Twenty-five years ago, computers were on the verge of destroying America’s energy system.
Or, at least, that’s what lots of smart people seemed to think.
In a 1999 Forbes article, a pair of conservative lawyers, Peter Huber and Mark Mills, warned that personal computers and the internet were about to overwhelm the fragile U.S. grid.
Information technology already devoured 8% to 13% of total U.S. power demand, Huber and Mills claimed, and that share would only rise over time. “It’s now reasonable to project,” they wrote, “that half of the electric grid will be powering the digital-Internet economy within the next decade.” (Emphasis mine.)
Over the next 18 months, investment banks including JP Morgan and Credit Suisse repeated the Forbes estimate of internet-driven power demand, advising their customers to pile into utilities and other electricity-adjacent stocks. Although it was unrelated, California’s simultaneous blackout crisis deepened the sense of panic. For a moment, experts were convinced: Data centers and computers would drain the country’s energy resources.
They could not have been more wrong. In fact, Huber and Mills had drastically mismeasured the amount of electricity used by PCs and the internet. Computing ate up perhaps 3% of total U.S. electricity in 1999, not the roughly 10% they had claimed. And instead of staring down a period of explosive growth, the U.S. electric grid was in reality facing a long stagnation. Over the next two decades, America’s electricity demand did not grow rapidly — or even, really, at all. Instead, it flatlined for the first time since World War II. The 2000s and 2010s were the first decades without “load growth,” the utility industry’s jargon for rising power demand, since perhaps the discovery of electricity itself.
Now that lull is ending — and a new wave of tech-driven concerns has overtaken the electricity industry. According to its supporters and critics alike, generative artificial intelligence like ChatGPT is about to devour huge amounts of electricity, enough to threaten the grid itself. “We still don’t appreciate the energy needs of this technology,” Sam Altman, the CEO of OpenAI, has said, arguing that the world needs a clean energy breakthrough to meet AI’s voracious energy needs. (He is investing in nuclear fusion and fission companies to meet this demand.) The Washington Post captured the zeitgeist with a recent story: America, it said, “is running out of power.”
But … is it actually? There is no question that America’s electricity demand is rising once again and that load growth, long in abeyance, has finally returned to the grid: The boom in new factories and the ongoing adoption of electric vehicles will see to that. And you shouldn’t bet against the continued growth of data centers, which have increased in size and number since the 1990s. But there is surprisingly little evidence that AI, specifically, is driving surging electricity demand. And there are big risks — for utility customers and for the planet — by treating AI-driven electricity demand as an emergency.
There is, to be clear, no shortage of predictions that AI will cause electricity demand to rise. According to a recent Reuters report, nine of the country’s 10 largest utilities are now citing the “surge” in power demand from data centers when arguing to regulators that they should build more power. Morgan Stanley projects that power use from data centers “is expected to triple globally this year,” according to the same report. The International Energy Agency more modestly — but still shockingly — suggests that electricity use from data centers, AI, and cryptocurrency could double by 2026.
These concerns have also come from environmentalists. A recent report from the Climate Action Against Disinformation Commission, a left-wing alliance of groups including Friends of the Earth and Greenpeace, warned that AI will require “massive amounts of energy and water” and called for aggressive regulation.
That report focused on the risks of an AI-addled social media public sphere, which progressives fear will be filled with climate-change-denying propaganda by AI-powered bots. But in an interview, Michael Khoo, an author of the report and a researcher at Friends of the Earth, told me that studying AI made him much more frightened about its energy use.
AI is such an power-suck that it “is causing America to run out of energy,” Khoo said. “I think that’s going to be much more disruptive than the disinformation conversation in the mid-term.” He sketched a scenario where Altman and Mark Zuckerberg can outbid ordinary households for electrons as AI proliferates across the economy. “I can see people going without power,” he said, “and there being massive social unrest.”
These predictions aren’t happening in a vacuum. At the same time that investment bankers and environmentalists have fretted over a potential electricity shortage, utilities across the South have proposed a de facto solution: a massive buildout of new natural-gas power plants.
Citing the return of load growth, utilities across the South are trying to go around normal regulatory channels and build a slew of new natural-gas-burning power plants. Across at least six states, utilities have already won — or are trying to win — permission from local governments to fast-track more than 10,000 megawatts of new gas-fired power plants so that they can meet the surge in demand.
These requests have popped up across the region, pushed by vertically integrated monopoly power companies. Georgia Power won a tentative agreement to build 1,400 new megawatts of gas capacity, Canary reported. In the Carolinas, Duke Energy has asked to build 9,000 megawatts of new gas capacity, triple what it previously requested. The Tennessee Valley Authority has plans to add 6,600 megawatts of new capacity to its grid.
This buildout is big enough to endanger the country’s climate targets. Although these utilities are also building new renewable and battery farms, and shutting down coal plants, the planned surge in carbon emissions from natural gas plants would erase the reductions from those changes, according to a Southern Environmental Law Center analysis. Duke Energy has already said that it will not meet its 2030 climate goal in order to conduct the gas expansion.
In the popular press, AI’s voracious energy demand is sometimes said to be a major driver of this planned gas boom. But evidence for that proposition is slim, and the utilities have said only that data center expansion is one of several reasons for the boom. The Southeast’s population is growing, and the region is experiencing a manufacturing renaissance, due in part to the new car, battery, and solar panel factories subsidized by Biden’s climate law. Utilities in the South also face a particular challenge coping with the coldest winter mornings because so many homes and offices use inefficient and power-hungry space heaters.
Indeed, it’s hard to talk about the drivers of load growth with any specificity — and it’s hard to know whether load growth will actually happen in all corners of the South.
Utilities compete against each other to secure big-name customers — much like local governments compete with sweetheart tax deals — so when a utility asks regulators to build more capacity, it doesn’t reveal where potentialpower demand is coming from. (In other words, it doesn’t reveal who it believes will eventually buy that power.) A company might float plans to build the same data center or factory in multiple states to shop around for the best rates, which means the same underlying gigawatts of demand may be appearing in several different utilities’ resource plans at the same time. In other words, utilities are unlikely to actually see all of the demand they’re now projecting.
Even if we did know exactly how many gigawatts of new demand each utility would see, it’s almost impossible to say how much of it is coming from AI. Utilities don’t say how much of their future projected power demand will come from planned factories versus data centers. Nor do they say what each data center does and whether it trains AI (or mines Bitcoin, which remains a far bigger energy suck).
The risk of focusing on AI, specifically, as a driver of load growth is that because it’s a hot new technology — one with national security implications, no less — it can rhetorically justify expensive emergency action that is actually not necessary at all. Utilities may very well need to build more power capacity in the years to come. But does that need constitute an emergency? Does it justify seeking special permission from their statehouses or regulators to build more gas, instead of going through the regular planning process? Is it worth accelerating approvals for new gas plants? Probably not. The real danger, in other words, is not that we’ll run out of power. It’s that we’ll build too much of the wrong kind.
At the same time, we might have been led astray by overly dire predictions of AI’s energy use. Jonathan Koomey, a researcher who studies how the internet and data centers use energy (and the namesake of Koomey’s Law) told me that many estimates of Nvidia’s most important AI chips assume that their energy use is the same as their advertised “rated” power. In reality, Nvidia chips probably use half of that amount, he said, because chipmakers engineer their chips to withstand more electricity than is necessary for safety reasons.
And this is just the current generation of chips: Nvidia’s next generation of AI-training chips, called “Blackwell,” use 25 times less energy to do the same amount of computation as the previous generation of chips.
Koomey helped defuse the last panic over energy use by showing that the estimates Huber and Mills relied on were wildly incorrect. Estimates now suggest that the internet used less than 1% of total U.S. electricity by the late 1990s, not 13% as they claimed. Those percentages stayedroughly the same through 2008, he later found, even as data centers grew and computers proliferated across the economy. That’s the same year, remember, that Huber and Mills predicted that the internet would consume half of American energy.
These bad predictions were extremely convenient. Mills was a scientific advisor to the Greening Earth Society, a fossil-fuel-industry-funded group that alleged carbon dioxide pollution would actually improve the global environment. He aimed to show that climate and environmental policy would conflict with the continued growth of the internet.
“Many electricity policy proposals are on a collision course with demand forces,” Mills said in a Greening Earth press release at the time. “While many environmentalists want to substantially reduce coal use in making electricity, there is no chance of meeting future economically-driven and Internet-accelerated electric demand without retaining and expanding the coal component.” Hence the headline of the Forbes piece: “The PCs are coming — Dig more coal.”
What makes today’s AI-induced fear frenzy different from 1999 is that the alarmed projections are not just coming from businesses and banks like Morgan Stanley, but from environmentalists like Friends of the Earth. Yet neither their estimates of near-term, AI-driven power shortages — nor the analysis from Morgan Stanley that U.S. data-center use could soon triple within a year — make sense given what we know about data centers, Koomey said. It is not logistically possible to triple data centers’ electricity use in one year. “There just aren’t enough people to build data centers, and it takes longer than a year to build a new data center anyway,” he said. “There aren’t enough generators, there aren’t enough transformers — the backlog for some equipment is 24 months. It’s a supply chain constraint.”
Look around and you might notice that we have many more servers and computers today than we did in 1999 — not to mention smartphones and tablets, which didn’t even exist then — and yet computing doesn’t devour half of American energy. It doesn’t even get close. Today, computers use 1% to 4% of total U.S. power demand, depending on which estimate you trust. That’s about the same share of total U.S. electricity demand that they used in the late 1990s and mid-2000s.
It may well be that AI devours more energy in years to come, but utilities probably do not need to deal with it by building more gas. They could install more batteries, build new power lines, or even pay some customers to reduce their electricity usage during certain peak events, such as cold winter storms.
There are some places where AI-driven energy demand could be a problem — Koomey cited Ireland and Loudon County, Virginia, as two epicenters. But even there, building more natural gas is not the sole way to cope with load growth.
“The problem with this debate is everybody is kind of right,” Daniel Tait, who researches Southern utilities for the Energy and Policy Institute, a consumer watchdog, told me. “Yes, AI will increase load a little bit, but probably not as much as you think. Yes, load is growing, but maybe not as much as you say. Yes, we do need to build stuff, but maybe not the stuff that you want.”
There are real risks if AI’s energy demands get overstated and utilities go on a gas-driven bender. The first is for the planet: Utilities might overbuild gas plants now, run them even though they’re non-economic, and blow through their climate goals.
“Utilities — especially the vertically integrated monopoles in the South — have every incentive to overstate load growth, and they have a pattern of having done that consistently,” Gudrun Thompson, a senior attorney at the Southern Environmental Law Center, told me. In 2017, the Rocky Mountain Institute, an energy think tank, found in 2017 that utilities systematically overestimated their peak demand when compiling forecasts. This makes sense: Utilities would rather build too much capacity than wind up with too little, especially when they can pass along the associated costs to rate-payers.
But the second risk is that utilities could burn through the public’s willingness to pay for grid upgrades. Over the next few years, utilities should make dozens of updates to their systems. They have to build new renewables, new batteries, and new clean 24/7 power, such as nuclear or geothermal. They will have to link their grids to their neighbors’ by building new transmission lines. All of that will be expensive, and it could require the kind of investment that raises electricity rates. But the public and politicians can accept only so many rate hikes before they rebel, and there’s a risk that utilities spend through that fuzzy budget on unnecessary and wasteful projects now, not on the projects that they’ll need in the future.
There is no question that AI will use more electricity in the years to come. But so will EVs, new factories, and other sources of demand. America is on track to use more electricity. If that becomes a crisis, it will be one of our own making.

A new subsidy for metallurgical coal won’t help Trump’s energy dominance agenda, but it would help India and China.
Crammed into the Senate’s reconciliation bill alongside more attention-grabbing measures that could cripple the renewables industry in the U.S. is a new provision to amend the Inflation Reduction Act to support metallurgical coal, allowing producers to claim the advanced manufacturing tax credit through 2029. That extension alone could be worth up to $150 million a year for the “beautiful clean coal” industry (as President Trump likes to call it), according to one lobbyist following the bill.
Putting aside the perversity of using a tax credit from a climate change bill to support coal, the provision is a strange one. The Trump administration has made support for coal one of the centerpieces of its “energy dominance” strategy, ordering coal-fired power plants to stay open and issuing a raft of executive orders to bolster the industry. President Trump at one point even suggested that the elite law firms that have signed settlements with the White House over alleged political favoritism could take on coal clients pro bono.
But metallurgical coal is not used for electricity generation, it’s used for steel-making. Moreover, most of the metallurgical coal the U.S. produces gets exported overseas. In other words, cheaper metallurgical coal would do nothing for American energy dominance, but it would help other countries pump up their production of steel, which would then compete with American producers.
The new provision “has American taxpayers pay to send metallurgical coal to China so they can make more dirty steel and dump it on the global market,” Jane Flegal, the former senior director for industrial emissions in the Biden White House, told me.
The U.S. produced 67 million short tons of metallurgical coal in 2023, according to data from the U.S. Energy Information Administration, more than three-quarters of which was shipped abroad. Looking at more recent EIA data, the U.S. exported 57 million tons of metallurgical coal through the first nine months of 2024. The largest recipient was India, the final destination for over 10 million short tons of U.S. metallurgical coal, with almost 9 million going to China. Almost 7 million short tons were exported to Brazil, and over 5 million to the Netherlands.
“Metallurgical coal accounts for approximately 10% of U.S. coal output, and nearly all of it is exported. Thermal coal produced in the United States, by contrast, mostly is consumed domestically,”according to the EIA.
The tax credit comes at a trying time for the metallurgical coal sector. After export prices spiked at $344 per short ton in the second quarter of 2022 following Russia’s invasion of Ukraine (much of Ukraine’s metallurgical coal production occurs in one of its most hotly contested regions), prices fell to $145 at the end of 2024, according to EIA data.
In their most recent quarterly reports, a number of major metallurgical coal producers told investors they wanted to reduce costs “as the industry awaits a reversal of the currently weak metallurgical coal market,” according to S&P Global Commodities Insights, citing low global demand for steel and economic uncertainty.
There was “not a whisper” of the provision before the Senate’s bill was released, according to the lobbyist, who was not authorized to speak publicly. “No one had any inkling this was coming,” they told me.
But it’s been a pleasant surprise to the metallurgical coal industry and its investors.
Alabama-based Warrior Met Coal, which exports nearly all the coal it produces, reported a loss in the first quarter of 2025,blaming “the combination of broad economic uncertainty around global trade, seasonal demand weakness, and ample spot supply is expected to result in continued pressure on steelmaking coal prices.” Its shares were up almost 6% in afternoon trading Monday.
Tennessee-based Alpha Metallurgical Resources reported a $34 million first quarter loss in May, citing “poor market conditions and economic uncertainty caused by shifting tariff and trade policies,” and said it planned to reduce capital expenditures from its previous forecast. Its shares were up almost 7%.
While environmentalists have kept a hawk’s eye on the hefty donations from the oil and gas industry to Trump and other Republicans’ campaign coffers, it appears that the coal industry is the fossil fuel sector getting specific special treatment, despite being far, far smaller. The largest coal companies are worth a few billion dollars; the largest oil and gas companies are worth a few hundred billion.
But coal is very important to a few states — and very important to Donald Trump.
The bituminous coal that has metallurgical properties tends to be mined in Appalachia, with some of the major producers and exporters based in Tennessee and Alabama, or larger companies with mining operations in West Virginia.
One of those, Alliance Resource Partners, shipped almost 6 million tons of coal overseas. Its chief executive, Joseph Craft, andhis wife, Kelly, the former ambassador to the United Nations, are generous Republican donors. Craft was a guest at the White House during the signing ceremony for the coal executive orders.
Representatives of Warrior, Alpha Metallurgical, and Alliance Resources did not respond to a requests for comment.
While coal companies and their employees tend to be loyal Republican donors, the relative small size of the industry puts its financial clout well south of the oil and gas industry, where a single donor like Continental Resources’s Harold Hamm can give over $4 million and the sector as a whole can donate $75 million. This suggests that Trump and the Senate’s attachment to coal has more to do with coal’s specific regional clout, or even the aesthetics of coal mining and burning compared to solar panels and wind turbines.
After all, anyone can donate money, but in Trump’s Washington, only one resource can be beautiful and clean.
Two former Department of Energy staffers argue from experience that severe foreign entity restrictions aren’t the way to reshore America’s clean energy supply chain.
The latest version of Congress’s “One Big, Beautiful Bill” claims to be tough on China. Instead, it penalizes American energy developers and hands China the keys to dominate 21st century energy supply chains and energy-intensive industries like AI.
Republicans are on the verge of enacting a convoluted maze of “foreign entity” restrictions and penalties on U.S. manufacturers and energy companies in the name of excising China from U.S. energy supply chains. We share this goal to end U.S. reliance on Chinese minerals and manufacturing. While at the U.S. Department of Energy and the White House, we worked on numerous efforts to combat China’s grip on energy supply chains. That included developing tough, nuanced and, importantly, workable rules to restrict tax credit eligibility for electric vehicles made using materials from China or Chinese entities — rules that quickly began to shift supply chains away from China and toward the U.S. and our allies.
That experience tells us that the rules in the Republican bill will have the opposite effect. In reality, they will make it much more difficult for U.S. companies to move supply chains away from Chinese control. The GOP’s proposed restrictions require every developer of a critical minerals project, advanced manufacturing facility, or clean energy power plant to sift through their supply chains and contracts for any relationship with a Chinese (or Russian, Iranian, or North Korean) entity. Using a Chinese technology license, or too many subcomponents, or materials produced in China — even if there are few or no alternatives — would be enough to render a company ineligible for the very incentives they need to finance and build new U.S. energy production or manufacturing facilities.
This would put companies in the position of having to prove the absence of Chinese entanglements (and guarantee that there will be none in the future) to qualify for tax credits, an all but impossible task, particularly given the untested set of new rules. Huge portions of the supply chain have flowed through China for decades, including 65% of global lithium processing and 97% of solar wafer manufacturing. American companies are already working to distance themselves from Chinese expertise and components, but the complex, commingled nature of global supply chains and corporate business structures make it infeasible to flip the switch overnight.
On top of that, the latest version of the bill would impose a brand new tax on any new solar and wind projects that have too much foreign entity “assistance,” while providing the Treasury Secretary carte blanche for determining what that might be. The result: An impossible bind, whereby the very sectors that need the most support to disentangle from China are now the ones most penalized by the new Republican “foreign entity” restrictions.
The fact is that China is ahead, not behind, in many energy sectors, and America desperately needs help playing catch-up. Ford’s CEO has called Chinese battery and electric vehicle technologies “an existential threat” to U.S. automaking. In energy supply chains for nuclear, solar, batteries, and critical minerals, China is not merely producing cheap knockoffs of American inventions, it is churning outcutting-edge battery chemistries, advancedmanufacturing processes, and high-speedcharging systems, all at lower cost. And at least until the Inflation Reduction Act enacted incentives for U.S. manufacturing and deployment, the gap between the U.S. and China waswidening.
These untested foreign entity rules will widen that gap once more. Since the start of the year, developers have abandoned more than $14 billion in domestic clean energy deployment and manufacturing projects, citing the uncertain tariff and tax policy environment, and that was before the new tax on solar and wind. New analysis from Energy Innovation finds that the latest version of the bill would reduce U.S. generation capacity by 300 gigawatts over the next decade — multiple times what we will need to power new data centers for artificial intelligence. Stopping clean energy projects in their tracks is also likely to trigger an energy price shock by constraining the very energy technologies that can be built most quickly. In the end we will cede not only our supply chains to China, but also our competitive edge in the race for AI and manufacturing dominance.
Fortunately, we have all the ingredients in this country already to achieve energy leadership. The U.S. boasts deep capital markets, a highly skilled manufacturing and construction workforce, a strong consumer economy driving demand, and, in spite of recent attacks, the world’s greatest universities and national labs. We simply need policy to provide a workable path for companies to invest with certainty, bring factories back to the United States, hire American workers, and learn to produce these technologies at scale.
With the Inflation Reduction Act’s domestic production incentives and supply chain restrictions, hundreds of companies stepped up over the past few years and made that bet, pouring billions of dollars into American supply chains. Should they be enacted, the reconciliation bill’s foreign entity rules would slam the brakes on all that activity, playing right into China’s hands.
There is a way to apply a set of carefully crafted restrictions to wean us off Chinese supply chains, but we cannot afford to saddle American energy with new taxes and red tape. If we scatter rakes across the floor for companies to step on, they will just throw up their hands and send their investments overseas, leaving us more reliant on China than before.
On taxing renewables, climate finance, and Europe’s heat wave
Current conditions: Parts of Northern California are under red flag warnings as warm air meets whipping winds • China’s southwestern Guizhou province is flooded for the second time in a week • A potential bomb cyclone is taking aim at Australia’s east coast.
Late on Friday Senate Republicans added a new tax on solar and wind projects to the budget reconciliation megabill that sent many in the industry into full-blown crisis mode. The proposal would levy a first-of-its-kind penalty on all solar and wind projects tied to the quantity of materials they source from companies with ties to China or other countries designated as adversaries by the U.S. government. “Taken together with other factors both in the bill and not, including permitting timelines and Trump’s tariffs, this tax could indefinitely undermine renewables development in America,” wrote Heatmap’s Jael Holzman. Here are a few reactions from politicians and industry insiders:
The Senate began debating the GOP’s megabill yesterday. Republican Senator Thom Tillis of North Carolina was one of two from the majority party who voted on Saturday against debating the bill. Shortly thereafter, he announced he wouldn’t run for re-election next year after President Trump threatened to back his primary challenger. On Sunday evening, Tillis took to the Senate floor to give an impassioned speech denouncing the bill’s Medicaid cuts and defending wind and solar tax credits. The Senate will resume work on the bill today with what’s known as a “vote-a-rama,” during which senators will offer and vote on amendments that could yet introduce significant changes. A final vote from the Senate on the bill is expected sometime today.
The fourth International Conference on Financing for Development kicks off today in Spain, offering world leaders an opportunity to reform the world’s financial aid systems. The conference happens once per decade. This year’s delegates have already adopted the “Sevilla Commitment,” which commits to closing the $4 trillion financing gap for global goals such as ensuring everyone has affordable and reliable energy, making cities sustainable, and mobilizing $100 billion in climate mitigation funding each year toward developing countries. As Reuters explained, the text focuses on helping poor nations pay for adaptation through debt swaps, potential pollution taxes, and other creative funding mechanisms. More than 70 world leaders will be there, as will World Bank President Ajay Banga and representatives from the Gates Foundation. The U.S. government will not have a representative at the talks. The Trump administration withdrew after trying and failing to remove any mention of “climate” and “sustainability” from the conference’s draft text. Some sources told Reuters the event could be more successful without the U.S. there to “water down objectives.”
The European Union is considering changing its climate law to allow countries to lean on international carbon credits to reach emissions targets. The original goal was to cut direct emissions by 90% by 2040 compared to 1990 levels, but some countries have pushed back on that ambition, citing costs. A draft of the proposed change shows that the European Commission would allow high-quality carbon credits to account for 3% of the emissions cut starting in 2036. As Politico explains: “Such credits will allow the EU to pay for emissions-slashing projects in other, usually poorer countries, and count the resulting greenhouse gas reductions toward its own 2040 target, rather than the climate goals of the country hosting the project.” Accounting for 6% of global greenhouse gas emissions, the EU ranks fourth on the list of highest polluters, behind China, the U.S., and India.
Meanwhile, Europe is facing a punishing early-summer heat wave that is already smashing records and triggering weather alerts. A few numbers:
Nearly a third of the citizens of the Pacific island nation of Tuvalu have applied for the world’s first climate visa, which would allow them to permanently migrate to Australia.
