These can really do it all — almost.

Before and for the first year or so after the Inflation Reduction Act, clean energy in the United States was largely developed under the aegis of two tax credits: the Production Tax Credit, which primarily useful for wind power, and the Investment Tax Credit, which is primarily used for solar power. (The actual eligibility for each tax credit for each technology has changed various times over the years, but that’s the gist.)
Starting in 2025, however, and lasting (absent any change in the law) through at least 2032, that tax credit regime will be made “technology neutral.” Goodbye, existing credits with their limited applicability. Hello, new tax credits that apply to “any clean energy facility that achieves net-zero greenhouse gas emissions,” according to a release issued Wednesday by the Treasury Department.
“For too long, the U.S. solar and wind markets have been hampered by uncertainty due to the on-again-off-again nature of key tax credits,” Treasury Secretary Janet Yellen said on a call with reporters. “Periods of indecision and the credits being repeatedly allowed to elect to lapse made it too difficult for companies to plan and invest in clean energy projects.”
About that “at least”: The tax credits only start to phase out when Treasury determines that electricity-related greenhouse gas emissions have been reduced 75% from their 2022 levels or in 2032, whichever comes later, making this the rare tax code provision with an outcome-based timeline.
In preparation for the new Clean Electricity Production Credit and Clean Electricity Investment Credit, a.k.a. sections 45Y and 48E of the U.S. tax code, to go into effect, Treasury proposed guidance outlining what would qualify for the tax credits and soliciting comments on forms of power generation whose true carbon abatement potentials are more in doubt. The notice and subsequent publication in the Federal Register kicks off a 60-day public comment period, after which Treasury and the Internal Revenue Service will write the final rules.
The new list of eligible technologies includes “hydropower, marine and hydrokinetic, nuclear fission and fusion, geothermal,” along with “certain types of waste energy recovery property” as among the technologies that will be “categorically” eligible for the new tax credits. The point here isn’t to create more exclusivity, but rather to “provide clarity and certainty to developers,” Treasury said in the release. Yellen added that, “for the first time, these incentives are tied explicitly to electricity generation with zero emissions instead of specific technologies.”
What this announcement does not clarify, however, is what to do about energy sources that involve combustion, such as biomass or harnessing methane emitted from landfills. Here is where the Treasury Department is asking for help from outside — many of the questions included in the proposed rulemaking are devoted to figuring out exactly how these forms of energy might or might not be made zero-emission.
Many environmental groups are skeptical of any combustion-based energy sources, and Treasury said that generation methods which “rely on combustion or gasification to produce electricity” will have to “undergo a lifecycle greenhouse gas analysis to demonstrate net-zero emissions.”

The storm currently battering Jamaica is the third Category 5 to form in the Atlantic Ocean this year, matching the previous record.
As Hurricane Melissa cuts its slow, deadly path across Jamaica on its way to Cuba, meteorologists have been left to marvel and puzzle over its “rapid intensification” — from around 70 miles per hour winds on Sunday to 185 on Tuesday, from tropical storm to Category 5 hurricane in just a few days, from Category 2 occurring in less than 24 hours.
The storm is “one of the most powerful hurricane landfalls on record in the Atlantic basin,” the National Weather Service said Tuesday afternoon. Though the NWS expected “continued weakening” as the storm crossed Jamaica, “Melissa is expected to reach southeastern Cuba as an extremely dangerous major hurricane, and it will still be a strong hurricane when it moves across the southeastern Bahamas.”
So how did the storm get so strong, so fast? One reason may be the exceptionally warm Caribbean and Atlantic.
“The part of the Atlantic where Hurricane Melissa is churning is like a boiler that has been left on for too long. The ocean waters are around 30 degrees Celsius, 2 to 3 degrees above normal, and the warmth runs deep,” University of Redding research scientist Akshay Deoras said in a public statement. (Those exceedingly warm temperatures are “up to 700 times more likely due to human-caused climate change,” the climate communication group Climate Central said in a press release.)
Based on Intergovernmental Panel on Climate Change reports, the National Oceanic and Atmospheric Administration concluded in 2024 that “tropical cyclone intensities globally are projected to increase” due to anthropogenic climate change, and that “rapid intensification is also projected to increase.”
NOAA also noted that research suggested “an observed increase in the probability of rapid intensification” for tropical cyclones from 1982 to 2017 The review was still circumspect, however, labeling “increased intensities” and “rapid intensification” as “examples of possible emerging human influences.”
What is well known is that hurricanes require warm water to form — at least 80 degrees Fahrenheit, according to NOAA. “As long as the base of this weather system remains over warm water and its top is not sheared apart by high-altitude winds, it will strengthen and grow.”
A 2023 paper by hurricane researcher Andra Garner argued that between 1971 and 2020, rates of intensification of Atlantic tropical storms “have already changed as anthropogenic greenhouse gas emissions have warmed the planet and oceans,” and specifically that the number of these storms that intensify from Category 1 or weaker “into a major hurricane” — as Melissa did so quickly — “has more than doubled in the modern era relative to the historical era.”
“Hurricane Melissa has been astonishing to watch — even as someone who studies how these storms are impacted by a warming climate, and as someone who knows that this kind of dangerous storm is likely to become more common as we warm the planet,” Garner told me by email. She likened the warm ocean waters to “an extra shot of caffeine in your morning coffee — it’s not only enough to get the storm going, it’s an extra boost that can really super-charge the storm.”
This year has been an outlier for the Atlantic with three Category 5 storms, University of Miami senior research associate Brian McNoldy wrote on his blog. “For only the second time in recorded history, an Atlantic season has produced three Category 5 hurricanes,” with wind speeds reaching and exceeding 157 miles per hour, he wrote. “The previous year was 2005. This puts 2025 in an elite class of hurricane seasons. It also means that nearly 7% of all known Category 5 hurricanes have occurred just in this year.” One of those Category 5 storms in 2005 was Hurricane Katrina.
Jamaican emergency response officials said that thousands of people were already in shelters amidst storm surge, flooding, power outages, and landslides. Even as the center of the storm passed over Jamaica Tuesday evening, the National Weather Service warned that “damaging winds, catastrophic flash flooding and life-threatening storm surge continues in Jamaica.”
Fullmark Energy quietly shuttered Swiftsure, a planned 650-megawatt energy storage system on Staten Island.
The biggest battery project in New York has been canceled in a major victory for the nascent nationwide grassroots movement against energy storage development.
It’s still a mystery why exactly the developer of Staten Island’s Swiftsure project, Fullmark Energy (formerly known as Hecate), pulled the plug. We do know a few key details: First, Fullmark did not announce publicly that it was killing the project, instead quietly submitting a short, one-page withdrawal letter to the New York State Department of Public Service. That letter, which is publicly available, is dated August 18 of this year, meaning that the move formally occurred two months ago. Still, nobody in Staten Island seems to have known until late Friday afternoon when local publication SI Advance first reported the withdrawal.
Second, Swiftsure was going to be massive. It was the largest planned battery storage project in New York State, according to public records, with the ability to store upwards of 650 megawatts of electricity — enough to power more than half a million homes. That makes Swiftsure likely one of the largest battery projects in the country, with more capacity than any other energy storage project currently facing opposition in the U.S., according to our very own Heatmap Pro database. This is the second Fullmark project to totally flop in recent months. We reported last week that one of the company’s projects outside of Los Angeles had its permits voided in a court ruling that also blocked battery storage development in unincorporated areas outside the city.
Third, and potentially most significant for energy developers in New York City: Swiftsure’s death will almost certainly embolden the anti-storage activist movement.
Curtis Sliwa, the Republican nominee in next week’s New York mayoral election, was one of many local politicians who opposed Swiftsure and rallied with residents close to the proposed site in May. He’s part of a broader trend of Republican politicians becoming skeptical of battery storage sites near where people live and work, including in Democrat-ruled New York.
Putting batteries in the five boroughs has always been a challenge, but January’s Moss Landing battery fire in California created a PR frenzy in the city, as conservative figures seized on the online panic created by the blaze. Once-agnostic GOP members of Congress from New York City are now anti-battery storage in their backyards, including Anthony D’Esposito, Nicole Malliotakis and Mike Lawler. Trump’s Environmental Protection Agency administrator, Lee Zeldin — a former NYC congressman — is now weighing in against individual battery projects on Long Island and Staten Island.
Swiftsure was proposed in 2023 and permitted by the state last year. Fullmark was given a deadline of this spring to submit routine paperwork demonstrating how it would comply with conditions of the site’s permit, including how the battery storage project would be decommissioned. In August, the New York Department of Public Service gave Fullmark an extension until October 11.
Instead of meeting that October deadline, it seems Fullmark quietly withdrew its Swiftsure proposal.
It’s unclear how Democrat Zohran Mamdani or independent Andrew Cuomo would handle the rise of the anti-battery movement if either of them wins the November 4 mayoral election. That’s partially because energy policy and climate change have been non-issues in the campaign, saving small mentions of nuclear power, heat pumps, or gas prices in one-off debate answers or social media posts.
Sliwa, who has referred to Swiftsure as a “mini Chernobyl,” told me that he anticipates this victory will lead to more protests at more battery sites, no matter who wins the mayoral election. “The cancellation of this lithium-ion battery warehouse will reverberate throughout the boroughs,” Sliwa told me Monday. “It’ll be a rallying cry [because] it’s not a fait accompli that these facilities will be complete and operational.”
The Mamdani and Cuomo campaigns did not respond to requests for comment on Swiftsure’s cancellation.
The lost federal grants represent about half the organization’s budget.
The Interstate Renewable Energy Council, a decades-old nonprofit that provides technical expertise to cities across the country building out renewable clean energy projects, issued a dramatic plea for private donations in order to stay afloat after it says federal funding was suddenly slashed by the Trump administration.
IREC’s executive director Chris Nichols said in an email to all of the organization’s supporters that it has “already been forced to lay off many of our high-performing staff members” after millions of federal dollars to three of its programs were eliminated in the Trump administration’s shutdown-related funding cuts last week. Nichols said the administration nixed the funding simply because the nonprofit’s corporation was registered in New York, and without regard for IREC’s work with countless cities and towns in Republican-led states. (Look no further than this map of local governments who receive the program’s zero-cost solar siting policy assistance to see just how politically diverse the recipients are.)
“Urgent: IREC Needs You Now,” begins Nichols’ email, which was also posted to the organization’s website in full. “I need to be blunt: IREC, our mission, and the clean energy progress we lead is under assault.”
In an interview this afternoon, Nichols told me the DOE funding added up to at least $8 million and was set to be doled out over multiple years. She said the organization laid off eight employees — roughly a third of the organization’s small staff of fewer than two-dozen people — because the money lost for this year represented about half of IREC’s budget. She said this came after the organization also lost more than $4 million in competitive grant funding for apprenticeship training from the Labor Department because the work “didn’t align with the administration’s priorities.”
Nichols said the renewable energy sector was losing the crucial “glue” that holds a lot of the energy transition together in the funding cuts. “I’m worried about the next generation,” she told me. “Electricity is going to be the new housing [shortage].”
IREC has been a leading resource for the entire solar and transmission industry since 1982, providing training assistance and independent analysis of the sector’s performance, and develops stuff like model interconnection standards and best practices for permitting energy storage deployment best practices. The organization boasts having worked on developing renewable energy and training local workforces in more than 35 states. In 2021, it absorbed another nonprofit, The Solar Foundation, which has put together the widely used annual Solar Jobs Census since 2010.
In other words, this isn’t something new facing a potentially fatal funding crisis — this is the sort of bedrock institutional know-how that will take a long time to rebuild should it disappear.
To be sure, IREC’s work has received some private financing — as demonstrated by its solar-centric sponsorships page — but it has also relied on funding from Energy Department grants, some of which were identified by congressional Democrats as included in DOE’s slash spree last week. In addition, IREC has previously received funding from the Labor Department and National Labs, the status of which is now unclear.
