whatever happens will depend on Trump following through with his tariff promise. We’ve seen before how he declares victory even when he only does part of what he promised, which could happen here. Once he begins implementing his tariffs, his administration will be immediately besieged by a thousand industries demanding exemptions, carve-outs, and delays in the tariffs that affect them. Many will have powerful advocates — members of Congress, big donors, and large groups of constituents — behind them. It’s easy to imagine how “across-the-board” tariffs could, in practice, turn into Swiss cheese.
There’s no way to know yet which parts of the energy transition will be in the cheese, and which parts will be in the holes. The manufacturers can say that helping them will stick it to China; the installers may not get as friendly an audience with Trump and his team. And the EV tariffs certainly aren’t going anywhere.
There’s a great deal of uncertainty, but one thing is clear: This is a fight that will continue for the entirety of Trump’s term, and beyond.
Give the people what they want — big, family-friendly EVs.
The star of this year’s Los Angeles Auto Show was the Hyundai Ioniq 9, a rounded-off colossus of an EV that puts Hyundai’s signature EV styling on a three-row SUV cavernous enough to carry seven.
I was reminded of two years ago, when Hyundai stole the L.A. show with a different EV: The reveal of Ioniq 6, its “streamliner” aerodynamic sedan that looked like nothing else on the market. By comparison, Ioniq 9 is a little more banal. It’s a crucial vehicle that will occupy the large end of Hyundai's excellent and growing lineup of electric cars, and one that may sell in impressive numbers to large families that want to go electric. Even with all the sleek touches, though, it’s not quite interesting. But it is big, and at this moment in electric vehicles, big is what’s in.
The L.A. show is one the major events on the yearly circuit of car shows, where the car companies traditionally reveal new models for the media and show off their whole lineups of vehicles for the public. Given that California is the EV capital of America, carmakers like to talk up their electric models here.
Hyundai’s brand partner, Kia, debuted a GT performance version of its EV9, adding more horsepower and flashy racing touches to a giant family SUV. Jeep reminded everyone of its upcoming forays into full-size and premium electric SUVs in the form of the Recon and the Wagoneer S. VW trumpeted the ID.Buzz, the long-promised electrified take on the classic VW Microbus that has finally gone on sale in America. The VW is the quirkiest of the lot, but it’s a design we’ve known about since 2017, when the concept version was revealed.
Boring isn’t the worst thing in the world. It can be a sign of a maturing industry. At auto shows of old, long before this current EV revolution, car companies would bring exotic, sci-fi concept cars to dial up the intrigue compared to the bread-and-butter, conservatively styled vehicles that actually made them gobs of money. During the early EV years, electrics were the shiny thing to show off at the car show. Now, something of the old dynamic has come to the electric sector.
Acura and Chrysler brought wild concepts to Los Angeles that were meant to signify the direction of their EVs to come. But most of the EVs in production looked far more familiar. Beyond the new hulking models from Hyundai and Kia, much of what’s on offer includes long-standing models, but in EV (Chevy Equinox and Blazer) or plug-in hybrid (Jeep Grand Cherokee and Wrangler) configurations. One of the most “interesting” EVs on the show floor was the Cybertruck, which sat quietly in a barely-staffed display of Tesla vehicles. (Elon Musk reveals his projects at separate Tesla events, a strategy more carmakers have begun to steal as a way to avoid sharing the spotlight at a car show.)
The other reason boring isn’t bad: It’s what the people want. The majority of drivers don’t buy an exotic, fun vehicle. They buy a handsome, spacious car they can afford. That last part, of course, is where the problem kicks in.
We don’t yet know the price of the Ioniq 9, but it’s likely to be in the neighborhood of Kia’s three-row electric, the EV9, which starts in the mid-$50,000s and can rise steeply from there. Stellantis’ forthcoming push into the EV market will start with not only pricey premium Jeep SUVs, but also some fun, though relatively expensive, vehicles like the heralded Ramcharger extended-range EV truck and the Dodge Charger Daytona, an attempt to apply machismo-oozing, alpha-male muscle-car marketing to an electric vehicle.
You can see the rationale. It costs a lot to build a battery big enough to power a big EV, so they’re going to be priced higher. Helpfully for the car brands, Americans have proven they will pay a premium for size and power. That’s not to say we’re entering an era of nothing but bloated EV battleships. Models such as the overpowered electric Dodge Charger and Kia EV9 GT will reveal the appetite for performance EVs. Smaller models like the revived Chevy Bolt and Kia’s EV3, already on sale overseas, are coming to America, tax credit or not.
The question for the legacy car companies is where to go from here. It takes years to bring a vehicle from idea to production, so the models on offer today were conceived in a time when big federal support for EVs was in place to buoy the industry through its transition. Now, though, the automakers have some clear uncertainty about what to say.
Chevy, having revealed new electrics like the Equinox EV elsewhere, did not hold a media conference at the L.A. show. Ford, which is having a hellacious time losing money on its EVs, used its time to talk up combustion vehicles including a new version of the palatial Expedition, one of the oversized gas-guzzlers that defined the first SUV craze of the 1990s.
If it’s true that the death of federal subsidies will send EV sales into a slump, we may see messaging from Detroit and elsewhere that feels decidedly retro, with very profitable combustion front-and-center and the all-electric future suddenly less of a talking point. Whatever happens at the federal level, EVs aren’t going away. But as they become a core part of the car business, they are going to get less exciting.
Current conditions: Parts of southwest France that were freezing last week are now experiencing record high temperatures • Forecasters are monitoring a storm system that could become Australia’s first named tropical cyclone of this season • The Colorado Rockies could get several feet of snow today and tomorrow.
This year’s Atlantic hurricane season caused an estimated $500 billion in damage and economic losses, according to AccuWeather. “For perspective, this would equate to nearly 2% of the nation’s gross domestic product,” said AccuWeather Chief Meteorologist Jon Porter. The figure accounts for long-term economic impacts including job losses, medical costs, drops in tourism, and recovery expenses. “The combination of extremely warm water temperatures, a shift toward a La Niña pattern and favorable conditions for development created the perfect storm for what AccuWeather experts called ‘a supercharged hurricane season,’” said AccuWeather lead hurricane expert Alex DaSilva. “This was an exceptionally powerful and destructive year for hurricanes in America, despite an unusual and historic lull during the climatological peak of the season.”

This year’s hurricane season produced 18 named storms and 11 hurricanes. Five hurricanes made landfall, two of which were major storms. According to NOAA, an “average” season produces 14 named storms, seven hurricanes, and three major hurricanes. The season comes to an end on November 30.
California Gov. Gavin Newsom announced yesterday that if President-elect Donald Trump scraps the $7,500 EV tax credit, California will consider reviving its Clean Vehicle Rebate Program. The CVRP ran from 2010 to 2023 and helped fund nearly 600,000 EV purchases by offering rebates that started at $5,000 and increased to $7,500. But the program as it is now would exclude Tesla’s vehicles, because it is aimed at encouraging market competition, and Tesla already has a large share of the California market. Tesla CEO Elon Musk, who has cozied up to Trump, called California’s potential exclusion of Tesla “insane,” though he has said he’s okay with Trump nixing the federal subsidies. Newsom would need to go through the State Legislature to revive the program.
President-elect Donald Trump said yesterday he would impose steep new tariffs on all goods imported from China, Canada, and Mexico on day one of his presidency in a bid to stop “drugs” and “illegal aliens” from entering the United States. Specifically, Trump threatened Canada and Mexico each with a 25% tariff, and China with a 10% hike on existing levies. Such moves against three key U.S. trade partners would have major ramifications across many sectors, including the auto industry. Many car companies import vehicles and parts from plants in Mexico. The Canadian government responded with a statement reminding everyone that “Canada is essential to U.S. domestic energy supply, and last year 60% of U.S. crude oil imports originated in Canada.” Tariffs would be paid by U.S. companies buying the imported goods, and those costs would likely trickle down to consumers.
Amazon workers across the world plan to begin striking and protesting on Black Friday “to demand justice, fairness, and accountability” from the online retail giant. The protests are organized by the UNI Global Union’s Make Amazon Pay Campaign, which calls for better working conditions for employees and a commitment to “real environmental sustainability.” Workers in more than 20 countries including the U.S. are expected to join the protests, which will continue through Cyber Monday. Amazon’s carbon emissions last year totalled 68.8 million metric tons. That’s about 3% below 2022 levels, but more than 30% above 2019 levels.
Researchers from MIT have developed an AI tool called the “Earth Intelligence Engine” that can simulate realistic satellite images to show people what an area would look like if flooded by extreme weather. “Visualizing the potential impacts of a hurricane on people’s homes before it hits can help residents prepare and decide whether to evacuate,” wrote Jennifer Chu at MIT News. The team found that AI alone tended to “hallucinate,” generating images of flooding in areas that aren’t actually susceptible to a deluge. But when combined with a science-backed flood model, the tool became more accurate. “One of the biggest challenges is encouraging people to evacuate when they are at risk,” said MIT’s Björn Lütjens, who led the research. “Maybe this could be another visualization to help increase that readiness.” The tool is still in development and is available online. Here is an image it generated of flooding in Texas:
