It’s been just over a week since one of the 350-foot-long blades of a wind turbine off the Massachusetts coast unexpectedly broke off, sending hunks of fiberglass and foam into the waters below. As of Wednesday morning, cleanup crews were still actively removing debris from the water and beaches and working to locate additional pieces of the blade.
The blade failure quickly became a crisis for residents of Nantucket, where debris soon began washing up on the island’s busy beaches. It is also a PR nightmare for the nascent U.S. offshore wind industry, which is already on the defensive against community opposition and rampant misinformation about its environmental risks and benefits.
The broken turbine is part of Vineyard Wind 1, which is being developed by Avangrid and Copenhagen Infrastructure Partners. The project was still under construction when the breakage occurred, but it was already the largest operating offshore wind farm in the US, with ten turbines sending power to the New England Grid as of June. The plan is to bring another 52 online, which will produce enough electricity to power more than 400,000 homes. Now both installation and power generation have been paused while federal investigators look into the incident.
There’s still a lot we don’t know about why this happened, what the health and safety risks are, and what it means for this promising clean energy solution going forward. But here’s everything we’ve learned so far.
What happened?
Vineyard Wind
On the evening of Saturday, July 13, Vineyard Wind received an alert that there was a problem with one of its turbines. The equipment contains a “delicate sensoring system,” CEO Klaus Moeller told the Nantucket Select Board during a public meeting last week. Though he did not describe what the alert said, he added that “one of the blades was broken and folded over.” Later at the meeting, a spokesperson for GE Vernova, which manufactured and installed the turbines, said that “blade vibrations” had been detected. About a third of the blade, or roughly 120 feet, fell into the water.
Two days later, Vineyard Wind contacted the town manager in Nantucket to explain that modeling showed the potential for debris from the blade to travel toward the island. Sure enough, fiberglass shards and other scraps began washing up on shore the next day, and all beaches on the island’s south shore were quickly closed to the public.
On Thursday morning, another large portion of the damaged blade detached and fell into the ocean. Monitoring and recovery crews continued to find debris throughout the area over the weekend. The beaches have since reopened, but visitors have been advised to wear shoes and leave their pets at home as cleanup continues.
Why did the blade break?
During GE’s second quarter earnings call on July 24, GE Vernova CEO Scott Strazik and Vice President of Investor Relations Michael Lapides said the company had identified a “material deviation” as the cause of the accident, and that the company is continuing to work on a "root cause analysis" to get to the bottom of how said deviation happened in the first place.
The turbine was one of GE’s Haliade-X 13-megawatt turbines, which are manufactured in Gaspé, Canada, and it was still undergoing post-installation testing by GE when the failure occurred — that is, it was not among those sending power to the New England grid. This was actually the second issue the company has had at this particular turbine site. One of the original blades destined for the site was damaged during the installation process, and the one that broke last week was a replacement, Craig Gilvard, Vineyard Wind’s communications director, told the New Bedford Light.
How did Vineyard Wind respond?
By Vineyard Wind’s account at the meeting last week, the accident triggered an automatic shut down of the system and activated the company’s emergency response plan, which
included immediately notifying the U.S. Coast Guard, the federal Bureau of Safety and Environmental Enforcement, and regional emergency response committees.
Moeller, the CEO, said during the meeting that the company worked with the Coast Guard to immediately establish a 500 meter “safety zone” around the turbine and to send out notices to mariners. According to the Coast Guard’s
notice log, however, the safety zone went into effect three days later. In response to my questions, the Coast Guard confirmed that the zone was established around 8pm that night and announced to mariners over radio broadcast.
Two days after the turbine broke, on Monday, Vineyard Wind contacted the National Oceanic and Atmospheric Administration for aid in modeling where the turbine debris would travel in the water. The agency
estimated pieces would likely make landfall in Nantucket that day. Vineyard Wind put out a press release about the accident and subsequently contacted the Nantucket town manager. At the Nantucket Select Board meeting last week, Moeller said the company followed regulatory protocols but that there was “really no excuse” for how long it took to inform the public, and said, “we want to move much quicker and make sure that we learn from this.”
The Interior Department’s Bureau of Safety and Environmental Enforcement has
ordered the company to cease all power production and installation activities until it can determine whether this was an isolated incident or affects other turbines.
By Tuesday, Vineyard Wind said it had deployed two small teams to Nantucket in addition to hiring a local contractor to remove debris on the island. The company later
said it would “increase its local team to more than 50 employees and contractors dedicated to beach clean-up and debris recovery efforts.”
GE Vernova is responsible for recovering offshore debris and has not published any public statements about the effort. In response to a list of questions, a GE Vernova spokesperson said, “We continue to work around the clock to enhance mitigation efforts in collaboration with Vineyard Wind and all relevant state, local and federal authorities. We are working with urgency to complete our root cause analysis of this event.”
Did anyone get hurt?
There have been no reported injuries as a result of the accident.
What are the risks now?
Vineyard Wind and GE Vernova have stressed that the debris are “not toxic.” At the Select Board meeting, GE’s executive fleet engineering director Renjith Viripullan said that the blade is made of fiberglass, foam, and balsa wood. It is bonded together using a “bond paste,” he said, and likened the blade construction to that of a boat. “That's the correlation we need to think about,” he said.
One of the board members asked if there was any risk of PFAS contamination as a result of the accident. Viripullan said he would need to “take that question back” and follow up with the answer later. (This was one of the questions I asked GE, but the company did not respond to it.)
That being said, the debris poses some dangers. Photos of cleanup crews posted to the Harbormaster’s Facebook page show workers wearing white hazmat suits. Vineyard Wind said “members of the public should avoid handling debris as the fiber-glass pieces can be sharp and lead to cuts if handled without proper gloves.”
Though members of the public raised concerns at the meeting and to the press that fiberglass fragments in the ocean threaten marine life and public health, it is not yet clear how serious the risks are, and several efforts are underway to further assess them. Vineyard Wind is developing a water quality testing plan for the island and setting up a process for people to file claims.GE hired a design and engineering firm to conduct an environmental assessment, which it will present at a Nantucket Select Board meeting later this week. The Massachusetts Department of Environmental Protection has requested information from the companies about the makeup of the debris to evaluate risks, and the Department of Fish and Game is monitoring for impacts to the local ecosystem.
How is the cleanup going?
As of last Wednesday morning, Vineyard Wind had collected “approximately 17 cubic yards of debris, enough to fill more than six truckloads, and several larger pieces that washed ashore.” It is not yet known what fraction of the turbine that fell off has been recovered. Vineyard Wind did not respond to a request for the latest numbers in time for publication, but I’ll update this piece if I get a response.
Has anything like this happened before?
Yes. In May, a blade on the same model of turbine, the GE Haliade-X, sustained damage at a wind farm being installed off the coast of England called Dogger Bank. At the Nantucket Select Board meeting, a spokesperson for GE said the Dogger Bank incident was “an installation issue specific to the installation of that blade” and that “we don’t think there’s a connection between that installation issue and what we saw here.” Executives emphasized this point during the earnings call and chalked up the Dogger Bank incident to “an installation error out at sea.”
Several blades have also broken off another GE turbine model dubbed the Cypress at wind farms in Germany and Sweden. After the most recent incident in Germany last October, the company used similar language, telling reporters that it was working to “determine the root cause.”
A “company source with knowledge of the investigations” into the various incidents recently told CNN that “there were different root causes for the damage, including transportation, handling, and manufacturing deviations.”
The backlash was swift. Nantucket residents immediately
wrote to Nantucket’s Select Board to ask the town to stop the construction of any additional offshore wind turbines. “I know it's not oil, but it's sharp and maybe toxic in other ways,” Select Board member Dawn Holgate told company executives at the meeting last week. “We're also facing an exponential risk if this were to continue because many more windmills are planned to be built out there and there's been a lot of concern about that throughout the community.”
The Select Board plans to
meet in private on Tuesday night to discuss “potential litigation by the town against Vineyard Wind relative to recovery costs.”
“We expect Vineyard Wind will be responsible for all costs and associated remediation efforts incurred by the town in response to the incident,” Elizabeth Gibson, the Nantucket town manager said during the meeting last week.
The Aquinnah Wampanoag tribe is
also calling for a moratorium on offshore wind development and raised concerns about the presence of fiberglass fragments in the water.
Meanwhile, environmental groups supportive of offshore wind tried to do damage control for the industry. “Now we must all work to ensure that the failure of a single turbine blade does not adversely impact the emergence of offshore wind as a critical solution for reducing dependence on fossil fuels and addressing the climate crisis,” the Sierra Club’s senior advisor for offshore wind, Nancy Pyne,
wrote in a statement. “Wind power is one of the safest forms of energy generation.”

Current conditions: After walloping Bermuda with winds of up to 100 miles per hour, Hurricane Imelda is veering northeast away from the United States • While downgraded from a hurricane, Humberto is set to soak Ireland and the United Kingdom as Storm Amy in the coming days and bring winds of up to 90 miles per hour • Typhoon Matmo is strengthening as it hits the Philippines and barrels toward China.
THE TOP FIVE
1. Energy Department kills West Coast hydrogen hubs
The Department of Energy is canceling two regional hydrogen hubs in California and the Pacific Northwest as part of a broader rescinding of 321 grants worth $7.5 billion for projects nationwide. Going after the hydrogen hubs, which the oil and gas industry lobbied to keep open after President Donald Trump came back to office, “leaves the agency’s intentions for the remaining five hubs scattered throughout the Midwest, Midatlantic, Appalachia, the Great Plains, and Texas unclear,” Heatmap’s Emily Pontecorvo wrote yesterday.
The list of canceled projects that Emily got her hands on “does seem to confirm that blue state grants were the hardest hit,” she wrote. But, she found, “many would actually have benefitted Republican strongholds,” including a $20 million grant for a manufacturing plant in Texas that was slated to create 200 jobs.
2. Tesla hits a sales record
Tesla’s global deliveries rose 7% in the third quarter, hitting a new record as Americans rushed to buy electric vehicles before the federal tax credit expired on September 30. The automaker delivered 497,099 vehicles in the three months leading up to that date, up from 462,890 in the same period last year, according to the Financial Times. That was well above analyst forecasts of 444,000.
That may do little to turn around the headwinds blasting the EV giant. While the company benefited from buyers scrambling to tap the federal EV tax credit, Tesla sank to its lowest-ever share of the electric vehicle market in August as drivers flocked to offerings from other automakers. It’s not just a problem in the U.S. As Heatmap’s Matthew Zeitlin wrote last month, “Thanks to CEO Elon Musk’s association with right wing politics in the U.S. and abroad, and to fierce competition from Chinese EV leader BYD, Tesla’s sales have fallen dramatically in Europe. Globally, BYD overtook Tesla in sales last year.”

3. The British Tories vow to repeal landmark climate law

Kemi Badenoch, the leader of the British Conservatives, has vowed to repeal the United Kingdom’s landmark climate law if her party, colloquially known as the Tories, wins the next election. Eliminating the Climate Change Act, passed almost unanimously under a Tory government in 2008, would dismantle controls on greenhouse gas emissions and remove what The Guardian described as “the cornerstone of green and energy policy for successive governments” for the past 17 years.
The move rankled past Tory leaders. Former Prime Minister Theresa May condemned the campaign pledge as a “catastrophic mistake.” Calling it a “retrograde” step, she said that “while consensus is being tested, the science remains the same.” Alok Sharma, the former Tory minister who led the COP26 climate summit in Glasgow in 2021, told The Guardian in a separate article that a repeal risked “many tens of billions of pounds of private sector investment and accompanying jobs.”
4. Antarctic sea ice shrinks to third-lowest winter peak
Sea ice in Antarctica reached its third-smallest winter peak extent since satellite records began 47 years ago, according to a new analysis by Carbon Brief. Provisional data from the U.S. National Snow and Ice Data Center showed Antarctic sea ice reaching a winter maximum of just under 6.9 million square miles as of September 17. That’s nearly 350,000 square miles below the average between 1981 and 2010, the historical baseline against which recent changes in sea ice extent are compared. The “lengthening trend of lower Antarctic sea ice poses real concerns regarding stability and melting of the ice sheet,” one expert told the publication.
The finding comes as a “groundbreaking” study the European Geosciences Union published Thursday in the journal Earth System Dynamics found that Antarctic sea ice has emerged as a key predictor of accelerated ocean warming. Using Earth system models and satellite images from 1980 to 2020, the researchers found higher sea ice extent enhances cloud cover, which has a cooling effect overall by reducing incoming solar radiation. As a result, ongoing sea ice loss is linked to larger reductions in clouds, stronger surface warming, and even more ocean heat uptake, accelerating the cycle.
5. Duke Energy extends coal use in new electricity plan
Duke Energy plans to meet surging demand for electricity by increasing its natural gas and battery capacity, keeping coal plants open for up to four years longer than previously estimated, and evaluating new sites for nuclear reactors. The 100-page biennial proposal published this week dials back plans for more renewables such as wind and solar. It also pushed back the earliest start date for a new reactor to 2037, declined to commit to either small modular reactors or large traditional units, and said the utility still needs extra protections against cost overruns before embarking on construction.
In the meantime, the added years of coal burning “will result in millions of tons in additional greenhouse gases over the next decade when combined with other proposed changes to the utility’s fuel mix,” Inside Climate News reported. In a statement to Axios, North Carolina Governor Josh Stein, a Democrat, called on the state’s utilities commission to “require significant changes” and condemned Duke for “retreating from the state’s clean energy future.”
THE KICKER
New research by a team of scientists from the U.K. and New Zealand has found that new analytical methods could bolster conservation breeding programs by offering a better understanding of why eggs don’t hatch. The researchers used fluorescent dyes to discover that nearly 66% of 174 unhatched eggs examined in the study had been fertilized, whereas previous methods suggested that only 5.2% had been fertilized. “There are many different factors that contribute to breeding success,” Gary Ward, a co-author from the London-based ZSL Institute of Zoology, said in a statement, “and the more understanding we can have into why an egg might not hatch, the more we can refine our care for these birds and the better chance of recovery we can give them.”
1. Ocean County, New Jersey – A Trump administration official said in a legal filing that the government is preparing to conduct a rulemaking that could restrict future offshore wind development and codify a view that could tie the hands of future presidential administrations.
In a court filing last Friday, Matthew Giacona – Trump’s principal deputy director of the Bureau of Ocean Energy Management – laid out the federal government’s thoughts about re-doing the entire review process that went into approving the Atlantic Shores project. The filing was related to the agency’s effort to stay a lawsuit brought by anti-wind advocates that officials say is unnecessary because, well … Atlantic Shores is already kind of dead.
But the Giacona declaration went beyond this specific project. He laid out how in the Trump administration’s view, the Biden administration improperly weighed the impacts of the offshore wind industry when considering the government’s responsibilities for governing use of the Outer Continental Shelf, which is the range of oceanfront off the coastline that qualifies as U.S. waters. Giacona cited an Interior Department legal memo issued earlier this year that revoked Biden officials’ understanding of those legal responsibilities and, instead, put forward an interpretation of the agency’s role that results in a higher bar for approving offshore wind projects.
Per Giacona, not only will BOEM be reviewing past approvals under this new legal opinion, but it will also try and take some sort of action changing its responsibilities under federal regulation for approving projects in the Outer Continental Shelf. Enshrining this sort of legal interpretation into BOEM’s regulations would in theory have lasting implications for the agency even after the Trump 2.0 comes to a close.
“BOEM is currently beginning preparations for a rulemaking that will amend that provision of the regulations, consistent with M-37086 [the legal opinion],” Giacona stated. He did not elaborate on the timetable for this regulatory effort in the filing.
2. Prince William County, Virginia – The large liberal city of Manassas rejected a battery project over fire fears, indicating that post-Moss Landing, anxieties continue to pervade in communities across the country.
The city was exploring whether to install five Tesla megapacks at an empty lot as a cost-saving and grid resilience maneuver. But the unanimous vote against battery storage came after testimony from fire officials about the risk a battery project could hypothetically pose to nearby residential areas.
Per media reports, city leaders are treating this as a true “not in my backyard” maneuver, hoping that denying this project leads it to be built somewhere else: Harrisonburg, a city in nearby Rockingham County, which is in an electrical co-op along with Manassas. Officials hope this still allows them to benefit from the system even if it isn’t built within city limits.
There’s no guarantees in sending the batteries to Harrisonburg, however. While Harrisonburg has welcomed battery storage and approved city land for a project in July, it is in Rockingham County, which in April rejected a battery storage project for similar fire anxieties, and is a region extremely likely to have opposition risk according to Heatmap Pro data.
3. Oklahoma County, Oklahoma – The Sooner state legislature on Monday held a joint committee meeting on solar and wind setbacks featuring prominent anti-wind advocates.
The meeting featured testimony from Saundra Traywick, one of the leading voices in the state calling for a total statewide ban on future large-scale wind and solar development. It also featured Lisa Linowes, head of Industrial Wind Action Group and director of the energy wing of the Michael Shellenberger-led organization Civilization Works. She also founded the Save Right Whales Coalition.
At the hearing, former Oklahoma attorney general John O’Connor urged the legislature to reject blanket restrictions on renewables development. Instead, he said to let municipalities and counties decide whether to host solar or wind power. A renewables industry attorney also testified at the meeting against Oklahoma doing “what Arkansas does,” a reference to that state’s new law creating siting requirements for the wind industry.
Predictably, other voices at the hearing – including Traywick and Linowes – encouraged a totally different approach. Anti-renewables advocates in the state at minimum do want broad setbacks required in every county and town. I believe this hearing means the start of a fresh fight, not the end.
4. Tippacanoe County, Indiana – The developers of a large-scale solar project are suing the county over being rejected.
The RWE-Geenex collaboration Rainbow Trout Solar was rejected by the Tippacanoe County Board of Zoning Appeals despite being recommended by permitting staff. This past week Rainbow Trout sued the board, arguing that the board’s split decision made by a single vote margin was made without a “rational basis.”
Historically litigation is seen by developers as a last resort because it is lengthy and aggravates tensions in potential host communities. As a result, it is unclear if this lawsuit will help Rainbow Trout meet its construction timelines, which anticipate operation in 2027.
5. Dane County, Wisconsin – The Wisconsin Public Service Commission approved Invenergy’s Badger Hollow wind project – the state’s first new fully-permitted wind energy project in more than a decade.
Badger Hollow, which was opposed by some residents in Iowa and Grant counties where it will be built, is set to consist of 19 turbines – a relatively small number, and fewer than what was initially proposed.
The PSC also approved Whitewater Solar, a large utility-scale project in southern Wisconsin I had predicted earlier this year would likely win out over a middling grassroots opposition on the ground.
Given that primacy laws where energy regulators have the power to supersede local opposition is a priority for pro-renewables advocates, it’s safe to call this intervention a small victory for permitting reform.
This week I chatted with Courtney Brady, Midwest region deputy director for climate advocacy group Evergreen Action. Brady recently helped put together a report on rural support for renewables development, for which Evergreen Action partnered with the Private Property Rights Institute, a right-leaning advocacy group. Together, these two organizations conducted a series of interviews with self-identifying conservatives in Pennsylvania and Michigan focused on how and why GOP-leaning communities may be hesitant, reluctant, or outright hostile to solar or wind power.
What they found, Brady told me, was that politics mattered a lot less than an individual’s information diet. The conversation was incredibly informative, so I felt like it was worth sharing with all of you.
The following chat was edited lightly for clarity. Let’s dive in:
Okay, so tell me first why you did this report.
Clean energy deployment is getting increasingly challenging for a variety of reasons. What’s happening on the federal level is one thing, but something we don’t talk about much in the climate movement is what’s happening locally, what actually determines the odds of a project being successful and incorporated into the grid.
The side of the story we often hear that’s the loudest is from people at the local level who are opposed to these projects, and it limits our ability to understand the nuances. It’s not always that everyone opposes these projects in their community — that’s often not the case. We talked to several farmers in this report who are using these projects as a lifeline to keep farms in their families’ hands, generate income, preserve their farms. These projects can provide an income lifeline for these farms.
Something we tried to accomplish with this report was to understand the different perspectives, what was driving them. The only way we could do that was by going out and talking to these people in their own communities, on their own land.
The group we worked with has a very conservative background. They work on Republican campaigns. They’re very involved in local government relations. And they were the ones who were able to go out and interview these folks about what this means for their communities.
A few weeks ago, I interviewed the head of the League of Conservation Voters about the way that renewables are perceived as culturally left wing. Are there any takeaways in your research about how to deal with that?
You know, I expected to hear a little bit more of that political ideological leanings than what we actually got in these interviews. Our partners went out and interviewed seven folks; four of the case studies were in Pennsylvania, and three of them were in Michigan. It was a mix of local government officials and landowners themselves, most of whom were farmers. And they asked them, What are you hearing in your community? Where’s the opposition coming from?
I’d assumed this would be a left-versus-right, red-versus-blue issue, but this is not what we heard. We heard a lot about a lack of information or misinformation in these communities and the crucial incomes these projects can provide to landowners themselves. Again, everyone in this report that was interviewed identified as a conservative or said they were Trump supporters. It’s interesting to hear that hasn’t impacted their views of clean energy at large. They were either really happy with the projects they’d sited or still trying to get projects sited years and years later.
When you talked about misinformation, what came up?
The sizing of these leases. We heard about fears in communities that land was going to be completely overtaken over by solar or wind.
Some of these farmers said one of the biggest things they heard from their neighbors was that we’re giving away hundreds and thousands of acres to solar projects and wind projects and taking away land that should go towards crops and food. We’re hearing from these farmers that a lot of this land is no longer fertile, so providing a temporary solar lease allows that farmer to continue generating revenue while letting that land breathe.
People really had this fear of farmland being completely converted to energy production. I don’t know where a lot of that came from. We asked if that was something spread on the internet and we heard, Neighbors talk and there are Facebook groups. So there’s this overblown fear about the size of projects.
When it comes to these interviews, it does seem like you spoke to a lot of people who believe what you say. But did you speak to people who don’t believe this stuff? Because right now we’re seeing cases where opposition is either winning over county commissioners or voting out of office local officials who believe exactly what you heard from some folks.
We’ve heard so much of the opposition. It’s trending, really growing across the country. And understanding the root of why opposition is there is important. But so often we don’t hear the other side of it, these really nuanced perspectives.
There are these folks in the middle who are really thematic in these interviews — this is not about energy but a core American property rights issue. That resonates with people regardless of party.
The other piece is, there’s fear in communities of being the person to speak out against groups that are loud, the ones who want to kick people out of office over energy things. So it was really important to elevate these voices and in the interviews just made a lot of common sense. This was about elevating voices that don’t always get a seat at the table in discussions around these issues.
