His intellectual influences include longtime climate action skeptics — and Bill Gates’ favorite author.

Donald Trump’s nominee for Secretary of Energy, Chris Wright, is a nerd — and he’ll tell you about it. “I’m Chris Wright, and my short bio is, I started out as a science geek, I transitioned to a tech nerd, and then I’ve been an energy entrepreneur my whole life,” he told energy journalist Robert Bryce on the Power Hungry podcast in 2020. “In addition to an energy nerd, I’ve been a climate nerd for quite some time,” he said in a talk hosted by Veriten, the energy consulting firm in 2023.
This is a far cry from Trump’s first Energy Secretary, the former Texas Governor Rick Perry, who famously failed to remember on the Republican primary debate stage the third of the three agencies he sought to eliminate (it was the Department of Energy) and who reportedly didn’t know that the Energy Department’s responsibilities — and budget — then lay heavily with maintaining the country’s nuclear stockpile.
But Wright’s extensive energy experience — studying nuclear fusion at the Massachusetts Institute of Technology and working early in his career on solar and geothermal engineering (his company, Liberty Energy, the fracking powerhouse he founded in 2011, has invested in the next-generation geothermal company Fervo, and Wright sits on the board of the nuclear company Oklo) — has not won him any plaudits from environmental groups or Democrats who focus on climate change. After Trump announced his nomination, the Sierra Club called Wright a “climate denier who has profited off of polluting our communities and endangering our health and future.” Illinois Rep. Sean Casten, one of the House’s most vocal proponents of climate action, also called Wright a “climate denier who prioritizes the wants of energy producers over the needs of American consumers.”
Few Republicans — and certainly few high-level Trump appointees — are as conversant in climate and energy data as Wright. That may make him an even more effective advocate for Trump’s “energy dominance” strategy, built around increased production of fossil fuels and, almost certainly, fewer subsidies for clean energy and electrification.
Typically when a person gains some notoriety by coming out against immediate, large-scale climate action and restrictions on fossil fuel extraction, climate advocates try to link that person to the fossil fuel industry and its long history of deliberate and knowing climate denial. Wright’s associations, however, are perfectly straightforward: Liberty Energy fracks oil and gas in the United States and Canada on behalf of large oil companies. He thinks the company’s contribution to the good of the world consists of its producing more hydrocarbons — full stop.

Wright calls this philosophy “energy sobriety,” fully conceding that climate change is real while also diminishing the urgency of mounting a response. In seemingly countless speeches, interviews, and legislative testimonies, as well as in Liberty Energy’s annual “Bettering Human Lives” report — its version of an environmental, social, and governance review — Wright is perfectly comfortable acknowledging climate change while also patiently assaulting many key pillars of climate policy as it’s practiced in the United States, Europe, and other countries in the developed world seeking to sharply reduce greenhouse gas emissions.
While Wright’s written and spoken record adds up to tens of thousands of words and hours of talks, it can be distilled into a few core ideas: Energy consumption makes people better off; energy access, especially in the developing world, is a greater global challenge than climate change; and existing alternatives to hydrocarbons are not capable of replacing the status quo energy system, which still overwhelmingly relies on fossil fuels, with little prospect of a rapid transition.
He cites a wide range of thinkers, including members of a group of scholars — including the Danish political scientist Bjorn Lomborg (whose book, False Alarm, is “fantastic,” Wright said in a Liberty talk), University of Colorado science policy scholar Roger Pielke, Jr. (“a real intellectual”), and the Canadian energy scholar and historian Vaclav Smil (“the greatest energy scholar of my lifetime by far”) — who share elements of this deflationary view of climate change.
Lomborg and Pielke have long been bêtes noires of the climate movement, mostly as the subjects of years of furious back and forth in every form of media for the past two-plus decades. (Though in Pielke’s case, there was also an investigation in 2015 over alleged conflicts of interest led by House Democrat Raul Grijalva, who is retiring from Congress this year.) Lomborg has for decades argued that climate change ranks relatively low on global challenges compared to, say, global public health, while Pielke contends that many climate change policy advocates overstate what the Intergovernmental Panel on Climate Change actually says about the connection between climate change and extreme weather, a point that has made him the object of intense criticism for going on 15 years.
Smil, meanwhile, is deeply skeptical of any effort to wean the world from fossil fuels considering their role in the production of steel, cement, plastics, and fertilizers — the materials that he describes as essential to the modern world. Smil also counts among his fans Bill Gates (“Vaclav Smil is my favorite author”), who is also one of the biggest funders and promoters of climate action through his research and investment group Breakthrough Energy and funding for companies like TerraPower, which is currently building the country’s first next-generation nuclear facility in Wyoming.
Pielke called both Wright and Doug Burgum, Trump’s nominee for Secretary of the Interior and the designated head of a planned National Energy Council “super competent. They know energy, and that’s a fantastic starting point,” he told me.
“There is polarization of the climate debate, and the idea that fossil fuels are evil and the fossil industry are arch-villains — that’s part of the framing from the progressive left about how climate wars are to be fought,” Pielke said. “I’m not particularly wedded to that sort of Manichean evil vs. good framing of the debate.”
But the differences are real. Wright strongly contests much of what is the mainstream of climate policy. While he acknowledges that increased concentrations of carbon dioxide cause higher temperature, he says it’s “actually sort of slow-moving in our lifetimes” and a “relatively modest phenomenon that’s just been wildly abused for political reasons,” he said in a talk to the conservative policy group American Legislative Exchange Council.
While the Department of Energy has only limited authority over energy policy, per se, especially the permitting and public lands issues that typically concern fossil fuel companies, Wright does have some levers he can pull. He will likely act quickly to approve more export facilities for liquified natural gas, though the Energy Department’s recently released study of LNG’s long-term effects — particularly on domestic energy prices — may complicate that somewhat. Beyond that, he will inherit a massive energy research portfolio through the national labs, putting him in charge of developing the energy technology that he says are currently insufficient to replace oil and gas.
“I’ve worked on alternatives. I’d love it if fusion energy arrives,” Wright said in an interview with the conservative website Power Line. “I love energy technology, and I think there’s good things going on, but it’s now become political.”
He believes that reaching net zero greenhouse gas emissions by 2050 is “neither achievable nor humane,” he wrote in the foreword to the 2024 edition of “Bettering Human Lives.” He also disagrees with the idea of subsidizing the world’s predominant forms of alternative energy, solar and wind.
“Wind and solar are never going to be dominant sources of energy in the world,” Wright told Bryce on the 2020 podcast. The “main impact” of subsidies for wind and solar, Wright said in another 2023 podcast episode with Bryce, “is just to make our electricity grids less reliable and electricity prices more expensive, and to do nothing for the demand for oil and very little for the demand for natural gas.”
“Oil and gas make the world go round,” he added. “[People] want higher quality of lives. That’s what drives the demand for oil and gas.”
Bryce, a persistent critic of green energy policies, told me in an email that he thinks Wright is “the right person for the DOE. He’s not apologetic about being an energy humanist. Regardless of what anyone thinks about climate change, it is obvious that we are going to need a lot more energy in the future, and the majority of that new supply will come from hydrocarbons.”
While Wright’s arguments certainly have wide purchase among his peers in the energy industry executive corps, he nevertheless stands out from the rest for his willingness to express them. In contrast to the stance taken by large, multinational energy companies, which are willing at least to pay lip service to carbon reduction goals and have, at times, embraced branding and marketing strategies to make them seem like something other than oil and gas companies (e.g. ExxonMobil’s algae-based fuel initiative and BP’s notorious “Beyond Petroleum” campaign), Wright and his company see their contribution to a better world as their work extracting oil and gas.
Other executives “don’t want to deal with the criticism that will come with taking a higher-profile stance,” Bryce told me. “They don’t have time or the inclination. It takes a lot of time, courage, and conviction to engage with the media, get on the speaking circuit, and do so in a thoughtful way.”
Wright’s emphasis on the energy poverty faced by poor countries could potentially serve as a diplomatic bridge to the developing world, especially in Africa, where some observers think there’s space for the United States to start funding natural gas development through the International Development Finance Corporation. For Wright, expanding energy production — and specifically fossil fuel development — is crucial to providing cheap energy to the developing world. He mentions in almost every talk the billions of people who use wood, dung, or other biofuels on open fires to cook indoors, causing 3 million premature deaths per year.
“The biggest problem today is a third of humanity doesn’t have hydrocarbons,” Wright told Bryce in 2023. In a 2023 speech to the American Conservation Coalition, a conservative environmental group, he described strictures against financing fossil fuel development as “not just ignorant or bad policy” but “immoral.” His solution: distributing propane stoves as widely as possible, in part through his Bettering Human Lives Foundation.
Here might be the greatest challenge for advocates of climate action: Even if most of the world’s leaders have accepted the reality of anthropogenic climate change, much of the world, especially outside North America and Europe, is still eagerly increasing its use of fossil fuels. In the United States, coal plant shutdowns are being pushed out further and natural gas investment may soon pick up again to power new demand for electricity. Globally, coal use is set to grow over the next few years. That’s thanks in large part to demand from China, the world’s largest emitter and second-largest cumulative emitter behind the United States, defying predictions that demand there was near peaking. The biggest new source of oil demand is India, a country with a per-capita gross domestic product less than 1/30th of the United States.
And so the greatest danger to aggressive action to lower global emissions may not be Chris Wright and his “sober” ideas at the helm of the Department of Energy. It may be that much of the world agrees with him.

BAAJA would likely help speed up the U.S. transmission buildout, but there’s a chance we’re undercounting the benefits.
This is Heatmap Daily, a weekday digest written by our executive editor. Subscribe here.
As you may have seen, my colleague Emily Pontecorvo and I got the first look at the Rhodium Group’s analysis of what the bipartisan permitting bill will do to emissions.
You can read our story at Heatmap. The upshot is that the bill’s most significant provisions are likely neutral for climate change in a worst-case scenario — and could, in more optimistic scenarios, help reduce emissions. (Those scenarios aren’t about how the bill will be interpreted, to be clear, but about what might happen in the broader energy economy — with economic growth, for instance, or oil prices — that will feed back into the emissions math.)
I won’t give away much more about our story, but there is one irony I want to note about the Rhodium study and the broader morass of American electricity policy. One of the Rhodium study’s big findings is that BAAJA will help expand the transmission system. Power lines are essential for decarbonization because they move electricity from the country’s sunniest and windiest places to its cities, towns, and suburbs.
BAAJA will help transmission both because the law affirmatively expands the power grid and because the bill’s changes to environmental review law could help power lines. Today, for instance, it takes twice as long on average to conduct a federal environmental impact study for transmission lines as it does for pipelines, according to Rhodium data. All in all, the Rhodium analysis estimates BAAJA could increase the amount of new transmission capacity added per year by 167% to 262% nationwide, compared to the average rate over the past decade.
Which is very interesting. But it’s worth noting that the Rhodium analysis may — emphasis on may — undercount the bill’s transmission benefits. This is because the Rhodium authors did not have time to conduct a full network study of the U.S. transmission system, which would take into effect the grid’s physical footprint, power flows, and existing bottlenecks. Instead, they looked at power supply and demand within the context of the broader U.S. energy system.
That’s a reasonable decision; indeed, it was probably the only decision they could make. Because of how energy system models work, a more fulsome analysis might have taken weeks to complete, not to mention a very large amount of money and computational power. When the National Renewable Energy Lab studied how quickly Los Angeles could switch to 100% renewable energy earlier this decade, for instance, it ran such a study, modeling every transmission line and substation in LA. Its supercomputer wound up churning through more than 100 million simulations; the research effort took three years. If the Rhodium analysts had done even a fraction as much work to examine what BAAJA would mean for the country’s power grid, then they would have of course finished their analysis well after the window to vote on BAAJA would have closed.
One of the ironies here is that while the LA 100 study was particularly exhaustive, we actually require clean energy projects to conduct similar studies all the time. Right now, one of the primary reasons it takes so long to hook up a new power plant to the grid is that it has to undergo an interconnection study in many parts of the country. In those regions, a new solar farm or battery project can’t connect to the grid until operators study its effect on grid congestion everywhere else.
As it happens, BAAJA aims to fix this process, allowing power plants to join the grid in batches.
I want to note the irony that a process we mandate for the power sector is actually too slow to deliver speedy policy analysis to legislators. If Rhodium had tried to study BAAJA the way we make power plants study the grid, then it never would have delivered its verdict in time. If you think Congress is slow, in other words, you should meet the electricity sector.
Current conditions: The Pineapple Express, an atmospheric river originating in the Pacific near Hawaii, is arriving in the Southwest laden with heavy rain that’s set to flood the region • Indonesia has the worst air quality in the world as forest fires rage along Sumatra’s southern coast • A cross-country storm will soak much of the United States on Tuesday’s Election Day.
The Senate’s grand compromise to simplify federal permitting on energy projects would likely drop emissions slightly as the benefits to accelerating deployments of clean energy infrastructure outweigh the boost the legislation could give to fossil fuels. Even under the worst-case scenario, emissions remain on the same trajectory as today. That’s according to a hotly anticipated new analysis by the Rhodium Group, the consultancy whose U.S. emissions estimates are among the most widely cited in American politics. The report, shared first with my colleague Emily Pontecorvo, found that provisions in the Bipartisan American Affordability and Jobs Act largely counteract each other on climate. The bill makes building transmission lines much easier, a key step to patching more renewables onto the grid. But it also makes new gas pipelines simpler to permit, clearing the way for a buildout of the infrastructure for the fossil fuel already dominating U.S. electricity and heating systems. Still, under the best-case scenario, the legislation could cut U.S. economy-wide emissions by 5% below where they would otherwise go in 2040. The bill could also slash energy bills by $78 per year and support construction of more than 200 gigawatts of clean energy capacity, as compared to a world where it didn’t pass. The Rhodium report is at least the second analysis yet to find that the bill could modestly lower emissions. The first, as I reported last week, came from the think tank Resources for the Future, which saw a slight drop in power-sector emissions relative to a world without BAAJA.
If overhauling national permitting rules to make building green energy infrastructure easier doesn’t work to lower emissions, traditional negotiations in favor of regulations that can deliver cuts looks no more promising. Two weeks of United Nations-led talks in Armenia ended Saturday without a settled approach to meeting 2030 deadlines for preserving more nature. “We don’t need to spend more to close the biodiversity funding gap, we need to spend better,” Marina Von Weissenberg, a Finnish senior ministerial advisor, said in a statement. “Governments have a real opportunity here to reshape public spending with future generations in mind, but they can’t do it alone. International coordination is key to giving governments the confidence to lead change.”
Last week, my colleague Katie Brigham published a detailed feature highlighting China’s tightening grip over the global supply chain for electrolyzers, the technology that zaps water with electricity to separate the molecule’s hydrogen from its oxygen and harvest the former as fuel. Keen readers of this newsletter recognize the story. Even before the Iran War, China had beefed up its public support for green hydrogen and related technologies. After the conflict constricted the flow of oil through the Strait of Hormuz, the People’s Republic redoubled its efforts. Quite literally. New data from the National Energy Administration shows that investments into the hydrogen industry doubled in the first nine months of this year, according to Hydrogen Insight.
Fermi America went public in a gangbusters initial public offering last year as the company, with a board of directors including former Texas governor and U.S. Secretary of Energy Rick Perry, pledged to build the world’s largest data center and power the facility with gas and four large-scale Westinghouse AP1000 nuclear reactors. In April, the chief executive and chief financial officer quit. The board room drama continued into the next month. The company’s stock recovered somewhat over the summer as investors bet on a turnaround pegged to a series of deals with companies looking to lease space on its future servers. But fresh chaos enveloped the startup Friday when The Texas Tribune reported that Perry had failed to earn enough support from the board of directors to win reelection to his seat.
In a statement posted to X on Friday evening, Fermi said that neither Perry nor investor Jeffrey Stein had been removed from the company’s board. “In fact, both Governor Perry and Jeffrey Stein received a majority of the votes cast by shareholders,” the statement read. “Let’s be clear: Governor Perry and Mr. Stein remain members of Fermi’s Board of Directors and will continue serving until their successors are duly elected. Both remain eligible for reelection.”

If you thought the fine particulate matter from last year’s catastrophic Los Angeles firestorm was bad, you weren’t thinking imaginatively enough about just how dangerous all that airborne material could be. A new study published in the journal Science Advances suggests that upward of 7 million people were exposed to high levels of airborne lead and other toxic metals released when homes and vehicles caught flame. The January 2025 Eaton inferno that destroyed more than 9,400 buildings and killed 19 people spewed 80 times the normal concentration of lead found in the atmosphere through a plume that settled over 70% of the Los Angeles metropolitan area. “I can envision that in the future we have these evacuation zones for smoke exposure as well,” Haroula Baliaka, the study’s lead author, who was a PhD candidate at Caltech last year, told Bloomberg. “Unfortunately, this is not a one-time event. It’s a new reality and we need to adapt to it and we need to do it sooner rather than later.”
The findings come a week after a study published in JAMA Pediatrics showed a link between wildfire smoke exposure during pregnancy and autism diagnoses in children. The research from Rutgers University examined 893,212 mother-child pairs enrolled in Medicaid, with children born between 2007 and 2014. Each increase of 0.75 micrograms per cubic meter in average concentrations of wildfire-related air pollution during pregnancy was associated with a 30% higher risk of a subsequent autism diagnosis. Exposure in the second and third trimesters had the highest risk. “Wildfire smoke can travel far beyond the communities where fires are burning, and exposure may occur even when smoke is not visible,” Stefania Papatheodorou, an epidemiologist at the Rutgers School of Public Health and lead author of the study, said in a press release. “Our findings highlight the importance of awareness of wildfire events and their potential effects on air quality during pregnancy.”
The United Kingdom is building out more than 10 gigawatts of offshore wind as London looks to shore up its electricity supplies amid the global energy shock. But Chancellor of the Exchequer John Healey said he would veto any offshore wind projects that don’t lower bills. While clean power is “how we break the grip of international gas prices on our bills,” he said the infrastructure “has to come at the right pace, in the right places, with the grid to carry it.” The statement fueled what The Guardian called “concerns that the government is moving away from the pro-renewables agenda.”
Meanwhile, the U.S. midterms aren’t the only election this week. In Sunday’s runoff election, Bulgaria’s pro-Russian acting President Iliana Iotova appeared to eke out a victory over the former prime minister Andrei Gyurov, a pro-Western banker. Her win unites the government with her close ally, Prime Minister Rumen Radev, ensuring stronger support for the leader’s two signature energy policies. One, a plan to build a pair of Westinghouse AP1000s at the Kozloduy nuclear plant, is scheduled to advance to the next planning stage next year. The other, the easing of sanctions on Russian uranium to ensure a supply of fuel for the plant’s existing reactors, looks likely to continue under Iotova’s friendly diplomacy with the Kremlin.
William Nordhaus, the pioneering Yale University economist who won the Nobel Prize in 2018 for integrating climate change into macroeconomic analysis, has died at 85 following a battle with an aggressive form of brain cancer. His nephew, Ted Nordhaus of the Breakthrough Institute, referred to his father, Robert Nordhaus, as “the original environmental lawyer and Bill as the original environmental economist,” he wrote in a blog post after his uncle’s passing. “It is safe to say that the Nordhaus brothers were doing environmental law and economics, respectively, long before either label existed. Not bad for two kids who grew up in the intellectual hotbed of Albuquerque, New Mexico, population 40,000, during and after the second world war.” Their legacies are something of the Nordhaus family brand: Pragmatism. May his memory be a blessing.
Even in the worst-case scenario, BAAJA wouldn’t increase emissions, an analysis by the Rhodium Group concludes.
The bipartisan permitting reform bill is likely to slightly cut greenhouse gas emissions and lower electricity bills by 2040 — or at worst leave emissions on the same trajectory that they are on today — as compared to the status quo, according to a new analysis of many of its provisions by the Rhodium Group, an independent research firm.
The analysis examines the policies in the Bipartisan American Affordability and Jobs Act, or BAAJA, that would have the most-clear cut effects on climate pollution and the energy system. It is the most comprehensive account of the bill’s effects on emissions so far, although it does not examine all of its provisions.
The bill is hard to analyze because — unlike recent partisan energy bills, such as the Inflation Reduction Act or President Trump’s tax and spending bill — its effects on the climate are more ambiguous and often seem to counteract each other. BAAJA will make it easier to build not only long-distance transmission lines, which are essential for clean energy, but also natural gas pipelines, which can expand fossil fuel production.
Yet the climate benefits likely outweigh or balance out the harms, at least among the studied policies, the report finds. In the best case scenario, the bill could cut U.S. economy-wide emissions by 4%, reduce energy bills by $78 per year, and drive more than 200 gigawatts of new clean energy capacity by 2040, compared to status quo policy. In a worst case scenario, greenhouse gas emissions would remain unchanged on their current trajectory.
The results should be viewed as more directionally instructive than a precise accounting of the legislation, Ben King, an energy and climate director at Rhodium, told me.
“We don’t see emissions increasing because of the bill,” King said. “This bill should drive some emission reductions, it should drive some more clean energy on the grid, and it should drive electricity bills down. And given the complexity of the bill, that’s what we can say at this point.”
The analysis does not look at the bill’s permitting certainty provisions, which Democrats initially sought to stop President Trump’s war on wind but have become one of its thorniest sections. Rhodium’s modeling is also a crude tool for assessing transmission policy, since the model can look only at economic inputs such as supply and demand, and not the physical reality of the U.S. grid, such as where transmission lines run or where the bottlenecks are.
It is the second analysis to find that the bill could modestly lower carbon pollution. A more limited report focusing only on the power grid, published last week by the think tank Resources for the Future, found the legislation could cut electricity emissions by 6% while reducing electricity system costs by $350 billion through 2050.
The effects of the bill may sound small, but BAAJA is not a climate bill. It’s not engineered to reduce reliance on fossil fuels or boost clean energy technologies. Its overarching purpose is to address various federal bottlenecks that bog down America’s ability to build stuff, whether that’s a pipeline or a highway or a power line or a solar farm. So it’s not entirely surprising that it’s not expected to have a dramatic effect on emissions.
The reason it’s a priority for Senate climate champions is that many of its provisions are important precursors to decarbonizing the U.S. economy more quickly. By enabling faster expansion of the power grid, the bill would put the country in a much better position to transition to clean energy. After Joe Biden’s big climate bill, the Inflation Reduction Act, passed in 2022, Princeton University researchers found that the country’s slow buildout of transmission lines would be a major obstacle to gleaning the law’s benefits. Unless the country more than doubled the rate of transmission expansion, they wrote, more than 80% of the IRA’s emission reduction potential by 2030 would be lost.
BAAJA could nearly triple the build rate of high-voltage transmission, the Rhodium Group found, from an average of about 0.7 terawatt-miles added per year over the past decade to an average annual pace of 1.9 to 2.6 terawatt-miles through 2040. Because Republicans and President Trump have repealed so many of the IRA’s provisions, this won’t drive as much clean energy as the Princeton researchers expected, but Rhodium estimates that by 2040, BAAJA would help between 17 and 249 gigawatts of clean resources get built compared to a world without it.
The growing grid is the main reason why the bill cuts energy costs, because it enables more lower-cost resources to connect to the grid. The bill’s requirement that data centers pay the full cost of connecting to the grid also puts downward pressure on electricity rates.
“If your goal is to do climate policy in the future, this is an important down payment to making progress there,” King said.
The authors studied the bill’s provisions under a range of economic assumptions, including a “best case” scenario in which clean energy gets cheaper and easily outcompetes natural gas, and a “worst case” scenario where natural gas prices collapse and the inexpensive fuel keeps dominating the U.S. energy system.

The authors limited their analysis to the bill’s provisions that speed up transmission line and natural gas pipeline permitting. They assumed that when you make it easier to approve transmission lines, the lines get cheaper to build and get built more quickly. The same goes for gas pipelines. Then they looked at how the energy system would respond. Would we build more power plants? Would there be more natural gas production? Where will that gas go?
The caveats, aside from omitting the bill’s “project certainty” provisions, are that they did not account for policies that support geothermal energy, virtual power plants, advanced transmission technologies, or the ways in which the bill would reduce congestion on the grid — all of which could result in fewer emissions. At the same time, the modeling assumes that all of the data centers that get built between now and 2040 connect to the grid, even though today, many data centers are planning to run on inefficient off-grid natural gas plants. That means this modeling likely underestimates emissions from data centers. (Although the authors did a separate exercise that went deeper into data centers, which I’ll explain shortly.)
The report also limited its analysis to the United States. While the modeling found that liquified natural gas exports would increase by 8% to 15% under BAAJA, the authors did not account for how those exports could affect the energy mix or emissions in the rest of the world.
They found that the bill’s changes to the Clean Water Act and the National Environmental Policy Act would enable more gas pipeline development, which, in isolation, would increase emissions relative to a world without BAAJA. More pipelines means more production of oil and natural gas, which means higher methane and CO2 emissions throughout the fossil supply chain. Under a worst case scenario, they estimate a 4% increase in the amount of new gas capacity, although gas-fired generation as a whole increases by less than 1% in 2040. Even then, emissions would simply be flat compared to current expectations.
“On net, the emissions increases that we see there are outweighed by the emissions benefits that come from the transmission provisions of the bill,” King said.
The report also studied how BAAJA might affect data center emissions. Its “base case” scenario — which includes all the analysis I’ve shared with you so far — assumes data centers will make up about 17% of electricity demand by 2040. That figure already supposes huge growth in data center energy consumption, because data centers only use about 5% of U.S. electricity today.
But what if data center demand grows even faster than that? The authors modeled two additional scenarios to see what would happen if data center electricity demand instead accounted for more than a quarter of U.S. electricity demand in 2040.
While BAAJA would make it easier for data centers to connect to the grid, it also includes ratepayer protection provisions that would make it more expensive to do so — roughly 10% more for a 1 gigawatt data center, Rhodium estimates. Determining whether that will drive developers on-grid or off-grid was beyond the scope of the analysis, so the modelers looked at the two extremes — a world where all additional data center demand hooks up to the grid and one where none of it does.
For the on-grid scenario, whether or not that additional demand is met with mostly gas plants or cleaner sources largely depends on the price of fossil versus clean generation. But even if most of the demand was met by natural gas plants on the grid, emissions would still be 30% lower than if it was met by natural gas plants off the grid, Rhodium found.
