King Charles III has been called “the real deal” — and also a climate fraud.

At the very least, you’ve got to admit — the “Green King” has a nice ring to it.
This Saturday, for the first time in 70 years, Britain will formally crown a new sovereign, setting off a three-day weekend of celebrations that will cost taxpayers a rumored $125 million. But while King Charles III is tied with his wife, Camilla, as Americans’ second-least-favorite royal — behind only the notorious Prince Andrew — his ascension has also drawn praise from climate activists and historians worldwide, who’ve dubbed him Britain’s “environmentalist king-in-waiting.”
Charles’ more than a half-century of environmental activism will undoubtedly be tempered by what The New Yorker calls the monarchical “convention to not publicly register his own views on matters of political policy, and, indeed, to accept the policies of the government.” But his credentials as the once and future Green King of the United Kingdom are also mixed; for every illegally fished Patagonian toothfish he’d defended in the name of “the poor old albatross,” there’s also a wind turbine he’s blasted as a “blot.”
Here’s an overview of Charles’ mixed green bona fides, in passages from 10 helpful articles from around the web.
It may be tempting to think of the new King, with his bespoke Savile Row suits, Edwardian manners, and royal retinue, as an icon of a previous age. But his speeches, books, and projects do suggest a man ahead of his time. He was advocating concepts such as the circular economy and natural capital years before they captured the public’s imagination, and he’s clearly followed his own principles, converting his farm to organic practices more than 30 years ago.
“Some of these ideas were radical and literally decades ahead of their time. Some you could reprint today and they would be very much of the moment. It’s hard to overstate the role he played in putting these subjects on the agenda,” says Tony Juniper, chair of Natural England, a fellow with the University of Cambridge Institute for Sustainability Leadership, and former executive director of Friends of the Earth and president of the Wildlife Trusts.
From “Prince Charles Was an Environment Radical. What Happens Now He’s King?” by Jonathan Manning for National Geographic, Sept. 23, 2022
[...The] 73-year-old monarch has dedicated a large part of his life to doing something about the environmental issues that, as a youth, so occupied his mind. He has been an outspoken supporter of sustainability, organic farming, renewable energy, and biodiversity. He’s encouraged others to rethink urban design and corporate production. He skips meat a few days a week. His vintage Aston Martin runs on surplus wine and excess cheese whey. Clarence House, where he lived in London as the Prince of Wales, has solar panels. Balmoral, the summer home of the Royal Family in Aberdeenshire in Scotland, features hydroelectric turbines and biomass boilers. And at last year’s COP26, the king warned world leaders that “after billions of years of evolution, nature is our best teacher” when it comes to reducing emissions and capturing carbon, noting that “restoring natural capital, accelerating nature-based solutions, and leveraging the circular bioeconomy will be vital to our efforts.”
[...Unlike] other world figureheads touting climate issues, when it comes to actually believing in the need to tackle climate change, King Charles is the real deal, argues Piers Forster, professor of climate physics at the University of Leeds and a trustee of the United Bank of Carbon.
From “What Charles the ‘Activist King’ Means for the Climate” by Tom Ward for Wired, Sept. 14, 2022
Charles — like his father, Prince Philip, before him — has at times waded into the sticky morass of population growth. In a speech given at the Sheldonian Theater at Oxford University in 2010, then-Prince Charles noted: “When I was born in 1948, a city like Lagos in Nigeria had a population of just 300,000; today, just over 60 years later, it is home to 20 million.”
With population increasing rapidly in Mumbai, Cairo, Mexico City, and cities in other developing countries around the world, Charles said Earth cannot “sustain us all, when the pressures on her bounty are so great.”
[…] There may seem to be a simple logic in laying the blame for climate change on global population, which is now inching toward 8 billion. But there is a long and fraught history of thinkers in developed countries critiquing population growth in developing ones. Betsy Hartman, a professor emerita of development studies at Hampshire College, has said, “In this ideology of ‘too many people,’ it’s always certain people who are ‘too many.’”
From “The Many Paradoxes of Charles III as ‘Climate King’” by Shannon Osaka for The Washington Post, Sept. 13, 2022
[...There] has long been respect for Charles among Indigenous people stretching back more than two decades to April 2001, when the prince traveled to Saskatchewan for a Cree ceremony that bestowed upon him the name Kīsikāwipīsimwa miyo ōhcikanawāpamik, or, “The Sun Watches Over Him in a Good Way.”
Our new monarch has made efforts to visit with Canadian Indigenous leaders in subsequent trips. In 2019, he invited [Perry Bellegarde, former national chief of the Assembly of First Nations] to London and [asked] him to be a part of the Sustainable Markets Initiative, which attempts to push the private sector to make the transition to low-carbon operations.
Charles even consulted with First Nations elders over Zoom during the pandemic to talk about elders’ traditional knowledge.
“He’s got it in terms of sustainable development — that we’re all connected to the land and to the water, and that what affects the animals affects us, and what affects the plants affects us, and what affects the water affects us as human beings,” Bellegarde said.
“I teased him one time in a meeting: ‘I swear to goodness, your Majesty, that you were First Nations in another life.’”
From “Call Him the Green King. Charles Will Have an Environmental Agenda. How Far Can He Push It?” by Allan Woods for The Toronto Star, April 30, 2023
Charles has never acknowledged the monarchy’s full responsibility for the climate crisis. Asked by the BBC last year if the U.K. was doing enough to combat climate change, he replied: ”I couldn’t possibly comment.” And while Charles has acknowledged the general injustice of the monarchy’s colonial legacy, he has not connected that legacy to growing climate injustice around the world.
Climate justice activists from colonized nations say this connection is important, because the very institution that gives Charles a powerful platform to speak on climate change is responsible for creating global crisis conditions in the first place. To truly be considered a “climate king,” they say, Charles would have to not only acknowledge the climate harm done by the monarchy, but take steps to repair it.
From “Stop Calling Charles the ‘Climate King’” by Emily Atkin for Heated, Sept. 14, 2022
The Sustainable Markets Initiative (SMI), which Charles launched in 2020 when he was Prince of Wales, granted BP a “Terra Carta Seal” even though the oil and gas giant had failed to achieve a top score from the sustainability ranking company assessing applicants for the awards.
[…] Clive Russell, a spokesperson for Ocean Rebellion, an activist group that spun out of Extinction Rebellion, said giving BP a seal undermined SMI’s credibility: “How can an initiative co-founded by a world-renowned polluter like BP – a company currently investing £300m in renewables and £3.8bn in new oil and gas – be taken seriously? The SMI should be disbanded. Those involved should hang their heads in shame. This is blatant greenwashing.”

On the eve of today’s Countryside Alliance march in London, it was revealed that the heir to the throne wrote to Tony Blair expressing anger at the government for pursuing plans to outlaw the bloodsport in England.
It is understood the Prince, a passionate hunt supporter, told Blair that he “would not dare attack an ethnic minority in the way that supporters of fox hunting were being persecuted.”
From “Prince: I’ll Leave Britain Over Fox Hunt Ban,” by The Scotsman, Sept. 22, 2002
Addressing a conference of conservationists at St James’s Palace in London, the Prince of Wales announced a meeting of heads of state to take place this autumn in London under government auspices to combat what he described as an emerging, militarised crisis.
“We face one of the most serious threats to wildlife ever, and we must treat it as a battle — because it is precisely that,” said Charles. “Organised bands of criminals are stealing and slaughtering elephants, rhinoceros, and tigers, as well as large numbers of other species, in a way that has never been seen before. They are taking these animals, sometimes in unimaginably high numbers, using the weapons of war — assault rifles, silencers, night-vision equipment, and helicopters.”
From “Prince Charles Calls for a War on Animal Poachers” by Fiona Harvey for The Guardian, May 21, 2013
“[Charles] is understood to be strongly opposed to onshore wind turbines that rise higher than 100 metres because of their visual impact, and none have been erected on land owned by the Duchy of Cornwall, the £700m estate that provides him with a private income. He has lobbied government officials to subsidize other renewable energy sources and is reported to believe that if windfarms should be built at all, they should be far out at sea.
[...] In the past few years, the crown estate has signed a 25-year lease with the renewable energy company RWE for turbines at Little Cheyne Court windfarm in Kent and has agreed lease options with Renewable Energy Systems, which wants to erect 15 turbines in Carmarthenshire, with RWE npower for four turbines in Powys, and with E.ON for 17 turbines on the Billingborough estate in Lincolnshire
[...] “It is hypocrisy,” said Leanne Wood, a candidate for the Plaid Cymru leadership who is campaigning for Welsh energy independence. “[The prince] stands to benefit from wind projects on land in Wales, but opposes them himself. If that is his position there shouldn’t be windfarms on crown estate land.”
From “Prince Charles To Get Funding From ‘Blot on the Landscape’ Windfarms” by Robert Booth for The Guardian, Feb. 28, 2012
From now on, what the King says is less important than what he is seen to do. He now runs a multibillion-pound private corporation and has one of the world’s greatest personal fortunes. How our billionaire king spends his money and what he does with his vast properties and land holdings may fundamentally change the way Britain sees itself – and how the world regards us.
[... He] could start his green reforms of the monarchy by publicly divesting the institution of all fossil fuel interests [...] He could [offer] to the state or the National Trust most of his cold, largely empty, useless castles, palaces and mansions, such as Balmoral and Sandringham. He could then slash the estimated £90,000-a-month heating bills of any that are left – Windsor or Sandringham, for example – by investing heavily in heat pumps, solar power and insulation and then switching his bills to renewable energy providers such as Ecotricity or Good Energy.
[...He could] clear out the old rollers and Bentleys, go entirely electric, and take to bicycles and rail like other modern monarchies [...] If he was brave and fair-minded he could offer the 16 private hectares (39 acres) of Buckingham Palace to London as a new public park [...]
[...] Charles could happily dispose of most of the many thousands of great diamonds, rubies, and other jewels that have been handed personally to royalty over 200 years without anyone caring. The billions of pounds raised from such a sale could be used to establish academies of sustainable farming or permaculture in the Commonwealth countries from which most jewels were looted in colonial times and many of which are still struggling to feed themselves.
Aside from shedding most of his relations, abandoning archaic British empire medals, and generally living less lavishly, he could start hosting vegetarian banquets and end hunting on all royal lands.
At which point, he could do the decent thing and abolish himself.

A conversation on FEMA, ICE, and why local disaster response still needs federal support with the National Low-Income Housing Coalition’s Noah Patton.
Congress left for recess last week without reaching an agreement to fund the Department of Homeland Security, the parent agency of, among other offices, Customs and Border Protection, Immigration and Customs Enforcement, and somewhat incongruously, the Federal Emergency Management Agency. Democrats and Republicans remain leagues apart on their primary sticking point, ending the deadly and inhumane uses of force and detention against U.S. citizens and migrant communities. That also leaves FEMA without money for payroll and non-emergency programs.
The situation at the disaster response agency was already precarious — the office has had three acting administrators in less than a year; cut thousands of staff with another 10,000 on the chopping block; and has blocked and delayed funding to its local partners, including pausing the issuance of its Emergency Management Performance Grants, which are used for staffing, training, and equipping state-, city-, and tribal-level teams, pending updated population statistics post deportations.
Even so, FEMA remains technically capable of fulfilling its congressionally mandated duties due to an estimated $7 billion that remains in its Disaster Relief Fund. Still, the shutdown has placed renewed scrutiny on DHS Secretary Kristi Noem’s oversight of the agency. It has also elevated existing questions about what FEMA is doing alongside CBP and ICE in the first place.
To learn more about how the effects of the shutdown are trickling down through FEMA’s local operations, I spoke with Noah Patton, the director of disaster recovery at the National Low-Income Housing Coalition, which has publicly condemned the use of FEMA funding as a “political bargaining chip to allow ICE and CBP to continue their ongoing and imminent threats to the areas where they operate.”
When asked for comment, a FEMA spokesperson directed me to a DHS press release titled “Another Democrat Government Shutdown Dramatically Hurts America’s National Security.”
The conversation below has been edited for length and clarity.
Why is the DHS shutdown an issue you care about as a low-income housing organization? What are the stakes?
How the country responds to and recovers from disasters is inextricably linked to the issue of affordable housing. Often, households with the lowest incomes are in areas with the highest risk of disaster impacts. Our system has a lot of cracks in it. If you don’t have a rainy day fund for such things; if you’re someone who is not fully insured; if you have non-permanent employment — when disasters occur, you’re going to be hit the hardest. At the same time, you’ll receive the least assistance.
That not only exacerbates existing economic issues but also reduces the affordable housing stock available to the lowest-income households, as units are physically removed from the market when they’re destroyed or damaged by disasters.
What disasters are we talking about specifically at the moment? Are reimbursements for, say, the recent winter storms impacted by the shutdown?
Typically, when the [Disaster Relief Fund] is low, FEMA will implement critical needs funding. It pauses reimbursements for non-specific disaster-response projects and reallocates funds to preserve operational capacity for direct disaster response. That hasn’t happened yet because the DRF has sufficient funds. On the administrative end, reimbursements will be processed as we go along.
Is there anything you’re concerned about in the short term with regard to the DHS shutdown? Or has NLIHC pushed for the depoliticization of FEMA funding because of the cascading effects for the people you advocate for?
FEMA is okay as of right now. The need to stop ICE and CBP and the violence in communities across the country is taking precedence. We appreciate Congress’ interest in ensuring FEMA is adequately funded, but the DHS appropriations bill is not the only vehicle for providing FEMA funding. That’s why we’ve been pushing for a disaster-specific supplemental spending bill. That bill could also have longer-term assistance under HUD for places like Alaska [following Typhoon Halong], Los Angeles [following the January 2025 wildfires], and St. Louis [following the May 2025 tornado].
Maybe you’ve already answered my next question: How has NLIHC been navigating the tension between condemning ICE and CBP, while at the same time pushing for FEMA funding?
We have been big supporters of the House’s FEMA Act: the Fixing Emergency Management for Americans Act. It’s a bill that would remove FEMA from DHS, reestablish it as an independent agency as it was prior to 2003, and implement reforms to expand access to federal assistance for households with the lowest incomes after disasters. We’ve been supporters of that bill since it came out.
I’d also say, in the short term, I don’t see a huge amount of impact on the disaster response and recovery systems. It’s worth pausing on that, given everything going on with ICE and CBP.
What else is on your minds right now at NLIHC?
Much of the work we’re doing stems from the rapid, forced decentralization of the federal government’s emergency management capability — because emergency response and recovery now falls to the states. But many states lack robust disaster response and recovery programs. The state of Oklahoma, for example — I think their Emergency Management Office is 90% federally funded.
The administration’s pull-back of state-level emergency management performance grants and the coordination FEMA was providing on that will get the ball rolling; as we’ve seen in other disasters, the ball ends at households with the lowest incomes being the most impacted. We’re trying to head that off by coordinating advocates at the state and local levels to work with their local governments and facilitate more robust conversations on emergency management and related programs. A good example of that would be what we’re seeing in Washington State after the flooding from the atmospheric rivers. They have not received a disaster declaration from FEMA, so they’re not receiving federal assistance, but people are experiencing homelessness due to those floods. We’re working with folks there to craft programs that ensure that, in the absence of federal assistance, some form of aid continues.
For many years, the federal government was heavily involved in emergency management and served as the main coordinator. They were the source of the vast, vast, vast majority of funding. Now we’re looking toward a world where that’s less true, and where state-level mechanisms will be all the more important. Even if the FEMA Act is passed, it encourages state-level systems to emerge for responding to and recovering from disasters. We’re adding a focus to that state-level work that we didn’t necessarily need before.
The Trump administration has justified its defunding of FEMA by saying, “Well, disaster response is local, so this should be the responsibility of the states.” But like you were saying, places like Oklahoma get all their support from the federal government to begin with.
They always say, “Disaster response is local” because operationally, it needs to be. You’re not going to have a FEMA guy parachute in and start telling the local firefighters and cops what to do; that’s best handled by the folks who are on the ground and are familiar with their communities.
But it’s wrong to say, “If all disaster response is local, then why are we even involved?” FEMA provides the coordination and additional resources that are pivotal. Federal resources are allocated to local officials to respond to the disaster. The salaries of all those local emergency managers — at least, a high percentage of them — that money comes from the feds.
If the shutdown continues much longer, would that be another impact: local emergency managers not receiving their salaries?
The grant-making fight is separate. The administration is trying to slow down the flow of [emergency management preparedness grants] to state governments. Several states have filed high-profile lawsuits to obtain the grants that the federal government arbitrarily paused. Regardless of any shutdown, that will still be an issue.
On Georgia’s utility regulator, copper prices, and greening Mardi Gras
Current conditions: Multiple wildfires are raging on Oklahoma’s panhandle border with Texas • New York City and its suburbs are under a weather advisory over dense fog this morning • Ahmedabad, the largest city in the northwest Indian state of Gujarat, is facing temperatures as much as 4 degrees Celsius higher than historical averages this week.
The United States could still withdraw from the International Energy Agency if the Paris-based watchdog, considered one of the leading sources of global data and forecasts on energy demand, continues to promote and plan for “ridiculous” net-zero scenarios by 2050. That’s what Secretary of Energy Chris Wright said on stage Tuesday at a conference in the French capital. Noting that the IEA was founded in the wake of the oil embargoes that accompanied the 1973 Yom Kippur War, the Trump administration wants the organization to refocus on issues of energy security and poverty, Wright said. He cited a recent effort to promote clean cooking fuels for the 2 billion people who still lack regular access to energy — more than 2 million of whom are estimated to die each year from exposure to fumes from igniting wood, crop residue, or dung indoors — as evidence that the IEA was shifting in Washington’s direction. But, Wright said, “We’re definitely not satisfied. We’re not there yet.” Wright described decarbonization policies as “politicians’ dreams about greater control” through driving “up the price of energy so high that the demand for energy” plummets. “To me, that’s inhuman,” Wright said. “It’s immoral. It’s totally unrealistic. It’s not going to happen. And if so much of the data reporting agencies are on these sort of left-wing big government fantasies, that just distorts” the IEA’s mission.

Wright didn’t, however, just come to Paris to chastise the Europeans. Prompted by a remark from Jean-Luc Palayer, the top U.S. executive of French uranium giant Orano, Wright called the company “fantastic” and praised plans to build new enrichment facilities and bring waste reprocessing to America. While the French, Russians, and Japanese have long recycled spent nuclear waste into fresh fuel, the U.S. briefly but “foolishly” banned commercial reprocessing in the 1970s, Wright said, and never got an industry going again. As a result, all the spent fuel from the past seven decades of nuclear energy production is sitting on site in swimming pools or dry cask storage. “We want to have a nuclear renaissance. We have got to get serious about this stuff. So we will start reprocessing, likely in partnership with Orano,” Wright said. Designating Yucca Mountain as the first U.S. permanent repository for nuclear waste set the project in Nevada up for failure in the early 2000s, Wright added. “In the United States, we’ve tried to find a permanent repository for waste and we’ve had, I think, the wrong approach,” he noted. The Trump administration, he said, was “doing it differently” by inviting states to submit proposals for federally backed campuses to host nuclear enrichment and waste reprocessing facilities. Still, reprocessing leaves behind a small amount of waste that needs to be buried, so, Wright said, “we’re going to develop multiple long-term repositories.”
The Trump administration could tweak tariffs on metals and other materials, U.S. Trade Representative Jamieson Greer said Tuesday. During an appearance on CNBC’s “Squawk Box,” Greer said he’d heard from companies who claimed they needed to hire more workers to navigate the tariffs. “You may want to sometimes adjust the way some of the tariffs are for compliance purposes,” he said. “We’re not trying to have people deal with so much beancounting that they’re not running their company correctly.” Still, he said, the U.S. is “shipping more steel than ever,” and has, as I reported in a newsletter last month, the first new aluminum smelter in the works in half a century. “So clearly those [tariffs] are going in the right direction and they’re going to stay in place.”

California Governor Gavin Newsom, widely seen as a frontrunner for the Democratic presidential nod in two years, is already staking out an alternative energy approach to Trump. During a stop in London on his tour of Europe, Newsom this week signed onto a new pact with British Energy Secretary Ed Miliband, pledging to work together with the United Kingdom on deploying more clean energy technologies such as offshore wind in the nation’s most populous state. One of the biggest winners of the deal, according to Politico, is Octopus Energy, the biggest British energy supplier, which is looking to enter the California market. But the agreement also sets the stage for more joint atmospheric research between California and the U.K. “California is the best place in America to invest in a clean economy because we set clear goals and we deliver,” Newsom said. “Today, we deepened our partnership with the United Kingdom on climate action and welcomed nearly a billion dollars in clean tech investment from Octopus Energy.”
France, meanwhile, is realigning its energy plan for the next nine years in a way the Trump administration will like. The draft version of the plan released last year called for 90 gigawatts of installed solar capacity by 2035. But the latest plan published last week reduced the target to a range of 55 to 80 gigawatts. Onshore wind falls to 35 to 40 gigawatts from 40 to 45 gigawatts. Offshore wind drops to 15 gigawatts from 18 gigawatts. Instead, Renewables Now reported, the country is betting on a nuclear revival.
When Democrats unseated two Republicans on Georgia’s five-member Public Service Commission, the upsets signaled a change to the state’s utility regulator so big one expert described it to Heatmap’s Emily Pontecorvo at the time as “seismic.” Now one of the three remaining Republicans on the body is stepping aside in this year’s election. In a lengthy post on X, Tricia Pridemore said she would end her eight-year tenure on the commission by opting out of reelection. “I have consistently championed common-sense, America First policies that prioritize energy independence, grid reliability, and practical solutions over partisan rhetoric,” wrote Pridemore, who both championed the nuclear expansion at Georgia Power’s Plant Vogtle and pushed for more natural gas generation. “These efforts have laid the foundation for job creation, national security, and opportunity across our state. By emphasizing results over rhetoric, we have positioned Georgia as a leader in affordability, reliability, and forward-thinking energy planning.”
BHP, the world’s most valuable mining company, reported a nearly 30% spike in net profits for the first half of this year thanks to soaring demand for copper. The Australian giant’s chief executive, Mike Henry, said the earnings marked a “milestone” as copper contributed the largest share of its profit for the first time, accounting for 51% of income before interest, tax, depreciation, and amortization. The company also signed a $4.3 billion deal with Canada’s Wheaton Precious Metals to supply silver from its Antamina mine in Peru in a deal the Financial Times called “the largest of its kind for so-called precious metals streaming, where miners make deals to sell gold or silver that is a byproduct of their main business.”
The mining companies the Trump administration is investing in, on the other hand, may have less rosy news for the market. Back in October, I told you that the U.S. was taking a stake in Trilogy Metals after approving its request to build a mining road in a remote corner of Alaska that’s largely untouched by industry. On Tuesday, the company reported a net loss of $42 million. The loss largely stemmed from what Mining.com called “the treatment of the proposed U.S. government’s investment as a derivative financial instrument” under standard American accounting rules. The accounting impact, however, had no effect on the cash the company had on hand and “is expected to resolve once applicable conditions are met.”
“It’s an environmental catastrophe.” That’s how Brett Davis, the head of a nonprofit that advocates for less pollution at Mardi Gras, referred to the waste the carnival generates each year in New Orleans. Data the city’s sanitation department gave The New York Times showed that the weekslong party produced an average of 1,123 tons of waste per year for the last decade. Reusing the plastic beads that became popular in the 1970s when manufacturing moved overseas and made cheap goods widely accessible just amounts to “recirculating toxic plastic junk no one wants,” Davis told the newspaper. Instead, he’s sold more than $1 million in more sustainable alternative items to throw during the parade, including jambalaya mix, native flower start kits, and plant-based glitter.
Batteries can only get so small so fast. But there’s more than one way to get weight out of an electric car.
Batteries are the bugaboo. We know that. Electric cars are, at some level, just giant batteries on wheels, and building those big units cheaply enough is the key to making EVs truly cost-competitive with fossil fuel-burning trucks and cars and SUVs.
But that isn’t the end of the story. As automakers struggle to lower the cost to build their vehicles amid a turbulent time for EVs in America, they’re looking for any way to shave off a little expense. The target of late? Plain old wires.
Last month, when General Motors had to brace its investors for billions in losses related to curtailing its EV efforts and shifting factories back to combustion, it outlined cost-saving measures meant to get things moving in the right direction. While much of the focus was on using battery chemistries like lithium ion phosphate, otherwise known as LFP, that are cheaper to build, CEO Mary Barra noted that the engineers on every one of the company’s EVs were working “to take out costs beyond the battery,” of which cutting wiring will be a part.
They are not alone in this obsession. Coming into a do-or-die year with the arrival of the R2 SUV, Rivian said it had figured out how to cut two miles of wires out of the design, a coup that also cuts 44 pounds from the vehicle’s weight (this is still a 5,000-pound EV, but every bit counts). Ford has become obsessed with figuring out smarter and cheaper ways for its money-hemorrhaging EV division to build cars; the company admitted, after tearing down a Tesla Model 3 to look inside, that its Mustang Mach-E EV had a mile of extra and possibly unnecessary wiring compared to its rival.
A bunch of wires sounds like an awfully mundane concern for cars so sophisticated. But while every foot adds cost and weight, the obsession with stripping out wiring is about something deeper — the broad move to redefine how cars are designed and built.
It so happens that the age of the electric vehicle is also the age of the software-defined car. Although automobiles were born as purely mechanical devices, code has been creeping in for decades, and software is needed to manage the computerized fuel injection systems and on-board diagnostic systems that explain why your Check Engine light is illuminated. Tesla took this idea to extremes when it routed the driver’s entire user interface through a giant central touchscreen. This was the car built like a phone, enabling software updates and new features to be rolled out years after someone bought the car.
As Tesla ruled the EV industry in the 2010s, the smartphone-on-wheels philosophy spread. But it requires a lot of computing infrastructure to run a car on software, which adds complexity and weight. That’s why carmakers have spent so much time in the past couple of years talking about wires. Their challenge (among many) is to simplify an EV’s production without sacrificing any of its capability.
Consider what Rivian is attempting to do with the R2. As InsideEVs explains, electric cars have exploded in their need for electronic control units, the embedded computing brains that control various systems. Some models now need more than 100 to manage all the software-defined components. Rivian managed to sink the number to just seven, and thus shave even more cost off the R2, through a “zonal” scheme where the ECUs control all the systems located in their particular region of the vehicle.
Compared to an older, centralized system that connects all the components via long wires, the savings are remarkable. As Rivian chief executive RJ Scaringe posted on X: “The R2 harness improves massively over the R1 Gen 2 harness. Building on the backbone of our network architecture and zonal ECUs, we focused on ease of install in the plant and overall simplification through integrated design — less wires, less clips and far fewer splices!”
Legacy automakers, meanwhile, are racing to catch up. Even those that have built decent-selling quality EVs to date have not come close to matching the software sophistication of Tesla and Rivian. But they have begun to see the light — not just about fancy iPads in the cockpit, but also about how the software-defined vehicle can help them to run their factories in a simpler and cheaper way.
How those companies approach the software-defined car will define them in the years to come. By 2028, GM hopes to have finished its next-gen software platform that “will unite every major system from propulsion to infotainment and safety on a single, high-speed compute core,” according to Barra. The hope is that this approach not only cuts down on wiring and simplifies manufacturing, but also makes Chevys and Cadillacs more easily updatable and better-equipped for the self-driving future.
In that sense, it’s not about the wires. It’s about all the trends that have come to dominate electric vehicles — affordability, functionality, and autonomy — colliding head-on.
