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.

It’s aware of the problem. That doesn’t make it easier to solve.
The data center backlash has metastasized into a full-blown PR crisis, one the tech sector is trying to get out in front of. But it is unclear whether companies are responding effectively enough to avoid a cascading series of local bans and restrictions nationwide.
Our numbers don’t lie: At least 25 data center projects were canceled last year, and nearly 100 projects faced at least some form of opposition, according to Heatmap Pro data. We’ve also recorded more than 60 towns, cities and counties that have enacted some form of moratorium or restrictive ordinance against data center development. We expect these numbers to rise throughout the year, and it won’t be long before the data on data center opposition is rivaling the figures on total wind or solar projects fought in the United States.
I spent this week reviewing the primary motivations for conflict in these numerous data center fights and speaking with representatives of the data center sector and relevant connected enterprises, like electrical manufacturing. I am now convinced that the industry knows it has a profound challenge on its hands. Folks are doing a lot to address it, from good-neighbor promises to lobbying efforts at the state and federal level. But much more work will need to be done to avoid repeating mistakes that have bedeviled other industries that face similar land use backlash cycles, such as fossil fuel extraction, mining, and renewable energy infrastructure development.
Two primary issues undergird the data center mega-backlash we’re seeing today: energy use fears and water consumption confusion.
Starting with energy, it’s important to say that data center development currently correlates with higher electricity rates in areas where projects are being built, but the industry challenges the presumption that it is solely responsible for that phenomenon. In the eyes of opponents, utilities are scrambling to construct new power supplies to meet projected increases in energy demand, and this in turn is sending bills higher.
That’s because, as I’ve previously explained, data centers are getting power in two ways: off the existing regional electric grid or from on-site generation, either from larger new facilities (like new gas plants or solar farms) or diesel generators for baseload, backup purposes. But building new power infrastructure on site takes time, and speed is the name of the game right now in the AI race, so many simply attach to the existing grid.
Areas with rising electricity bills are more likely to ban or restrict data center development. Let’s just take one example: Aurora, Illinois, a suburb of Chicago and the second most-populous city in the state. Aurora instituted a 180-day moratorium on data center development last fall after receiving numerous complaints about data centers from residents, including a litany related to electricity bills. More than 1.5 gigawatts of data center capacity already operate in the surrounding Kane County, where residential electricity rates are at a three-year high and expected to increase over the near term – contributing to a high risk of opposition against new projects.
The second trouble spot is water, which data centers need to cool down their servers. Project developers have face a huge hurdle in the form of viral stories of households near data centers who suddenly lack a drop to drink. Prominent examples activists bring up include this tale of a family living next to a Meta facility in Newton County, Georgia, and this narrative of people living around an Amazon Web Services center in St. Joseph County, Indiana. Unsurprisingly, the St. Joseph County Council rejected a new data center in response to, among other things, very vocal water concerns. (It’s worth noting that the actual harm caused to water systems by data centers is at times both over- and under-stated, depending on the facility and location.)
“I think it’s very important for the industry as a whole to be honest that living next to [a data center] is not an ideal situation,” said Caleb Max, CEO of the National Artificial Intelligence Association, a new D.C.-based trade group launched last year that represents Oracle and myriad AI companies.
Polling shows that data centers are less popular than the use of artificial intelligence overall, Max told me, so more needs to be done to communicate the benefits that come from their development – including empowering AI. “The best thing the industry could start to do is, for the people in these zip codes with the data centers, those people need to more tangibly feel the benefits of it.”
Many in the data center development space are responding quickly to these concerns. Companies are clearly trying to get out ahead on energy, with the biggest example arriving this week from Microsoft, which pledged to pay more for the electricity it uses to power its data centers. “It’s about balancing that demand and market with these concerns. That’s why you're seeing the industry lean in on these issues and more proactively communicating with communities,” said Dan Diorio, state policy director for the Data Center Coalition.
There’s also an effort underway to develop national guidance for data centers led by the National Electrical Manufacturers Association, the American Society of Heating, Refrigerating, and Air-Conditioning Engineers, and the Pacific Northwest National Laboratory, expected to surface publicly by this summer. Some of the guidance has already been published, such as this document on energy storage best practices, which is intended to help data centers know how to properly use solutions that can avoid diesel generators, an environmental concern in communities. But the guidance will ultimately include discussions of cooling, too, which can be a water-intensive practice.
“It’s a great example of an instance where industry is coming together and realizing there’s a need for guidance. There’s a very rapidly developing sector here that uses electricity in a fundamentally different way, that’s almost unprecedented,” Patrick Hughes, senior vice president of strategy, technical, and industry affairs for NEMA, told me in an interview Monday.
Personally, I’m unsure whether these voluntary efforts will be enough to assuage the concerns of local officials. It certainly isn’t convincing folks like Jon Green, a member of the Board of Supervisors in Johnson County, Iowa. Johnson County is a populous area, home to the University of Iowa campus, and Green told me that to date it hasn’t really gotten any interest from data center developers. But that didn’t stop the county from instituting a one-year moratorium in 2025 to block projects and give time for them to develop regulations.
I asked Green if there’s a form of responsible data center development. “I don’t know if there is, at least where they’re going to be economically feasible,” he told me. “If we say they’ve got to erect 40 wind turbines and 160 acres of solar in order to power a data center, I don’t know if when they do their cost analysis that it’ll pencil out.”
Plus a storage success near Springfield, Massachusetts, and more of the week’s biggest renewables fights.
1. Sacramento County, California – A large solar farm might go belly-up thanks to a fickle utility and fears of damage to old growth trees.
2. Hampden County, Massachusetts – The small Commonwealth city of Agawam, just outside of Springfield, is the latest site of a Massachusetts uproar over battery storage…
3. Washtenaw County, Michigan – The city of Saline southwest of Detroit is now banning data centers for at least a year – and also drafting regulations around renewable energy.
4. Dane County, Wisconsin – Another city with a fresh data center moratorium this week: Madison, home of the Wisconsin Badgers.
5. Hood County, Texas – Last but not least, I bring you one final stop on the apparent data center damnation tour: Hood County, south of the Texas city of Fort Worth.
A conversation with San Jose State University researcher Ivano Aiello, who’s been studying the aftermath of the catastrophe at Moss Landing.
This week’s conversation is with Ivano Aiello, a geoscientist at San Jose State University in California. I interviewed Aiello a year ago, when I began investigating the potential harm caused by the battery fire at Vistra’s Moss Landing facility, perhaps the largest battery storage fire of all time. The now-closed battery plant is located near the university, and Aiello happened to be studying a nearby estuary and wildlife habitat when the fire took place. He was therefore able to closely track metals contamination from the site. When we last spoke, he told me that he was working on a comprehensive, peer-reviewed study of the impacts of the fire.
That research was recently published and has a crucial lesson: We might not be tracking the environmental impacts of battery storage fires properly.
The following conversation was lightly edited for clarity.
Alright let’s start from the top – please tell my readers what your study ultimately found.
The bottom line is that we detected deposition of fine airborne particles, cathode material – nickel, manganese, and cobalt – in the area surrounding the battery storage facility. We found those particles right after the fire, immediately detected them in the field, sampled the soils, and found visible presence of those particles using different techniques. We kept measuring the location in the field over several months after the fire.
The critical thing is, we had baseline data. We had been surveying those areas for much longer before the fire. Those metals were in much higher concentration than they were before, and they were clearly related to the batteries. You can see that. And we were able to see changes in surface concentrations in the soils over time, including from weather – once the rains started, there was a significant decrease in concentrations of the metals, potentially related to runoff. Some of them migrated to the soil.
What we also noticed is that the protocols that have been used to look at soil contamination call for a surface sample of 3 inches. If your sample thickness is that and the layer of metal deposit is 1 millimeter or 5 millimeter, you’re not going to see anything. If you use standard protocols, you’re not going to find anything.
What does that mean for testing areas around big battery storage fires?
That’s exactly what I hope this work helps with. Procedures designed in the past are for different types of disasters and incidents which are more like landslides than ash fallout from a fire. These metal particles are a few microns thick, so they slide easily away.
It means we have to rethink how we go about measuring contamination after industrial fires and, yes, battery fires. Because otherwise it’s just completely useless – you’re diluting everything.
The other thing we learned is that ashfall deposits are very patchy. You can get different samples between a few feet and find huge differences. You can’t just go out there and take three samples in three places, you have to sample at a much higher resolution because otherwise you’ll miss the whole story.
When it comes to the takeaways from this study, what exactly do you think the lessons should be for the battery companies and regulators involved?
There are a lot of lessons we learned from this fire. The first is that having baseline data around a potential fire site is important because then you can better understand the after.
Then, the main way to assess the potential hazards during the fire and after the fire are air quality measurements. That doesn’t tell you what’s in the air. You could have a high concentration of pollen, and then you know the quality of the air, but if you replace that with metal it is different. It’s not just how much you’re breathing, but what you are breathing.
Also, fast response. [Vistra] just released a report on soil saying there was nothing … but the sampling was done eight months after the fire. Our study shows after the fire you have this pulse of dust, and then it moves. Stuff moves to soil, across habitat. So if you don’t go out there right away, you might miss the whole thing.
Finally, what we found was that the fallout from the fire was not a bullseye pattern centered at the facility but rather offset kilometers away because of the wind.
We didn’t know much about this before because we didn’t have a real case study. This is the first real live event in which we can actually see the effects of a large battery burning.
