If you’re going to have a giant hole of water in your backyard, put it to good use.

In the grand ranking of Fun Things You Should Feel Bad About, swimming pools are up there with Oreos and road trips. After all, when the U.N. says two-thirds of the world could face water-stressed conditions by 2025, it tends to put a damper on the guilt-free enjoyment of the giant hole of clean water in your backyard.
A new study published Monday in the journal Nature Sustainability more or less confirmed that yes, swimming pool ownership is bad. Looking at water usage in Cape Town, South Africa, the researchers found that the richest residents, who make up 14% of the population, consume 51% of the city’s water by doing things like “garden watering, car washing, and filling swimming pools,” while the city’s poorest residents, who make up 62% of the population, consume just 27% of the water resources doing things like “maintaining basic hygiene” and “hydrating themselves.” As the researchers concluded, “Urban water crises can be triggered by the unsustainable consumption patterns of privileged social groups.”
One takeaway from this study, though, is that the problem isn’t so much the swimming pools — which have many positive benefits — but the fact that the pools are in the hands of “privileged social groups,” where they go heavily underutilized. Private pools are often only used by one family, the homeowner’s, and only for a few months a year, if that. To make the tremendous energy and water costs of swimming pools actually worth it, we need to get a lot more people into them.
America used to be covered in these sorts of community pools, some of which could fit a thousand swimmers or more. During the 1880s and early 1890s, municipal swimming pools were places “where Blacks, immigrants, and native-born white laborers swam together,” though people of mixed classes and sexes did not, author Jeff Wiltse writes in Contested Waters: A Social History of Swimming Pools in America. As Wiltse explains, “During the Gilded Age and Progressive Era, the difference between people with ‘black’ skin and those with ‘white’ skin was a less significant social distinction than class … That changed during the 1920s, when race emerged as the most salient and divisive social distinction.”
Municipal pools were frequently segregated after World War I, but they were also “extraordinarily popular" from the 1920s to the 1940s, with swimming as much a part of the average American’s life as going to the movies. Tens of millions of Americans visited community pools each year, with sometimes “hundreds and even thousands of people at a time” taking a dip. But after desegregation in the 1950s opened public pools to everyone, some bigoted communities “found a loophole,” The New York Times writes. They could also close the pools for everyone.
So-called “drained-pool politics,” the attitude that “if ‘they’ can also have it, then no one can … helps explain why America still doesn’t have a truly universal health care system, a child care system, [or] a decent social safety net,” the Times postulates. For our immediate purposes, it also explains the rise of private pools across the country: “After racial desegregation, millions of Americans chose to stop swimming at municipal pools and chose instead to organize and join private swim clubs,” Wiltse writes. Those discriminatory choices still reverberate today: There were fewer than 15,000 pools at private homes before 1952; now there are more than 10.4 million. By comparison, there are only about 300,000 municipal pools in the U.S. and many are closing because they’re too expensive to maintain.
But as the world continues to warm, community pools are becoming vital pieces of infrastructure again. We know that small bodies of manmade water can actually somewhat help to cool down urban areas; we also know that having access to water like beaches and pools saves lives when cooling centers are in short supply. They also offer an outlet for physical recreation when others become dangerous or deeply unpleasant due to high temperatures. Additionally, part of the original popularity of community pools had been as relief from the heat before air conditioning; from an energy-saving standpoint, it still makes sense today to turn off your a/c whenever possible and cool down in water instead.
Despite all the net good of public pools, there hasn’t been a lot of movement to actually build more: only 198 of 3,310 commercial pools built in the U.S. in 2020 went into parks, Bloomberg reports (most of the rest “went to hotels and multi-family developments”). And while we shouldn’t take our foot off the gas in advocating for more swimming facilities, particularly in lower-income areas, private pool owners can also do themselves, the planet, and the rest of us a solid — and share. Pool party, anyone?
Okay, so no, pool parties obviously won’t fix over a century of racially motivated infrastructure decisions. Nor are they very likely to fix the “atomized recreation and diminished public discourse” that Wiltse says resulted from “private-pool owners [fencing] themselves into their own backyards,” since said private-pool owners would presumably be inviting attendees from their own homogenous social groups.
But sometimes pool ownership happens to good people, and it is in those cases that wringing as much use out of a pool as possible — and in doing so, minimizing the per-person costs of maintenance, energy expenditure, and water usage — actually start to make sense. Grist found that “the average pool uses about 20,000 gallons of water a year,” which is “a little less than a lawn” — lawns, of course, being another item up there on the Fun Things You Should Feel Bad About list. But if 50 people share one lawn, it starts to look a little less wasteful, particularly if that “lawn” also serves as a cornerstone of the community and local social life. (Introverted pool owners, meanwhile, can list theirs cheaply on Swimply, the “Airbnb for swimming pools,” so others can enjoy them when they’d otherwise be sitting empty).
Pool parties won’t save the world; to be honest, they won’t even entirely redeem private pools. But they could start to make swimming more broadly social again and nudge us back toward a culture where taking a dip with acquaintances, neighbors, and strangers is a value rather than a source of disgust and suspicion. It may be a drop in the bucket, but it’s one that’s worth it.

According to a new analysis shared exclusively with Heatmap, coal’s equipment-related outage rate is about twice as high as wind’s.
The Trump administration wants “beautiful clean coal” to return to its place of pride on the electric grid because, it says, wind and solar are just too unreliable. “If we want to keep the lights on and prevent blackouts from happening, then we need to keep our coal plants running. Affordable, reliable and secure energy sources are common sense,” Chris Wright said on X in July, in what has become a steady drumbeat from the administration that has sought to subsidize coal and put a regulatory straitjacket around solar and (especially) wind.
This has meant real money spent in support of existing coal plants. The administration’s emergency order to keep Michigan’s J.H. Campbell coal plant open (“to secure grid reliability”), for example, has cost ratepayers served by Michigan utility Consumers Energy some $80 million all on its own.
But … how reliable is coal, actually? According to an analysis by the Environmental Defense Fund of data from the North American Electric Reliability Corporation, a nonprofit that oversees reliability standards for the grid, coal has the highest “equipment-related outage rate” — essentially, the percentage of time a generator isn’t working because of some kind of mechanical or other issue related to its physical structure — among coal, hydropower, natural gas, nuclear, and wind. Coal’s outage rate was over 12%. Wind’s was about 6.6%.
“When EDF’s team isolated just equipment-related outages, wind energy proved far more reliable than coal, which had the highest outage rate of any source NERC tracks,” EDF told me in an emailed statement.
Coal’s reliability has, in fact, been decreasing, Oliver Chapman, a research analyst at EDF, told me.
NERC has attributed this falling reliability to the changing role of coal in the energy system. Reliability “negatively correlates most strongly to capacity factor,” or how often the plant is running compared to its peak capacity. The data also “aligns with industry statements indicating that reduced investment in maintenance and abnormal cycling that are being adopted primarily in response to rapid changes in the resource mix are negatively impacting baseload coal unit performance.” In other words, coal is struggling to keep up with its changing role in the energy system. That’s due not just to the growth of solar and wind energy, which are inherently (but predictably) variable, but also to natural gas’s increasing prominence on the grid.
“When coal plants are having to be a bit more varied in their generation, we're seeing that wear and tear of those plants is increasing,” Chapman said. “The assumption is that that's only going to go up in future years.”
The issue for any plan to revitalize the coal industry, Chapman told me, is that the forces driving coal into this secondary role — namely the economics of running aging plants compared to natural gas and renewables — do not seem likely to reverse themselves any time soon.
Coal has been “sort of continuously pushed a bit more to the sidelines by renewables and natural gas being cheaper sources for utilities to generate their power. This increased marginalization is going to continue to lead to greater wear and tear on these plants,” Chapman said.
But with electricity demand increasing across the country, coal is being forced into a role that it might not be able to easily — or affordably — play, all while leading to more emissions of sulfur dioxide, nitrogen oxide, particulate matter, mercury, and, of course, carbon dioxide.
The coal system has been beset by a number of high-profile outages recently, including at the largest new coal plant in the country, Sandy Creek in Texas, which could be offline until early 2027, according to the Texas energy market ERCOT and the Institute for Energy Economics and Financial Analysis.
In at least one case, coal’s reliability issues were cited as a reason to keep another coal generating unit open past its planned retirement date.
Last month, Colorado Representative Will Hurd wrote a letter to the Department of Energy asking for emergency action to keep Unit 2 of the Comanche coal plant in Pueblo, Colorado open past its scheduled retirement at the end of his year. Hurd cited “mechanical and regulatory constraints” for the larger Unit 3 as a justification for keeping Unit 2 open, to fill in the generation gap left by the larger unit. In a filing by Xcel and several Colorado state energy officials also requesting delaying the retirement of Unit 2, they disclosed that the larger Unit 3 “experienced an unplanned outage and is offline through at least June 2026.”
Reliability issues aside, high electricity demand may turn into short-term profits at all levels of the coal industry, from the miners to the power plants.
At the same time the Trump administration is pushing coal plants to stay open past their scheduled retirement, the Energy Information Administration is forecasting that natural gas prices will continue to rise, which could lead to increased use of coal for electricity generation. The EIA forecasts that the 2025 average price of natural gas for power plants will rise 37% from 2024 levels.
Analysts at S&P Global Commodity Insights project “a continued rebound in thermal coal consumption throughout 2026 as thermal coal prices remain competitive with short-term natural gas prices encouraging gas-to-coal switching,” S&P coal analyst Wendy Schallom told me in an email.
“Stronger power demand, rising natural gas prices, delayed coal retirements, stockpiles trending lower, and strong thermal coal exports are vital to U.S. coal revival in 2025 and 2026.”
And we’re all going to be paying the price.
Rural Marylanders have asked for the president’s help to oppose the data center-related development — but so far they haven’t gotten it.
A transmission line in Maryland is pitting rural conservatives against Big Tech in a way that highlights the growing political sensitivities of the data center backlash. Opponents of the project want President Trump to intervene, but they’re worried he’ll ignore them — or even side with the data center developers.
The Piedmont Reliability Project would connect the Peach Bottom nuclear plant in southern Pennsylvania to electricity customers in northern Virginia, i.e.data centers, most likely. To get from A to B, the power line would have to criss-cross agricultural lands between Baltimore, Maryland and the Washington D.C. area.
As we chronicle time and time again in The Fight, residents in farming communities are fighting back aggressively – protesting, petitioning, suing and yelling loudly. Things have gotten so tense that some are refusing to let representatives for Piedmont’s developer, PSEG, onto their properties, and a court battle is currently underway over giving the company federal marshal protection amid threats from landowners.
Exacerbating the situation is a quirk we don’t often deal with in The Fight. Unlike energy generation projects, which are usually subject to local review, transmission sits entirely under the purview of Maryland’s Public Service Commission, a five-member board consisting entirely of Democrats appointed by current Governor Wes Moore – a rumored candidate for the 2028 Democratic presidential nomination. It’s going to be months before the PSC formally considers the Piedmont project, and it likely won’t issue a decision until 2027 – a date convenient for Moore, as it’s right after he’s up for re-election. Moore last month expressed “concerns” about the project’s development process, but has brushed aside calls to take a personal position on whether it should ultimately be built.
Enter a potential Trump card that could force Moore’s hand. In early October, commissioners and state legislators representing Carroll County – one of the farm-heavy counties in Piedmont’s path – sent Trump a letter requesting that he intervene in the case before the commission. The letter followed previous examples of Trump coming in to kill planned projects, including the Grain Belt Express transmission line and a Tennessee Valley Authority gas plant in Tennessee that was relocated after lobbying from a country rock musician.
One of the letter’s lead signatories was Kenneth Kiler, president of the Carroll County Board of Commissioners, who told me this lobbying effort will soon expand beyond Trump to the Agriculture and Energy Departments. He’s hoping regulators weigh in before PJM, the regional grid operator overseeing Mid-Atlantic states. “We’re hoping they go to PJM and say, ‘You’re supposed to be managing the grid, and if you were properly managing the grid you wouldn’t need to build a transmission line through a state you’re not giving power to.’”
Part of the reason why these efforts are expanding, though, is that it’s been more than a month since they sent their letter, and they’ve heard nothing but radio silence from the White House.
“My worry is that I think President Trump likes and sees the need for data centers. They take a lot of water and a lot of electric [power],” Kiler, a Republican, told me in an interview. “He’s conservative, he values property rights, but I’m not sure that he’s not wanting data centers so badly that he feels this request is justified.”
Kiler told me the plan to kill the transmission line centers hinges on delaying development long enough that interest rates, inflation and rising demand for electricity make it too painful and inconvenient to build it through his resentful community. It’s easy to believe the federal government flexing its muscle here would help with that, either by drawing out the decision-making or employing some other as yet unforeseen stall tactic. “That’s why we’re doing this second letter to the Secretary of Agriculture and Secretary of Energy asking them for help. I think they may be more sympathetic than the president,” Kiler said.
At the moment, Kiler thinks the odds of Piedmont’s construction come down to a coin flip – 50-50. “They’re running straight through us for data centers. We want this project stopped, and we’ll fight as well as we can, but it just seems like ultimately they’re going to do it,” he confessed to me.
Thus is the predicament of the rural Marylander. On the one hand, Kiler’s situation represents a great opportunity for a GOP president to come in and stand with his base against a would-be presidential candidate. On the other, data center development and artificial intelligence represent one of the president’s few economic bright spots, and he has dedicated copious policy attention to expanding growth in this precise avenue of the tech sector. It’s hard to imagine something less “energy dominance” than killing a transmission line.
The White House did not respond to a request for comment.
Plus more of the week’s most important fights around renewable energy.
1. Wayne County, Nebraska – The Trump administration fined Orsted during the government shutdown for allegedly killing bald eagles at two of its wind projects, the first indications of financial penalties for energy companies under Trump’s wind industry crackdown.
2. Ocean County, New Jersey – Speaking of wind, I broke news earlier this week that one of the nation’s largest renewable energy projects is now deceased: the Leading Light offshore wind project.
3. Dane County, Wisconsin – The fight over a ginormous data center development out here is turning into perhaps one of the nation’s most important local conflicts over AI and land use.
4. Hardeman County, Texas – It’s not all bad news today for renewable energy – because it never really is.
