On new 2030 projections, stronger hurricanes, and green hydrogen
Current conditions: Rare rainstorms have flooded parts of the Sahara Desert • Storm Kirk is expected to bring flooding to parts of northern France • Wyoming’s 75,000-acre Elk Fire has been burning for nearly two weeks.
Hurricane Milton, currently a Category 5 storm, is expected to make landfall this evening near Tampa, Florida, as a Category 4 hurricane with 130 mph winds, according to the National Weather Service. It will bring between 10 and 15 feet of storm surge (possibly more, depending on which forecast you’re following), plus tornadoes. The conditions have already started to deteriorate and will continue to do so throughout the day. “There is no recent precedent for a major hurricane to take this path toward Florida,” said AccuWeather Director of Forecasting Operations Dan DePodwin. “This is an increasing significant risk of devastating, catastrophic impacts to this region.”
AccuWeather
Climate change caused by the burning of fossil fuels almost certainly made Hurricane Milton and Hurricane Helene a lot worse, according to two new rapid attribution studies by World Weather Attribution and Climate Central. A storm like Hurricane Helene is about two-and-a-half times more likely in the region today compared to what would be expected in a “cooler pre-industrial climate,” WWA found. That means Helene, the kind of storm one would expect to see once every 130 years on average, is now expected to develop at a rate of about once every 53 years. Separately, Climate Central looked at Hurricane Milton, which already has the distinction of being the fifth strongest Atlantic storm on record. The nonprofit’s findings show that Milton’s rapid intensification — one of the fastest and most powerful instances of the phenomenon in history — is primarily due to high sea surface temperatures in the weeks before Milton developed, which was made at least 400 times more likely by climate change and up to 800 times more likely.
“While hurricane seasons eventually end, global temperatures haven’t stopped going up,” wrote Heatmap’s Jeva Lange. “That, perhaps, is the more terrifying subtext of the attribution studies: There will be more Miltons and Helenes.”
There are several big energy reports out this week, and taken together, their findings tell a nuanced story of an energy transition that’s well underway, but still moving too slowly. Let’s start with the big one: The International Energy Agency’s Renewables 2024 report, published this morning. It says that the world is on track to add 5,500 gigawatts of new clean energy capacity by 2030, 80% of which will come from solar PV alone. That means renewables will account for half of global electricity generation by the end of the decade.
IEA
While this is huge progress (the report notes that 5,500 GW is roughly equal the power capacity of China, the European Union, India, and the U.S. combined), it is not enough to meet the COP28 goal of tripling renewable capacity by 2030. But! The IEA stresses that it is “entirely possible” to meet this target if governments can get their acts together, set bold new emission reduction targets in the coming months, and work together to lower the energy transition costs for poorer countries. “The market can deliver on renewables, and now governments need to prioritize investing in storage, grids, and other forms of clean flexibility to enable this transformation,” said Dave Jones, director of global insights at energy think tank Ember. “The next half decade is going to be one heck of a ride.”
So, that’s renewables. Let’s look at what all this means for emissions and, most importantly, warming.
An energy transition report published this morning from Norwegian risk management company DNV concludes, rather remarkably, that energy-related emissions are set to peak this year and begin a steady decline thanks to the plummeting costs of solar and batteries, especially in China. “Emissions peaking is a milestone for humanity,” said Remi Eriksen, group president and CEO of DNV. However, the projected rate of emission reduction is only enough to limit warming to 2.2 degrees Celsius by 2100. “We must now focus on how quickly emissions decline and use the available tools to accelerate the energy transition,” Eriksen added.
The Rhodium Climate Outlook 2024 report, out yesterday, concluded that there is a less than 7% chance of the world limiting global warming to 2 degrees Celsius “if current trends in policy and technology development continue.” In fact, it projected a “very likely” increase between 2 degrees Celsius and *gulp* 3.7 degrees Celsius by century’s end. However, odds of limiting warming to 2 degrees jump to 96% if all countries can get to net-zero emissions by 2070. To date, 149 countries (representing 88% of global emissions) have made net-zero or carbon neutrality commitments, though it remains to be seen if and when they’ll meet those goals.

The cost of “green” hydrogen – that which is produced with clean energy – is likely to remain “prohibitively expensive,” according to a new study published yesterday in the journal Joule. The fuel is seen as key to curbing emissions from hard-to-abate sectors (industry, for example), and many are banking on the price of production falling. But the researchers say the high storage and distribution costs are often overlooked. Taking those costs into consideration, carbon capture and storage is cheaper than green hydrogen when it comes to curbing emissions, the researchers found. “Even if production costs decrease in line with predictions, storage and distribution costs will prevent hydrogen being cost-competitive in many sectors,” said lead author Roxana Shafiee, a postdoctoral fellow at the Harvard University Center for the Environment. “Our results challenge a growing idea that hydrogen will be the ‘Swiss army knife of decarbonization’ and suggest that the opportunities for hydrogen may be narrower than previously thought.”
“After 40 years in a career, hopefully, I get a little leeway from the folks who are accustomed to seeing me cool as a cucumber. But the truth is that with climate-driven extremes putting us in a place that we haven’t been before, it’s very difficult to stay cool, calm, and collected.” –Meteorologist John Morales on his emotional on-air reaction to Hurricane Milton’s rapid intensification.

On taxing renewables, climate finance, and Europe’s heat wave
Current conditions: Parts of Northern California are under red flag warnings as warm air meets whipping winds • China’s southwestern Guizhou province is flooded for the second time in a week • A potential bomb cyclone is taking aim at Australia’s east coast.
Late on Friday Senate Republicans added a new tax on solar and wind projects to the budget reconciliation megabill that sent many in the industry into full-blown crisis mode. The proposal would levy a first-of-its-kind penalty on all solar and wind projects tied to the quantity of materials they source from companies with ties to China or other countries designated as adversaries by the U.S. government. “Taken together with other factors both in the bill and not, including permitting timelines and Trump’s tariffs, this tax could indefinitely undermine renewables development in America,” wrote Heatmap’s Jael Holzman. Here are a few reactions from politicians and industry insiders:
The Senate began debating the GOP’s megabill yesterday. Republican Senator Thom Tillis of North Carolina was one of two from the majority party who voted on Saturday against debating the bill. Shortly thereafter, he announced he wouldn’t run for re-election next year after President Trump threatened to back his primary challenger. On Sunday evening, Tillis took to the Senate floor to give an impassioned speech denouncing the bill’s Medicaid cuts and defending wind and solar tax credits. The Senate will resume work on the bill today with what’s known as a “vote-a-rama,” during which senators will offer and vote on amendments that could yet introduce significant changes. A final vote from the Senate on the bill is expected sometime today.
The fourth International Conference on Financing for Development kicks off today in Spain, offering world leaders an opportunity to reform the world’s financial aid systems. The conference happens once per decade. This year’s delegates have already adopted the “Sevilla Commitment,” which commits to closing the $4 trillion financing gap for global goals such as ensuring everyone has affordable and reliable energy, making cities sustainable, and mobilizing $100 billion in climate mitigation funding each year toward developing countries. As Reuters explained, the text focuses on helping poor nations pay for adaptation through debt swaps, potential pollution taxes, and other creative funding mechanisms. More than 70 world leaders will be there, as will World Bank President Ajay Banga and representatives from the Gates Foundation. The U.S. government will not have a representative at the talks. The Trump administration withdrew after trying and failing to remove any mention of “climate” and “sustainability” from the conference’s draft text. Some sources told Reuters the event could be more successful without the U.S. there to “water down objectives.”
The European Union is considering changing its climate law to allow countries to lean on international carbon credits to reach emissions targets. The original goal was to cut direct emissions by 90% by 2040 compared to 1990 levels, but some countries have pushed back on that ambition, citing costs. A draft of the proposed change shows that the European Commission would allow high-quality carbon credits to account for 3% of the emissions cut starting in 2036. As Politico explains: “Such credits will allow the EU to pay for emissions-slashing projects in other, usually poorer countries, and count the resulting greenhouse gas reductions toward its own 2040 target, rather than the climate goals of the country hosting the project.” Accounting for 6% of global greenhouse gas emissions, the EU ranks fourth on the list of highest polluters, behind China, the U.S., and India.
Meanwhile, Europe is facing a punishing early-summer heat wave that is already smashing records and triggering weather alerts. A few numbers:
Nearly a third of the citizens of the Pacific island nation of Tuvalu have applied for the world’s first climate visa, which would allow them to permanently migrate to Australia.
As bad as previous drafts of the reconciliation bill have been, this one is worse.
Senate Republicans are in the final stages of passing their budget reconciliation megabill — which suddenly includes a new tax on solar and wind projects that has sent many in the industry into full-blown crisis mode.
The proposed tax was tucked inside the latest text of the Senate reconciliation bill, released late Friday night, and would levy a first-of-its-kind penalty on all solar and wind projects tied to the quantity of materials they source from companies with ties to China or other countries designated as adversaries by the U.S. government. Industry representatives are still processing the legislative language, but some fear it would kick in for certain developers as soon as the date of its enactment. Taken together with other factors both in the bill and not, including permitting timelines and Trump’s tariffs, this tax could indefinitely undermine renewables development in America.
On Saturday, as legislators began to digest the new text, Senator Brian Schatz declared on X not once, not twice, but three times that with the new penalty, this bill would on its own “kill” the U.S. solar energy industry, leading to energy shortages and raising costs across the board. "I promise you,” he wrote, “this bill is worse than you think.”
Senator Sheldon Whitehouse of Rhode Island, a staunch advocate for climate policy, said in a statement to Heatmap that the tax will help China and hurt American families, “all so Republican oil and gas donors can make even bigger profits. This isn’t policy; it’s pay-off.”
Without this new tax, energy companies might’ve quietly swallowed the bitter pill of losing the incentives established in the Inflation Reduction Act. In the weeks since the first version of this legislation was introduced in the House, I’ve interviewed numerous renewables developers, tax attorneys, and cleantech investors, who have emphasized the resilience of the industry given rising energy demand and explained that there would still be many ways for projects currently under development to qualify for the credits before they’d be phased out. The history of renewable energy tax credits in the U.S. is full of of phase-outs and restarts. The industry’s been at least somewhere like this before.
But the withdrawal of incentives is one thing. A targeted federal tax that could increase development costs by up to 20% that is levied over longstanding supply chain relationships that will take not years but rather decades to rebuild is another.
The American Council on Renewable Energy said in a statement that the latest iteration of the bill “effectively takes both wind and solar electric supply off the table, at a time when there is $300 billion of investments underway, and this generation is among the only source of electricity that will help to reduce costs and keep the lights on through the early 2030s.” The North America’s Building Trades Unions issued a statement after the text’s release calling it the “biggest job-killing bill in the history of this county” and adding that that “simply put, it is the equivalent of terminating more than 1,000 Keystone XL pipeline projects.”
“I think it’s impossible to overstate how this new version of the bill makes the House bill look moderate by comparison,” Andrew Reagan, president of Clean Energy 4 America, told me in an exasperated tone over the phone Saturday afternoon. “The hope as I see it is that as the full impact of how devastating this proposal would be for every state in the country comes into play, as this comes to the floor, Senate Republicans who claim to care about this issue come to [Majority Leader John] Thune and ask to amend this.”
The tax would apply to new solar and wind construction and be calculated based on the degree to which a project exceeds statutory limits for materials sourced from “foreign entities of concern,” i.e. Russia, North Korea, Iran, and most especially China. Solar projects would have to pay a 50% tax on the value of the overage, and wind projects would pay 30%.
Here’s a simplified example to illustrate how it would work: Say you are developing a solar project that will begin operating in 2028, and the total cost of all of your material inputs is $100,000. The new law would require that at least 50% of the value of all of your materials come from entities disconnected from Chinese companies and investment (the statutory limit for 2028), but your project is only able to achieve 40%. The extra $10,000 dollars you paid to companies with ties to China would be subject to the 50% solar tax, adding $5,000 to the total cost of your project. And this doesn’t even touch the new expense of capturing and reporting all of this supply chain data for the federal government.
The rules for how developers would actually calculate the value of their various material inputs will be subject to the Treasury’s interpretation and guidance, so it is impossible to determine how harshly this tax would fall on any individual solar or wind energy facility. Even so, Rhodium Group has estimated that it would increase project costs overall by 10% to 20% — a whopping total to eat on top of losing key tax credits.
This penalty for sourcing linked to China dates back to the IRA’s consumer electric vehicle tax credit. As I was first to report years ago for E&E News, Senator Joe Manchin successfully limited the credit’s scope by requiring qualifying cars to be made with an increasing percentage of materials from the U.S. or a country with a free trade agreement and mandating that materials could not come from a foreign entity of concern. This tactic mostly failed to reshore mineral supply chains as quickly Manchin had hoped it would, but it did ensure that relatively few vehicles qualified.
This anti-foreigner approach to energy policy has now been taken up by Republicans in Congress to erode the IRA overall. As my colleagues Emily Pontecorvo and Matthew Zeitlin have explained, the Senate legislation would deny tax credits to companies that have supply chains with any ties to China, which many say would effectively stop them from qualifying for the credits.
This specific policy approach is something I’ve previously dubbed the GOP’s “anti-China trap” for renewable energy. Now, on top of cutting off companies from tax credits, this trap will catch them for failing to reinvent their supply chains overnight with little if any warning. Of course, reshoring these supply chains will also be more difficult because of other provisions in the bill that would erode and eliminate advanced manufacturing tax incentives originally designed to encourage companies to make more of these components at home.
The only silver lining here is that the fight isn’t over. It wouldn’t surprise me to see a senator try to get rid of this tax as the bill moves through the amendment process on the Senate floor.
I expect some sort of intervention here because there appears to be momentum from powerful entities outside of Congress to get rid of this tax. Reviews of this piece of the bill are so bad, it has put the American Clean Power and the U.S. Chamber of Commerce on the same side as pro-fossil “philosopher” Alex Epstein, who is also calling on senators to oppose the tax.
“I just learned about the excise tax and it’s definitely not something I would support,” he posted to X yesterday, adding he’d rather they focus on removing the tax credits instead of creating a new cost. “I stand for energy freedom, always, in every situation,” he added in a separate post defending his opposition.
Elsewhere on X yesterday, Elon Musk spent hours (on his birthday, no less) going after the Senate bill, reposting energy wonks’ rants about the bill and its tax on renewables, including from Jesse Jenkins, the host of Heatmap’s very own Shift Key podcast.
So, okay, but will Musk, Epstein or any of these other critics convince at least one senator to force a successful vote on getting rid of the tax? That’s really the only way it can go away, because it’s very likely the Senate will force the House to pass whatever it passes.
I talked to Jenkins hours after Musk reposted him and filled up his replies. Like the iconoclastic billionaire, he told me he thinks this legislation is worse than anything congressional Republicans had released before it. A big reason for that is indeed the excise tax, a completely new idea that hadn’t been in any other previous draft of the bill or debated in committee, which he sees as a “obviously, deliberatively punitive attack on the wind and solar industry for what appears to be purely ideological reasons.”
“It’s going to kill hundreds of billions of dollars in investment and hundreds of gigawatts of new supply that would otherwise help us meet rapidly growing electricity demand. So, yeah, higher energy prices, less jobs, less investment in American energy production, and less confidence in the American business environment,” Jenkins said. “No one is asking for this.”
Debate on the bill is expected to begin later today, and the amendment process will stretch into Monday morning at least.
Additional reporting by Emily Pontecorvo
Editor’s note: This story has been updated to include a statement from Senator Sheldon Whitehouse.
A little-noticed provision would make the payment option used by tax-exempt groups all but impossible to claim.
A little-noticed provision in the Senate tax bill will sabotage the efforts of tribes, rural electric cooperatives, and public power authorities to develop local affordable energy projects by striking a section of the Inflation Reduction Act that enabled tax-exempt groups to claim the clean energy tax credits as direct cash payments from the Treasury.
The IRA included strict domestic sourcing requirements beginning in 2026 for groups utilizing this “direct pay” option on projects larger than 1 megawatt. But the law also created exceptions for cases where domestic components were not available in sufficient quantity or quality, or would increase costs by more than 25%. The Senate bill would get rid of these exceptions.
“It just makes it unlikely for those projects to go forward — or more likely for those projects to go forward with a private developer, instead of with a public utility or a tribe or a rural co-op,” Grace Henley, a tax attorney with the Natural Resources Defense Council, told me. “And so they don’t really do anything to increase the amount of domestic material that would be used, they just hurt the projects that are seeking to invest in clean energy infrastructure for these communities to lower costs.”
Public power and tribal energy advocates warn that without the exceptions, energy development will become impossible for their constituents.
Wind and solar projects being developed by these groups are already threatened by the bill’s rapid phase-out of wind and solar tax credits and its complex rules related to using materials from China. Chèri Smith, the executive director of the Alliance for Tribal Energy, told me that Tribes face longer development timelines than the average private developer. “We have multiple stages of approval that are unique to tribal energy development,” she told me, including lengthy internal consultation processes. The changes to direct pay will put these projects further out of reach, she said.
The Alliance provides free energy development consulting services to more than 100 Tribes. Smith sent me a list of projects in Alaska Native villages, Arizona, California, and Oregon that could be killed by the tax credit changes. “Alaska Native villages face some of the highest energy costs in the country,” she said, largely due to their reliance on diesel generators. Just over a third of the Hopi Tribe in Arizona lacks access to electricity, but now multiple microgrid projects meant to close the gap are at risk. Many of the projects on the list are also doubly threatened by grant cancellations and the repeal of the Tribal Energy Loan Guarantee Program.
“The bill is particularly harmful to Tribal Nations, pulling the rug out from under projects that would strengthen their energy sovereignty and power local communities,” Democratic Senators Martin Heinrich, Ron Wyden, and Brian Schatz wrote in a joint statement on Thursday. “Together, the Tribal Energy Loan Guarantee Program and our Inflation Reduction Act’s clean energy tax credits have cleared pathways and removed significant barriers for Tribes to finance and build their own resilient energy infrastructure.”
The American Public Power Association is also sounding the alarm. John Godfrey, the group’s senior government relations director, told me that in addition to wind and solar, municipal utilities and rural electric co-ops are also considering nuclear and hydropower projects. For example, Energy Northwest, a consortium of 29 public utilities in Washington State, has plans to retrofit the Columbia Generating Station nuclear plant to increase its power output. It’s also in early stages to deploy four small, modular nuclear reactors. As my colleague Matthew Zeitlin wrote a few days ago, the governor of New York has also tasked the New York Power Authority with developing a new nuclear plant in the state.
Nuclear and hydropower “are technologies where often there is not a U.S. source, but there is a good trading partner source — Canada, Germany, Japan,” Godfrey said. By tightening the domestic sourcing requirements for direct pay, the bill would “hinder the very technologies that there’s generally a bipartisan consensus we need to be developing.”
Public utilities and electric co-ops, which serve close to 30% of electric customers in the U.S., are also unfairly singled out by the provision, he said. “If my public power utility wants to develop a project and they need a Canadian turbine, they can’t get any credit. But if a taxable corporation down the street develops exactly the same project, they can.”
“If the purpose is to encourage hydropower, that’s not a good use of resources,” he said.
Editor’s note: This story has been updated to reflect that the domestic sourcing requirements in the IRA applied to projects larger than 1 megawatt.
