Let's dive deep into the campaign against the so-called “high-risk” cables.

One of the biggest threats to American offshore wind is a handful of homeowners on the south Jersey shoreline spouting unproven theories about magnetic fields.
Within a year of forming, the activist group “Stop The High-Risk Cables” has galvanized local politicians against the transmission infrastructure being planned for wind turbines off the coast of New Jersey known as the Larrabee Pre-built Infrastructure. The transmission route, which will run a few miles from the beaches of Sea Girt, New Jersey, to a substation nearby, is expected to be a crucial landing zone for power from major offshore wind projects in south Jersey waters, including Atlantic Shores, a joint venture between EDF Renewables and Shell that received final permits from federal regulators last week.
The only problem: while state regulators have been busy planning the route for the transmission and selecting who will build it, opponents have managed to win the war of public opinion. Activists have clearly turned their neighbors against the plan, pushing the mayors of the four boroughs targeted for Pre-Built Infrastructure to come out against the project. And this weekend Jack Ciattarelli – who narrowly lost the race for the governor’s mansion last year and is running again in 2025 – joined activists rallying against the project and is now campaigning on ending the project and cable landings like it.
Since federal regulators control the waters, what this means is, unless Democrats hit the electoral jackpot over the next year, offshore wind in New Jersey could be screwed – even if Kamala Harris wins the White House.
What makes this more dire is, this isn’t any ol’ transmission. For other offshore wind projects like Empire Wind, states have forced developers to design and construct their own transmission landings, creating a somewhat disorganized situation resembling electrical spaghetti. New Jersey’s offshore wind transmission meanwhile has been studied for years and is supposed to minimize development on the shoreline. This means the combat over this cabling could decide the fates of multiple offshore wind projects – and the first major proactive plan to reduce beach-level environmental impacts that stymie offshore wind in the first place.
So I decided to dive deep into the campaign against the so-called “high-risk” cables. After a series of interviews with organizers and a mayor critical of the state’s processes, I’ve been left feeling this relatively small transmission project represents a true test for democracy’s role in climate action. Could a small band of organized individuals be all it takes to hold back decarbonization at the pace scientists say is necessary, no matter how many climate laws are passed?
Sea Girt resident Kimberly Paterson remembers when she first heard about the cables. Someone had left a postcard on her door about the project. Before that, the professional executive leadership trainer had devoted her activism to preserving maritime forests on the beach. Once made aware of the transmission cables though, she and her small coterie of environmentally-conscious neighbors got active.
Paterson said they also started getting looped in with an existing network of activists concerned about offshore wind infrastructure. Those activists included familiar characters to the fight over New Jersey offshore wind development.
People like Mike Dean of Save the East Coast and Cindy Zipf of Clean Ocean Action, who’ve spread theories without evidence about a spate of whale deaths being tied to pile drivers for offshore wind. She says her group’s work is focused on the cables, not offshore wind, despite the close allyship with these other actors. As she simply put it, “There’s a circle of people that you meet.”
“We do like to work with others, and communicate with others, but we’re not officially tied to any of those other groups.”
The group also started canvassing, making signage for homeowners, and holding public events. As calls for action grew, so too did the political focus on the area, as state legislators and members of Congress took up the issue.
“We have created an absolute firestorm here,” Paterson told me. ‘It is unbelievable what we’ve accomplished.”
The group is focused on what they believe to be the health risks of simply being near high-voltage power lines.
To understand their fears, think of an electric current going through a wire. The more current goes through a wire, the higher likelihood of electrical waves emanating from the current’s pathway. That’s where “electro-magnetic fields” come into play. These fields are all around us and even Earth emits them. It’s the result of an excess of energy.
The World Health Organization classifies even low amounts of electromagnetic fields as a possible carcinogen, citing studies around exposure and childhood leukemia rates. But as many environmental and health experts note, studies to date have not really linked cancer occurrences to prolonged exposure to these fields. The Bureau of Ocean Energy Management says the electro-magnetic fields created by cables for offshore wind “are well below the recommended threshold values for human exposure.” So like whales and wind, it’s something to watch out for, but there’s no evidence to date of a danger here.
Nonetheless, seeking to calm any resident’s fears of magnetic fields, the New Jersey Board of Public Utilities last week convened their first public hearing within the planned development area.
At the event, numerous officials came and spoke to the project’s safety, including the executive director of the Board. They even played a long explanatory video from a consultant they hired to review the electro-magnetic fields that would come from the cables. The full presentation laid out numerous examples of what they said were similar underground and underwater transmission lines with magnetic emissions that had no discernable impact on public health, including lines in the New Jersey-New York region.
One person moved by the presentation’s efforts on magnetic fields was Mike Mangan, mayor of Manasquan, one of the boroughs that may be selected to host some of the transmission infrastructure. Mangan told me he joined with other mayors to press the state for more transparency on the cables at the behest of concerned constituents. But he didn’t know what the state knew about the magnetic fields.
“I’ll just be candid — I was ignorant on a lot of that,” he acknowledged. Mangan said he still has “a few very serious concerns” but “I think they addressed some of the bigger concerns,” including the magnetic fields.
I’ll admit, I felt the same. So far in The Fight, we’ve chronicled examples where there are at least somewhat reasonable concerns about renewable energy development – stuff like batteries sited in wildfire risk areas and solar farms in imperiled tortoise habitat. But in this case, I watched the entire presentation online and left thinking this was essentially a non-issue.
Yet Paterson says she was unconvinced by the presentation. The projects they’re citing aren’t comparable, she claims. And then she has a laundry list of other complaints about the potential cables.
Hearing her talk about the transmission, you’d think she just doesn’t want this built under any circumstances. So I asked her if, given her allies, the goal is to stop offshore wind. An avid wildlife painter, she says no, and that she’s “very strongly in support of alternative energy.”
Well, okay. Maybe it’s political or partisan then? I asked her who she’s voting for in this year’s presidential election. “I don’t like anyone in the election to be quite honest,” she confessed, self-identifying simply as a “libertarian.” She then added: “I love the idea of Robert F. Kennedy [Jr.] revolutionizing our health-care system. That makes me very excited.”
Last week, Heatmap published a risk index of the top 10 renewable energy projects worth watching for potential cancellation or major blowback to the energy transition.
We listed Atlantic Shores in the top five, primarily citing the project’s current role as a focal point for opponents to offshore wind up and down the Atlantic coastline. Hours after the risk index was published, Atlantic Shores received its final approval from the Bureau of Ocean Energy Management.
Despite that win, we’re leaving the project on the index because the cables have to be built too – and that stands to be a more stressful fight.
It wasn’t supposed to be hard. In 2021, New Jersey passed a law granting the Board of Public Utilities the authority to supersede local governments opposing easements and other permits for offshore wind transmission cables. But that law’s permissibility under the state constitution hasn’t been tested yet, thanks to the cancellation of Orsted’s Ocean Wind project, which was set to be the likeliest battleground over cables before Atlantic Shores.
State officials are expected in the coming weeks to lay out who will actually build the transmission infrastructure and the route it’ll take from Sea Girt to the Larrabee substation. Between the day of that announcement and the completion of construction, a lot can go awry. Donald Trump could win the presidency and, as opponents of offshore wind expect, revisit permitting decisions for projects like Atlantic Shores. Or a Republican like Jack Ciattarelli could win the governor’s mansion, and that person could take any number of steps to undermine the cables like leaving the local control law undefended in state court if it’s challenged.
All this risk to the energy transition, started by a handful of actors with unfounded claims about magnetic fields.
I asked Atlantic Shores for comment on the opposition movement. They did not get back to me.
However, I did hear from the New Jersey Offshore Wind Alliance, a consortium of developers trying to build offshore wind off the state coast. “While we are advocates of civil discourse and engagement from communities, we urge residents to be mindful of prevalent misinformation,” said Paulina O’Connor, executive director of the alliance, in a statement sent to me Tuesday evening.
“By following best practices in environmental science and engineering, such as proper siting, minimizing disruption during construction, and adherence to all state and federal regulations, this infrastructure can be safely and responsibly integrated into our communities and local and regional power grids to provide resilient and reliable power to New Jersey homes,” O’Connor continued.
I also heard from Anjuli Ramos-Busot, executive director of Sierra Club’s New Jersey chapter, who contacted me last night after Atlantic Shores and the offshore wind alliance brought my reporting to their attention.
“Let us be clear, the microwave in your kitchen emits more electromagnetic currents than cables buried deep underground covered by insulation and concrete,” Ramos-Busot said in a statement. “This technology is vetted, goes through rigorous permitting standards, and is safe and responsible for both the environment and local communities.”
Candidly, I’m holding my breath on whether Sierra Club’s words will win over these concerned shore residents.

Why local governments are getting an earful about “infrasound”
As the data center boom pressures counties, cities, and towns into fights over noise, the trickiest tone local officials are starting to hear complaints about is one they can’t even hear – a low-frequency rumble known as infrasound.
Infrasound is a phenomenon best described as sounds so low, they’re inaudible. These are the sorts of vibrations and pressure at the heart of earthquakes and volcanic activity. Infrasound can be anything from the waves shot out from a sonic boom or an explosion to very minute changes in air pressure around HVAC systems or refrigerators.
Knowing some of these facilities also have the capacity to produce significant audible noise, growing segments of the population’s more tech-skeptical and health-anxious corners are fretting some data centers could be making a lot of infrasound, too. The whizzing of so many large computational machines combined with cooling fans and other large devices creating so many new columns of air flow. Add onto that any rotational onsite power generation – think natural gas turbines, for example – and you get quite a lot of movement that could potentially produce what they say is infrasound.
Some of the virality of this chatter about infrasound and data centers comes from a video about infrasound created by audio engineer and researcher Benn Jordan. Currently sitting at more than 1 million views, this short YouTube film documents claims that some data centers are operating like “acoustic weapons” through infrasound and harming people. Andy Masley, an “effective altruist” writer, has become the chief critic of the Jordan video, getting into a back-and-forth that’s raised the issue to Internet discourse territory.
The Jordan-Masley infrasound debate is honestly a bit of a mess. So I want to be clear: I’m not going to get into the science of whether or not infrasound poses any kind of public health risk in this article. We can get to that later. It’s worth saying that this subject may need more study and that work is ongoing. Also, talking about infrasound at all can make you honestly sound a little wacky (see: this study blaming people seeing ghosts on infrasound). It might also remind you of another panic in the Electric Age: electromagnetic fields, also known as EMFs. Developers of transmission lines and solar projects have long had to deal with people worried about transmission lines and large electrical equipment potentially glowing with invisible, unhealthy radiation.
In late 2024, I wrote about how an RFK Jr. supporter worried about this form of electrical emission was helping lead the fight against a transmission line in New Jersey for offshore wind. Maybe that’s why it didn’t surprise me one bit when the Health and Human Services secretary himself told a U.S. Senate Committee last week that he was asking the Surgeon General’s office to “do either meta reviews” or “base studies” on noise pollution and EMF radiation from data centers “so we can better inform the American public.”
“There’s a range of injuries that are very, very well documented. They’re neurological – very, very grave neurological injuries, cancer risk,” Kennedy Jr. told the Senate Health, Education, Labor and Pensions Committee on April 22 in response to a request from Sen. Josh Hawley of Missouri to study the issue. “The risks, to me, are tremendous.”
There’s also the unfortunate reality that infrasound impacts have previously been a cudgel to slow down renewable energy deployment. Wind turbines create infrasound because of the subharmonic frequencies created when one turbine rotates at a slightly different pace than another, producing a slightly dissonant low frequency noise. Groups like the Heartland Institute proudly list this infrasound as one of the reasons wind energy “menaces man and nature.”
But regardless of merit, this concern is already impacting local government decisions around data center projects, much like how one Michigan county sought to restrict solar energy on the same basis.
In February Adrian Shelley, the Texas director for environmental group Public Citizen, implored the city of Red Rock to study changing their noise ordinance to take into account infrasound. “It has effects on sleep patterns, on stress, on cardiovascular health, and it is potentially a very serious concern,” Shelley said at a February 11 city council discussion on data center rules. “It will not be covered by the city’s noise ordinance, which only deals with audible sound.”
Earlier this month in Calvert County, Maryland, a volunteer for their environmental commission recently told the county government that infrasound needs to be factored into their future data center planning. “It will have significant impacts on our region and the Chesapeake and the Patuxent because infrasound isn’t stopped by walls,” commission member Janette Wysocki, a proud land conservationist, said at an April 15 hearing. “It will keep going, it will move through anything. It’s a very long wavelength. So we need to protect our ecosystem.” Wysocki implored the county to consider whether to adjust its noise regulations.
Around the same time, similar concerns were raised in Lebanon, a small city in east-central Pennsylvania. “It permeates through concrete walls, it permeates through the ground,” Thomas Dompier, an associate professor at Lebanon Valley College, said at an April 16 Lebanon County commission hearing on data centers.
Lastly, last week I explained how Loudon County wants to rethink its noise ordinance to deal with low-frequency “hums” from data centers – a concern echoing those who fret infrasound.
Ethan Bourdeau, executive director of standards at Quiet Parks Intentional and a career acoustician and building standards writer, told me that what makes data centers unique is the “constant drone” of noise that could potentially carry subharmonic frequencies. Bourdeau said cities or counties could possibly factor concerns about infrasound into noise ordinances to address those who are most concerned. One way they could do it is by changing how decibels are weighted in the government’s measurements. A-weighting decibel meters are a common form of sound measurement geared toward perceptible noise. Using different systems, like C-weighting or G-weighting, would avoid ways that A-weighting can filter out sub-hearing frequencies.
“These are reporting and weighting systems where a sound level meter taking background noise receives all the unweighted sound and then you apply all these filters afterwards, like an EQ curve,” Bourdeau said.
So I guess if those most concerned about infrasound have their way, a lot of country commissioners and local elected leaders will be heading to the mixing booth.
And more on the week’s top fights around project development.
1. King County, Washington – The Moss Landing battery backlash is alive and well more than a year after the fiery disaster, fomenting an opposition stampede that threatens to delay a massive energy storage project two dozen miles east of Seattle.
2. Prince Williams County, Virginia – It was a big week for data center troubles. Let’s start with Data Center Alley, which started to show cracks this week as data center developer Compass announced it was pulling out of the controversial Digital Gateway mega-project.
3. Washtenaw County, Michigan – Turning to Michigan, real estate firm Sansone abandoned plans to purchase land owned by Toyota to build a hyperscale data center campus after the local township instituted a 6-month moratoria.
4. Okeechobee County, Florida – The backlash to data centers is killing projects in deep-red Florida too, as this county’s commission decides to kill a 205-acre prospective data center campus led by a state college.

A conversation with Holly Jean Buck, author of a buzzy story about Bernie Sanders’ proposal for a national data center moratorium.
This week’s conversation is with Holly Jean Buck, an associate professor at the University of Buffalo and former official in the Energy Department’s Office of Fossil Energy and Carbon Management. Buck got into the thicket of the data center siting debate this past week after authoring a polemic epistemology of sorts in Jacobin arguing against a national data center ban. In the piece, she called a moratorium on AI data centers “a massive strategic blunder for the left, and we should think through the global justice implications and follow-on effects.” It argued that environmental and climate activists would be better suited not courting a left-right coalition that doesn’t seem to have shared goals in the long term.
Her article was praised by more Abundance-leaning thinkers like Matthew Yglesias and pilloried by some of the more influential people in the anti-data center organizing space, such as Ben Inskeep of Citizens Action Coalition of Indiana. So I wanted to chat with her about the discourse around her piece. She humbly obliged.
The following conversation was lightly edited for clarity.
So my first question is kind of a broad one and perhaps a suitable polemic to open with: are data center moratoria (bans) “slopulism”?
Haha, oh no. I don’t know if I have a working definition of that term.
“Slopulism” is colloquially known as low-effort or performative populism slop that is focused on emotional gratification and elite resentment instead of substantive policy.
I think, sometimes? Moratoria have been proposed at a lot of different levels in a lot of different forms. With the national moratorium, as written in the AI Data Center Moratorium Act [proposed by Senator Bernie Sanders and Representative Alexandria Ocasio-Cortez], I thought from a rhetorical and textual standpoint it was a pretty amazing document. I just don’t think it’s a great policy proposal, so maybe that’s a little bit closer, but I don’t think people working on that theory of change would see it as slopulism. They’re thinking of this as a negotiating tactic and thinking, how do we leverage this moment and make it clear to the tech industry they don’t have social license?
I wouldn’t personally call it slopulism. I just don’t think it’ll work. I don’t think it's effective but I'm not big on labels.
Personally, I come down sort of where you’re at on the yes-and-no kind of tack. There’s definitely some vibes based stuff going on, which you address in your piece, but historically there’s a pretty long legacy of advocacy campaigns for, well, let’s ban this until we’ve finished regulating it.
You write part of why a moratoria push can be a dead end is that the right and left coalitions pushing to stop data centers have different interests on other issues and that it may not follow that stopping data centers will result in a clean energy buildout, or the social policies to address job displacement.
When you talk about the left-right coalition, help me understand what’s driving the opposition and why you think it’s happening the way it is?
I think there’s a lot of layers here. It’s pretty complex. It’s well established there are left-right coalitions. I don’t think we have a great body of social science research but I think that is a solid working assumption. So I think the people who are a part of this, it’s easy for them to come together and stop a thing that’s happening near them. But I don’t think they’re going to agree on how we build a decarbonized, resilient grid. The people in that coalition are going to have vastly different perspectives on whether we want to decarbonize, what measures are feasible and worth paying for to get there. Same thing when it comes to the thornier questions about AI governance. The solution set is just not something the members of that coalition are going to agree on.
So it feels maybe on the ground like this really cool moment about rising up against these big forces. It’s cool. I get it. I was actually very much on board with that a while ago. And my views on that have shifted. I don’t think it’s going to be productive unless it’s coupled with a lot of very real coalition building work I don’t see happening.
I’ve had conversations with environmental activists about that issue. I did a Q&A with someone from Public Citizen about this particular issue right after the national data center moratoria was introduced with Senator Sanders. I asked, do you have any concerns about pushing for a moratoria on new tech infrastructure when this tool is also used by those trying to stop solar, wind and batteries? Is there any concern that in some communities it’ll go from data centers to renewables?
I wondered reading your piece if this is part of what you’re getting at here, that this backlash doesn’t necessarily seem to be rooted as much in a transition away from fossil fuels or building lots of new renewable energy.
I think in the absence of systematic research, it’s one of these things where people can see it the way they want, through their own lens.
I’ve been following this in a few different places in the country, especially through online Facebook groups, and there is a noticeable overlap between some of those Facebook groups and the content and many of the anti-renewable groups I follow. Some of the themes remind me of this piece I wrote about para-environmentalism. There’s a lot of places where it dips into conspiracy and fears about new technology, electro-magnetic radiation, sorts of places where a data center is mundane but can take on creepy, supernatural overtones in some of these groups. Before I was studying para-environmentalism more generally I was thinking we really need this left-right coalition to rise up against these companies. Now I’m much more cautious about where it’ll lead.
I know Twitter isn’t real life, but the discourse around your work – those who have criticized it – are saying, why can’t we do both? Why can’t we go after the data center sector without potentially heading towards that form of politics you’re afraid of?
I don’t think it's the moratoria necessarily but the left-right blocking approach.
There’s a couple things I want to make discernments about. I want to make a discernment between people who want to stop a data center and a moratorium that’s more of a blanket, larger regional or national thing. I do think there are data centers being sited in really bad places, under really bad agreements. They shouldn’t move forward.
There’s bad data centers and there’s okay data centers and we need to be discerning between them. There’s also normal processes in this country for siting large facilities, whether they’re county level zoning commissions and something else.
But to your question of why can’t we do both, we could have a viable left-right anti-tech organizing that makes real demand for how we go about the lithium and AI age if people were investing in the social infrastructure necessary to make that happen. We’re very far from it because the framing of stopping a thing… We need people who are convening real conversations about what to do. I think they’re focused on stopping a thing.
I don’t know if they’re focused on whether we need universal basic income, a public wealth fund or something else, in a way that’s across the aisle. That would be a whole movement building infrastructure and it’s one we need if we’re going to decarbonize.
But that’s not what I am seeing – I’m seeing NGOs funded by wealthy and non-transparent donor-advised funds focused on some parts of the country and not others. We’re not getting to having those conversations happening or even having a shared media reality.
Can you go a bit deeper on how a situation where there is a national moratoria results in equity concerns? How are those less fortunate hurt by that?
There are three things I am concerned about. The first thing is that people who are better organized because they have more resources say we need a national moratoria which pushes development to regions with weaker organizing. Maybe they have weaker environmental and social regulations. I’m concerned about that because there’s a huge history of that happening across different regions and industries.
The second thing I am concerned about is driving up the cost of computation in ways that would make AI less affordable and accessible for people who may be able to use it for a variety of things. I realize that’s controversial for the segment of the population who thinks AI is useless but I think it’s tremendously valuable and I want a world where everybody has access to these capabilities and I think it’s made less likely by making computation less expensive.
The third thing, which I didn’t have room in my piece to address, is to what extent this moment is about the data centers. This is a new focus for the climate movement, which is understandable because there’s been a sideshift away from climate and the Trump administration has put everything in such a dire place that they need wins to hold on to. I’m worried about whether that displaces energy and funding away from other environmental issues. Are we taking space away from other priority areas? I’m not saying we know about those things but these are concerns we need to focus on. And if they’re not concerns, that’s good news. But we should think of them.
On that note, on the bigger question, do you believe artificial intelligence and these data centers are a net positive or a net negative for the effort to solve for climate change?
I think it’s too soon to say what the net effect will be and that net effect will be indirect. We can count the carbon emissions from these and say, great we have a whole new industrial sector to contend with among all these other industries we’re trying to decarbonize. And it’s bad from that point of view.
Then you have efficiencies that AI might discover. I have no clue about the extent of that.
Then you have AI impacting the information ecosystem, what they want to believe and what they want to do. Maybe the greatest impacts of AI will be it causes people to take climate more seriously. Or ways through social media that convince people it is a hoax.
It’s hard to measure all these factors and speculations against each other. So I have no idea what the net effect will be on climate and I don’t believe anyone who says they know what it’ll be at this point.
But the data centers – from your perspective, is this boom helping or hurting?
I think it’s definitely a setback. But if I look at the whole picture of climate change I think this is more tractable than some of the challenges we have with decarbonization. Number one, we know how to decarbonize data centers. It’s a lot harder than something like cement where we don’t know how to stop the emissions themselves. I think agriculture is really challenging to decarbonize – it’s mixed up in what people eat and land use. Data centers is a problem. But it seems tractable because of that.
We also have all these people working on this. All of these climate professionals who’ve pivoted to framing their work into being about AI. I think we have the knowledge and the personnel to do it. If I compare data centers to other parts of decarbonization, it’s not on the top of my list of things I’m worried about. But it is tough – we knew we had this many tonnes to deal with and now we’re adding things. It’s a challenge but I want to have perspective about the challenge.
Can I close on a fun question?
Sure.
What’s the last song you listened to?
Oh, gee. It was some terrible ‘80s song because my kind is really into that kind of music right now. The one that sticks out is “Sunglasses At Night,” which is always playing in the Buffalo airport.
