Building new capacity isn’t always as straightforward as it sounds.
When you think of companies whose valuations are soaring due to artificial intelligence, the ones that come to mind first are probably the chip designer Nvidia, whose shares are up 180% this year, or Elon Musk’s xAI, which its investors recently valued at $50 billion.
But aside from those, some of the best performing companies of this year have been those that own or supply equipment for the power plants that generate the energy to run all that AI infrastructure in the first place.
GE Vernova’s gas turbine orders have almost doubled so far this year, chief executive Scott Strazik said in an October earnings call; since then, the company has secured orders for another nearly 9 gigawatts’ worth of turbines in the U.S., the company said in an investor presentation Tuesday. “I can’t think of a time that the gas business has had more fun than they’re having right now,” Strazik told investors. The company’s stock is up almost 150% from the end of 2023.
Vistra, which owns over 40,000 megawatts of generation assets, including around 6,500 megawatts of nuclear power plants and more than two dozen gas-fired power plants, is planning on developing 2,000 megawatts of natural gas capacity, its chief executive Jim Burke said in November; its share price is up 272% for the year. The utility Entergy, which last week signed a deal with Meta to power a planned data center in northeastern Louisiana, is up 45%. Compare those impressive results to the S&P 500, which is up a healthy but comparatively modest 27% on the year.
Much of that enthusiasm comes from huge expected increases in energy demand. Grid Strategies, an energy policy consulting firm, last week updated its forecast for energy demand growth over the next five years, raising it from an increase of 39 gigawatts as of the end of 2023 to a rise of 128 gigawatts. That works out to annual projected growth of around 3%, compared to less than 1% annual growth in the first two decades of this century.
Where will all that additional energy come from? “Quite frankly, in the next five years, we’re going to see a lot of new gas turbines being built,” Cy McGeady, a fellow at the Center for Strategic and International Studies, told me, adding that the “prospects are good for a natural gas boom.”
The data centers that are driving renewable demand tend to require a constant flow of energy at all times — except when their power demands surge — while renewables are intermittent and may be far away from planned load growth. While so-called hyperscalers such as Amazon, Meta, and Google have made deals to support the development of 24/7 clean power sources like nuclear, the most optimistic time frame for any of these new developments to start producing power is sometime in the early 2030s.
Rob Gramlich, the president of Grid Strategies, told me the technology companies generating all this demand growth typically want it satisfied with renewables, but “they really need transmission in order to do that.”
“If everyone had done this 10 years ago, we could have connected a lot of generation a lot quicker. It could have been a lot cleaner generation mix,” Gramlich told me. Now, though, even if a utility wants to build solar, wind, and storage that can provide power at costs comparable to new gas, “it’s only available as an option if you build the grid infrastructure ahead of time,” he said.
McGeady agrees. “It’s the only path forward,” he said of natural gas. “Nobody is willing to not build the next data center because of inability to access renewables.”
But therein lies the difficulty: While natural gas plants are not as transmission-dependent as renewables, some analysts worry that even gas generators won’t be able to respond quickly enough to the increase in demand.
“When we look at the hot spots of Data Center development, in the U.S. and around the world, we see a significant overlap with regions that have favorable policy support for natural gas,” Morgan Stanley analysts wrote in a note to clients. And yet, “there will in our view be a significant shortfall in available U.S. power grid access relative to the magnitude of new data centers needed to ‘absorb’ the AI equipment purchases over the next several years, with the bottleneck becoming apparent in mid-to-late 2025,” the analysts wrote.
The utilities in these areas — places like Georgia, Arizona, and North Carolina — are indeed building new natural gas capacity. In other places where the laws and regulations aren’t as favorable to gas development, however, analysts expect to see more data centers sited at existing power plants. Some of those may be powered by fossil fuels, as in the case of a New Jersey facility recently taken over by the cloud computing company Core Weave, while others may wind up taking zero-carbon power off the grid, as Amazon attempted to do with the Susquehanna nuclear station in Pennsylvania.
Building new natural gas capacity is more difficult in the PJM Interconnection, the country’s largest electricity market, which spans the Eastern Seaboard and a large chunk of the Midwest. Its leadership is hoping high prices can lure new gas generation, but the complexity and uncertainty of the system’s reward structure for companies that agree to supply failsafe capacity has hindered the massive new investment PJM says it needs.
Some clean energy advocates argue that utilities are being short-sighted in their plans to develop new gas resources that could be around for decades — well past corporate, state, or national goals for electric system decarbonization.
“They’re used to building gas plants more so than they’re used to building other things. It reflects a lack of creativity on their part,” Michelle Solomon, a senior policy analyst at Energy Innovation, told me.
But until the system for building and paying for transmission can be reformed to clarify who pays for what and what transmission can be built where — as federal regulators and Congress are trying to do — utilities will likely default to what they know best.
“The difficulty of building transmission certainly can constrain utilities’ ability to serve new load, and it can constrain the ability to serve the load with clean generation,” Gramlich told me.
Chris Seiple, Wood Mackenzie’s vice president of energy transition and power and renewables, echoed Gramlich’s thought in a note from October. “The constraint is not the demand for renewables,” he wrote, “but the ability to get through permitting, interconnection, and building out the transmission system accordingly.”

Any household savings will barely make a dent in the added costs from Trump’s many tariffs.
Donald Trump’s tariffs — the “fentanyl” levies on Canada, China, and Mexico, the “reciprocal” tariffs on nearly every country (and some uninhabited islands), and the global 10% tariff — will almost certainly cause consumer goods on average to get more expensive. The Yale Budget Lab estimates that in combination, the tariffs Trump has announced so far in his second term will cause prices to rise 2.3%, reducing purchasing power by $3,800 per year per household.
But there’s one very important consumer good that seems due to decline in price.
Trump administration officials — including the president himself — have touted cheaper oil to suggest that the economic response to the tariffs hasn’t been all bad. On Sunday, Secretary of the Treasury Scott Bessent told NBC, “Oil prices went down almost 15% in two days, which impacts working Americans much more than the stock market does.”
Trump picked up this line on Truth Social Monday morning. “Oil prices are down, interest rates are down (the slow moving Fed should cut rates!), food prices are down, there is NO INFLATION,” he wrote. He then spent the day posting quotes from Fox Business commentators echoing that idea, first Maria Bartiromo (“Rates are plummeting, oil prices are plummeting, deregulation is happening. President Trump is not going to bend”) then Charles Payne (“What we’re not talking about is, oil was $76, now it’s $65. Gasoline prices are going to plummet”).
But according to Neil Dutta, head of economic research at Renaissance Macro Research, pointing to falling oil prices as a stimulus is just another example of the “4D chess” theory, under which some market participants attribute motives to Trump’s trade policy beyond his stated goal of reducing trade deficits to as near zero (or surplus!) as possible.
Instead, oil markets are primarily “responding to the recession risk that comes from the tariff and the trade war,” Dutta told me. “That is the main story.” In short, oil markets see less global trade and less global production, and therefore falling demand for oil. The effect on household consumption, he said, was a “second order effect.”
It is true that falling oil prices will help “stabilize consumption,” Dutta told me (although they could also devastate America’s own oil industry). “It helps. It’ll provide some lift to real income growth for consumers, because they’re not spending as much on gasoline.” But “to fully offset the trade war effects, you basically need to get oil down to zero.”
That’s confirmed by some simple and extremely back of the envelope math. In 2023, households on average consumed about 700 gallons of gasoline per year, based on Energy Information Administration calculations that the average gasoline price in 2023 was $3.52, while the Bureau of Labor Statistics put average household gasoline expenditures at about $2,450.
Let’s generously assume that due to the tariffs and Trump’s regulatory and diplomatic efforts, gas prices drop from the $3.26 they were at on Monday, according to AAA, to $2.60, the average price in 2019. (GasBuddy petroleum analyst Patrick De Haanwrote Monday that the tariffs combined with OPEC+ production hikes could lead gas prices “to fall below $3 per gallon.”)
Let’s also assume that this drop in gas prices does not cause people to drive more or buy less fuel-efficient vehicles. In that case, those same 700 gallons cost the average American $1,820, which would generate annual savings of $630 on average per household. If we went to the lowest price since the Russian invasion of Ukraine, about $3 per gallon, total consumption of 700 gallons would cost a household about $2,100, saving $350 per household per year.
That being said, $1,820 is a pretty low level for annual gasoline consumption. In 2021, as the economy was recovering from the Covid recession and before gas prices popped, annual gasoline expenditures only got as low as $1,948; in 2020 — when oil prices dropped to literally negative dollars per barrel and gas prices got down to $1.85 a gallon — annual expenditures were just over $1,500.
In any case, if you remember the opening paragraphs of this story, even the most generous estimated savings would go nowhere near surmounting the overall rise in prices forecast by the Yale Budget Lab. $630 is less than $3,800! (JPMorgan has forecast a more mild increase in prices of 1% to 1.5%, but agrees that prices will likely rise and purchasing power will decline.)
But maybe look at it this way: You might be able to drive a little more than you expected to, even as your costs elsewhere are going up. Just please be careful! You don’t want to get into a bad accident and have to replace your car: New car prices are expected to rise by several thousand dollars due to Trump’s tariffs.
With cars about to get more expensive, it might be time to start tinkering.
More than a decade ago, when I was a young editor at Popular Mechanics, we got a Nissan Leaf. It was a big deal. The magazine had always kept long-term test cars to give readers a full report of how they drove over weeks and months. A true test of the first true production electric vehicle from a major car company felt like a watershed moment: The future was finally beginning. They even installed a destination charger in the basement of the Hearst Corporation’s Manhattan skyscraper.
That Leaf was a bit of a lump, aesthetically and mechanically. It looked like a potato, got about 100 miles of range, and delivered only 110 horsepower or so via its electric motors. This made the O.G. Leaf a scapegoat for Top Gear-style car enthusiasts eager to slander EVs as low-testosterone automobiles of the meek, forced upon an unwilling population of drivers. Once the rise of Tesla in the 2010s had smashed that paradigm and led lots of people to see electric vehicles as sexy and powerful, the original Leaf faded from the public imagination, a relic of the earliest days of the new EV revolution.
Yet lots of those cars are still around. I see a few prowling my workplace parking garage or roaming the streets of Los Angeles. With the faded performance of their old batteries, these long-running EVs aren’t good for much but short-distance city driving. Ignore the outdated battery pack for a second, though, and what surrounds that unit is a perfectly serviceable EV.
That’s exactly what a new brand of EV restorers see. Last week, car site The Autopiancovered DIYers who are scooping up cheap old Leafs, some costing as little as $3,000, and swapping in affordable Chinese-made 62 kilowatt-hour battery units in place of the original 24 kilowatt-hour units to instantly boost the car’s range to about 250 miles. One restorer bought a new battery on the Chinese site Alibaba for $6,000 ($4,500, plus $1,500 to ship that beast across the sea).
The possibility of the (relatively) simple battery swap is a longtime EV owner’s daydream. In the earlier days of the electrification race, many manufacturers and drivers saw simple and quick battery exchange as the solution for EV road-tripping. Instead of waiting half an hour for a battery to recharge, you’d swap your depleted unit for a fully charged one and be on your way. Even Tesla tested this approach last decade before settling for good on the Supercharger network of fast-charging stations.
There are still companies experimenting with battery swaps, but this technology lost. Other EV startups and legacy car companies that followed Nissan and Tesla into making production EVs embraced the rechargeable lithium-ion battery that is meant to be refilled at a fast-charging station and is not designed to be easily removed from the vehicle. Buy an electric vehicle and you’re buying a big battery with a long warranty but no clear plan for replacement. The companies imagine their EVs as something like a smartphone: It’s far from impossible to replace the battery and give the car a new life, but most people won’t bother and will simply move on to a new car when they can’t take the limitations of their old one anymore.
I think about this impasse a lot. My 2019 Tesla Model 3 began its life with a nominal 240 miles of range. Now that the vehicle has nearly six years and 70,000 miles on it, its maximum range is down to just 200, while its functional range at highway speed is much less than that. I don’t want to sink money into another vehicle, which means living with an EV’s range that diminishes as the years go by.
But what if, one day, I replaced its battery? Even if it costs thousands of dollars to achieve, a big range boost via a new battery would make an older EV feel new again, and at a cost that’s still far less than financing a whole new car. The thought is even more compelling in the age of Trump-imposed tariffs that will raise already-expensive new vehicles to a place that’s simply out of reach for many people (though new battery units will be heavily tariffed, too).
This is no simple weekend task. Car enthusiasts have been swapping parts and modifying gas-burning vehicles since the dawn of the automotive age, but modern EVs aren’t exactly made with the garage mechanic in mind. Because so few EVs are on the road, there is a dearth of qualified mechanics and not a huge population of people with the savvy to conduct major surgery on an electric car without electrocuting themselves. A battery-replacing owner would need to acquire not only the correct pack but also potentially adapters and other equipment necessary to make the new battery play nice with the older car. Some Nissan Leaf modifiers are finding their replacement packs aren’t exactly the same size, shape or weight, The Autopian says, meaning they need things like spacers to make the battery sit in just the right place.
A new battery isn’t a fix-all either. The motors and other electrical components wear down and will need to be replaced eventually, too. A man in Norway who drove his Tesla more than a million miles has replaced at least four battery packs and 14 motors, turning his EV into a sort of car of Theseus.
Crucially, though, EVs are much simpler, mechanically, than combustion-powered cars, what with the latter’s belts and spark plugs and thousands of moving parts. The car that surrounds a depleted battery pack might be in perfectly good shape to keep on running for thousands of miles to come if the owner were to install a new unit, one that could potentially give the EV more driving range than it had when it was new.
The battery swap is still the domain of serious top-tier DIYers, and not for the mildly interested or faint of heart. But it is a sign of things to come. A market for very affordable used Teslas is booming as owners ditch their cars at any cost to distance themselves from Elon Musk. Old Leafs, Chevy Bolts and other EVs from the 2010s can be had for cheap. The generation of early vehicles that came with an unacceptably low 100 to 150 miles of range would look a lot more enticing if you imagine today’s battery packs swapped into them. The possibility of a like-new old EV will look more and more promising, especially as millions of Americans realize they can no longer afford a new car.
On the shifting energy mix, tariff impacts, and carbon capture
Current conditions: Europe just experienced its warmest March since record-keeping began 47 years ago • It’s 105 degrees Fahrenheit in India’s capital Delhi where heat warnings are in effect • The risk of severe flooding remains high across much of the Mississippi and Ohio Valleys.
The severe weather outbreak that has brought tornadoes, extreme rainfall, hail, and flash flooding to states across the central U.S. over the past week has already caused between $80 billion and $90 billion in damages and economic losses, according to a preliminary estimate from AccuWeather. The true toll is likely to be costlier because some areas have yet to report their damages, and the flooding is ongoing. “A rare atmospheric river continually resupplying a firehose of deep tropical moisture into the central U.S., combined with a series of storms traversing the same area in rapid succession, created a ‘perfect storm’ for catastrophic flooding and devastating tornadoes,” said AccuWeather’s chief meteorologist Jonathan Porter. The estimate takes into account damages to buildings and infrastructure, as well as secondary effects like supply chain and shipping disruptions, extended power outages, and travel delays. So far 23 people are known to have died in the storms. “This is the third preliminary estimate for total damage and economic loss that AccuWeather experts have issued so far this year,” the outlet noted in a release, “outpacing the frequency of major, costly weather disasters since AccuWeather began issuing estimates in 2017.”

Low-emission energy sources accounted for 41% of global electricity generation in 2024, up from 39.4% in 2023, according to energy think tank Ember’s annual Global Electricity Review. That includes renewables as well as nuclear. If nuclear is left out of the equation, renewables alone made up 32% of power generation last year. Overall, renewables added a record 858 terawatt hours, nearly 50% more than the previous record set in 2022. Hydro was the largest source of low-carbon power, followed by nuclear. But wind and solar combined overtook hydro last year, while nuclear’s share of the energy mix reached a 45-year low. More solar capacity was installed in 2024 than in any other single year.

The report notes that demand for electricity rose thanks to heat waves and air conditioning use. This resulted in a slight, 1.4% annual increase in fossil-fuel power generation and pushed power-sector emissions to a new all-time high of 14.5 billion metric tons. “Clean electricity generation met 96% of the demand growth not caused by hotter temperatures,” the report said.
President Trump’s new tariffs will have a “limited” effect on the amount of solar components the U.S. imports from Asia because the U.S. already imposes tariffs on these products, according to a report from research firm BMI. That said, the U.S. still relies heavily on imported solar cells, and the new fees are likely to raise costs for domestic manufacturers and developers, which will ultimately be passed on to buyers and could slow solar growth. “Since the U.S.’s manufacturing capacity is insufficient to meet demand for solar, wind, and grid components, we do expect that costs will increase for developers due to the tariffs which will now be imposed upon these components,” BMI wrote.
In other tariff news, the British government is adjusting its 2030 target of ending the sale of new internal combustion engine cars to ease some of the pain from President Trump’s new 25% auto tariffs. Under the U.K.’s new EV mandate, carmakers will be able to sell new hybrids through 2035 (whereas the previous version of the rules banned them by 2030), and gas and diesel vans can also be sold through 2035. The changes also carve out exemptions for luxury supercar brands like McLaren and Aston Martin, which will be allowed to keep selling new ICE vehicles beyond 2030 because, the government says, they produce so few. The goal is to “help ease the transition and give industry more time to prepare.” British Transport Secretary Heidi Alexander insisted the changes have been “carefully calibrated” and their impact on carbon emissions is “negligible.” As The New York Timesnoted, the U.S. is the largest single-country export market for British cars.
The Environmental Protection Agency has approved Occidental Petroleum’s application to capture and sequester carbon dioxide at its direct air capture facility in Texas, and issued permits that will allow the company to drill and inject the gas more than one mile underground. The Stratos DAC plant is being developed by Occidental subsidiary 1PointFive. As Heatmap’s Katie Brigham has reported, Stratos is designed to remove up to 500,000 metric tons of CO2 annually and set to come online later this year. Its success (or failure) could shape the future of DAC investment at a time when the Trump administration is hollowing out the Department of Energy’s nascent Carbon Dioxide Removal team and casting doubt over the future of the DOE’s $3.5 billion Regional Direct Air Capture Hubs program. While Stratos is not a part of the hubs program, it will use the same technology as Occidental’s South Texas DAC hub.
The Bezos Earth Fund and the Global Methane Hub are launching a $27 million effort to fund research into selectively breeding cattle that emit less methane.
