On the looming climate summit, clean energy stocks, and Hurricane Rafael

Current conditions: A winter storm could bring up to 4 feet of snow to parts of Colorado and New Mexico • At least 89 people are still missing from extreme flooding in Spain • The Mountain Fire in Southern California has consumed 14,000 acres and is zero percent contained.
The world is still reeling from the results of this week’s U.S. presidential election, and everyone is trying to get some idea of what a second Trump term means for policy – both at home and abroad. Perhaps most immediately, Trump’s election is “set to cast a pall over the UN COP29 summit next week,” said the Financial Times. Already many world leaders and business executives have said they will not attend the climate talks in Azerbaijan, where countries will aim to set a new goal for climate finance. “The U.S., as the world’s richest country and key shareholder in international financial institutions, is viewed as crucial to that goal,” the FT added.
Trump has called climate change a hoax, vowed to once again remove the U.S. from the Paris Agreement, and promised to stop U.S. climate finance contributions. He has also promised to “drill, baby, drill.” Yesterday President Biden put new environmental limitations on an oil-and-gas lease sale in Alaska’s Arctic National Wildlife Refuge. The lease sale was originally required by law in 2017 by Trump himself, and Biden is trying to “narrow” the lease sale without breaking that law, according to The Washington Post. “The election results have made the threat to America's Arctic clear,” Kristen Miller, executive director of Alaska Wilderness League, told Reuters. “The fight to save the Arctic Refuge is back, and we are ready for the next four years.”
Another early effect of the decisive election result is that clean energy stocks are down. The iShares Global Clean Energy exchange traded fund, whose biggest holdings are the solar panel company First Solar and the Spanish utility and renewables developer Iberdola, is down about 6%. The iShares U.S. Energy ETF, meanwhile, whose largest holdings are Exxon and Chevron, is up over 3%. Some specific publicly traded clean energy stocks have sunk, especially residential solar companies like Sunrun, which is down about 30% compared to Tuesday. “That renewables companies are falling more than fossil energy companies are rising, however, indicates that the market is not expecting a Trump White House to do much to improve oil and gas profitability or production, which has actually increased in the Biden years thanks to the spikes in energy prices following the Russian invasion of Ukraine and continued exploitation of America’s oil and gas resources through hydraulic fracturing,” wrote Heatmap’s Matthew Zeitlin.
Hurricane Rafael swept through Cuba yesterday as a Category 3 storm, knocking out the power grid and leaving 10 million people without electricity. Widespread flooding is reported. The island was still recovering from last month’s Hurricane Oscar, which left at least six people dead. The electrical grid – run by oil-fired power plants – has collapsed several times over the last few weeks. Meanwhile, the U.S. Bureau of Safety and Environmental Enforcement said yesterday that about 17% of crude oil production and 7% of natural gas output in the Gulf of Mexico was shut down because of Rafael.
It is “virtually certain” that 2024 will be the warmest year on record, according to the European Copernicus Climate Change Service. In October, the global average surface air temperature was about 60 degrees Fahrenheit, or nearly 3 degrees Fahrenheit warmer than pre-industrial averages for that month. This year is also on track to be the first entire calendar year in which temperatures are more than 1.5 degrees Celsius above pre-industrial levels. “This marks a new milestone in global temperature records and should serve as a catalyst to raise ambition for the upcoming climate change conference,” said Copernicus deputy director Dr. Samantha Burgess.

The world is falling short of its goal to double the rate of energy efficiency improvements by 2030, the International Energy Agency said in its new Energy Efficiency 2024 report. Global primary energy intensity – which the IEA explained is a measure of efficiency – will improve by 1% this year, the same as last year. It needs to be increasing by 4% by the end of the decade to meet a goal set at last year’s COP. “Boosting energy efficiency is about getting more from everyday technologies and industrial processes for the same amount of energy input, and means more jobs, healthier cities and a range of other benefits,” the IEA said. “Improving the efficiency of buildings and vehicles, as well as in other areas, is central to clean energy transitions, since it simultaneously improves energy security, lowers energy bills for consumers and reduces greenhouse gas emissions.” The group called for more government action as well as investment in energy efficient technologies.
Deforestation in Brazil’s Amazon fell by 30.6% in the 12 months leading up to July, compared to a year earlier. It is now at the lowest levels since 2015.

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.
