Cooking gas could just become ridiculously expensive.
There are plenty of reasons to consider abandoning your gas stove. Electric cooking won’t slowly poison you with nitrogen dioxide or send planet-warming carbon dioxide into the atmosphere. Many cooks — including The New York Times’ Melissa Clark — are surprised at how much they prefer today’s state-of-the-art electric cooktops, known as induction stoves, despite initial skepticism.
But there’s another factor that’s a lot more likely to send people fleeing from the blue flame. Despite the culture war skirmish over gas stoves this past winter, which saw conservatives talking about the appliances as if they were constitutionally-protected AR-15s and progressives hand wringing about beloved Wolf and Viking ranges, widespread adoption of induction won’t happen through comparison shopping. It will happen because cooking with gas could become ridiculously expensive.
At the moment, the opposite is true. Newer induction ranges cost more than gas alternatives, and may even require a pricy electrical upgrade. Gas is also still generally cheaper than electricity.
But the thing about your gas bill is that it doesn’t just cover the cost of the fuel itself. It also covers the construction and maintenance of all the infrastructure required to deliver it to your home. Those costs are spread across the entire customer base. And that customer base is set to contract.
A handful of climate-forward cities and states have stopped allowing newly constructed buildings to hook up to natural gas. More importantly, billions of dollars of incentives in President Biden’s Inflation Reduction Act, along with state-level subsidies, are designed to push Americans to electrify their homes, including their space heating and hot water systems, as well as their stoves. Higher natural gas costs in recent months stemming from the war in Ukraine have also made decarbonizing where you live a lot more attractive.
But as the overall pool of gas customers shrinks and demand for gas declines, the cost of maintaining the system may not. That means those clinging to their gas stoves could see the cost of roasting a chicken skyrocket as they become saddled with a larger portion of the bill for maintaining a vast network of gas delivery pipelines.
Often referred to as the gas utility “death spiral,” the phenomenon is self-perpetuating. Higher bills motivate more customers to get off gas, leading to higher bills, and so on. In a 2019 report looking at how this could play out in the context of California’s aggressive decarbonization policies, the consulting firm Gridworks called it “a quintessential train wreck unfolding in slow motion.” The first 10% reduction in gas demand would only increase rates by about 10%, but as demand drops further, the effect starts to compound.
“There's this hockey stick curve that gets steeper and steeper,” said Mike Henchen, who leads the carbon-free buildings program at the clean energy nonprofit RMI, and was not involved in the Gridworks report. “By the time you cut gas demand about 60%, gas rates have doubled. By the time you cut gas use 80%, they’ve more than tripled.”
Gridworks modeled a scenario with high levels of electrification, shown to be the lowest cost path to achieving California’s emissions targets, and found that residential gas rates could increase from about $1.50 per therm to $19 by 2050.
That’s just one estimate. It’s hard to predict how many people will take advantage of these currently voluntary programs, or how quickly remaining customers will see the effects in their utilities bills. But another study conducted by economists at the University of California, Berkeley, confirms that the risk is real. The authors looked at historical evidence showing that when U.S. gas utilities have lost customers in the past, rates for those remaining have increased. They used the data to predict how a shift to electric buildings could affect gas ratepayers in the future, and estimated that if the pool shrank by 15% by 2030 and 40% by 2040, it would translate into annual bill increases of $31 and $116 per remaining customer, respectively.
It’s not just those early adopters who go all-electric that contribute to the problem. Gas companies, whose business model is threatened by electrification, would prefer a transition to pumping low-carbon fuels like hydrogen and renewable natural gas through their pipelines. Rather than anticipating reduced demand for their product, they’re pouring record amounts of cash into expanding. Data collected by the American Gas Association, a trade group for gas utilities, show that the industry’s annual capital expenditures have more than tripled since 2010. Growing even faster is the amount utilities spend on the distribution system that delivers gas to people’s homes, which has quadrupled.
“Spending is going up even as the long term outlook for demand is going down,” said Henchen. “So those two trends are gonna create problems.”
The reasons are twofold. Even though the push to electrify is ramping up, the customer exodus hasn’t hit yet and many utilities are actually expanding their systems to reach new customers. Meanwhile, older pipelines are plagued by leaks and other safety hazards. Utilities spend millions of dollars a year replacing pipes — costs that are then recovered through rates over the course of decades.
“It is unreasonable to expect that these costs can be recovered from ratepayers over many decades,” the Building Decarbonization Coalition, a nonprofit working on getting fossil fuels out of buildings, wrote in a recent report looking at the issue in New York State. The group questioned how utilities would be able to recover pipeline expansion and replacement costs when New York’s climate policies are encouraging households to leave the gas system. It urged the state’s utility commission to “intervene before the economics of the state’s gas networks unravel.”
These warnings are worth taking seriously because it’s not just Senator Joe Manchin of West Virginia and other gas diehards who’ll be affected by the gas market falling apart. The aforementioned studies about the death spiral point to higher costs disproportionately falling on lower-income households and people of color.
Researchers who have studied the gas death spiral say there are a number of ways policymakers and regulators can manage the transition to avoid steep rate hikes.
One option is to repeal existing laws in many states that say gas utilities have a “duty to serve” customers and must hook them up to gas for free, allowing them to subsidize the cost of extending gas mains across their customer bases. California became the first state to take this step last year, and the move is estimated to save customers more than $160 million annually.
Another is to re-imagine pipe replacement programs, and strategically electrify neighborhoods that need replacements. But nothing like this has been tried yet, and it’s not yet clear how to pay for it, or what to do if any of the households refuse to make the change.
Other ideas include requiring those who leave the gas system to pay an exit fee, or to accelerate the depreciation schedules of new assets to better reflect how long they will be needed in a decarbonizing world.
Even if spiraling costs can be mitigated, Henchen said they’re unlikely to be entirely avoided. “It’s going to be this lagging trend that takes time to build up,” he said. “People probably won’t see it for 15 years or more from now.”
You may not be dreaming about an electric stove today, but let’s talk again in 2038.

On prepurchase agreements, Al Gore, and Norway’s EVs
Current conditions: Ecuador’s government-enforced blackouts will begin tomorrow night as drought threatens hydroelectric plants • Storm Boris is causing flooding in parts of Italy • Montana could see very heavy rainfall and flash flooding today.
Frontier, a coalition of carbon removal buyers, announced this morning a fourth round of prepurchase agreements, worth $4.5 million. The coalition facilitated agreements with nine suppliers to remove carbon from the atmosphere on behalf of five of Frontier’s buyers: Stripe, Shopify, Alphabet, H&M Group, and Match. The removal projects are located across six countries and utilize a range of techniques, including rock weathering, direct air capture, and ocean alkalinity enhancement. In a press release, Frontier said “a significant number of companies in this purchase cycle are integrating carbon removal into existing large-scale industries. This strategy can reduce costs and accelerate scale-up relative to standalone carbon removal projects.”

Brazil’s worst drought on record, now in its second year, has caused water levels in the rivers that run through the Amazon to fall to historic lows, and some have even dried up entirely. One key tributary that supplies the mighty Amazon River, the Solimoes, has water levels that are 14 feet below average for the first half of September. The drought is fueling numerous large fires, many of which were started by humans but have plenty of dry vegetation to keep them going.

According to data from Brazil’s National Institute for Space Research, almost half of the Amazon fires are burning pristine forest. This is unusual, The New York Timesreported, and “means fighting deforestation in the Amazon is no longer enough to stop fires.” The Amazon rainforest is one of the world’s most important carbon sinks. If it collapses, it could release huge amounts of carbon into the atmosphere, exacerbating the climate crisis. Researchers with World Weather Attribution say climate change is the main driver of the Amazon’s ongoing drought. “Climate change is no longer something to worry about in the future, 10 or 20 years from now,” Greenpeace spokesperson Romulo Batista toldReuters. “It’s here and it’s here with much more force than we expected.”
A coalition of some of the world’s most prominent shipping and carrier companies is piloting the “first-ever U.S. over-the-road electrified corridor.” Participants include AIT Worldwide Logistics, DB Schenker, Maersk, Microsoft, and PepsiCo, who will drive their long-haul heavy-duty electric trucks along the I-10 corridor between L.A. and El Paso to identify pain points and share learnings in an effort to hasten the decarbonization of land freight. Terawatt Infrastructure will provide the charging infrastructure for the corridor with six of its own charging hubs. Terawatt’s website says it has 14 sites under development, four of which are expected to come online this year. Heavy-duty vehicles account for a quarter of transport-related greenhouse gas emissions in the U.S. The new coalition is supported by the global nonprofit Smart Freight Centre.
Former U.S. Vice President Al Gore’s green asset management business, Generation Investment Management, put out its eighth annual Sustainability Trends Report this week. The paper is packed full of interesting insights (both uplifting and depressing), but one stands out. It says upgrading the power grid is “the critical issue to get the energy transition moving faster in the big, developed economies.” It includes this graphic showing the cumulative backlog of renewable-energy projects wanting to connect to the grid in the U.S.:

Gore has been doing the media rounds this week. He told the Financial Times that a Trump victory in November “would be very bad.” “Most climate activists that I know in the United States believe that the single most important near-term decision America can make with regard to climate is who is the next president. It’s a bit of a Manichaean choice.” But, he added that the energy transition was, at this point, “unstoppable.”
In case you missed it: Norway has become the first country in the world to have more electric vehicles on the road than gas-powered cars. Diesel still reigns supreme in terms of registered vehicles, but the share of fully electric cars registered is now larger than the share of cars that run on gasoline. The director of the Norwegian road federation said he expects EVs will overtake diesel cars, too, by 2026. EVs already make up the vast majority (94%!) of new vehicle sales in Norway, and could very well approach 100% sometime next year.
A recent study finds that most people have a tendency to grossly underestimate the average carbon footprint of the richest individuals in society, while overestimating the carbon footprint of the poorest individuals.
Geothermal is getting closer to the big time. Last week, Fervo Energy — arguably the country’s leading enhanced geothermal company — announced that its Utah demonstration project had achieved record production capacity. The new approach termed “enhanced geothermal,” which borrows drilling techniques and expertise from the oil and gas industry, seems poised to become a big player on America’s clean, 24/7 power grid of the future.
Why is geothermal so hot? How soon could it appear on the grid — and why does it have advantages that other zero-carbon technologies don’t? On this week’s episode of Shift Key, Rob and Jesse speak with a practitioner and an expert in the world of enhanced geothermal. Sarah Jewett is the vice president of strategy at Fervo Energy, which she joined after several years in the oil and gas industry. Wilson Ricks is a doctoral student of mechanical and aerospace engineering at Princeton University, where he studies macro-energy systems modeling. Shift Key is hosted by Robinson Meyer, the founding executive editor of Heatmap, and Jesse Jenkins, a professor of energy systems engineering at Princeton University.

Here is an excerpt from our conversation:
Robinson Meyer: I just wanted to hit a different note here, which is, Sarah, you’ve alluded a few times to your past in the oil and gas industry. I think this is true across Fervo, is that of course, the technologies we’re discussing here are fracking derived. What has your background in the oil and gas industry and hydrocarbons taught you that you think about at Fervo now, and developing geothermal as a resource?
Sarah Jewett: There are so many things. I mean, I’m thinking about my time in the oil and gas industry daily. And you’re exactly right, I think today about 60% of Fervo’s employees come from the oil and gas industry. And because we are only just about to start construction on our first power facility, the percentage of contractors and field workers from the oil and gas industry is much higher than 60%.
Jesse Jenkins: Right, you can’t go and hire a bunch of people with geothermal experience when there is no large-scale geothermal industry to pull from.
Jewett: That’s right. That’s right. And so the oil and gas industry, I think, has taught us, so many different types of things. I mean, we can’t really exist without thinking about the history of the oil and gas industry — even, you know, Wilson and I are sort of comparing our learning rates to learning rates observed in various different oil and gas basins by different operators, so you can see a lot of prior technological pathways.
I mean, first off, we’re just using off the shelf technology that has been proven and tested in the oil and gas industry over the last 25 years, which has been, really, the reason why geothermal is able to have this big new unlock, because we’re using all of this off the shelf technology that now exists. It’s not like the early 2000s, where there was a single bit we could have tried. Now there are a ton of different bits that are available to us that we can try and say, how is this working? How is this working? How’s this working?
So I think, from a technological perspective, it’s helpful. And then from just an industry that has set a solid example it’s been really helpful, and that can be leveraged in a number of different ways. Learning rates, for example; how to set up supply chains in remote areas, for example; how to engage with and interact with communities. I think we’ve seen examples of oil and gas doing that well and doing it poorly. And I’ve gotten to observe firsthand the oil and gas industry doing it well and doing it poorly.
And so I’ve gotten to learn a lot about how we need to treat those around us, explain to them what it is that we’re doing, how open we need to be. And I think that has been immensely helpful as we’ve crafted the role that we’re going to play in these communities at large.
Wilson Ricks: I think it’s also interesting to talk about the connection to the oil and gas industry from the perspective of the political economy of the energy transition, specifically because you hear policymakers talk all the time about retraining workers from these legacy industries that, if we’re serious about decarbonizing, will unavoidably have to contract — and, you know, getting those people involved in clean energy, in these new industries.
And often that’s taking drillers and retraining some kind of very different job — or coal miners — into battery manufacturers. This is almost exactly one to one. Like Sarah said, there’s additional expertise and experience that you need to get really good at doing this in the geothermal context. But for the most part, you are taking the exact same skills and just reapplying them, and so it allows for both a potentially very smooth transition of workforces, and also it allows for scale-up of enhanced geothermal to proceed much more smoothly than it potentially would if you had to kind of train an entire workforce from scratch to just do this.

Why the new “reasoning” models might gobble up more electricity — at least in the short term
What happens when artificial intelligence takes some time to think?
The newest set of models from OpenAI, o1-mini and o1-preview, exhibit more “reasoning” than existing large language models and associated interfaces, which spit out answers to prompts almost instantaneously.
Instead, the new model will sometimes “think” for as long as a minute or two. “Through training, they learn to refine their thinking process, try different strategies, and recognize their mistakes,” OpenAI announced in a blog post last week. The company said these models perform better than their existing ones on some tasks, especially related to math and science. “This is a significant advancement and represents a new level of AI capability,” the company said.
But is it also a significant advancement in energy usage?
In the short run at least, almost certainly, as spending more time “thinking” and generating more text will require more computing power. As Erik Johannes Husom, a researcher at SINTEF Digital, a Norwegian research organization, told me, “It looks like we’re going to get another acceleration of generative AI’s carbon footprint.”
Discussion of energy use and large language models has been dominated by the gargantuan requirements for “training,” essentially running a massive set of equations through a corpus of text from the internet. This requires hardware on the scale of tens of thousands of graphical processing units and an estimated 50 gigawatt-hours of electricity to run.
Training GPT-4 cost “more than” $100 million OpenAI chief executive Sam Altman has said; the next generation models will likely cost around $1 billion, according to Anthropic chief executive Dario Amodei, a figure that might balloon to $100 billion for further generation models, according to Oracle founder Larry Ellison.
While a huge portion of these costs are hardware, the energy consumption is considerable as well. (Meta reported that when training its Llama 3 models, power would sometimes fluctuate by “tens of megawatts,” enough to power thousands of homes). It’s no wonder that OpenAI’s chief executive Sam Altman has put hundreds of millions of dollars into a fusion company.
But the models are not simply trained, they're used out in the world, generating outputs (think of what ChatGPT spits back at you). This process tends to be comparable to other common activities like streaming Netflix or using a lightbulb. This can be done with different hardware and the process is more distributed and less energy intensive.
As large language models are being developed, most computational power — and therefore most electricity — is used on training, Charlie Snell, a PhD student at University of California at Berkeley who studies artificial intelligence, told me. “For a long time training was the dominant term in computing because people weren’t using models much.” But as these models become more popular, that balance could shift.
“There will be a tipping point depending on the user load, when the total energy consumed by the inference requests is larger than the training,” said Jovan Stojkovic, a graduate student at the University of Illinois who has written about optimizing inference in large language models.
And these new reasoning models could bring that tipping point forward because of how computationally intensive they are.
“The more output a model produces, the more computations it has performed. So, long chain-of-thoughts leads to more energy consumption,” Husom of SINTEF Digital told me.
OpenAI staffers have been downright enthusiastic about the possibilities of having more time to think, seeing it as another breakthrough in artificial intelligence that could lead to subsequent breakthroughs on a range of scientific and mathematical problems. “o1 thinks for seconds, but we aim for future versions to think for hours, days, even weeks. Inference costs will be higher, but what cost would you pay for a new cancer drug? For breakthrough batteries? For a proof of the Riemann Hypothesis? AI can be more than chatbots,” OpenAI researcher Noam Brown tweeted.
But those “hours, days, even weeks” will mean more computation and “there is no doubt that the increased performance requires a lot of computation,” Husom said, along with more carbon emissions.
But Snell told me that might not be the end of the story. It’s possible that over the long term, the overall computing demands for constructing and operating large language models will remain fixed or possibly even decline.
While “the default is that as capabilities increase, demand will increase and there will be more inference,” Snell told me, “maybe we can squeeze reasoning capability into a small model ... Maybe we spend more on inference but it’s a much smaller model.”
OpenAI hints at this possibility, describing their o1-mini as “a smaller model optimized for STEM reasoning,” in contrast to other, larger models that “are pre-trained on vast datasets” and “have broad world knowledge,” which can make them “expensive and slow for real-world applications.” OpenAI is suggesting that a model can know less but think more and deliver comparable or better results to larger models — which might mean more efficient and less energy hungry large language models.
In short, thinking might use less brain power than remembering, even if you think for a very long time.
