On Redwood Materials’ milestone, states welcome geothermal, and Indian nuclear

Current conditions: Powerful winds of up to 50 miles per hour are putting the Front Range states from Wyoming to Colorado at high risk of wildfire • Temperatures are set to feel like 101 degrees Fahrenheit in Santa Fe in northern Argentina • Benin is bracing for flood flooding as thunderstorms deluge the West African nation.

New York Governor Kathy Hochul inked a partnership agreement with Ontario Premier Doug Ford on Friday to work together on establishing supply chains and best practices for deploying next-generation nuclear technology. Unlike many other states whose formal pronouncements about nuclear power are limited to as-yet-unbuilt small modular reactors, the document promised to establish “a framework for collaboration on the development of advanced nuclear technologies, including large-scale nuclear” and SMRs. Ontario’s government-owned utility just broke ground on what could be the continent’s first SMR, a 300-megawatt reactor with a traditional, water-cooled design at the Darlington nuclear plant. New York, meanwhile, has vowed to build at least 1 gigawatt of new nuclear power in the state through its government-owned New York Power Authority. Heatmap’s Matthew Zeitlin wrote about the similarities between the two state-controlled utilities back when New York announced its plans. “This first-of-its-kind agreement represents a bold step forward in our relationship and New York’s pursuit of a clean energy future,” Hochul said in a press release. “By partnering with Ontario Power Generation and its extensive nuclear experience, New York is positioning itself at the forefront of advanced nuclear technology deployment, ensuring we have safe, reliable, affordable, and carbon-free energy that will help power the jobs of tomorrow.”
Hochul is on something of a roll. She also repealed a rule that’s been on the books for nearly 140 years that provided free hookups to the gas system for new customers in the state. The so-called 100-foot-rule is a reference to how much pipe the state would subsidize. The out-of-pocket cost for builders to link to the local gas network will likely be thousands of dollars, putting the alternative of using electric heat and cooking appliances on a level playing field. “It’s simply unfair, especially when so many people are struggling right now, to expect existing utility ratepayers to foot the bill for a gas hookup at a brand new house that is not their own,” Hochul said in a statement. “I have made affordability a top priority and doing away with this 40-year-old subsidy that has outlived its purpose will help with that.”
Redwood Materials, the battery recycling startup led by Tesla cofounder J.B. Straubel, has entered into commercial production at its South Carolina facility. The first phase of the $3.5 billion plant “has brought a system online that’s capable of recovering 20,000 metric tons of critical minerals annually, which isn’t full capacity,” Sawyer Merritt, a Tesla investor, posted on X. “Redwood’s goal is to keep these resources here; recovered, refined, and redeployed for America’s advantage,” the company wrote in a blog post on its website. “This strategy turns yesterday’s imports into tomorrow’s strategic stockpile, making the U.S. stronger, more competitive, and less vulnerable to supply chains controlled by China and other foreign adversaries.”
A 13-state alliance at the National Association of State Energy Officials launched a new accelerator program Friday that’s meant to “rapidly expand geothermal power development.” The effort, led by state energy offices in Arizona, California, Colorado, Hawaii, Idaho, Louisiana, Montana, Nevada, New Mexico, Oregon, Pennsylvania, Utah, and West Virginia, “will work to establish statewide geothermal power goals and to advance policies and programs that reduce project costs, address regulatory barriers, and speed the deployment of reliable, firm, flexible power to the grid.” Statements from governors of red and blue states highlighted the energy source’s bipartisan appeal. California Governor Gavin Newsom, a Democrat, called geothermal a key tool to “confront the climate crisis.” Idaho’s GOP Governor Brad Little, meanwhile, said geothermal power “strengthens communities, supports economic growth, and keeps our grid resilient.” If you want to review why geothermal is making a comeback, read this piece by Matthew.

Yet another pipeline is getting the greenlight. Last week, the Federal Energy Regulatory Commission approved plans for Mountain Valley’s Southgate pipeline, clearing the way for construction. The move to shorten the pipeline’s length from 75 miles down to 31 miles, while increasing the diameter of the project to 30 inches from between 16 and 23 inches, hinged on whether FERC deemed the gas conduit necessary. On Thursday, E&E News reported, FERC said the developers had demonstrated a need for the pipeline stretching from the existing Mountain Valley pipeline into North Carolina.
Last week, I told you about a bill proposed in India’s parliament to reform the country’s civil liability law and open the nuclear industry to foreign companies. In the 2010s, India passed a law designed to avoid another disaster like the 1984 Bhopal chemical leak that killed thousands but largely gave the subsidiary of the Dow Chemical Corporation that was responsible for the accident a pass on payouts to victims. As a result, virtually no foreign nuclear companies wanted to operate in India, lest an accident result in astronomical legal expenses in the country. (The one exception was Russia’s state-owned Rosatom.) In a bid to attract Western reactor companies, Indian lawmakers in both houses of parliament voted to repeal the liability provisions, NucNet reported.
The critically endangered Lesser Antillean iguana has made a stunning recovery on the tiny, uninhabited islet of Prickly Pear East near Anguilla. A population of roughly 10 breeding-aged lizards ballooned to 500 in the past five years. “Prickly Pear East has become a beacon of hope for these gorgeous lizards — and proves that when we give native wildlife the chance, they know what to do,” Jenny Daltry, Caribbean Alliance Director of nature charities Fauna & Flora and Re:wild, told Euronews.

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.
