On a potential deregulatory slowdown, community solar’s dimming, and Pope Leo on climate

Current conditions: Tropical Storm Imelda is set to gain intensity this week and whip the southeastern U.S. with soaking rain and storm surge • Frigid night air is forecast across northern New England • Typhoon Bualoi is flooding broad swaths of Vietnam, Thailand, and Laos.

The federal government shut down at 12:01 a.m. this morning after President Donald Trump and Republicans failed to reach a deal with Democrats in Congress on a bill to keep its funding flowing. That could slow the Environmental Protection Agency’s deregulatory effort, E&E News reported Tuesday. “The political crisis that threatens to shutter much of the federal bureaucracy at midnight comes as Administrator Lee Zeldin is racing to unravel high-profile rules on things like climate science, vehicle pollution, power plants, oil and gas wells, and carbon emissions reporting,” reporter Jean Chemnick wrote. An abrupt halt to the agency’s activities would at the very least set back Zeldin’s reform effort, including an agency reorganization set to begin this month.
The Department of the Interior, meanwhile, sent employees an email Tuesday warning that the agency “has contingency plans in place for executing an orderly shutdown of activities that would be affected by any lapse in appropriations forced by Congressional Democrats.” Neither Interior nor the EPA had published updated shutdown plans taking into account staff reductions under the current Trump administration as of Tuesday.
When the Department of Defense bought a 15% stake in MP Materials, the continent’s only active rare earths mine, The Economist called it the most significant entry by the federal government into a private market since the railroads were nationalized in World War I. (Biden administration officials were admittedly jealous, as Heatmap’s Matthew Zeitlin reported.) Now the Trump administration has taken another share of a major mineral project. The Department of Energy’s Loan Programs Office said Tuesday that it had renegotiated a multi-billion-dollar loan to back construction of Lithium Americas’ Thacker Pass lithium mine in Nevada. The project, on track to become the Western Hemisphere’s largest lithium producer by 2028, will transform a remote stretch of high Nevada desert into a lithium clay mine, harvesting from one of the world’s richest known deposits.
Under the new deal, the federal government will take a 5% equity stake in Lithium Americas and an additional 5% ownership of the company’s joint venture with General Motors. The Energy Department called its stakes “part of the overall collateral package on a loan, helping to reduce repayment risk for taxpayers.” But the announcement said the “revised agreement” includes “robust loan amendments,” notably “more than $100 million of new equity.”

Community solar installations are plunging. After a record-breaking 2024, installations of new panels in small-scale cooperative or community solar projects dropped 36% in the first half of this year compared to the same period last year. The passage of the One Big Beautiful Bill Act slashed the cumulative five-year outlook for community solar by 8% compared to the outlook before the legislation repealed vast chunks of the Inflation Reduction Act. That’s according to a new analysis from Wood Mackenzie.
Yet Jeff Cramer, the chief executive of the Coalition for Community Solar Access, said states are stepping up “with historic expansions like New Jersey’s 3,000 megawatts and Massachusetts’ 900 megawatts.” He added: “These bright spots show what’s possible when policymakers work to unlock capacity. At the same time, this report makes clear the challenges ahead — from federal uncertainty to interconnection delays and program caps — that must be addressed to realize the full potential of community solar and deliver the resilient, affordable power communities are asking for.”
Most Americans say that rising electricity prices have at least “a decent amount” of impact on household finances. “Still, for about 40% of the country, those high prices are more a pinch than a pain,” Heatmap’s Robinson Meyer wrote. That’s the finding of a new Heatmap Pro poll on rising rates. The results had some predictable outcomes, including that more than 70% of voters with household incomes below $50,000 said rising bills were a problem with “a lot of" impact on spending. Upward of 62% of voters earning less than $100,000 described similar issues, as did 59% of white voters without a college degree.
It’s been difficult for “Vatican-watchers” to pin down Pope Leo XIV’s views on most issues. But “on climate change,” The New York Times wrote on Tuesday, “it is clear that he is moved by the topic, and particularly its disproportionate harm to poor and vulnerable people.” The world is about to get a lot more clarity on his views. On Wednesday, the Pontiff is scheduled to give his first address on climate change at a conference taking place at the Papal Palace of Castel Gandolfo.
The remarks come on the 10th anniversary of Laudato Si, a groundbreaking papal document written by the late Pope Francis that overhauled the Catholic Church’s teachings on climate change. The 2015 encyclical was widely credited with pushing forward carbon-cutting negotiations at the global climate summit in Paris that year.
Africa's biggest petrostate is having a solar boom. Nigeria became Africa’s second-largest importer of solar panels over the past year by overtaking Egypt. The imports total 1.7 gigawatts. “It is a response to a problem … You can’t rely on a 24/7 grid in most parts of Nigeria at the moment,” Ashvin Dayal, senior vice-president of power at Rockefeller Foundation, which backed the mini-grid project, told the Financial Times. “Demand is booming for reliable, affordable electricity both for inside the home, but also to run small businesses, to run agricultural appliances, to increase productivity and incomes.”

The data center boom is everywhere you look in U.S. economic and emissions data.
This is an edition of Heatmap Daily, an evening review of the day’s news written by our executive editor. Sign up for it here.
It isn’t exactly a new thought, but I’ve been struck recently by how many trends in America’s economic and environmental data are fundamentally about the data center boom and the return of electricity demand:
First, the Energy Information Administration reported this week that U.S. emissions grew by more than 2% last year, driven by surging electricity demand and an increase in coal-fired generation.What caused that higher power demand? New factories and data centers — as well as record summertime cooling demand.
Second, many of the new factories driving that higher power demand are themselves producing goods that are … let’s say … data center-adjacent. There are the enormous new semiconductor fabs, of course. But Ford and General Motors have also set up new production lines (or repurposed old ones) to manufacture grid-scale batteries to meet power demand.
Third, take a look at the recent U.S. spending on private non-residential construction — in other words, everything American companies are building that is not houses, condos, or apartments.
The construction industry’s spent almost $60 billion on data centers over the past year, which is more than it spent on all other office buildings combined (and more than it spent building warehouses, too). Just a handful of categories — data centers, power plants, electricity infrastructure, and certain kinds of electronics manufacturing — now make up a third of all U.S. private non-residential construction investment. They’ve never made up such a large share of construction spending since data collection began in 2014.
As The New York Times recently noted, the American economy is unusually dependent on the American stock market right now — and the stock market is unusually dependent on artificial intelligence. This week, investors started to balk at the enormous spending hyperscalers are planning to keep building out the AI boom; Alphabet’s shares dropped 8% this week after it boosted its planned 2026 capital expenditure and signaled 2027 will be even bigger. If the data center boom started to slow down in earnest, then more than just that budget will change.
Speaking of which, my colleague Emily Pontecorvo wrote earlier this week about how many businesses are struggling to even estimate their carbon emissions from artificial intelligence. The carbon accounting startup Watershed recently unveiled a new formula to help companies get a sense of their AI-related emissions.
But even that formula is still limited by the amount of data hyperscalers publish — and they don’t publish that much. Google, for instance, is the only AI company that has (laudably) provided estimates of its emissions on a per-prompt basis. Yet no company has published its per-token emissions, or how emissions sync up with particular models or regions.
So Emily asked Google: Why aren’t you — or any other model provider — disclosing this kind of data yet?
The tech company didn’t get back to us until after we’d published Emily’s story. But its response was interesting enough that I wanted to quote some of it here.
The problem is “industry consensus,” Cooper Elsworth, a Google spokesperson, told us. “There is currently very little consensus on how to comprehensively and fairly measure the serving environmental impact of generative AI (such as text generation),” he wrote. “Without standardized, ‘apples-to-apples’ frameworks, it is difficult to compare different providers accurately.”
That’s partly because energy use — and emissions data — can vary from site to site and depend on “custom-built hardware, software compilers, and advanced inference techniques.” And he claimed Google doesn’t always have the measurement hardware in place to provide such specific estimates: “Providing precise, repeatable data requires highly advanced measurement infrastructure,” he said. “For example, software-based energy monitoring tools often suffer from sampling biases. For our study, we had to step away from top-down averages and directly measure actual energy at the physical power supply unit (PSU) level across our deployed fleet. Not all providers have the telemetry or data sets required to benchmark their operations at this level of granularity.”
Read Emily’s story to understand the other reasons why estimating — or even “guesstimating” — AI-related carbon emissions is so challenging.
A conversation with Emma Uridge of the Kansas Health Institute.
This week’s conversation is with Emma Uridge, analyst with the Kansas Health Institute. Uridge spent copious hours analyzing state and local laws on data center development to best understand how policymakers are responding to the potential environmental public health impacts of large AI infrastructure, including power and water. The report, which came out this week, also goes in depth into those health impacts. I reached out to her to discuss what she sees as must-watch territory for our readers on this emerging policy arena.
Our conversation was lightly edited for clarity.
What is actually being done on policy when it comes to data centers — beyond moratoria of course?
So first I’d like to just talk about the point of moratoria. It’s helpful to talk about how these policies emerge in the first place. One area where moratoria are helpful is when a data center is proposed but the county has no approach for how they’d like to potentially regulate them. That’s temporary, most of the time. It lets local governments conduct research on the various impacts and also negotiate community benefits, ones that can mitigate any potential negative impacts — like Lancaster Pennsylvania, which instituted a community benefit agreement that maximized the potential benefits of development while mitigating what large data centers can do. That agreement looked at capping municipal water use at 20,000 gallons per day and requiring 100% clean energy. It had financial penalties for non-compliance. The company also committed $20 million to their local economic development and clean energy fund. There are ways to negotiate with developers.
We also see amendments to existing zoning. Data center proposals are increasingly popping up in rural areas, many of which are unzoned, so there’s no way a county can negotiate unless there’s a moratorium in place.
Other policy solutions include different performance standards or requiring on-site renewable energy, like what Jefferson County, Missouri, looked at. Also setback requirements, mandatory noise buffers, ending by-right zoning.
Where are local governments getting ideas for regulating data centers?
A lot of the technical information comes from developers. That can in cases be seen as a biased source of information. I wouldn’t say there’s a dedicated group providing assistance to local governments when a project is proposed — which is a similar story to wind industry development, where we have only a handful of consultants who provide technical advice. It can be really helpful to get a multi-disciplinary approach to hearing information. It can be helpful to have the utility commission, public health folks, those in academia, as well as the developer.
As of right now, especially in rural areas, local governments have a hard task of balancing pushback while getting the most accurate, evidence-based, neutral information to make decisions. That balance can be contentious.
What is the federal government doing on data center policy? How is the Trump administration approaching it?
A few things there. In the early days, the drive was for AI expansion and to be competitive with foreign adversaries. Now due to the amount of public pushback in red and blue localities and a more cautious approach.
I’m not seeing a lot of actual policy movement at this time.
I know the EPA is looking at the chemicals used in cooling data centers because when that water is cycled through the system, some of it is discharged into the water system, so they’re looking at the Toxic Substances and Control Act for monitoring that.
How much of an impact does this minimal federal role have on industry behavior?
Y’know, this isn’t specific to data centers. This is true for all kinds of large-scale development: there’s a need to require some sort of federal monitoring and regulation.
That’s where I see an emerging role for public health. At the federal level, there could be policy movement towards requiring some sort of environmental monitoring at data centers to make sure they’re operating responsibility. Looking at specific water use relative to water availability and what happens when there’s a time of severe, persistent drought. With air quality too — we’ve seen areas where the grid isn’t as reliable so their diesel generators are kicking on more and affecting air quality for residents.
We’re just not seeing all of that right now. We need corporate disclosure.
What do you see as the most important public health impacts from data center development?
It varies by localities. The most discussed obviously is water usage. One thing I’d note about my conversations with folks enthusiastic around emerging tech is, there are still questions that need to be asked about the capacity of localities to support a data center. Like a small town in Kansas may only be using 40% of their water for their utility needs. If a data center came online, how much of that water goes to the data center?
One area underexplored within the public health discipline is energy poverty and energy security. The ability of a household to meet the needs of everything energy provides in our lives. It’s known we have an aging electric grid but we’re not talking enough about large-scale blackouts when the grid is not sufficient to support some of these new data centers.
Plus more of the week’s big development fights.
1. Laramie County, Wyoming — Meta is fighting the fine it received in the Cheyenne data center water pollution controversy, and the conflict between the tech giant and the city’s small board of public utilities is continuing to spill out into the public.
2. Niagara County, New York — This county just rejected a solar project’s highway work permits in a show of retaliation against the state’s Office of Renewable Energy Siting.
3. Barron County, Wisconsin — The anti-solar protest is the new campaign stop in deep red Wisconsin.
4. Chesapeake, Virginia — A large battery storage project on the Virginia coastline is on the rocks amidst rampant local opposition.
5. Lewis County, West Virginia — West Virginia is now a key battleground in the fight over transmission, as a line spanning all of West Virginia and Maryland — and cutting through Data Center Alley in Virginia — causes compounding consternation.
