A conversation with Rebecca Barel and Dan Cassata of Columbia

This week’s Q&A is a change of pace. I was contacted by two student researchers – Rebecca Barel and Dan Cassata – requesting to interview me for some policy and social science research they’ve been up to at Columbia University sponsored by the policy organization Clean Tomorrow.
Then it hit me like a ton of bricks: Wouldn’t it be neat if I interviewed academics engaging in this research about their experience doing this work in such a hostile political environment?
So I asked Rebecca and Dan if our conversation could wind up being a bit of a dialogue, instead of something one-sided. Much to my satisfaction, they agreed – and I wound up getting a lot more hopeful by the end of our talk than I was when it started.
Anywho, the following chat has been edited for clarity. Let’s take it away?
Tell me about your research project, first and foremost.
Dan: The project writ large, the central idea of it is there’s this suite of either policy or non-policy mechanisms we can use to take benefits that accrue from a renewables project and deliver them to a local community, as opposed to let’s say an extractive model. The project is trying to understand what that suite of tools look like and to what extent any of those tools have an influence on public opinion. You’ve done a lot of reporting on community backlash, community opposition. We’re trying to understand how much of this opposition is coming from this view: benefits aren’t coming to us, so why should we support this?
It feels like we can actually add value here. Sometimes when you do grad school research, you’re just putting stuff on paper to get a degree and not doing anything meaningful.
I wanted to talk about this with you because I love conversations with those who, like myself, are obsessed with this niche issue. Can you tell me more about the experience of researching conflicts in renewable energy development right now, amid the war on climate action and renewable energy generally? How does it feel to be doing this research at this time?
Rebecca: I can take that – I mean, in California specifically, one of the mechanisms was that the offshore wind leases are required to have community benefit agreements and a labor agreement. I had an interview with someone who’d written about this topic yesterday who said, quick question – where do you see this going? What’s happening now that Trump is so anti-offshore wind? And I said, That’s what I was going to ask you. Most of my research is at this point coming from Heatmap, because most of the mainstream news outlets aren’t concerned with these issues. They’re bogged down with the visa situations, and being at Columbia is an interesting experience right now.
Dan: Rebecca touched on this but to be more explicit – it is entirely up to the state governments. We’re not looking at the federal policies. That’s not to say there aren’t uncertainties that come with that, and federal incentives obviously matter. Whether or not a project is going to pencil depends on federal incentives. But focusing on the state level has created more of a lane where our work can still feel relevant and be completely overturned and what not.
I’d ask you, Jael – are they more or less confident about opposing projects now that Trump’s in office?
Maybe. There’s certainly some degree of emboldened opposition. I see that as a journalist and I wonder what place there is for the research you’re doing – I wonder how it will be used.
Dan: The dimensions on which some of this is happening is separate from the politics, and that’s a note of optimism from me I guess. You can structure things and it might not be as uniform and widespread as you would like but there are places where you can work and be effective.
Rebecca: I’d add the renewable energy debate, there’s a broader question of what will win out in America over the next few years. Money in pocket or charismatic propaganda that motivates how people vote and what people choose to back. I think we’re at a crux in that right now because of the tariffs but in Texas, generally, if you were to put the people in that area into a box – they might have MAGA hats but at the end of the day, they’re about the money in their pocket. That’s how we ordinarily think of American voters.
I feel like money in my pocket might win, but it’s going to take a while.
How much interest in your work have you seen from the private sector or public officials?
Dan: We’ve spoken to public commissioners at the county level. I had a call right before this conversation with someone from a state-level public service commission. Everyone gets back to us. I do think the private sector has been less engaged. I don’t know if that’s less of an interest though – I read it as the private sector not tending to talk about their work with folks like us very often. There’s not that much in it for them.
Dan: I’d like to ask you this Jael – does it feel like community engagement is a meaningful thing?
This edition of the newsletter will begin with a company accusing a township of soliciting a bribe after years of moving goalposts and redlines. I’m not that optimistic.
Where do you see policy being a solution in this circumstance?
Dan: Let’s take as a given that community benefit agreements work. The research – and what we’ve found – is that that’s not really a given. But they can work. And there are states like New York and California that have legislation that heavily incentivizes developers to go through this process of community engagement to qualify for tax credits or get permits. The reason that we are doing this research is because if you were able to have a case that this is really effective at improving projects and the speed of getting buy-in – we’d argue in our [eventual] report that this type of legislation should become more widespread.
If the conclusion is these things don’t seem to be impactful, then that’s where it justifies the case to look at this other suite of mechanisms that might be more helpful. For projects of a certain size, in New York for example, you can circumvent local zoning regulations and go through a state approval process.
The last thing I’ll ask: what gives you hope at this moment?
Dan: There’s obviously a lot of things that are going poorly right now when it comes to policy at the federal level on the energy transition. But I just think the ship has sailed – the boat might take longer to get there but the ship has left the port, and renewables are cost competitive if not cheaper than fossil energy.
Rebecca: There are people trying to do bad things and bad faith actors in power, but there are a lot of people trying really hard to make things better, and as long as there are people trying – there is a chance. It might take longer, and we might be slowed down, but for me what brings me hope is that every conversation I have with someone smart and capable and actively doing something to improve the environment, we’re not done yet.

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.
