The world’s biggest, most functional city might also be the most pedestrian-friendly. That’s not a coincidence.

For cities that want to reduce the number of cars, bike lanes are a good place to start. They are cheap, usually city-level authorities can introduce them, and they do not require you to raise taxes on people who own cars. What if you want to do something more radical though? What would a city that genuinely wanted to get the car out of its citizens’ lives in a much bigger way do? A city that wanted to make it possible for most people to live decent lives and be able to get around without needing a car, even without needing to get on a bicycle?
There is only one city on Earth I have ever visited that has truly managed this. But it happens to be the biggest city on the planet: Tokyo, the capital of Japan.
In popular imagination, at least in the West, Tokyo is both incredibly futuristic, and also rather foreign and confusing. Before I first visited, in 2017, I imagined it to be an incredibly hectic place, a noisy, bustling megacity. I was on holiday and trying to escape Nairobi, the rather sprawling, low-height, and green city I was living in at the time, and I picked Tokyo largely because I wanted to get as far away from Africa as I could. I needed a break from the traffic jams, the power cuts, the constant negotiation to achieve anything, and the heat. I was looking for an escape somewhere as different as I could think of, and I wanted to ride trains around and look at high-tech skyscrapers and not worry about getting splattered by mud walking in the street. I was expecting to feel bowled over by the height of the buildings, the sheer crush of people, and the noise.
Yet when I emerged from the train station in Shibuya, blinking jetlagged in the morning light after a night flight from Amsterdam, what actually caught me off guard was not the bustle but rather how quiet the city is. When you see cliched images of Tokyo, what invariably is shown are the enormous crowds of pedestrians crossing the roads, or Mount Fuji in the background of the futuristic skyline. I expected something like Los Angeles in Blade Runner, I suppose — futuristic and overwhelming. From photos, Tokyo can look almost unplanned, with neon signs everywhere and a huge variety of forms of architecture. You expect it to feel messy. What I experienced, however, was a city that felt almost like being in a futuristic village. It is utterly calm, in a way that is actually rather strange.
And it took me a little while to realize why. There is simply no traffic noise. No hooting, no engine noise, not even much of the noise of cars accelerating on tarmac. Because there are so few of them. Most of the time you can walk in the middle of the street, so rare is the traffic. There are not even cars parked at the side of the road. That is not true of all of Tokyo, of course. The expressways are often packed. Occasionally, I was told, particularly when it snows, or during holidays when large numbers of people try to drive out to the countryside, jams form that can trap drivers for whole days. But on most residential streets, traffic is almost nonexistent. Even the relatively few cars that you do see are invariably tiny, quiet vehicles.
Among rich cities, Tokyo has the lowest car use in the world. According to Deloitte, a management consultancy, just 12 percent of journeys are completed by private car. It might surprise you to hear that cycling is actually more popular than driving in Tokyo — it accounts for 17 percent of journeys, though the Japanese do not make as much of a big deal out of it as the Dutch do. But walking and public transport dwarf both sorts of vehicles. Tokyo has the most-used public transport system in the world, with 30 million people commuting by train each day. This may sound rather unpleasant. You have probably seen footage of the most crowded routes at rush hour, when staff literally push people onto the carriages to make space, or read about young women being groped in the crush. It happens, but it is not typical. Most of the trains I rode were busy but comfortable, and I was able to get a seat.
And what makes Tokyo remarkable is that the city was almost entirely built after the original city was mostly flattened by American bombers in the Second World War. Elsewhere in the world, cities built after the war are almost invariably car-dependent. Think of Houston, Texas, which has grown from 300,000 people in the 1950s to 10 times that now. Or England’s tiny version, Milton Keynes, which is the fastest-growing city in the country. Or almost any developing world city. Since the advent of the automobile, architects and urban planners worldwide have found it almost impossible to resist building cities around roads and an assumption that most people will drive. Tokyo somehow managed not to. It rebuilt in a much more human-centric way.
It may come as a surprise that Japan is home to the world’s biggest relatively car-free city. After all, Japan is the country that gave the world Mitsubishi, Toyota, and Nissan, and exports vehicles all over the world. And in fairness, a lot of Japanese people do own cars. Overall car ownership in Japan is about 590 vehicles per 1,000 people, which is less than America’s rate of about 800 per 1,000, but comparable to a lot of European countries. On average, there are 1.06 cars per household. But Tokyo is a big exception. In Tokyo, there are only 0.32 cars per household. Most Japanese car owners live in smaller towns and cities than the capital. The highest rate of car ownership, for example, is in Fukui Prefecture, on the western coast of Honshu, one of Japan’s least densely populated areas.
And car ownership in Japan is falling, unlike almost everywhere else on Earth. Part of the reason is just that the country is getting older and the population is falling. But it is also that more and more people live in Tokyo. Annually, Japan is losing about 0.3 percent of its population, or about half a million people a year. Greater Tokyo, however, with its population of 37 million, is shrinking by less than that, or about 0.1 percent a year. And the prefecture of Tokyo proper, with a population of 14 million, is still growing. The reason is that Tokyo generates the best jobs in Japan, and it is also an increasingly pleasant place to live. You may think of Tokyoites as being crammed into tiny apartments, but in fact, the average home in Tokyo has 65.9 square meters of livable floor space (709 square feet). That is still very small—indeed, it is less than the size of the average home in London, where the figure is 80 square meters. But the typical household in London has 2.7 people living in it. In Tokyo, it is 1.95. So per capita, people in Tokyo actually have more space than Londoners.
Overall in fact, people in Tokyo have one of the highest qualities of life in the world. A 2015 survey by Monocle magazine came to the conclusion that Tokyo is the best city on Earth in which to live, “due to its defining paradox of heart-stopping size and concurrent feeling of peace and quiet.” In 2021 The Economist ranked it fourth, after Wellington and Auckland in New Zealand, and another Japanese city, Osaka. Life expectancy overall is 84 years old, one of the highest levels of any city on the planet. A good part of this has to do with the lack of cars. Air pollution is considerably lower than in any other city of equivalent size anywhere in the world. Typical commutes are, admittedly, often fairly long, at 40 minutes each way. But they are not in awful smoggy car traffic.

So how has Tokyo managed it? Andre Sorensen, a professor of urban planning at the University of Toronto, who published a history of urban planning in Japan, told me that Japan’s history has a lot to do with it. Japan’s urbanization happened a little more like some poorer countries — quickly. At the start of the 20th century, just 15 percent of Japanese people lived in cities. Now 91 percent do, one of the highest rates of urbanization in the entire world. That rapid growth meant that Tokyo’s postwar growth was relatively chaotic. Buildings sprawled out into rice paddies, with sewage connections and power often only coming later. Electricity is still often delivered by overhead wires, not underground cables. And yet somehow this haphazard system manages to produce a relatively coherent city, and one that is much easier to get around on foot or by public transport than by car.
Part of the reason, Sorensen explained to me, is just historical chance. Japanese street layouts traditionally were narrow, much like medieval alleys in Europe. Land ownership was often very fragmented, meaning that house builders had to learn to use small plots in a way that almost never happened in Europe or America. And unlike the governments there, the government in postwar Japan was much more concerned with boosting economic growth by creating power plants and industrial yards than it was with creating huge new boulevards through neighborhoods. So the layouts never changed. According to Sorensen’s research, 35 percent of Japanese streets are not actually wide enough for a car to travel down them. More remarkably still, 86 percent are not wide enough for a car to be able to stop without blocking the traffic behind it.
Yet the much bigger reason for Tokyo’s high quality of life is that Japan does not subsidize car ownership in the way other countries do. In fact, owning a car in Tokyo is rather difficult. For one thing, cars are far more enthusiastically inspected than in America or most of Europe. Cars must be checked by officials every two years to ensure that they are still compliant, and have not been modified. That is true in Britain too, but the cost is higher than what a Ministry of Transport test costs. Even a well-maintained car can cost 100,000 yen to inspect (or around $850). On cars that are older than 10 years, the fees escalate dramatically, which helps to explain why so many Japanese sell their cars relatively quickly, and so many of them end up in East Africa or Southeast Asia. On top of that there is an annual automobile tax of up to 50,000 yen, as well as a 5 percent tax on the purchase. And then gasoline is taxed too, meaning it costs around 160 yen per liter, or about $6 a gallon, less than in much of Europe, but more than Americans accept.
And even if you are willing to pay all of the taxes, you cannot simply go and buy a car in the way that you might in most countries. To be allowed to purchase a car, you have to be able to prove that you have somewhere to park it. This approval is issued by the local police, and is known as a shako shomeisho, or “garage certificate.” Without one, you cannot buy a car. This helps to explain why the Japanese buy so many tiny cars, like the so-called Kei cars. It means they can have smaller garages. Even if the law didn’t exist though, owning a car in Japan without having a dedicated parking space for it would be a nightmare. Under a nationwide law passed in 1957, overnight street parking of any sort is completely illegal. So if you were to somehow buy a car with no place to store it, you could not simply park it on the street, because it would get towed the next morning, and you would get fined 200,000 yen (around $1,700). In fact, most street parking of any sort is illegal. There are a few exceptions, but more than 95 percent of Japanese streets have no street parking at all, even during the day.
This, rather than any beautiful architecture, explains why Tokyo’s streets feel so pleasant to walk down, or indeed to look at. There are no cars filling them up. It also means that land is actually valued properly. If you want to own a car, it means that you also have to own (or at least rent) the requisite land to keep it. In rural areas or smaller towns, this is not a huge deal, because land is relatively cheap, and so a permit might only cost 8,000 to 9,000 yen, or about $75 a month. But in Tokyo, the cost will be at least four times that. Garages in American cities can cost that much too, but in Japan there is no cheap street parking option, as in much of New York or Chicago. Most apartment buildings are constructed without any parking at all, because the developers can use the space more efficiently for housing. Only around 42 percent of condominium buildings have parking spaces for residents. Similarly, even if you own a parking space, it is almost never free to park anywhere you might take your car. Parking in Tokyo typically costs 1,000 yen an hour, or around $8.50.
This is a big disincentive to driving. Sorensen told me that when he lived in Tokyo, some wealthy friends of his owned a top-end BMW, which they replaced every few years, because they were car nuts. But because they did not have anywhere to park it near their home, if they wanted to use it, they had to take public transport (or a taxi) to get to it at its garage. As a result, they simply did not use their car very much. In their day-to- day life, they used the trains, the same as everybody else, or took taxis, because that was cheaper than picking up the car. This sort of thing probably helps to explain why the Japanese, despite relatively high levels of car ownership, do not actually drive very far. Car owners in Japan typically drive around 6,000 kilometers per year. That is about half what the average British car owner drives, and less than a third of what the average American does.
Parking rules are not, however, the limit of what keeps cars out of Tokyo. Arguably, an even bigger reason is how infrastructure has been funded in Japan. That is, by the market, rather than directly by taxes. In the 1950s and ’60s, much like Europe and the United States, Japan began building expressways. But unlike in Europe and America, it was starting from a considerably more difficult place. In 1957, Ralph J. Watkins, an American economist who had been invited to advise the Japanese government, reported that “the roads of Japan are incredibly bad. No other industrial nation has so completely neglected its highway system.” Just 23 percent of roads were paved, including just two-thirds of the only highway linking Osaka, Japan’s historical economic hub, to Tokyo.
But unlike America, the idea of making them free never seemed to cross politicians’ minds, probably because Japan in the postwar era was not the world’s richest country. Capital was not freely available. To build the roads, the national government formed corporations such as the Shuto Kōsoku-dōro Kabushiki-gaisha, or Metropolitan Expressway Company, which was formed in greater Tokyo in 1959. These corporations took out vast amounts of debt, which they had to repay, so that the Japanese taxpayer would not be burdened. That meant that tolls were imposed from the very beginning. The tolls had to cover not just the construction cost, but also maintenance and interest on the loans. Today, to drive on the Shuto Expressway costs from 300 to 1,320 yen, or $2.50 to $11 for a “standard-size” automobile. Overall, tolls in Japan are the most expensive in the world — around three times higher than the level charged on the private autoroutes in France, or on average, about 3,000 yen per 100 kilometers ($22 to drive 62 miles).
What that meant was that, from the beginning, roads did not have an unfair advantage in their competition with other forms of transport. And so in Japan, unlike in almost the entire rest of the rich world, the postwar era saw the construction of enormous amounts of rail infrastructure. Indeed, at a time when America and Britain were nationalizing and cutting their railways to cope with falling demand for train travel, in Japan, the national railway company was pouring investment into the system. The world’s first high-speed railway, the Tokaido Shinkansen, was opened in 1964 to coincide with the Tokyo Olympics, with a top speed of 210 kilometers per hour. That was almost double what trains elsewhere mostly managed. From 1964 to 1999, the number of passengers using the Shinkansen grew from 11 million annually to more than 300 million.
Sorensen told me about how in the 1950s and ’60s, the trains were a huge point of national pride for the Japanese government, a bit like car industries were elsewhere. “And justifiably! It was a fantastic invention. To say we can make electric rail go twice as fast. What an achievement.” Thanks to that, the railways ministry became a huge power center in government, rather than a neglected backwater as it often had become elsewhere. In rail, the Japanese “built up expertise in engineering, in bureaucratic resources and capacities, and political clout that just lasted,” he told me. “Whereas the road-building sector was weak.” Elsewhere, building roads became a self-reinforcing process, because as more was poured into constructing them, more people bought cars and demanded more roads. That did not happen in Japan. Instead, the growth in railway infrastructure led to growth in, well, more railway infrastructure.
If you visit Tokyo now, what you will find is that the most hectic, crowded places in the city are all around the train and subway stations. The reason is that Japan’s railway companies (the national firm was privatized in the 1980s) do not only provide railways. They are also big real estate investors. A bit like the firm that built the Metropolitan Railway in the 1930s in Britain, when Japan’s railway firms expanded service, they paid for it by building on the land around the stations. In practice, what that means is that they built lots of apartments, department stores, and supermarkets near (and directly above) railway stations, so that people can get straight off the train and get home quickly. That makes the trains more efficient, because people can get where they need to go without having to walk or travel to and from stations especially far. But it also means that the railways are incredibly profitable, because unlike in the West, they are able to profit from the improvement in land value that they create.
What this adds up to is that Tokyo is one of very few cities on Earth where travel by car is not actively subsidized, and funnily neither is public transport, and yet both work well, when appropriate. However, Tokyo is not completely alone. Several big cities across Asia have managed to avoid the catastrophe (cartastrophe?) that befell much of the western world. Hong Kong manages it nearly as well as Tokyo; there are just 76 cars per 1,000 people in the city state. So too does Singapore, with around 120 per 1,000 people. What those cities have in common, which makes them rather different from Japan, is a shortage of land and a relentless, centralized leadership that recognized early on that cars were a waste of space.
Unfortunately, replicating the Asian model in countries in Europe, America, or Australia from scratch will not be easy. We are starting with so many cars on our roads to begin with, that imposing the sorts of curbs on car ownership that I listed above is almost certainly a political nonstarter. Just look at what happens when politicians in America or Britain try to take away even a modest amount of street parking, or increase the tax on gasoline. People are already invested in cars, sadly. And thanks to that, there is also a chicken-and-egg problem. Because people are invested in cars, they live in places where the sort of public transport that makes life possible for the majority of people in Tokyo is simply not realistic. As it is, constructing rail infrastructure like Japan’s is an extraordinarily difficult task. Look at the difficulties encountered in things like building Britain’s new high-speed train link, or California’s, for example.
And yet it is worth paying attention to Tokyo precisely because it shows that vast numbers of cars are not necessary to daily life. What Tokyo shows is that it is possible for enormous cities to work rather well without being overloaded by traffic congestion. Actually, Tokyo works better than big cities anywhere else. That is why it has managed to grow so large. The trend all over the world for decades now has been toward greater wealth concentrating in the biggest metropolises. The cost of living in somewhere like New York, London, or Paris used to be marginally higher than living in a more modest city. That is no longer the case. And it reflects the fact that the benefits of living in big cities are enormous. The jobs are better, but so too are the restaurants, the cultural activities, the dating opportunities, and almost anything else you can think of. People are willing to pay for it. The high cost of living is a price signal — that is, the fact that people are willing to pay it is an indicator of the value they put on it.
Especially in this post-pandemic era where many jobs can be done from anywhere, lots of New Yorkers could easily decamp to, say, a pretty village upstate, and save a fortune in rent, or cash in on their property values. Actually, hundreds of thousands do every year (well, not only to upstate). But they are replaced by newcomers for the simple reason that New York City is, if you set aside the cost, a pretty great place to live. And yet, if everyone who would like to live in a big city is to be able to, those cities need to be able to grow more. But if they continue to grow with the assumption that the car will be the default way of getting around for a significant proportion of residents, then they will be strangled by congestion long before they ever reach anything like Tokyo’s success. People often say that London or New York are too crowded, but they are wrong. They are only too crowded if you think that it is normal for people to need space not just for them but also for the two tons of metal that they use to get around.
The sheer anger of motorists might mean that banning overnight parking on residential streets proves difficult. But if we want to be bold, some of Tokyo’s other measures are more realistic. We could, for example, do a lot more to build more housing around public transport, and use the money generated to help contribute to the network. According to the Centre for Cities, a British think tank, there are 47,000 hectares of undeveloped land (mostly farmland) within a 10-minute walk of a railway station close to London or another big city. That is enough space to build two million homes, more than half of which would be within a 45-minute commute to or from London. The reason we do not develop the land at the moment is because it is mostly Metropolitan Green Belt, a zoning restriction created in the late 1940s by the Town and Country Planning Act intended to contain cities and stop them sprawling outward. But the problem with it as it works in Britain at the moment is that it does not stop sprawl — it just pushes it further away from cities, into places where there really is no hope of not using a car.
Developing the green belt too would not be popular. People have an affection for fields near their homes, and they do not necessarily want the trains they use to be even more crowded. But there are projects that show it is possible to overcome NIMBYism. In Los Angeles in 2016, voters approved the Transit Oriented Communities Incentive Program, which creates special zoning laws in areas half a mile from a major transit stop (typically, in L.A., a light rail station). This being Los Angeles, it is fairly modest. One of the rules is that the mandatory parking minimums applied are restricted to a maximum of 0.5 car parking spaces per bedroom, and total parking is not meant to exceed more than one space per apartment, which is still rather a lot of parking. But nonetheless, it does allow developers to increase the density of homes near public transport, and it has encouraged developers to build around 20,000 new homes near public transport that probably would not have been constructed otherwise. These are small but real improvements.
Ultimately, no city will be transformed into Tokyo overnight, nor should any be, at least unless a majority of the population decides that they would like it. I am trying to persuade them; for now, not everyone is as enamored with the Japanese capital as I am. But NIMBYism and other political problems can be gradually overturned, if the arguments are made in the right way, even in the most automotive cities.

Current conditions: The Atlantic hurricane season officially began today, in what’s expected to be a relatively mild year • A powerful storm with winds of up to 80 miles per hour is walloping broad swaths of millions of Australians • Temperatures in Oman are approaching 120 degrees Fahrenheit.

The United States’ offshore wind industry is, at this very moment, booming — at least in terms of the turbine arrays finally coming online in recent weeks. But there are no new projects underway as President Donald Trump pulls out all the stops to kill the industry in what I have previously called a death by a thousand cuts. That’s despite the fact that demand for electricity is soaring in the U.S. Luckily for Americans, our nation’s aging network of power grids overlaps with our northern neighbor’s. And Canada is now looking at a potential offshore wind boom. Last summer, Nova Scotia started laying the groundwork for offshore wind projects. Now Ming Yang, the world’s third-largest manufacturer of wind turbines, is considering investing in a project off Canada’s Pacific coast. The proposed project in the Hecate Strait off British Columbia would add up to 2 gigawatts of offshore wind capacity to Canada’s portfolio, according to Renewables Now. It’s part of Ming Yang’s broader push into Western markets, as my colleague Matthew Zeitlin reported last October.
Just days after New York State delayed its carbon-cutting plan and loosened the rules on how it counts greenhouse gases, California mounted its own retreat on climate goals. On Friday, Bloomberg reported that the California Air Resources Board had voted to give as much as $4 billion of free allowances to oil refiners and other industrial polluters to make compliance with the state’s 13-year-old carbon market easier. At least New York Governor Kathy Hochul “had the decency” to signal publicly that she intended to roll back the state’s climate law, said Danny Cullenward, an economist and lawyer who wrote a book on climate policy. “Here in California we do the same in private and call it climate leadership,” Cullenward wrote of California Governor Gavin Newsom and CARB Chair Lauren Sanchez in a post on Bluesky.
Kudos to the Trump administration, then, for being so open about its plans to render the SEC something that might more appropriately serve as an acronym for Salting the Earth of Climate disclosures. Last month, I told you that the Securities and Exchange Commission was reviewing a Biden-era rule requiring companies to disclose the risk climate change posed to their businesses. On Friday, the agency formally proposed eliminating the regulation. “SEC disclosure obligations should comply with the Commission’s statutory authority, be guided by materiality as the North Star, avoid the practical effect of dictating corporate behavior, and be imposed only when the expected benefits justify the likely costs and burdens,” SEC Chairman Paul S. Atkins said in a statement.
Rehlko isn’t a household name, but it used to be: The 106-year-old firm was previously called Kohler Energy. But since spinning out from the titan of American manufacturing of kitchen sinks and bathroom toilets, Rehlko has honed its business as a leading producer and installer of generators and the infrastructure to house the diesel-, gas-, or hydrogen-fired power sources. Now, I can report exclusively for this newsletter, the company is preparing to expand its factory in Wisconsin as its backlog of orders for generators to power data centers stretches beyond 13 months. In an interview on Friday, Rehlko CEO Brian Melka told me that this facility is part of a plan “to increase the size and the output of the business about four to five times, or 400% to 500%, over the next five or six years.” The Wisconsin plant is specifically designed to assemble the company’s “e-frame” product, a generator enclosure that looks like a shipping container and includes the wiring and fire suppression tools needed to safely house one of Rehlko’s proprietary generators, which provide off-grid back-up power to data centers, hospitals, and other large power users. In addition to beefing up its capacity to manufacture more generators and enclosures, the company is expanding its engineering team for larger projects in which Rehlko uses another firm’s gas turbines for full-time power generation.
“We want to maintain that competitive edge, not only to be able to deliver the product faster but also to deliver the entire solution faster,” Melka said. “This is going to significantly increase our capacity as we go into 2027 with this new facility to be able to build many more fully enclosed units. The demand keeps pushing out. We essentially sold out the capacity for that building for 2027 and 2028 before we even signed the lease.”

Unlike Russia, France, Japan, and China, the U.S. doesn’t recycle its nuclear waste. That is, until now. Roughly half a dozen companies are competing to be the first to create a beachhead for a new recycling industry in the U.S. Now one of those startups, Curio, has kicked off the pre-application process for a Nuclear Regulatory Commission permit. It’s just an inaugural step: Submitting a letter of intent to the agency to establish a docket and start providing documents to the regulator. But Curio plans to build a plant that could process up to 4,000 metric tons of used commercial light water reactor fuel per year. “The initiation of this application process marks a key and decisive moment for Curio and our nation as we commercially deploy what will be the world’s most advanced and capable used nuclear fuel recycling facility based on our game-changing NuCycle technology,” Curio CEO Ed McGinnis said in a statement, referring to the brand of the company’s reprocessing technology that was recently validated by four of the Department of Energy’s national laboratories.
South Korea, meanwhile, wants to start enriching and reprocessing its own fuel, and has garnered support from the Trump administration to do so. In the meantime, the democratic world’s most competent builder of civilian nuclear plants is doing what it does best and starting construction on a new reactor. On Friday, World Nuclear News reported that crews had poured the first concrete for Shin Hanul nuclear plant’s fourth reactor.
In January, I told you when Century Aluminum overhauled its plans to build the first new aluminum smelter in the U.S. to include an investment from an Emirati company. At the time, the Energy Department hailed the deal as a sign that Trump’s tariffs were working. On Friday, Mining.com published a feature building off a report from the advocacy group Industrious Labs that examined the recent push for new aluminum smelting in the U.S. The analysis concluded that, while 50% tariffs bolstered the sector, “access to industrial-scale electricity — and increasingly industrial-scale clean electricity — is the pain point,” said Annie Sartor, senior campaigns director at Industrious Labs. “Aluminum producers are being scooped by data centers and hyperscalers. They can simply pay more for the power.”
Among the more exciting concepts for supplying the market with cheap, clean, and affordable hydrogen is finding the stuff in naturally-formed underground reservoirs, allowing oil and gas drillers to do their thing for a green fuel. Now Oman, the Arab world’s diplomatic equivalent of Switzerland, is making progress in drilling the first wells for natural hydrogen. HyTerra, the Australian startup exploring for hydrogen in the country, told the Oman Observer that the successful pilot well boded well for tapping “one of the best source rock systems” for natural hydrogen yet discovered in the world. Given the latest heat wave in the country, the value of a fossil fuel replacement is likely becoming more obvious.
A group of energy researchers have a three-part prescription for Washington, D.C.’s exploding energy costs.
Washington, D.C. has earned an unwelcome distinction: the largest one-year electricity price increase of any state (or equivalent geographic distinction) in the U.S. Prices there are up 87% over the past five years and 26% in the past year alone, according to new data from MIT and Heatmap News’ Electricity Price Hub. The average D.C. household is now paying $55 more for power each month than it did five years ago.
In the face of this crisis, local officials have done little but blame regional markets, emphasizing the parts of recent rate increases they don’t fully control — generation charges — rather than any proactive measures they could take to offer relief to D.C. households. Meanwhile Exelon, the parent company for Pepco, D.C.’s local utility, has used the crisis to lobby state policymakers across the region for something worse — a return to utility-owned generation, which could leave consumers holding the bag for projects that run over budget or that are built for demand that never materializes.
As residents of Washington, D.C. and energy researchers who helped put together the Electricity Price Hub, we are well aware that the District cannot remake the regional electricity market on its own. But it has meaningful tools to protect ratepayers now.
To be sure, the problems D.C. faces are not entirely of its own making. Rising demand and constrained supply across the Mid-Atlantic have created a wholesale market pressure cooker.
Capacity market prices in the Pepco region, which are set through a regional auction scheme designed to ensure the grid can reliably deliver power when demand peaks, increased more than fivefold in 2025. Those costs are passing through to retail bills. As capacity has come under increasing strain, generation charges in Pepco’s standard supply service have gone up 119% — 33% in the past year alone, with yet another rate increase set to kick in on June 1.
That regional dynamic is real. But it does not absolve local officials.
Roughly 30% of Pepco’s average residential bill is made up of charges that fall squarely under D.C. jurisdiction. Distribution charges, the largest of those local components, have risen 57% over five years, and account for 20% of the total rate increase. The D.C. Public Service Commission regulates utilities in the District and must approve Pepco’s rates before they take effect. The commission, in turn, answers to the D.C. Council, the District’s legislature, which confirms its commissioners and oversees its work. These bodies should be examining every dollar of Pepco’s proposed increases. Instead, a D.C. court recently struck down the commission’s most recent rate-hike approval, finding that it had failed to sufficiently scrutinize Pepco’s request.
When a regulator is doing such a poor job that judges have to step in, that is a five-alarm signal. Yet there is a workable action plan for the Council and the PSC to rein in costs and ease the burden on D.C. households.
First, scrutinize distribution charges aggressively — that is squarely within their jurisdiction. As Pennsylvania Governor Josh Shapiro argued in his public letter to utility leaders last month, the PSC should require Pepco to justify every additional dollar of revenue requested in plain language. That means using transparent, replicable data and analysis to show why it’s needed, the alternatives considered, and how the proposed spending will concretely benefit consumers. To support this, the D.C. Council should ensure that the PSC, the Office of the People’s Council, and relevant state agencies are adequately resourced and positioned to engage with and probe Pepco’s arguments in rate proceedings.
Second, force transparency into how Pepco procures power. The public has remarkably little visibility into what makes up generation charges for the utility. For example, how much of the total cost is attributable to capacity prices, energy procurement, administrative costs, and compliance with the District’s Renewable Energy Portfolio standard? And what changes could D.C. consider to the competitive procurement process or RPS eligibility requirements to mitigate costs? Officials can’t manage what they can’t measure.
Third, attack demand by making it easier for customers to generate their own supply. High and unpredictable interconnection fees, process delays, and other administrative hurdles add unnecessary costs and contribute to the above-average cost of solar in D.C.. The D.C. Council and PSC can incentivize distribution-level solar battery deployment by cutting permitting and interconnection costs and improve cost transparency and streamline interconnection reviews to speed up the process of installing solar and storage.
None of these moves alone will reverse five years of rate increases. But together they would put real downward pressure on bills and signal that the city is serious.
What officials should reject — across the region — is Exelon’s push for utility-owned generation. In practice, it could create a generation subsidiary tomorrow. The reason it wants its rate-regulated distribution utility to do so instead is that this would let it earn a guaranteed return on costs it currently just passes through, while shifting the risk of cost overruns, schedule slips, and overbuilt capacity from shareholders to ratepayers. It would also hand the utility an information advantage over independent power producers, suppressing the competition the market relies on to keep prices honest. More profit, less risk, less competition. A great deal — for the utility.
The D.C. Council recently passed emergency legislation pausing utility disconnections for residents with unpaid balances under $1,000. That is a humane stopgap as we head into summer, but it is not a strategy. Neither is anything that has been proposed during the current mayoral race, in which leading candidates have attacked each other’s records instead of offering a plan to lower bills.
D.C. residents do not need more blame-shifting. The choice in front of the council and the PSC is concrete: Scrutinize what is in their jurisdiction, force the transparency they have the authority to require, accelerate the cheapest sources of new supply, and refuse to subsidize a Pepco business model that turns ratepayers into the underwriters of utility risk. That is the test of whether they meet this moment seriously.
On Thea Energy’s $100 million Series B, plus more of the week’s big money moves.
Nuclear is once again a dominant theme this week, with fusion startup Thea Energy landing a $100 million Series B that will help it expand its magnet manufacturing capabilities. While $100 million is nothing to scoff at, it somehow sounds modest alongside some of this year’s other deals, which include a $450 million Series A for Inertia Enterprises and $240 million for Shine Technologies. This week also brought the news that small modular reactor startup Newcleo plans to go public via SPAC later this year, bringing to mind the exuberance of the 2021 SPAC boom, in a deal expected to net a cool $429 million.
Elsewhere, gridtech company Utilidata raised fresh capital after (surprise!) pivoting to the data center market, while a standalone battery storage developer and operator is betting there’s still plenty of money to be made in the increasingly crowded ERCOT market.
Thea Energy officially joined the growing ranks of fusion companies to surpass $100 million in total funding this week, raising a $100 million Series B round led by the U.S. Innovative Technology Fund to scale its magnet manufacturing operations as it targets a demonstration reactor by 2030. Thea is a part of the Department of Energy’s Milestone-Based Fusion Development Program, which seeks to accelerate efforts for commercial fusion power. In January, the DOE certified Thea’s preconceptual pilot plant design, making it the first of the program’s eight awardees — who will split $46 million in federal funding — to see its reactor architecture validated.
Unlike many top-funded fusion startups, which are building donut-shaped tokamak reactors, Thea Energy is betting on a stellarator design. Traditional stellarators resemble a helical tokamak, which require manufacturing and installing dozens of huge, twisted magnets, but Thea’s approach deviates from the norm. Instead, it relies on hundreds of small, planar magnets arranged in the more familiar donut-shaped configuration, which the company’s artificial intelligence software controls individually. That enables Thea to create the same complex magnetic field within a far simpler and more manufacturable shell.
Thea plans to use the new capital to build a second facility in New Jersey to complement its existing lab and to double its headcount as it seeks a site for its demo reactor later this year. The startup is aiming to bring its subsequent commercial pilot online by 2034, on par with the timeline laid out by fusion industry leader Commonwealth Fusion Systems. According to Gaetano Crupi, USIT founder and billionaire investor Thomas Tull “believes the stellarator is the right architecture for commercial fusion, and Thea Energy is the company that makes it commercially viable.” As Crupi put it in a press release, that’s because “Thea Energy’s breakthroughs shift complexity from precision mechanical fabrication to software-defined controls.”
Newcleo is the latest small modular reactor startup seeking a quick pathway to the public markets via a SPAC merger, announcing plans to list on the Nasdaq in the second half of the year after merging with a blank-check firm. The deal values the European fuel and reactor developer at $2.4 million, and is expected to deliver about $429 million in fresh capital. It comes just months after Newcleo raised $88 million in a growth financing round as the company expands into the U.S. market while continuing to fund projects across Europe.
Newcleo stands out in the crowded SMR field through its fuel and cooling strategy. It plans to run its 200-megawatt reactors on recycled fuel made from nuclear waste products like recovered plutonium and depleted uranium, and cool its reactors with liquid lead rather than water. Because liquid lead has such a high boiling point, lead-cooled reactors can operate at atmospheric pressure, reducing the need for the complex, high-pressure systems used in conventional nuclear plants and potentially improving safety along the way.
The company has already raised over $760 million to date, and CEO Stefano Buono told the Wall Street Journal that the pending SPAC could carry it through 2028 or 2029. Even that won’t be enough, however, for Newcleo to reach its target of opening a fuel factory by 2031 and bringing a commercial reactor online the following year. Not to mention that SPACs — a once rare go-to-market strategy — have a checkered history in the SMR industry. After NuScale went public via SPAC in 2022, its flagship project collapsed, taking its stock down with it and underscoring the risks that pre-revenue companies face when their early failures unfold in the public markets. On the other hand, shares of Sam Altman-backed startup Oklo’s have surged since it went public via SPAC in 2024, reaching a market cap over $11 billion, though it also has yet to build a reactor.
Newcleo’s capital push may also be tied to its strategic partnership with Oklo, as it has preliminary plans to invest up to $2 billion to develop advanced nuclear fuel facilities in the U.S. in partnership with the SMR pioneer. Earlier this week, the DOE selected Oklo — and by extension, Newcleo — to enter “advanced negotiations” to receive surplus weapons-grade plutonium for use in reactor fuel.
What’s that I hear? Another climate tech company has pivoted to the data center market? While Utilidata — an artificial intelligence-powered gridtech company — initially set out to give utilities granular insight into household-level electricity usage and grid data, it’s now raised a $40 million extension round to accelerate its shift into the data center market. As I wrote following last year’s initial $60 million tranche of Series C funding, Utilidata initially set out to get its hardware module inside residential smart meters — which it managed to do at pilot scale — to enable faster fault detection and eventually even automate load management at the household level.
Now, Utilidata is taking this same principle and applying it to the booming data center market, where so many climate tech companies are finding their first customers. The company developed its AI platform in collaboration with Nvidia, installing its modules on server racks to help data centers optimize power allocation across its facility. The company says it measures power consumption a million times per second, such that if usage on one rack is low, it can reroute electricity to parts of the data center that need it. Much like electric grids, data centers also overbuild their capacity to ensure they can handle sudden spikes in demand or hardware failures. Utilidata wants to tap into that headroom by managing power flow in real time.
Utilidata’s first commercial data center deployment is set to go live next month in Montreal in partnership with European AI cloud provider NexGen Cloud, with the startup targeting a 50% increase in the data center’s usable processing power. It also plans to use this latest funding to increase headcount by 25% this year as it builds out operations at its new Ann Arbor headquarters, which opened in February.
In some later-stage funding news, battery energy storage developer, owner, and operator Goshe Energy Storage just secured up to $40 million in strategic financing from S2G investments. As I wrote last week, S2G recently raised a $1 billion fund aimed at helping growth-stage companies commercialize, though this latest commitment actually comes from a different arm of the firm — its Special Opportunities team. This division focuses on non-dilutive financing, in this case providing Goshe with a HoldCo loan backed by the company’s portfolio of energy storage projects. Rather than lending to a specific project, a HoldCo loan gives Goshe flexible capital that can be used to fund its broader growth.
Founded in 2022, Goshe specializes in acquiring late-stage battery storage projects and getting them over the finish line by securing capital and managing the construction process into commercial operations. Thus far, all of its announced projects are in Texas’ ERCOT electricity market. Alongside this financing announcement, Goshe said that its first project — a 100-megawatt battery storage plant in Bexar County, Texas — is now fully operational after securing $288 million in project financing. The company also expects to bring its second project, a 180-megawatt storage facility, online in the following few months, with two additional ERCOT projects slated to begin construction later this year.
This funding is the latest sign that infrastructure investors have grown comfortable backing battery energy storage projects, with a record 24.3 gigawatts of new battery storage capacity projected to come online in the U.S. this year alone. The wholesale ERCOT market, however, is no longer the guaranteed moneymaker that it was just a few years ago. Between January 2024 and January 2026, ERCOT more than tripled its battery storage capacity, driving battery revenues down as the market has become increasingly crowded. In this landscape, there may be a growing number of stranded projects for Goshe to acquire, though it’ll also have to be increasingly selective.
