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.

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.
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.
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.”
There have been no reported injuries as a result of the accident.
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.
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.
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.”
GE Vernova’s stock price fell nearly 10% last Wednesday.
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.
On social media, anti-wind groups throughout the northeast took up the story as evidence that offshore wind is “not green, not clean.” Republican state representatives in Massachusetts cited the incident as a reason for opposing legislation to expedite clean energy permitting last week. Fox News sought comment from internet personality and founder of Barstool Sports David Portnoy, who owns a home on Nantucket and said the island had been “ruined by negligence.” The Texas Public Policy Foundation, a nonprofit funded by oil companies and which is backing a lawsuit against Vineyard Wind, cited the incident as evidence that the project is harming local fishermen. The First Circuit Court of Appeals is set to hear oral arguments on the case this Thursday.
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.”

Rob talks New Jersey past, present, and future with Employ America’s Skanda Amarnath.
Electricity prices are the biggest economic issue in the New Jersey governor’s race, which is perhaps next month’s most closely watched election. Mikie Sherrill, the Democratic candidate and frontrunner, has pledged to freeze power prices for state residents after getting elected. Can she do that?
On this week’s episode of Shift Key, Rob talks to Skanda Amarnath, the executive director of Employ America, a center-left think tank that aims to encourage a “full-employment, robust-growth economy.” He’s also a nearly lifelong NJ resident. They chat about how New Jersey got such expensive electricity, whether the nuclear construction boom is real, and what lessons nuclear companies should take from economic history.
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. Jesse is off this week.

Here is an excerpt from our conversation:
Robinson Meyer: Is there a nuclear bubble? … As people who are interested in long-term decarbonization, number one, this is quite reminiscent of the environment that hit clean energy companies right as Biden was taking office. And number two, is there a nuclear bubble, and what does this mean for how we should think about nuclear going forward? Because at the end of this, I think the only way that any of this helps the climate is if we build a lot more plants.
Skanda Amarnath: We are definitely in a moment when there’s a lot of froth. I don’t want to say everything — it’s always like, it’ll feel unfair and not accurate to go after every single proposition that’s in markets. Like for example, Rick Perry’s Fermi America, they did an IPO and raised a lot of capital pretty successfully. And they have a plan for how they want to build a lot of stuff out — gas, solar, batteries. They want to build four AP1000s, the large, light-water reactors that are seen as the most recent that we’ve built in the United States, and they think they could do them at the same speed that China builds those same reactors.
On the surface of it, there are parts of it that seem interesting and promising. On the other hand, there’s also parts of it that feel very much wrapped up in the speculative frenzy. It gets more exaggerated when you get to like examples like Oklo. They seem to be very politically connected, specifically to Chris Wright. That plus some very small milestone successes in the fuel supply chain are now being sort of magnified into, They’re going be very successful in building out there first of a kind technology. And even in the space of small modular reactors, what they’re offering seems at least substantially more risky than what may be — outside of the space, so even compared to GE’s proposition for a small boiling water reactor, the technology that’s involved with like Oklo is kind of out there.
And one of the things, the lessons of nuclear, if you look through the history, is the more new stuff you’re doing, the harder it is, the more likely it is that you will get heartburn in terms of cost, in terms of schedule, and you never want to do this again. And it’ll involve a lot of bankruptcy, as it did with the case of the Georgia reactors that were built in the last decade. And so this is a sign that there’s clearly a lot of hype and a lot of willingness to take risk, and it’s not really backed up by fundamentals. That can be sometimes overrated in a boom. But that is something that people will look to in a bust and say, what were we doing here? Why was the price of the stock so high?

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.”
With Trump turning the might of the federal government against the decarbonization economy, these investors are getting ready to consolidate — and, hopefully, profit.
Since Trump’s inauguration, investors have been quick to remind me that some of the world’s strongest, most resilient companies have emerged from periods of uncertainty, taking shape and cementing their market position amid profound economic upheaval.
On the one hand, this can sound like folks grasping at optimism during a time when Washington is taking a hammer to both clean energy policies and valuable sources of government funding. But on the other hand — well, it’s true. Google emerged from the dot-com crash with its market lead solidified, Airbnb launched amid the global financial crisis, and Sunrun rose to dominance after the first clean tech bubble burst.
The circumstances may change, but behind all of these against-the-odds successes are investors who saw opportunity where others saw risk. In the climate tech landscape of 2025, well-capitalized investors are eyeing some of the more mature sectors being battered by federal policy or market uncertainty — think solar, wind, biogas, and electric transportation — rather than the fresh-faced startups pursuing more cutting edge tech.
“History does not repeat, but it certainly rhymes,” Andrew Beebe, managing director at Obvious Ventures, told me. He was working as the chief commercial officer at the solar company Suntech Power when the first climate tech bubble collapsed in the wake of the 2008 financial crisis. Back then, venture capital and project financing dried up instantly, as banks and investors faced heavy losses from their exposure to risky assets. This time around, “there’s plenty of capital at all stages of venture,” as well as infrastructure investing, he said. That means firms can afford to swoop in to finance or acquire undervalued startups and established companies alike.
“I think you’re gonna see a lot of projects in development change hands,” Beebe told me.
Investors don’t generally publicize when the companies or projects that they’re backing become “distressed assets,” i.e. are in financial trouble, nor do they broadcast when their explicit goal is to turn said projects around. But that’s often what opportunistic investing entails.
“As investors in the energy and infrastructure space — which is inherently in transition — we take it as a very important point of our strategy to be opportunistic,” Giulia Siccardo, a managing director at Quinbrook, told me. (Prior to joining the investment firm, Siccardo was director of the Department of Energy’s Office of Manufacturing & Energy Supply Chains under President Biden.)
Quinbrook sees opportunities in biogas and renewable natural gas, a sector that once enjoyed “very cushioned margins” thanks to investor interest in corporate sustainability, Siccardo told me, but which has lately gone into a “rapid decline.” But she’s also looking at solar and storage, where developers are rushing to build projects before tax credits expire, as well as grid and transmission infrastructure, given the dire need for upgrades and buildout as load growth increases.
As of now, the only investment Quinbrook has explicitly described as opportunistic is its acquisition of a biomethane facility in Junction City, Oregon. When it opened in 2013, the facility used food waste — which otherwise would have emitted methane in a landfill — to produce renewable biogas for clean electricity generation. But after Shell acquired the plant, it switched to converting cow manure and agricultural residue into renewable natural gas for heavy-duty transportation fuels, a process that it’s operated commercially since 2021. Siccardo declined to provide information about the plant’s performance at the time of Quinbrook’s acquisition, though presumably, it has yet to reach its total production capacity of 730,000 million British thermal units per year — enough to supply about 12,000 U.S. households.
The extension of the clean fuel production tax credit, plus the potential for hyperscalers to purchase RNG credits, are still driving demand, however. And that’s increased Siccardo’s confidence in pursuing investments and acquisitions in the space. “That’s a market that, from a policy standpoint, has actually been pretty stable — and you might even say favored — by the One Big Beautiful Bill relative to other technologies,” she explained.
Solar, meanwhile, is still cheap and quick to deploy, with or without the tax credits, Siccardo told me. “If you strip away all subsidies, and are just looking at, what is the technology that’s delivering the lowest cost electron, and which technology has the least supply chain bottlenecks right now in North America —- that drives you to solar and storage,” she said.
Another leading infrastructure investment firm, Generate Capital, is also looking to cash in on the moment. After replacing its CEO and enacting company-wide layoffs, Generate’s head of external affairs, Jonah Goldman, told me that “managers who understand the [climate] space and who can take advantage of the opportunities that are underpriced in this tougher market environment are set up to succeed.”
The firm also sees major opportunities when it comes to good old solar and storage projects. In an open letter, Generate’s new CEO, David Crane, wrote that “for the first time in nearly four decades, the U.S. has an insatiable need for more power: as much as we can produce, as soon as we can, wherever and however we can produce it.”
Crane sees it as the duty of Generate and other investors to use mergers and acquisitions as a tool to help clean tech scale and mature. “If companies across our subsectors were publicly traded, the market itself would act as a centripetal force towards industry consolidation,” he wrote. But because many clean energy companies are privately funded, Crane said “it is up to us, the providers of that private capital, to force industry improvement, through consolidation and otherwise.”
Helping solar companies accelerate their construction timelines to lock in tax credit eligibility has actually become an opportunistic market of its own, Chris Creed, a managing partner at Galvanize Climate Solutions and co-head of its credit division, told me. “Helping those companies that need to start or complete their projects within a predetermined time frame because of changes in the tax credit framework became an investable opportunity for us,” Creed told me. “We have a number of deals in our near term pipeline that basically came about as a result of that.”
Given that some solar companies are bound to fare better than others, he agreed that mergers and acquisitions were likely — among competitors as well as involving companies working in different stages of a supply chain. “It wouldn’t shock me if you saw some horizontal consolidation or some vertical integration,” Creed told me.
Consolidation can only go so far, though. So while investors seem to agree that solar, storage, and even the administration’s nemesis — wind — are positioned for a long and fruitful future, when it comes to more emergent technologies, not all will survive the headwinds. Beebe thinks there’s been “irrational exuberance” around both green hydrogen and direct air capture, for example, and that seasoned investors will give those spaces a pass.
Electric mobility — e.g. EVs, electric planes, and even electrified shipping — and grid scalability — which includes upgrades to make the grid more efficient, flexible, and optimized — are two sectors that Beebe is betting will survive the turmoil.
But for all investors that have the capability to do so, for now, “the easy bet is just to move your money outside the U.S.” Beebe told me.
We might be starting to see just that. Quinbrook also invests in the U.K. and Australia, and just announced its first Canadian investment last week. It acquired an ownership stake in Elemental Clean Fuels, an energy developer making renewable fuels such as RNG, low-carbon methanol, and — yes — clean hydrogen.
Last week, Generate announced that it had closed $43 million in funding from the Canadian company Fiera Infrastructure Private Debt for its North American portfolio of anaerobic digestion projects, which produce renewable natural gas — Generate’s first cross-currency, cross-border deal.
Creed still has confidence in the U.S. market, however, telling me he’s “very bullish on American innovation.” He certainly acknowledges that it’s a tough time out there for any investor deciding where to park their money, but thinks that ultimately, “that volatility should manifest itself as excess returns to investors who are able to figure out their investment strategy and deploy in this environment.”
Exactly what firms will manage this remains an open question, and the opportunities may be short-lived — but it’s a race that plenty of investors are getting in on.
