The end may be in sight, but it’s not here yet.
Are interest rates going to go down? The market will have to wait.
Following a Tuesday report showing steady consumer prices in May and prices overall only rising 3.3% in the past year, the Federal Reserve held steady on interest rates, releasing a projection Wednesday showing just one rate cut this year.
If rates do indeed fall this year (or next, when the Fed is projecting four cuts), that would be a big relief to renewable developers. There’s been an unprecedented flow of money into the sector in the past few years — whether from tax credits from the Inflation Reduction Act or power purchase agreements from utilities and corporations that want to decarbonize, you name it — but it’s come at the same time as projects have gotten more expensive to undertake. That’s in terms of labor and supplies, but also the most important part of any project: money.
“In the near term, investors are looking for market rates to fall to reduce financing costs — the Fed cutting the base rate could greatly help this along,” Srinivasan Santhakumar, senior research analyst at Wood Mackenzie, told me in an email.
Interest rates don’t affect every project equally. Renewables tend to be capital intensive, meaning that a higher portion of their costs are in building them as opposed to operating them. For an offshore wind turbine project, almost 70% of the expenditure comes from capital, whereas with a combined-cycle natural gas turbine plant it’s less than 20%, according to Wood Mackenzie data.
That’s because, in the case of wind and solar, the “fuel” is free, unlike with natural gas and other fossil-based energy sources. This means that developers have to fund more of the project upfront with borrowed money, which means a bigger hit from higher interest rates. According to an analysis by the investment bank Lazard, when the cost of debt is 5%, the levelized cost of an offshore wind project is $88 per megawatt-hour; when the cost of debt rises to 8%, the levelized cost rises to $118. For a combined cycle gas plant, the levelized cost per megawatt-hour rises from $66 to just $76.
“You’re really sensitive to interest rates” as a renewable developer, as Tim Latimer, the chief executive officer of the geothermal startup Fervo, explained to me. “That’s a big investment up front.”
In some sense, renewables economics have been a victim of their own success, Latimer said. Because there are lots of buyers for 15 years’ worth of renewable electricity and no risk of fuel costs surging or falling dramatically, the “spread” that renewable projects demand over risk-free rates is much smaller than for natural gas projects. But that means as rates rise, the spread shrinks more with renewables. “That has a much bigger relative impact on the economics,” Latimer said.
Geothermal projects have similar economics to other renewables, Latimer said, and being able to sell power to offtakers has helped protect the finances of Fervo’s projects.
Democratic Senators Sheldon Whitehouse and Elizabeth Warren have pressed Federal Reserve chair Jerome Powell on the high rates, citing the effect on renewable investments. “Your decision to rapidly raise interest rates beginning in 2022, and the potential that they may remain too high for too long, has halted advances in deploying renewable energy technologies and delayed significant climate and economic benefits from these projects,” the two wrote in a letter to Powell in March.
Executives from some of the world’s biggest renewables companies have been singing this song, as well. “Renewable energy in general is very, very susceptible to rising interest rates and offshore wind, even the most of all of the renewable energy sectors because it's so capital intensive. Our fuel is free, we say, but our fuel is really the cost of capital because we put so much capital out upfront,” Orsted Americas chief executive officer David Hardy told Bloomberg.
In a May earnings call, Orsted’s global chief executive, Mads Nipper, told investors, “It’s impossible to say whether [costs] have peaked yet, and on the way down, as that will hinge, very much, on the macroeconomic factors, and the rates, specifically.”
The premium renewables can yield over government debt has shrunk dramatically since 2020, BloombergNEF analyst Atin Jain said. In response, developers have increased prices for power purchase agreements, knowing that they can do so thanks to the demand for their clean electrons. But that also means more expensive power when the deals are struck, and in the case of several offshore wind projects in the Northeast, price increases can sometimes mean the deals never get done at all, even in spite of generous IRA tax credits.
“Higher interest rates are driving up project costs and [power purchase agreement] costs as well,” explained Michael Arndt, the president of Recurrent Energy, at a forum hosted by the American Council on Renewable Energy. “Being able to bring in more tax equity is a big offset to a higher interest rate environment.”
According to BNEF data, developers have tried to shorten the term of their borrowing, aiming to avoid getting locked into higher rates for a long time, while also going to the bond market for financing as opposed to bank loans, which typically means paying a lower rate. This then advantages longer tenured and more established developers who are better able to access the bond market. As Esper Nemi, the chief financial officer of the green energy giant Brookfield Renewable Partners, said in a May earnings call, “Our access to scale capital means we can execute on large opportunities where there are fewer viable partners and risk adjusted returns can therefore be very attractive.”
“Where possible, if you’re a creditworthy issuer and you’re more financially stable and have the ability to make regular interest payments, you have been viewed attractively by the bond market,” Jain told me. Bond issuance by utilities and renewable developers has more than doubled since before the pandemic, according to BNEF data. “That’s how people are navigating this environment: cutting loan tenors, doubling down on bonds. Everyone is hoping that though they have to tap more expensive debt now they’ll be able to refinance those loans,” Jain said.
How many people will be able refinance remains to be seen. “Developers with deeper balance sheets are able to navigate this a little bit better than smaller or midsize companies,” Jain added.
Latimer said that higher rates could be particularly challenging to first of a kind projects. Investors have a return they want a new project to generate and that figure moves up with interest rates.
“The return hurdle that you need to hit to entice capital that views your project as a new development and new technology moves up with interest rates,” Latimer told me. “Your project economics have to be that much better relative to what your baseline was before because everyone has higher return expectations.”

A new Data for Progress poll provided exclusively to Heatmap shows steep declines in support for the CEO and his business.
Nearly half of likely U.S. voters say that Elon Musk’s behavior has made them less likely to buy or lease a Tesla, a much higher figure than similar polls have found in the past, according to a new Data for Progress poll provided exclusively to Heatmap.
The new poll, which surveyed a national sample of voters over the President’s Day weekend, shows a deteriorating public relations situation for Musk, who has become one of the most powerful individuals in President Donald Trump’s new administration.
Exactly half of likely voters now hold an unfavorable view of Musk, a significant increase since Trump’s election. Democrats and independents are particularly sour on the Tesla CEO, with 81% of Democrats and 51% of independents reporting unfavorable views.
By comparison, 42% of likely voters — and 71% of Republicans — report a favorable opinion of Musk. The billionaire is now eight points underwater with Americans, with 39% of likely voters reporting “very” unfavorable views. Musk is much more unpopular than President Donald Trump, who is only about 1.5 points underwater in FiveThirtyEight’s national polling average.
Perhaps more ominous for Musk is that many Americans seem to be turning away from Tesla, the EV manufacturer he leads. About 45% of likely U.S. voters say that they are less likely to buy or lease a Tesla because of Musk, according to the new poll.
That rejection is concentrated among Democrats and independents, who make up an overwhelming share of EV buyers in America. Two-thirds of Democrats now say that Musk has made them less likely to buy a Tesla, with the vast majority of that group saying they are “much less likely” to do so. Half of independents report that Musk has turned them off Teslas. Some 21% of Democrats and 38% of independents say that Musk hasn’t affected their Tesla buying decision one way or the other.
Republicans, who account for a much smaller share of the EV market, do not seem to be rushing in to fill the gap. More than half of Republicans, or 55%, say that Musk has had no impact on their decision to buy or lease a Tesla. While 23% of Republicans say that Musk has made them more likely to buy a Tesla, roughly the same share — 22% — say that he has made them less likely.
Tesla is the world’s most valuable automaker, worth more than the next dozen or so largest automakers combined. Musk’s stake in the company makes up more than a third of his wealth, according to Bloomberg.
Thanks in part to its aging vehicle line-up, Tesla’s total sales fell last year for the first time ever, although it reported record deliveries in the fourth quarter. The United States was Tesla’s largest market by revenue in 2024.
Musk hasn’t always been such a potential drag on Tesla’s reach. In February 2023, soon after Musk’s purchase of Twitter, Heatmap asked U.S. adults whether the billionaire had made them more or less likely to buy or lease a Tesla. Only about 29% of Americans reported that Musk had made them less likely, while 26% said that he made them more likely.
When Heatmap asked the question again in November 2023, the results did not change. The same 29% of U.S. adults said that Musk had made them less likely to buy a Tesla.
By comparison, 45% of likely U.S. voters now say that Musk makes them less likely to get a Tesla, and only 17% say that he has made them more likely to do so. (Note that this new result isn’t perfectly comparable with the old surveys, because while the new poll surveyed likely voters , the 2023 surveys asked all U.S. adults.)
Musk’s popularity has also tumbled in that time. As recently as September, Musk was eight points above water in Data for Progress’ polling of likely U.S. voters.
Since then, Musk has become a power player in Republican politics and been made de facto leader of the Department of Government Efficiency. He has overseen thousands of layoffs and sought to win access to computer networks at many federal agencies, including the Department of Energy, the Social Security Administration, and the IRS, leading some longtime officials to resign in protest.
Today, he is eight points underwater — a 16-point drop in five months.
“We definitely have seen a decline, which I think has mirrored other pollsters out there who have been asking this question, especially post-election,” Data for Progress spokesperson Abby Springs, told me .
The new Data for Progress poll surveyed more than 1,200 likely voters around the country on Friday, February 14, and Saturday, February 15. Its results were weighted by demographics, geography, and recalled presidential vote. The margin of error was 3 percentage points.
On Washington walk-outs, Climeworks, and HSBC’s net-zero goals
Current conditions: Severe storms in South Africa spawned a tornado that damaged hundreds of homes • Snow is falling on parts of Kentucky and Tennessee still recovering from recent deadly floods • It is minus 39 degrees Fahrenheit today in Bismarck, North Dakota, which breaks a daily record set back in 1910.
Denise Cheung, Washington’s top federal prosecutor, resigned yesterday after refusing the Trump administratin’s instructions to open a grand jury investigation of climate grants issued by the Environmental Protection Agency during the Biden administration. Last week EPA Administrator Lee Zeldin announced that the agency would be seeking to revoke $20 billion worth of grants issued to nonprofits through the Greenhouse Gas Reduction Fund for climate mitigation and adaptation initiatives, suggesting that the distribution of this money was rushed and wasteful of taxpayer dollars. In her resignation letter, Cheung said she didn’t believe there was enough evidence to support grand jury subpoenas.
Failed battery maker Northvolt will sell its industrial battery unit to Scania, a Swedish truckmaker. The company launched in 2016 and became Europe’s biggest and best-funded battery startup. But mismanagement, production delays, overreliance on Chinese equipment, and other issues led to its collapse. It filed for Chapter 11 bankruptcy protection in November and its CEO resigned. As Reutersreported, Northvolt’s industrial battery business was “one of its few profitable units,” and Scania was a customer. A spokesperson said the acquisition “will provide access to a highly skilled and experienced team and a strong portfolio of battery systems … for industrial segments, such as construction and mining, complementing Scania's current customer offering.”
TikTok is partnering with Climeworks to remove 5,100 tons of carbon dioxide from the air through 2030, the companies announced today. The short-video platform’s head of sustainability, Ian Gill, said the company had considered several carbon removal providers, but that “Climeworks provided a solution that meets our highest standards and aligns perfectly with our sustainability strategy as we work toward carbon neutrality by 2030.” The swiss carbon capture startup will rely on direct air capture technology, biochar, and reforestation for the removal. In a statement, Climeworks also announced a smaller partnership with a UK-based distillery, and said the deals “highlight the growing demand for carbon removal solutions across different industries.”
HSBC, Europe’s biggest bank, is abandoning its 2030 net-zero goal and pushing it back by 20 years. The 2030 target was for the bank’s own operations, travel, and supply chain, which, as The Guardiannoted, is “arguably a much easier goal than cutting the emissions of its loan portfolio and client base.” But in its annual report, HSBC said it’s been harder than expected to decarbonize supply chains, forcing it to reconsider. Back in October the bank removed its chief sustainability officer role from the executive board, which sparked concerns that it would walk back on its climate commitments. It’s also reviewing emissions targets linked to loans, and considering weakening the environmental goals in its CEO’s pay package.
A group of 27 research teams has been given £81 million (about $102 million) to look for signs of two key climate change tipping points and create an “early warning system” for the world. The tipping points in focus are the collapse of the Greenland ice sheet, and the collapse of north Atlantic ocean currents. The program, funded by the UK’s Advanced Research and Invention Agency, will last for five years. Researchers will use a variety of monitoring and measuring methods, from seismic instruments to artificial intelligence. “The fantastic range of teams tackling this challenge from different angles, yet working together in a coordinated fashion, makes this program a unique opportunity,” said Dr. Reinhard Schiemann, a climate scientist at the University of Reading.
In 2024, China alone invested almost as much in clean energy technologies as the entire world did in fossil fuels.

Rob and Jesse get real on energy prices with PowerLines’ Charles Hua.
The most important energy regulators in the United States aren’t all in the federal government. Each state has its own public utility commission, a set of elected or appointed officials who regulate local power companies. This set of 200 individuals wield an enormous amount of power — they oversee 1% of U.S. GDP — but they’re often outmatched by local utility lobbyists and overlooked in discussions from climate advocates.
Charles Hua wants to change that. He is the founder and executive director of PowerLines, a new nonprofit engaging with America’s public utility commissions about how to deliver economic growth while keeping electricity rates — and greenhouse gas emissions — low. Charles previously advised the U.S. Department of Energy on developing its grid modernization strategy and analyzed energy policy for the Lawrence Berkeley National Laboratory.
On this week’s episode of Shift Key, Rob and Jesse talk to Charles about why PUCs matter, why they might be a rare spot for progress over the next four years, and why (and how) normal people should talk to their local public utility commissioner. Shift Key is hosted by Jesse Jenkins, a professor of energy systems engineering at Princeton University, and Robinson Meyer, Heatmap’s executive editor.

Here is an excerpt from our conversation:
Robinson Meyer: I want to pivot a bit and ask something that I think Jesse and I have talked about, something that you and I have talked about, Charles, is that the PUCs are going to be very important during the second Trump administration, and there’s a lot of possibilities, or there’s some possibilities for progress during the Trump administration, but there’s also some risks. So let’s start here: As you survey the state utility landscape, what are you worried about over the next four years or so? What should people be paying attention to at the PUC level?
Charle Hua: I think everything that we’re hearing around AI data centers, load growth, those are decisions that ultimately state public utility commissioners are going to make. And that’s because utilities are significantly revising their load forecasts.
Just take Georgia Power — which I know you talked about last episode at the end — which, in 2022, just two years ago, their projected load forecast for the end of the decade was about 400 megawatts. And then a year later, they increased that to 6,600 megawatts. So that’s a near 17x increase. And if you look at what happens with the 2023 Georgia Power IRP, I think the regulators were caught flat footed about just how much load would actually materialize from the data centers and what the impact on customer bills would be.
Meyer:And what’s an IRP? Can you just give us ...
Hua: Yes, sorry. So, integrated resource plan. So that’s the process by which utilities spell out how they’re proposing to make investments over a long term planning horizon, generally anywhere from 15 to 30 years. And if we look at, again, last year’s integrated resource plan in Georgia, there was significant proposed new fossil fuel infrastructure that was ultimately fully approved by the public service commission.
And there’s real questions about how consumer interests are or aren’t protected with decisions like that — in part because, if we look at what’s actually driving things like rising utility bills, which is a huge problem. I mean, one in three Americans can’t pay their utility bills, which have increased 20% over the last two years, two to three years. One of the biggest drivers of that is volatile gas prices that are exposed to international markets. And there’s real concern that if states are doubling down on gas investments and customers shoulder 100% of the risk of that gas price volatility that customers’ bills will only continue to grow.
And I think what’s going on in Georgia, for instance, is a harbinger of what’s to come nationally. In many ways, it’s the epitome of the U.S. clean energy transition, where there’s both a lot of clean energy investment that’s happening with all of the new growth in manufacturing facilities in Georgia, but if you actually peel beneath the layers and you see what’s going on internal to the state as it relates to its electricity mix, there’s a lot to be concerned about.
And the question is, are we going to have public utility commissions and regulatory bodies that can adequately protect the public interest in making these decisions going forward? And I think that’s the million dollar question.
