  • Britain's Car Industry: From World Leader To Net Zero Casualty

    Britain's Car Industry: From World Leader To Net Zero Casualty

    Authored by Jake Scott via the Foundation for Economic Education (FEE),

    Britain was once a giant of car manufacturing. In the 1950s, we were the second-largest producer in the world and the biggest exporter. Coventry, Birmingham, and Oxford built not just cars, but the reputation of an industrial nation; to this day, it is a source of great pride that Jaguar–Land Rover, a global automotive icon, still stands between Coventry and Birmingham. By the 1970s, we were producing more than 1.6 million vehicles a year.

    Today? We have fallen back to 1950s levels. Last year, Britain built fewer than half our peak output—800,000 cars, and the lowest outside the pandemic since 1954. Half a year later, by mid-2025, production has slumped a further 12 percent. The country that once led the automotive revolution is now struggling to stay afloat, and fighting to remain relevant.

    This is why the news that BMW will end car production at Oxford’s Mini plant, shifting work to China, is so damning, bringing this decline into sharp focus. The Mini is not only a classic British car; Alec Issigonis’s original design made it an international icon. For decades, the Mini has been the bridge between British design flair and foreign investment. Its departure leaves 1,500 jobs at risk at a time when the government is desperate to fuel growth and convince a wavering consumer market that there is no tension between industrial production and Net Zero goals.

    It’s a bitter reminder that we in Britain have been here before: letting an industrial crown jewel slip away.

    The usual explanations will be offered: global competition, exchange rates, supply chains. All true, in the midst of a global trade war that is heating up and damaging major British exports. But such a diagnosis is incomplete. The truth is that Britain’s car industry is being squeezed by a mix of geopolitical realignment and government missteps.

    The car industry has become the frontline of a new trade war. Washington has already moved aggressively to shield its own firms: the Inflation Reduction Act offers vast subsidies for US-made EVs and batteries, an unapologetic attempt to onshore production, and something that became a flashpoint of tension in Trump’s negotiation with the EU in the latest trade deal. On the production side, the Act has poured billions into US manufacturing: investment in EV and battery plants hit around $11 billion per quarter in 2024.

    Ripples have been sent across the world in the US’s wake: Europe, faced with a flood of cheap Chinese EVs, has imposed tariffs of up to 35 percent after an anti-subsidy investigation. Talks have even turned to a system of minimum import prices instead of tariffs. Unsurprisingly, China has threatened retaliation against European luxury marques, while experts warn the tariffs may slow the EU’s green transition by raising prices.

    This is no longer a free market: cars are treated as strategic assets, the 21st-century equivalent of shipbuilding or steel. Whoever controls the supply chains, particularly for EV batteries and the mining of lithium, controls not only the future of the industry but an important lever of national power.

    The results are visible. In July 2025, Tesla’s UK sales collapsed nearly 60 percent, while Chinese giant BYD’s deliveries quadrupled. Europe responded by talking up new tariffs. Britain did nothing. In this asymmetric contest, our market risks becoming a showroom for foreign producers—subsidizing both sides of the trade war without defending our own.

    The real danger is not simply that Britain loses factories—that would be lamentable, but new industries crop up all the time. The danger comes if Britain misreads the geopolitics of the moment. Policymakers assume that globalization still works on liberal lines, when in reality industrial competition has become nakedly political.

    If the government continues to approach this as a morality play about “green obligations” rather than a contest of state-backed strategies, Britain will find itself outmaneuvered by rivals who are willing to fight dirty. The naivety of this government in the geopolitical realm is already on show—all it takes is an unscrupulous actor to take advantage.

    Meanwhile, Britain’s car industry is being crushed under the weight of its own government’s Net Zero agenda.

    The most obvious domestic distortion comes from the government’s own Net Zero policies. Ministers have decreed that petrol and diesel cars must disappear by 2035, with quotas forcing manufacturers to sell ever-higher proportions of electric vehicles long before customers are ready—a decision enforced by the current government, but made by its predecessor.

    On paper, it looks like progress. Nearly one in five new cars sold in Britain last year was electric. In June 2025, the figure briefly touched 25 percent. But strip out fleet purchases and subsidies, and private demand is anemic. Only about one in ten EVs was bought by a private household.

    For manufacturers, the economics are even tougher. Retooling factories for EVs requires billions in investment. Yet the batteries—the heart of the new supply chain—are overwhelmingly produced abroad. China commands over 70 percent of global output, Europe is building dozens of gigafactories, and Britain has just one small facility. No wonder BMW decided that Oxford was not the place to build the future Mini, forced out by the pressures its own government applied.

    The intention may be laudable, but the execution is not. Policy is not aligning with either consumer demand or industrial capacity.

    Meanwhile, there are very few actual incentives for consumers to switch over: charging network coverage remains patchy; electric models cost £35,000 or more; and consumers already pay the highest energy bills in Europe. The market is being pulled one way by ministers, another by reality.

    We’ve been here before. After the war until the end of the 1970s, in the mislabeled “Post-war consensus,” governments tried to micromanage the car industry’s future through subsidies, planning boards and nationalization. The outcome was not at all surprising: British cars and their manufacturers were known for poor quality, collapsing output, and eventual irrelevance.

    The risk now is that Net Zero becomes another form of overreach, with governments trying to enforce an industrial transformation without the underlying conditions in place.

    Cleaner technologies may be necessary, and the automotive industry has already made huge strides in progress. The irony is that Britain has the engineering talent and know-how to deliver them, but when the state insists on timelines and quotas while failing to invest in the supply chain or shield producers from unfair competition, the result is predictable: decline.

    Britain could chart a smarter course. That means lowering energy costs for industry, reforming planning so that battery plants can be built at speed, and ensuring that rules are competitive rather than punitive. Before all of this, it means recognizing that the route to prosperity is getting the government out of the way.

    Most importantly, though, it requires recognizing that the car industry is now a geopolitical contest. The US, EU, and China all understand this.

    The decline of British car making is not just about economics. These plants are part of our cultural DNA. The Mini isn’t just a car; it’s a symbol of Britain itself. Small, ingenious, stylish, and stubbornly practical. To lose it to Net Zero dogma is an act of national self-harm and a loss of prestige.

    Oxford’s closure is not an isolated blow. It is a warning. We can either learn from our own history and build policy around industrial reality, or we can keep writing the obituary of British manufacturing.

    Because if Britain continues down the current path, the story of the Mini may become the story of the entire industry: once world-leading, now outsourced, and soon extinct.

  • Geothermal is too expensive, but Dig Energy’s impossibly small drill rig might fix that

    Geothermal is too expensive, but Dig Energy’s impossibly small drill rig might fix that

    On a farm near Manchester, New Hampshire, I was recently treated to a gusher of dirty water, not exactly the sort of thing that most startups will show a reporter. But for Dig Energy, the mud is a feature, not a bug, of its compact drilling rig. 

    The startup, which has been operating in stealth for the last five years, developed the water-jet drilling rig in an effort to make geothermal heating and cooling so inexpensive that it will displace fossil fuel boilers and furnaces. The rig is central to that, promising to slash drilling costs by up to 80%.

    On Tuesday, Dig Energy emerged with $5 million in seed funding, TechCrunch has exclusively learned. The round was led by Azolla Ventures and Avila VC with participation from Baukunst, Conifer Infrastructure Partners, Koa Labs, Mercator Partners, Drew Scott, and Suffolk Technologies.The Dig Energy team stands before a green barn wall.From left: Vice President of Engineering Dan Jepeal, CEO Dulcie Madden, and CTO Thomas Lipoma.Image Credits:Dig Energy

    Heating and cooling represent about a third of all energy use in the U.S., and in data centers, the figure can be as high as 40%. Geothermal can slash HVAC energy use while also saving grid operators up to $4 billion annually. To help stabilize its creaking electrical grid, the U.S. needs to drill 6 million feet of geothermal borehole daily through 2050, according to the Oak Ridge National Laboratory.

    But geothermal doesn’t come cheap, at least not at first.

    “In the United States, geothermal has been 1% of building installations for decades,” Dig co-founder and CEO Dulcie Madden told TechCrunch. That’s despite the technology’s low operating costs. “It’s really just because upfront cost is so, so, so expensive.”

    There are two main flavors of geothermal: Enhanced geothermal drills down thousands or tens of thousands of feet. Companies like Fervo and Quaise that are drilling that deep are tapping very hot temperatures — usually in the hundreds of degrees — to generate electricity. The other, shallow geothermal, which is what Dig is focused on, is usually limited to hundreds of feet. At those depths, the ground maintains a consistent temperature year-round, which is perfect for heating and cooling residential and commercial buildings.

    In shallow geothermal, pipes carry water underground where it transfers heat to or from the earth. In the summer, it dumps excess heat, and the chilled water returns to the surface to cool a building. In the winter, it absorbs heat to warm it.

    Installing the ground loop, as the underground piping is called, represents around 30% of the total cost of a ground-source heat pump and is one of the main reasons the technology remains more expensive than conventional heating and air-conditioning systems. Tackling those costs was high on Dig’s list. 

    “When we were getting started, we were like, can we build a lower-cost drill?” Madden said.

    Madden and her co-founder, husband Thomas Lipoma, began exploring the space five years ago after winding down their previous startup, Rest Devices. They soon stumbled upon old research describing how to use water jets instead of traditional cutting bits to bore into the earth.

    But while there had been plenty of research into the technology, it still wasn’t ready for prime time. “A lot of the drilling technology has trickled down from oil and gas,” Madden said. Translation: It tends to be large, expensive, and overpowered for something like geothermal at the depths Dig is plumbing.A white shed with green doors casts a shadow on soil and grass.This white shed is where the earliest Dig Energy prototypes were designed and manufactured.Image Credits:Tim De Chant

    Dig has spent years refining the design of its rig, drilling test holes near its offices in New Hampshire. They’ve drilled through soil, gravel, clay, sand, and a range of different rock types, including sandstone, limestone, granite, slate, and shale. The team showed me test blocks of some very dense rock with neat holes blasted through the middle.

    Today’s geothermal drill rigs can do the same, but they’re massive by comparison. The most commonly used versions sit on the back of large trucks. For easily accessible sites, they work well enough. But they are unable to squeeze through side lots into people’s backyards, and at crowded commercial building sites, they occupy precious free space.

    While Dig’s prototype isn’t ready for commercial use, what I saw was substantially smaller than widely used geothermal drill rigs. The holes it drills are also straighter than those made by traditional rigs. Together, those two details mean that Dig’s bore holes can be placed closer together, a boon for any developer. 

    When it’s ready for its first commercial pilots — something this seed round will help accomplish — Dig’s rig will grow in size slightly, but it won’t require the large, double-axle trucks that currently dominate the industry.

    The company is planning to sell the devices to drillers, giving them another option for existing projects and potentially opening avenues to new ones. Other companies are exploring the technology, too. 

    “We shouldn’t have to require people to buy a $2 million rig; it should be something that’s lower cost where they can get into the business,” Madden said. “Geothermal should be in 100% of buildings. It’s in 1% of buildings. So how do we close the 99%?” she added. “It’s effectively an untapped market.”
