A counter-proposal for the country’s energy future.
American electricity consumption is growing for the first time in generations. And though low-carbon technologies such as solar and wind have scaled impressively over the past decade, many observers are concerned that all this new demand will provide “a lifeline for more fossil fuel production,” as Senator Martin Heinrich put it.
In response, a few policy entrepreneurs have proposed novel regulations known as “additionality” requirements to handle new sources of electric load. First suggested for electrolytic hydrogen, additionality standards would require that subsidized hydrogen producers source their electricity directly from newly built low-carbon power plants; in a Heatmap piece from September, Brian Deese and Lisa Hansmann proposed similar requirements for new artificial intelligence. And while AI data centers were their focus, the two argued that additionality “is a model that can be extended to address other sectors facing growing energy demand.”
There is some merit to additionality standards, particularly for commercial customers seeking to reduce their emissions profile. But we should be skeptical of writing these requirements into policy. Strict federal additionality regulations will dampen investment in new industries and electrification, reduce the efficiency of the electrical grid through the balkanization of supply and demand, and could become weapons as rotating government officials impose their views on which sources of demand or supply are eligible for the standards. The grid and the nation need a regulatory framework for energy abundance, not burdensome additionality rules.
After decades of end-use efficiency improvements, offshoring of manufacturing, and shifts toward less material-intensive economies, a confluence of emerging factors are pushing electricity demand back up again. For one, the nation is electrifying personal vehicles, home heating, and may do the same for industrial processes like steel production in the not-too-distant future, sparked by a combination of policy and commercial investment. Hydrogen, which has long been a marginal fuel, is attractingsubstantial interest. And technological innovation is leading to whole new sources of electric load — compute-hungry artificial intelligence beingthe most immediate example, but also large-scale critical minerals refining, indoor agriculture like alternative protein cultivation and aquaculture, and so on.
In recent years, clean energy has seemed to be on an unstoppable path toward dominating the power sector. Coal-fired generation has been in terminal decline in the United States as natural gas power plants and solar and wind farms have become more competitive. Flexible gas generation, likewise, is increasingly crowded out by renewables when the wind is blowing and the sun shining. These trends persisted in the context of stable electricity load. But even as deployment accelerates, low-carbon electricity supply may not be able to keep up with the surprisingly robust growth in demand. The most obvious — though not the exclusive — way for utilities and large corporates to meet that demand is often with new or existing natural gas capacity. Even a few coal plants have delayed retirement, reportedly in response to rising demand and reliability concerns.
Given the durable competitiveness of coal and especially natural gas, some form of additionality requirement might make sense for hydrogen production in particular, since hydrogen is not just a nascent form of electric load but a novel fuel in its own right. Simply installing an electrolyzer at an existing coal or natural gas plant could produce hydrogen that, from a lifecycle perspective, would result in higher carbon emissions, even if it displaces fossil fuels like gas or oil in final consumption. Even so, many experts caution that overly strict additionality standards for hydrogen at this stage are overkill, and may smother the industry in its crib.
Likewise, large corporate entities and electricity customers adopting additionality requirements for their own operations can bolster investment in so-called “clean firm” generation like nuclear, geothermal, and fossil fuels with carbon capture. In just the past month, Google announced plans to back the construction of new small nuclear reactors, and Microsoft announced plans to purchase electricity for new data centers from the shuttered Three Mile Island power plant, the plant made famous by the 1979 meltdown but which only closed down in 2019. Three Mile Island’s $100-per-megawatt-hour price tag would have been unthinkable just a few years ago but is newly attractive.
Notice the problem Microsoft is trying to solve here: a lack of abundant, reliable electricity generation. Outdated technology licensing, onerous environmental permitting processes, and other regulatory barriers are obstructing the deployment of renewables, advanced nuclear energy, new enhanced geothermal technologies, and low-carbon sources. Additionality fixes none of these issues. Of course, Deese and Hansmann propose “a dedicated fast-track approval process” for verifiably additional low-carbon generation supplying new sources of AI load. Yet this should be the central effort, not the after-the-fact add-on. The back and forth over additionality rules for the clean hydrogen tax credit is a case in point. The rules for the tax credit will (likely) be finalized by January, but lawsuits already loom over them. Expanding this contentious additionality requirement to apply to broad use cases will be even more contentious without solving the actual shortage data center companies care about. Conversations about additionality are a distraction and misplace the energies of policymakers and staff.
Substituting one regulatory thicket for another is a recipe for stasis. Instead of adding more red tape, we should be working to cut through it, fast-tracking the energy transition and fostering abundance.
With such broad requirements, what’s to stop future administrations from expanding them to cover electric vehicle charging, electric arc furnace steelmaking, alternative protein production, or any politically disfavored source of new demand? Could a second Trump Administration use additionality to punish political enemies in the tech industry? Could a Harris Administration do the same? What if a future administration maintained additionality standards for new sources of load, but required that the electricity come from fossil fuels instead of low-carbon sources?
Zero-sum regulatory contracts between sources of electricity supply and demand are not simply at risk of becoming a tool for handing out favors on a partisan basis — they already are one. Two pieces of model legislation proposed at the July meeting of the American Legislative Exchange Council, an organization of conservative state legislators that collaborate to write off-the-shelf legislative measures, would require public utility commissions to prioritize dispatchable generation and formally discourage intermittent renewable sources like solar and wind. One of the proposals suggests leaning on state attorneys general to extend the lifespans of coal plants threatened with retirement.
These proposals did not move forward this year, but it is unlikely that the motivating force behind them is exhausted. And whatever one thinks of the relative merits of intermittent versus firm generation, ALEC’s proposals demonstrate just how easily gamed regulations like additionality could be and the risks of relying on administrative discretion instead of universal, pragmatic rules.
This is not how the electric grid is supposed to work. The grid is, if not an according-to-Hoyle public good, a shared public resource, providing essential services to customers large and small. Homeowners don’t have to sign additionality contracts with suppliers when they buy an electric car or replace their gas furnace with an electric heat pump. Everyone understands that such requirements would slow the pace of electrification and investment in new industries. The same holds for corporate customers and novel sources of load.
The real problem facing the AI, hydrogen, nuclear, geothermal, and renewables industries is an inability to build. There are more than enough clean generators queueing to enter the system — 2.6 terawatts at last count, according to the Lawrence Berkeley National Laboratory. The unfortunate reality, however, is that just one in five of these projects will make it through — and those represent just 14% of the capacity waiting to connect. Still, this totals about 360 gigawatts of new energy generation over the next few years, much more than the predicted demand from AI data centers. Obstacles to technology licensing, permitting, interconnection, and transmission are the key bottlenecks here.
Would foregoing additionality requirements and loosening regulatory strictures on technology licensing and permitting increase the commercial viability of new or existing fossil fuel capacity, as Deese and Hansmann warn? Perhaps, on some margin. But for the foreseeable future, the energy projects and infrastructure most burdened by regulatory requirements will be low-carbon ones. Batteries, solar, and wind projects make up more than 80% of the queue added in 2023. Meanwhile, oil and gas benefit from categorical exclusions under the National Environmental Policy Act, while low-carbon technologies are subject to stricter standards (although three permitting bills recently passed the House, including one that waives these requirements for new geothermal projects).
Consider that 40% of projects supported by the Inflation Reduction Act are caught up in delays. That is $84 billion of economic activity just waiting for the paperwork to be figured out, according to the Financial Times. Additionality requirements are additional boxes to check that almost necessarily imply additional delays. Permitting reform makes them redundant and unnecessary for a cleaner future.
This underscores perhaps the most essential conflict between strict additionality requirements and clean energy abundance. Ensuring that every new policy and every new source of demand allows for absolutely zero additional fossil fuel consumption or emissions will prove counterproductive to global decarbonization in the long run. Natural gas is still reducing emissions on the margin in the United States. Over the past decade, in years with higher natural gas prices, coal generation has ticked up, indicating that the so-called “natural gas bridge” has not yet reached its terminus. Even aggressive decarbonization scenarios now expect a substantial role for natural gas over the coming decades. And in the long term, natural gas plants may prove wholly compatible with abundant, low-carbon electricity systems if next-generation carbon capture technologies prove scalable.
The United States is the world’s energy technology R&D and demonstration laboratory. If policies to prune marginal fossil fuel consumption here stall domestic investment and scaling of low-carbon technologies — as current permitting regulations already do, and proposed additionality requirements would do — then we will not only slow U.S. decarbonization, but also inhibit our ability to export affordable and scalable low-carbon technologies abroad.
Environmental progress’s surest path is in speeding up. For that to happen, we need processes that allow for rapid deployment of clean energy solutions. Expediting technology licensing, fast-tracking federal infrastructure permitting, and finding opportunities for quicker and more rational interconnections should be first and foremost.
The real solution lies in building a regulatory environment where energy abundance can flourish. Clearing the path for clean energy development, we can achieve a future where energy is affordable, reliable, and abundant—a future where the United States leads in both decarbonization and economic growth. It’s time to stop adding barriers and start speeding up progress.

The Environmental Protection Agency just unveiled its argument against regulating greenhouse emissions from power plants.
In federal policymaking, the weight of the law can rest on a single word. When it comes to reducing planet-warming emissions from the power sector, that word is “significantly.” The Clean Air Act requires the Environmental Protection Agency to regulate any stationary source of emissions that “causes, or contributes significantly to, air pollution which may reasonably be anticipated to endanger public health or welfare.”
The EPA has considered power plants a significant source of dangerous greenhouse gases since 2015. But today, Trump’s EPA said, actually, never mind.
A proposed rule published in the Federal Register on Wednesday argues that U.S. fossil fuel-fired power plants make up “a small and decreasing part of global emissions” and therefore are not significant, and do not require regulation under the law. The rule would repeal all greenhouse gas emission standards for new and existing power plants — both the standards the Biden administration finalized last year, which have been tied up in court, as well as the standards that preceded them, which were enacted by Obama in 2015.
In a separate proposal, the EPA also took steps to repeal limits on mercury and hazardous air pollutants from coal plants that were enacted last year, reverting the standard back to one set in 2012.
The argument that U.S. power plants make up a small sliver of global emissions and thus aren’t worth addressing is like having “a five-alarm fire that could be put out if you send out all the trucks, and you don’t send any of the trucks because no one truck could put the fire out by itself,” David Doniger, a senior attorney and strategist at the Natural Resources Defense Council, told me. “We just think that is a wacky reversal and a wacky interpretation of the Clean Air Act.”
When you add up every plug, power button, and light switch across the country, electricity usage produces 25% of U.S. greenhouse gas emissions each year. Over the past 30 years, American power plants have contributed about 5% of the total climate pollution spewed into the atmosphere worldwide.
In the global context, that may sound small. But in a recent report titled “The Scale of Significance," New York University’s Institute for Policy Integrity estimated that if U.S. power plants were a country, it would be the sixth biggest emitter in the world, behind China, the European Union, India, Russia, and the remainder of U.S. emissions. The report also notes that U.S. actions on emissions make other countries more likely to follow, due to technological spillovers that reduce the cost of decarbonization globally.
In addition to the significance finding, the EPA gave two other reasons for repealing the power plant rules. It argued that “cost-effective control measures are not reasonably available,” meaning there’s no economic way to reduce emissions at the source. It also said the new administration’s priority “is to promote the public health or welfare through energy dominance and independence secured by using fossil fuels to generate power.”
The first argument is an attempt to say that Biden’s standards flouted the law. In 2022, the Supreme Court ruled that the EPA could not simply tell states to reduce emissions from the power sector, which is what the Obama administration had initially tried to do. Instead, the agency would have to develop standards that could be applied on a plant-by-plant basis — so long as those rules were “cost-reasonable” and “adequately demonstrated.”
To comply with that ruling, Biden’s EPA based its standards on the potential to install carbon capture technology that can reduce flue gas emissions by 90%. The regulations would have required existing coal plants to install carbon capture by 2039, or else shut down. (To the chagrin of many energy system observers, the administration chose not to apply limits to existing gas-fired power plants.) But while fossil fuel companies and utilities had, in the past, asserted that carbon capture was viable, they deemed the standards impossible to meet.
Trump’s EPA is now agreeing. “In 2024,” Zeldin said on Wednesday, “rules were enacted seeking to suffocate our economy in order to protect the environment, to make all sorts of industries including coal and more disappear, regulate them out of existence.”
When Trump moved to overturn Obama’s power plant regulations during his first term, his EPA did not contest the significance of the sector’s emissions, and simply enacted a weaker standard. A week before he left office, the agency also finalized a rule that set the threshold for “significance” at 3% of U.S. emissions — which exempted major polluters like refineries, but still applied to power plants.
This time, Trump has a new apparent game plan: Strip the Clean Air Act of its jurisdiction over greenhouse gases altogether. Today’s action was the first step; EPA Administrator Lee Zeldin has said the agency will similarly “reconsider” emissions rules for cars and oil and gas drilling. But the cornerstone of the plan is to reverse what’s known as the “endangerment finding” — the 2009 conclusion that greenhouse gases present a threat to public health and welfare, and therefore are one of the pollutants EPA must address under the Clean Air Act.
“The Trump administration is trying to say, don’t worry about the Clean Air Act. It will never apply, so you can go back to your old ways,” said Doniger. But if the argument that power plant emissions are insignificant is a stretch, appraising greenhouse gas emissions as benign is inconceivable, he said. “The endangerment finding was based, in 2009, on a Denali-sized mountain of evidence. Since then, it’s grown to Everest-size, so there’s no way that they would be able to put together a rational record saying the science is wrong.”
These highly technical questions of whether emissions are “significant” or whether carbon capture is “adequately demonstrated” could soon be determined by a group of people who lack both the expertise to answer them and the inclination to wade through thousands of pages of atmospheric science and chemical engineering documents: judges.
Last year, the Supreme Court overturned a long-held precedent known as Chevron deference. That ruling means that the courts are no longer required to defer to an agency’s interpretation of statute — judges must make their own determinations of whether agencies are following the intent of the law.
When environmental groups begin challenging the EPA’s repeals in court, judges are “going to be bombarded with the need to make these highly technical, nuanced decisions,” Michael Wara, a lawyer and scholar focused on climate and energy policy at Stanford University, told me. He said the reason Chevron deference was established in the first place is that judges didn’t want to be making engineering decisions about power plants. “They felt extremely uncomfortable having to make these calls.”
The conservative Supreme Court overturned the precedent because of a sense that political decisions were being dressed up in scientific reasoning. But Wara doesn’t think the courts are going to like being put back into the role of weighing technical minutia and making engineering decisions.
“It’s a past that the courts didn’t like and they tried to engineer a way out of via the Chevron doctrine,” he said. “I would expect that we’re going to see a drift back toward a doctrine that looks a little bit more Chevron-like, maybe less deference to agencies. But it’s hard to predict in the current environment what’s going to happen.”
Look more closely at today’s inflation figures and you’ll see it.
Inflation is slowing, but electricity bills are rising. While the below-expectations inflation figure reported by the Bureau of Labor Statistics Wednesday morning — the consumer price index rose by just 0.1% in May, and 2.4% on the year — has been eagerly claimed by the Trump administration as a victory over inflation, a looming increase in electricity costs could complicate that story.
Consumer electricity prices rose 0.9% in May, and are up 4.5% in the past year. And it’s quite likely price increases will accelerate through the summer, thanks to America’s largest electricity market, PJM Interconnection. Significant hikes are expected or are already happening in many PJM states, including Maryland,New Jersey,Delaware, Pennsylvania, and Ohio with some utilities having said they would raise rates as soon as this month.
This has led to scrambling by state governments, with New Jersey announcing hundreds of millions of dollars of relief to alleviate rate increases as high as 20%. Maryland convinced one utility to spread out the increase over a few months.
While the dysfunctions of PJM are distinct and well known — new capacity additions have not matched fossil fuel retirements, leading to skyrocketing payments for those generators that can promise to be on in time of need — the overall supply and demand dynamics of the electricity industry could lead to a broader price squeeze.
“Trump and JD Vance can get off tweets about how there’s no inflation, but I don’t think they’ll feel that way in a week or two,” Skanda Amarnath, executive director of Employ America, told me.
And while the consumer price index is made up of, well, almost everything people buy, electricity price increases can have a broad effect on prices in general. “Everyone relies on energy,” Amarnath said. “Businesses that have higher costs can’t just eat it.” That means higher electricity prices may be translated into higher costs throughout the economy, a phenomenon known as “cost-push inflation.”
Aside from the particular dynamics of any one electricity market, there’s likely to be pressure on electricity prices across the country from the increased demand for energy from computing and factories. “There’s a big supply adjustment that’s going to have to happen, the data center demand dynamic is coming to roost,” Amarnath said.
Jefferies Chief U.S. Economist Thomas Simons said as much in a note to clients Wednesday. “Increased stress on the electrical grid from AI data centers, electric vehicle charging, and obligations to fund infrastructure and greenification projects have forced utilities to increase prices,” he wrote.
Of course, there’s also great uncertainty about the future path of electricity policy — namely, what happens to the Inflation Reduction Act — and what that means for prices.
The research group Energy Innovation has modeled the House reconciliation bill’s impact on the economy and the energy industry. The report finds that the bill “would dramatically slow deployment of new electricity generating capacity at a time of rapidly growing electricity demand.” That would result in higher electricity and energy prices across the board, with increases in household energy spending of around $150 per year in 2030, and more than $260 per year in 2035, due in part to a 6% increase in electricity prices by 2035.
In the near term, there’s likely not much policymakers can do about electricity prices, and therefore utility bills going up. Renewables are almost certainly the fastest way to get new electrons on the grid, but the completion of even existing projects could be thrown into doubt by the House bill’s strict “foreign entity of concern” rules, which try to extricate the renewables industry from its relationship with China.
“We’re running into a set of cost-push dynamics. It’s a hairy problem that no one is really wrapping their heads around,” Amarnath said. “It’s not really mainstream yet. It’s going to be.”
In some relief to American consumers, if not the planet, while it may be more expensive for them to cool their homes, it will be less expensive to get out of them: Gasoline prices fell 2.5% in May, according to the BLS, and are down 12% on the year.
Six months in, federal agencies are still refusing to grant crucial permits to wind developers.
Federal agencies are still refusing to process permit applications for onshore wind energy facilities nearly six months into the Trump administration, putting billions in energy infrastructure investments at risk.
On Trump’s first day in office, he issued two executive orders threatening the wind energy industry – one halting solar and wind approvals for 60 days and another commanding agencies to “not issue new or renewed approvals, rights of way, permits, leases or loans” for all wind projects until the completion of a new governmental review of the entire industry. As we were first to report, the solar pause was lifted in March and multiple solar projects have since been approved by the Bureau of Land Management. In addition, I learned in March that at least some transmission for wind farms sited on private lands may have a shot at getting federal permits, so it was unclear if some arms of the government might let wind projects proceed.
However, I have learned that the wind industry’s worst fears are indeed coming to pass. The Fish and Wildlife Service, which is responsible for approving any activity impacting endangered birds, and the U.S. Army Corps of Engineers, tasked with greenlighting construction in federal wetlands, have simply stopped processing wind project permit applications after Trump’s orders – and the freeze appears immovable, unless something changes.
According to filings submitted to federal court Monday under penalty of perjury by Alliance for Clean Energy New York, at least three wind projects in the Empire State – Terra-Gen’s Prattsburgh Wind, Invenergy’s Canisteo Wind, and Apex’s Heritage Wind – have been unable to get the Army Corps or Fish and Wildlife Service to continue processing their permitting applications. In the filings, ACE NY states that land-based wind projects “cannot simply be put on a shelf for a few years until such time as the federal government may choose to resume permit review and issuance,” because “land leases expire, local permits and agreements expire, and as a result, the project must be terminated.”
While ACE NY’s filings discuss only these projects in New York, they describe the impacts as indicative of the national industry’s experience, and ACE NY’s executive director Marguerite Wells told me it is her understanding “that this is happening nationwide.”
“I can confirm that developers have conveyed to me that [the] Army Corps has stopped processing their applications specifically citing the wind ban,” Wells wrote in an email. “As I have understood it, the initial freeze covered both wind and solar projects, but the freeze was lifted for solar projects and not for wind projects.”
Lots of attention has been paid to Trump’s attacks on offshore wind, because those projects are sited entirely in federal waters. But while wind projects sited on private lands can hypothetically escape a federal review and keep sailing on through to operation, wind turbines are just so large in size that it’s hard to imagine that bird protection laws can’t apply to most of them. And that doesn’t account for wetlands, which seem to be now bedeviling multiple wind developers.
This means there’s an enormous economic risk in a six-month permitting pause, beyond impacts to future energy generation. The ACE NY filings state the impacts to New York alone represent more than $2 billion in capital investments, just in the land-based wind project pipeline, and there’s significant reason to believe other states are also experiencing similar risks. In a legal filing submitted by Democratic states challenging the executive order targeting wind, attorneys general listed at least three wind projects in Arizona – RWE’s Forged Ethic, AES’s West Camp, and Repsol’s Lava Run – as examples that may require approval from the federal government under the Bald and Golden Eagle Protection Act. As I’ve previously written, this is the same law that bird conservation advocates in Wyoming want Trump to use to reject wind proposals in their state, too.
The Fish and Wildlife Service and Army Corps of Engineers declined to comment after this story’s publication due to litigation on the matter. I also reached out to the developers involved in these projects to inquire about their commitments to these projects in light of the permitting pause. We’ll let you know if we hear back from them.
