Power Forward Communities wants you to have a heat pump.
Getting fossil fuels out of your home is really hard. You have to find a contractor, ideally one who supports electrification and doesn’t ask why you won’t just stick with natural gas. You have to coordinate between multiple trades — electricians, plumbers, HVAC professionals — as well as lenders and utilities and permitting authorities, most of whom don’t talk to each other. You have to navigate a confusing array of finance options and incentives. You might be left feeling defeated, unable to afford the high up-front costs and unable to secure low-cost loans. And if you’re a renter, all you can do is dream.
These are not easy problems to solve. But a new initiative called Power Forward Communities has a pioneering plan to simplify the process all over the country — and it just got $2 billion to get started.
The money is part of the $20 billion the Biden administration awarded on Thursday via the Greenhouse Gas Reduction Fund, a program approved as part of the Inflation Reduction Act to provide low-cost financing options for consumers, communities, and businesses to transition to clean energy and adapt to climate change.
Power Forward Communities is made up of five core partner organizations — Rewiring America, Enterprise Community Partners, Local Initiatives Support Corporation, Habitat for Humanity, and United Way Worldwide — who will work with communities, government agencies, unions, and housing developers to decarbonize hundreds of thousands of homes and apartments between now and 2031. The coalition has committed to invest at least 75% of the financing in projects in low-income and disadvantaged communities.
That all starts with a four point plan.
First, reduce friction by creating online tools and providing community-level assistance to help homeowners navigate the decarbonization process. Rewiring America is already part of the way there with its “personal electrification planner,” which provides a rough estimate of the upfront cost, annual bill savings, and expected emissions reductions for any given project. Soon, the group will pair that with another, first-of-its-kind tool: a dataset of every electrification incentive in the country. Eventually you’ll be able to plug in your address and income and get a list of all of the programs available to help you pay for your project.
Second, invest in workforce development and create a “contractor marketplace” where building owners can go to find vetted partners for their project.
Third, create new low-cost financial products to help bridge the gap between existing incentives and project costs. Notably, Power Forward plans to allocate more than half of its loans to projects in multifamily buildings, as these buildings tend to serve renters with lower incomes, and decarbonizing them is much more capital-intensive.
The details of the finance aspect of the program are subject to change, but the group’s application for the Greenhouse Gas Reduction Fund proposes an energy efficiency loan for apartment building owners who want to make minor upgrades, which would offer an average of $30,000 per building with a 10- to 20-year term and 1% to 3% interest rate. As part of this program, Power Forward would also work with the building owner to make a plan to fully decarbonize the building down the line, and issue grants to fund the planning process. A proposed “net-zero rehab permanent loan,” meanwhile, would provide financing for full retrofits at an average of $120,000 per building.
Meanwhile, the finance options for single-family homes could be tied to predetermined “packages” of decarbonization measures that homeowners can choose from. This brings me to the fourth, and what I see as the most interesting and innovative part of the plan: the aggregation of demand.
Part of why electrification is so difficult and expensive is that it’s a bespoke process. Some buildings might need insulation, others might need electrical upgrades. Some might require new ductwork for central heat pumps, while others might be better off installing mini-split heat pumps in every zone of the house. There’s no one-size-fits-all solution.
“How do we unlock economies of scale and create an offering that could serve as many households at once?,” Nicole Staple, the head of market partnerships at Rewiring America, posed rhetorically to me in February. “That has historically been incredibly challenging given there's so much customization to heat pump design.”
But there are buildings with similar needs. If there were a way to identify them and then group the jobs together, you could start to solve a surprising number of other challenges. “That's where I think you unlock a lot of speed in [electrifying] full communities,” said Staple.
The most obvious benefit would be lowering the cost of equipment by buying in bulk. You could give suppliers better visibility into demand so they could stock up accordingly. You could help contractors plan ahead and space out jobs so that they have guaranteed work during the shoulder seasons. You could create new markets for union labor, which have historically been shut out from residential work due to the small size of the contracts and high customer acquisition costs. You could pool loans to diversify risk. You could design more effective policies to wind down the natural gas system.
The standardized packages Power Forward plans to offer will enable the group to “pre-define pricing and financial product offers, streamline underwriting and installation, and reduce financing costs,” according to its funding application. It estimates that by aggregating demand, it can reduce the remaining costs of electrification after incentives by as much as 50%.
The application also said the group has obtained letters of commitment from supply chain participants, including Home Depot and Mitsubishi, to lower equipment costs. In return, the coalition will reserve an initial $125 million over the first three years of the program as an insurance pool to guarantee $1 billion in sales volume for select partners.
To unlock all this magical potential, Rewiring America has been working on a large-scale data model to identify homes with similar characteristics, which will in turn help it figure out where there is opportunity to bundle projects in different parts of the country.
The group has also been gathering information and testing out assumptions on what will ultimately lower the costs of equipment and installation in a series of pilot projects, starting with one in the rural, mostly Black community of DeSoto, Georgia, where “107 households survive on a median income of $20,375, grapple with repeated house fires linked to propane gas usage, and strain to pay utility bills,” according to Power Forward’s application.
When I spoke to Staple a couple of months ago, she told me that about 75 households in DeSoto had expressed interest in the program thus far. Each participant would get at least one piece of equipment — a heat pump space heating system or a water heater, for example — fully subsidized. They would also be eligible for electrical upgrades or weatherization improvements as needed.
“Many of the households have not had cooling. Some have had their HVAC systems broken for literally decades,” Staple told me. “There's lots of dimensions of that community that we think help us understand how carefully we need to manage electrification projects, considering the ways that these communities have been failed.”
Power Forward had initially requested $9.5 billion to implement its plans, so it will have to go back to the drawing board over the next few months to map out what it can achieve with the $2 billion it was given. What could it have accomplished with that additional $7.5 billion?
“Our mission is to create hundreds of DeSotos, and ultimately decarbonize housing across the nation,” the coalition’s application says.

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.
On Azerbaijan’s plans, offshore wind auctions, and solar jobs
Current conditions: Thousands of firefighters are battling raging blazes in Portugal • Shanghai could be hit by another typhoon this week • More than 18 inches of rain fell in less than 24 hours in Carolina Beach, which forecasters say is a one-in-a-thousand-year event.
Azerbaijan, the host of this year’s COP29, today put forward a list of “non-negotiated” initiatives for the November climate summit that will “supplement” the official mandated program. The action plan includes the creation of a new “Climate Finance Action Fun” that will take (voluntary) contributions from fossil fuel producing countries, a call for increasing battery storage capacity, an appeal for a global “truce” during the event, and a declaration aimed at curbing methane emissions from waste (which the Financial Times noted is “only the third most common man-made source of methane, after the energy and agricultural sectors”). The plan makes no mention of furthering efforts to phase out fossil fuels in the energy system.
The Interior Department set a date for an offshore wind energy lease sale in the Gulf of Maine, an area which the government sees as suitable for developing floating offshore wind technology. The auction will take place on October 29 and cover eight areas on the Outer Continental Shelf off Massachusetts, New Hampshire, and Maine. The area could provide 13 gigawatts of offshore wind energy, if fully developed. The Biden administration has a goal of installing 30 GW of offshore wind by 2030, and has approved about half that amount so far. The DOI’s terms and conditions for the October lease sale include “stipulations designed to promote the development of a robust domestic U.S. supply chain for floating wind.” Floating offshore wind turbines can be deployed in much deeper waters than traditional offshore projects, and could therefore unlock large areas for clean power generation. Last month the government gave the green light for researchers to study floating turbines in the Gulf of Maine.
In other wind news, BP is selling its U.S. onshore wind business, bp Wind Energy. The firm’s 10 wind farm projects have a total generating capacity of 1.3 gigawatts and analysts think they could be worth $2 billion. When it comes to renewables, the fossil fuel giant said it is focusing on investing in solar growth, and onshore wind is “not aligned” with those plans.
The number of jobs in the U.S. solar industry last year grew to 279,447, up 6% from 2022, according to a new report from the nonprofit Interstate Renewable Energy Council. Utility-scale solar added 1,888 jobs in 2023, a 6.8% increase and a nice rebound from 2022, when the utility-scale solar market recorded a loss in jobs. The report warns that we might not see the same kind of growth for solar jobs in 2024, though. Residential installations have dropped, and large utility-scale projects are struggling with grid connection. The report’s authors also note that as the industry grows, it faces a shortage of skilled workers.

Most employers reported that hiring qualified solar workers was difficult, especially in installation and project development. “It’s difficult because our projects are built in very rural areas where there just aren't a lot of people,” one interviewee who works at a utility-scale solar firm said. “We strive to hire as many local people as possible because we want local communities to feel the economic impact or benefit from our projects. So in some communities where we go, it is difficult to find local people that are skilled and can perform the work.”
The torrential rain that has battered central Europe is tapering off a bit, but the danger of rising water remains. “The massive amounts of rain that fell is now working its way through the river systems and we are starting to see flooding in areas that avoided the worst of the rain,” BBC meteorologist Matt Taylor explained. The Polish city of Nysa told its 44,000 residents to leave yesterday as water rose. In the Czech Republic, 70% of the town of Litovel was submerged in 3 feet of flooding. The death toll from the disaster has risen to 18. Now the forecast is calling for heavy rain in Italy. “The catastrophic rainfall hitting central Europe is exactly what scientists expect with climate change,” Joyce Kimutai, a climate scientist with Imperial College London’s Grantham Institute, toldThe Guardian.
A recent study examining the effects of London’s ultra-low emissions zone on how students get to school found that a year after the rules came into effect, many students had switched to walking, biking, or taking public transport instead of being driven in private vehicles.
