Fossil fuel plant retirements are slowing down, and projected load growth is to blame.
To fully decarbonize the electricity system will require more than just the rapid deployment of non-carbon-emitting generation capacity, plus the transmission necessary to get that electricity to where it needs to go. It will also require that our existing stock of electricity generation — which is largely natural gas- and coal-powered — get mostly mothballed. So far, this process has been proceeding briskly. Renewable deployment is on the way up and is projected to accelerate, and older electricity generation was sliding quickly but gracefully into retirement — until recently.
Retirements of existing generation have slowed down dramatically in the first half of this year, which is on pace to be the slowest for existing generation retirements since 2011, according to new data from the Energy Information Administration.
In the first half of the year, some 5.1 gigawatts of generating capacity have been retired, and another 2.4 gigawatts are scheduled to be retired by year’s end, for a projected total of 7.5 retired gigawatts. From 2004 to 2023, by contrast, just over 12 gigawatts of capacity were retired each year on average, with almost 15 gigawatts retired per year this decade. Since 2022, according to EIA data, over 90% of retired capacity has been coal or natural gas.
What’s behind the slowdown? “Reliability is threatened because the grid conditions are tightening,” Douglas Giuffre, executive director of gas, power and renewables analysis at S&P Global Commodity Insights, explained in an email. “This is partly due to the recent pace of coal and natural gas retirements in the U.S., which worked off some of the excess capacity in power markets. Now we are seeing tighter reserve margins, and a relatively thin pipeline of new gas-fired projects that can come online quickly.” That’s especially concerning for utilities at a time when projected electricity demand is way, way up.
The wave of retirements was a national phenomenon, often having nothing to do with state-level plans to decarbonize. Coal and gas were being retired so steadily over the past 20 years not just because plants were aging, but also because power use was essentially flat from the early 2000s through, essentially, yesterday. This meant that older plants — especially dirty coal plants — became uneconomic to run, especially as natural gas prices began to fall.
Now, we are in a completely different world. Electricity use is forecast to start growing again, thanks to a buildout of new data centers and manufacturing, plus the ongoing electrification of automobiles and home heating and cooling.
The Southeast offers an example of how these trends have played out on the ground. In December 2020, the Mississippi Public Service Commission determined that the state had “excess reserves … largely due to decreases in projected load” and ordered a 950 megawatt reduction in generating capacity by Mississippi Power by 2027. A consulting firm hired by the commission determined that Plant Daniel, a coal plant, was “relatively inefficient compared to other available resources;” a few months later, the utility said it would decommission Plant Daniel by 2027.
Then Georgia Power, the utility that covers most of the state (and, like Mississippi Power, a subsidiary of Southern Company), rushed out a new three-year plan for its future power usage less than a year after finalizing its old one. Its demand forecast through the end of the decade had jumped from 400 megawatts to 6,600 megawatts, the result of a projected boom in data center construction.
“They came in with a preselected list of ways it wanted to meet that power need,” including buying power from Plant Daniel and new gas, Bob Sherrier, a staff attorney at the Southern Environmental Law Center, told me. Georgia Power told the state’s utility commission that to respond to growing demand it would need to extend contracts with its sister utility in Mississippi — which meant not only that Daniel would remain open for at least another year — and build new new plants that could run on gas or diesel, plans for which regulators approved on Tuesday. The utility also hinted that its existing plans to euthanize, for the most part, its coal-fired generation fleet by the end of 2028 were likely to be revised.
“To meet that projected need, the utilities are reverting to what they know, which is fossil fuels,” Sherrier said.
In vertically integrated markets, where utilities own generating assets and sell power to customers, environmentalists have seen delayed retirements and the building of new fossil plants as examples of utilities slipping into their comfort zone, building and operating expensive projects instead of developing or procuring renewables to handle rising demand.
But it's not just in vertically integrated markets where fossil retirements are being delayed. In Maryland, for instance, Brandon Shores, a coal-fired power plant that was scheduled to close in 2025, is staying open because PJM Interconnection, the regional electricity market, determined that a plan to replace it with battery storage was not a “realistic option at present” nor “technically viable to resolve the reliability violations or avoid the need for an RMR agreement at this time,” PJM president Manu Asthana said in a letter to Paul Pinsky, the director of the Maryland Energy Administration. The transmission investments required to make up the difference, meanwhile, would take several years.
Along with the neighboring Wagner plant, which burns a mix of coal, oil, and natural gas, Brandon Shores will likely stay open more than three years past its planned retirement date thanks to what’s known as a “reliability must run” contract, which “would put Maryland ratepayers on the hook for over $600 million dollars in out-of-market payments,” according to a letter written by several Maryland congressional representatives to PJM.
Environmental advocates have blamed PJM for not doing enough proactive transmission planning to account for predictable and scheduled plant retirements.
The slowing retirements mean that emissions from the electricity sector, which have been falling since the mid-2000s (with occasional bumps up as the economy has recovered from downturns), are expected to plateau over the next year or so. EIA forecasts show carbon dioxide emissions from electricity as essentially flat from 2023 to 2025, with increased natural gas emissions essentially offsetting falling coal emissions.
There is a bright side to the data, however. So far this year, the U.S. has installed just over 20 gigawatts of new generation, 80% of which has been solar and battery storage, including a 600-plus megawatt projects in Nevada and Texas. If added generation comes on in the second half of this year as planned, the EIA projects we’ll have 15 gigawatts of battery storage by year’s end. Along with the large and growing solar generation in states like California, Nevada, and Texas, the U.S. is getting closer to a grid that can, at least, run without carbon emissions day or night.

Though it might not be as comprehensive or as permanent as renewables advocates have feared, it’s also “just the beginning,” the congressman said.
President-elect Donald Trump’s team is drafting an executive order to “halt offshore wind turbine activities” along the East Coast, working with the office of Republican Rep. Jeff Van Drew of New Jersey, the congressman said in a press release from his office Monday afternoon.
“This executive order is just the beginning,” Van Drew said in a statement. “We will fight tooth and nail to prevent this offshore wind catastrophe from wreaking havoc on the hardworking people who call our coastal towns home.”
The announcement indicates that some in the anti-wind space are leaving open the possibility that Trump’s much-hyped offshore wind ban may be less sweeping than initially suggested.
In its press release, Van Drew’s office said the executive order would “lay the groundwork for permanent measures against the projects,” leaving the door open to only a temporary pause on permitting new projects. The congressman had recently told New Jersey reporters that he anticipates only a six-month moratorium on offshore wind.
The release also stated that the “proposed order” is “expected to be finalized within the first few months of the administration,” which is a far cry from Trump’s promise to stop projects on Day 1. If enacted, a pause would essentially halt all U.S. offshore wind development because the sought-after stretches of national coastline are entirely within federal waters.
Whether this is just caution from Van Drew’s people or a true moderation of Trump’s ambition we’ll soon find out. Inauguration Day is in less than a week.
Imagine for a moment that you’re an aerial firefighter pilot. You have one of the most dangerous jobs in the country, and now you’ve been called in to fight the devastating fires burning in Los Angeles County’s famously tricky, hilly terrain. You’re working long hours — not as long as your colleagues on the ground due to flight time limitations, but the maximum scheduling allows — not to mention the added external pressures you’re also facing. Even the incoming president recently wondered aloud why the fires aren’t under control yet and insinuated that it’s your and your colleagues’ fault.
You’re on a sortie, getting ready for a particularly white-knuckle drop at a low altitude in poor visibility conditions when an object catches your eye outside the cockpit window: an authorized drone dangerously close to your wing.
Aerial firefighters don’t have to imagine this terrifying scenario; they’ve lived it. Last week, a drone punched a hole in the wing of a Québécois “Super Scooper” plane that had traveled down from Canada to fight the fires, grounding Palisades firefighting operations for an agonizing half-hour. Thirty minutes might not seem like much, but it is precious time lost when the Santa Ana winds have already curtailed aerial operations.
“I am shocked by what happened in Los Angeles with the drone,” Anna Lau, a forestry communication coordinator with the Montana Department of Natural Resources and Conservation, told me. The Montana DNRC has also had to contend with unauthorized drones grounding its firefighting planes. “We’re following what’s going on very closely, and it’s shocking to us,” Lau went on. Leaving the skies clear so that firefighters can get on with their work “just seems like a no-brainer, especially when people are actively trying to tackle the situation at hand and fighting to save homes, property, and lives.”

Although the Super Scooper collision was by far the most egregious case, according to authorities there have been at least 40 “incidents involving drones” in the airspace around L.A. since the fires started. (Notably, the Federal Aviation Administration has not granted any waivers for the air space around Palisades, meaning any drone images you see of the region, including on the news, were “probably shot illegally,” Intelligencer reports.) So far, law enforcement has arrested three people connected to drones flying near the L.A. fires, and the FBI is seeking information regarding the Super Scooper collision.
Such a problem is hardly isolated to these fires, though. The Forest Service reports that drones led to the suspension of or interfered with at least 172 fire responses between 2015 and 2020. Some people, including Mike Fraietta, an FAA-certified drone pilot and the founder of the drone-detection company Gargoyle Systems, believe the true number of interferences is much higher — closer to 400.
Law enforcement likes to say that unauthorized drone use falls into three buckets — clueless, criminal, or careless — and Fraietta was inclined to believe that it’s mostly the former in L.A. Hobbyists and other casual drone operators “don’t know the regulations or that this is a danger,” he said. “There’s a lot of ignorance.” To raise awareness, he suggested law enforcement and the media highlight the steep penalties for flying drones in wildfire no-fly zones, which is punishable by up to 12 months in prison or a fine of $75,000.
“What we’re seeing, particularly in California, is TikTok and Instagram influencers trying to get a shot and get likes,” Fraietta conjectured. In the case of the drone that hit the Super Scooper, it “might have been a case of citizen journalism, like, Well, I have the ability to get this shot and share what’s going on.”
Emergency management teams are waking up, too. Many technologies are on the horizon for drone detection, identification, and deflection, including Wi-Fi jamming, which was used to ground climate activists’ drones at Heathrow Airport in 2019. Jamming is less practical in an emergency situation like the one in L.A., though, where lives could be at stake if people can’t communicate.
Still, the fact of the matter is that firefighters waste precious time dealing with drones when there are far more pressing issues that need their attention. Lau, in Montana, described how even just a 12-minute interruption to firefighting efforts can put a community at risk. “The biggest public awareness message we put out is, ‘If you fly, we can’t,’” she said.
Fraietta, though, noted that drone technology could be used positively in the future, including on wildfire detection and monitoring, prescribed burns, and communicating with firefighters or victims on the ground.
“We don’t want to see this turn into the FAA saying, ‘Hey everyone, no more drones in the United States because of this incident,’” Fraietta said. “You don’t shut down I-95 because a few people are running drugs up and down it, right? Drones are going to be super beneficial to the country long term.”
But critically, in the case of a wildfire, such tools belong in the right hands — not the hands of your neighbor who got a DJI Mini 3 for Christmas. “Their one shot isn’t worth it,” Lau said.

Plus 3 more outstanding questions about this ongoing emergency.
As Los Angeles continued to battle multiple big blazes ripping through some of the most beloved (and expensive) areas of the city on Friday, a question lingered in the background: What caused the fires in the first place?
Though fires are less common in California during this time of the year, they aren’t unheard of. In early December 2017, power lines sparked the Thomas Fire near Ventura, California, which burned through to mid-January. At the time it was the largest fire in the state since at least the 1930s. Now it’s the ninth-largest. Although that fire was in a more rural area, it ignited for some of the same reasons we’re seeing fires this week.
Read on for everything we know so far about how the fires started.
Six major fires started during the Santa Ana wind event last week:
Officials are investigating the cause of the fires and have not made any public statements yet. Early eyewitness accounts suggest that the Eaton Fire may have started at the base of a transmission tower owned by Southern California Edison. So far, the company has maintained that an analysis of its equipment showed “no interruptions or electrical or operational anomalies until more than one hour after the reported start time of the fire.” A Washington Post investigation found that the Palisades Fire could have risen from the remnants of a fire that burned on New Year’s Eve and reignited.
On Thursday morning, Edward Nordskog, a retired fire investigator from the Los Angeles Sheriff’s Department, told me it was unlikely they had even begun looking into the root of the biggest and most destructive of the fires in the Pacific Palisades. “They don't start an investigation until it's safe to go into the area where the fire started, and it just hasn't been safe until probably today,” he said.
It can take years to determine the cause of a fire. Investigators did not pinpoint the cause of the Thomas Fire until March 2019, more than two years after it started.
But Nordskog doesn’t think it will take very long this time. It’s easier to narrow down the possibilities for an urban fire because there are typically both witnesses and surveillance footage, he told me. He said the most common causes of wildfires in Los Angeles are power lines and those started by unhoused people. They can also be caused by sparks from vehicles or equipment.
At more than 40,000 acres burned total, these fires are unlikely to make the charts for the largest in California history. But because they are burning in urban, densely populated, and expensive areas, they could be some of the most devastating. With an estimated 9,000 structures damaged as of Friday morning, the Eaton and Palisades fires are likely to make the list for most destructive wildfire events in the state.
And they will certainly be at the top for costliest. The Palisades Fire has already been declared a likely contender for the most expensive wildfire in U.S. history. It has destroyed more than 5,000 structures in some of the most expensive zip codes in the country. Between that and the Eaton Fire, Accuweather estimates the damages could reach $57 billion.
While we don’t know the root causes of the ignitions, several factors came together to create perfect fire conditions in Southern California this week.
First, there’s the Santa Ana winds, an annual phenomenon in Southern California, when very dry, high-pressure air gets trapped in the Great Basin and begins escaping westward through mountain passes to lower-pressure areas along the coast. Most of the time, the wind in Los Angeles blows eastward from the ocean, but during a Santa Ana event, it changes direction, picking up speed as it rushes toward the sea.
Jon Keeley, a research scientist with the US Geological Survey and an adjunct professor at the University of California, Los Angeles told me that Santa Ana winds typically blow at maybe 30 to 40 miles per hour, while the winds this week hit upwards of 60 to 70 miles per hour. “More severe than is normal, but not unique,” he said. “We had similar severe winds in 2017 with the Thomas Fire.”
Second, Southern California is currently in the midst of extreme drought. Winter is typically a rainier season, but Los Angeles has seen less than half an inch of rain since July. That means that all the shrubland vegetation in the area is bone-dry. Again, Keeley said, this was not usual, but not unique. Some years are drier than others.
These fires were also not a question of fuel management, Keeley told me. “The fuels are not really the issue in these big fires. It's the extreme winds,” he said. “You can do prescription burning in chaparral and have essentially no impact on Santa Ana wind-driven fires.” As far as he can tell, based on information from CalFire, the Eaton Fire started on an urban street.
While it’s likely that climate change played a role in amplifying the drought, it’s hard to say how big a factor it was. Patrick Brown, a climate scientist at the Breakthrough Institute and adjunct professor at Johns Hopkins University, published a long post on X outlining the factors contributing to the fires, including a chart of historic rainfall during the winter in Los Angeles that shows oscillations between wet and dry years over the past eight decades.
But climate change is expected to make dry years drier and wet years wetter, creating a “hydroclimate whiplash,” as Daniel Swain, a pre-eminent expert on climate change and weather in California puts it. In a thread on Bluesky, Swain wrote that “in 2024, Southern California experienced an exceptional episode of wet-to-dry hydroclimate whiplash.” Last year’s rainy winter fostered abundant plant growth, and the proceeding dryness primed the vegetation for fire.
