A conversation with J. Timmons Roberts, executive director of Brown University’s Climate Social Science Network

This week’s interview is with Brown University professor J. Timmons Roberts. Those of you familiar with the fight over offshore wind may not know Roberts by name, but you’re definitely familiar with his work: He and his students have spearheaded some of the most impactful research conducted on anti-offshore wind opposition networks. This work is a must-read for anyone who wants to best understand how the anti-renewables movement functions and why it may be difficult to stop it from winning out.
So with Trump 2.0 on the verge of banning offshore wind outright, I decided to ask Roberts what he thinks developers should be paying attention to at this moment. The following interview has been lightly edited for clarity.
Is the anti-renewables movement a political force the country needs to reckon with?
Absolutely. In my opinion it’s been unfortunate for the environmental groups, the wind development, the government officials, climate scientists – they’ve been unwilling to engage directly with those groups. They want to keep a very positive message talking about the great things that come with wind and solar. And they’ve really left the field open as a result.
I think that as these claims sit there unrefuted and naive people – I don’t mean naive in a negative sense but people who don’t know much about this issue – are only hearing the negative spin about renewables. It’s a big problem.
When you say renewables developers aren’t interacting here – are you telling me the wind industry is just letting these people run roughshod?
I’ve seen no direct refutation in those anti-wind Facebook groups, and there’s very few environmentalists or others. People are quite afraid to go in there.
But even just generally. This vast network you’ve tracked – have you seen a similar kind of counter mobilization on the part of those who want to build these wind farms offshore?
There’s some mobilization. There’s something called the New England for Offshore Wind coalition. There’s some university programs. There’s some other oceanographic groups, things like that.
My observation is that they’re mostly staff organizations and they’re very cautious. They’re trying to work as a coalition. And they’re going as slow as their most cautious member.
As someone who has researched these networks, what are you watching for in the coming year? Under the first year of Trump 2.0?
Yeah I mean, channeling my optimistic and Midwestern dad, my thought is that there may be an overstepping by the Trump administration and by some of these activists. The lack of viable alternative pathways forward and almost anti-climate approaches these groups are now a part of can backfire for them. Folks may say, why would I want to be supportive of your group if you’re basically undermining everything I believe in?
What do you think developers should know about the research you have done into these networks?
I think it's important for deciding bodies and the public, the media and so on, to know who they’re hearing when they hear voices at a public hearing or in a congressional field hearing. Who are the people representing? Whose voice are they advancing?
It’s important for these actors that want to advance action on climate change and renewables to know what strategies and the tactics are being used and also know about the connections.
One of the things you pointed out in your research is that, yes, there are dark money groups involved in this movement and there are outside figures involved, but a lot of this sometimes is just one person posts something to the internet and then another person posts something to the internet.
Does that make things harder when it comes to addressing the anti-renewables movement?
Absolutely. Social media’s really been devastating for developing science and informed, rational public policymaking. It’s so easy to create a conspiracy and false information and very slanted, partial information to shoot holes at something as big as getting us off of fossil fuels.
Our position has developed as we understand that indeed these are not just astro-turf groups created by some far away corporation but there are legitimate concerns – like fishing, where most of it is based on certainty – and then there are these sensationalized claims that drive fears. That fear is real. And it’s unfortunate.
Anything else you’d really like to tell our readers?
I didn’t really choose this topic. I feel like it really got me. It was me and four students sitting in my conference room down the hall and I said, have you heard about this group that just started here in Rhode Island that’s making these claims we should investigate? And students were super excited about it and have really been the leaders.

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.
