Don’t ignore what the president says he wants to do, no matter how unwise it seems.

On Saturday evening, President Donald Trump signed orders placing 25% tariffs on all goods imported from Canada and Mexico, and a lower, 10% tariff on Canadian oil, natural gas, uranium, and other energy sources.
Trump also imposed a 10% tariff on all goods imported from China.
The tariffs will go into effect on Tuesday, giving Trump — who revels in proposing tariffs but has shown some reluctance to impose them for real — another 48 hours to maneuver. But if the new tariffs do actually bite, then they will affect nearly half of America’s imports and reshape some of the world’s most important energy and trading relationships.
Every day, millions of barrels of oil and cubic feet of natural gas flow across the U.S., Canada, and Mexico borders. The three countries have developed an integrated and harmonized network of pipelines, storage tanks, and refineries that has helped turn the United States into the world’s No. 1 producer of oil and natural gas.
The tariffs will almost inevitably disrupt that relationship. They may also upset the millions of dollars’ worth of electricity that shuttles from Canada to the United States every day across their shared power grids.
The tariffs will prove economically painful, although just how damaging is hard to know in advance. They could shrink the United States’ GDP by 0.4%, while increasing taxes by $830 per household, according to an analysis by the Tax Foundation, a center-right think tank. Another estimate from the Budget Lab at Yale says that the tariffs could push up the personal consumption expenditures price index — the Fed’s chosen inflation gauge — by 0.75%, reducing the average household’s purchasing power by $1,200 over the course of a year.

These costs could worsen as Mexico, Canada, and China raise their own tariffs or trade barriers in retaliation. Late on Saturday, Prime Minister Justin Trudeau announced that Canada would impose its own 25% tariffs on CA$155 billion of goods imported from the United States.
The economic hit to the U.S. economy could also be much larger than estimated if some manufacturers respond to higher costs not by hiking prices, but rather by delaying or shutting down production.
We’ve been reporting on the economic impact of these tariffs at Heatmap over the past week, documenting their potential impacts for oil refineries and the electricity grid. But now that the details are here, a few things stand out.
First, the tariffs on China are qualitatively different from the tariffs on our North American neighbors — especially Canada.
Chinese tariffs are not new. Trump engaged China in a trade war during his first term and ultimately reached a handshake agreement, although he has since said that China did not buy enough American agricultural products to keep up its end of the bargain. Some of the tariffs Trump placed on Chinese imports last time — including eye-watering levies on solar panels — remain in effect; the new 10% tariff will be added to those figures.
What did not happen last time was a serious, out-and-out trade war with Canada and Mexico, America’s neighbors and biggest trading partners. Although Trump entertained the possibility of Mexican tariffs during the campaign, he did not propose tariffs on Canadian imports until after his November election.
Second, the tariffs are quantitatively different, too. The president has not yet explained why he has placed higher tariffs on Canada and Mexico, who are our allies, than on China, which is our economic frenemy at best and our geostrategic adversary at worst. During the campaign, Trump sometimes proposed a “universal tariff” of 10% to 20% on all American imported goods, regardless of their country of origin. That proposed universal tariff — which was seen by some analysts as an extreme and unlikely proposal — was at a lower rate than what he is now levying on North American imports.
Third, this trade war has apparently been concocted and planned much more haphazardly than the one during Trump’s first term. Last time, the U.S. was careful to exempt electronics — iPhones, laptops, Xboxes — from its levies, as well as other consumer products. These tariffs do not do so, at least not yet. Nor do they exempt certain minerals that are essential to manufacturing electric vehicle batteries or other high-end electronics. (Bloomberg has reported that as recently as Friday, Tesla was lobbying for an exemption for graphite, a mineral crucial to making EV anodes.)
Finally, what is so striking about these tariffs is how they will be good for almost nobody.
The tariffs will hurt the American oil industry. As I wrote earlier this week, U.S. energy companies have spent tens of billions of dollars on special equipment that can refine the sludgy, sulfurous crude oil extracted in Canada; Canadian companies, in turn, have sold us that crude oil at a discount and built infrastructure so that it can be used by the United States.
The tariffs will hurt oil refineries. The U.S. refines about 18 million barrels of oil a day, but it extracts — even today, around its all-time high — only 13.5 million barrels a day. Most of the difference between what it refines and what it extracts is made up by heavy crude from Canada and Mexico, which blends well with the lighter petroleum produced by U.S. fracking wells. By raising the cost of Canadian and Mexican fuel imports, the cost of all refined products will rise.
The tariffs will hurt anyone who buys gasoline in the Midwest and Mountain West, where Canadian oil plays a much larger role in local markets. They will hurt diesel and jet fuel prices in those regions too.
But the damage will not be limited to the fossil fuel industry.
The tariffs will hurt anyone who uses electricity across the parts of the country, especially the Northeast, that import large amounts of electricity from Canada’s roaring hydroelectric plants.
The tariffs will hurt home builders and construction companies because the United States gets its best building-grade lumber from Canada. That lumber — already made more expensive by a climate change-intensified supply crisis — will now face additional taxes at the border.
The tariffs will hurt anyone who wants to buy or rent a home in the United States because the lack of lumber will worsen the housing shortage and general affordability crisis.
They will hurt automakers, who in the past three decades have constructed sophisticated supply chains spanning North America — a logistical dance that allows a single vehicle’s components and parts to cross the U.S., Canadian, and Mexico borders many times on their way to becoming a final product. They will hurt autoworkers, who depend on that supply chain. They will even hurt car dealerships, who will respond to higher prices by selling less inventory.
If the dollar rises to accommodate the new tariff level, as some White House officials have argued, then the tariffs will hurt all U.S. domestic manufacturers because their products will become more expensive, and therefore less competitive on the global market.
I am not saying, to be clear, that these tariffs are an economic catastrophe. We don’t actually know their economic cost yet — perhaps it will be minimal. But even then, they will still be a stupid waste of money that will help nobody, and which will make the U.S. economy neither more complex nor more secure.
The tariffs are a warning. As recently as last week, Goldman Sachs analysts put the risk of tariffs at only a 20% chance of actually happening. They ignored what Trump had said he would do because it struck them as too implausible, too unwise, too patently harmful. Perhaps in the next two days they will be proven right. But Trump has begun to blather about many unwise and harmful ideas — invading Panama (where Secretary of State Marco Rubio is headed right now), annexing Greenland, making Canada (somehow) the 51st state. Many seem even more implausible than these tariffs, and yet Donald Trump says that he wants to do them, too. How much longer can Republican lawmakers and business leaders pretend that he doesn’t mean what he says? The chance of calamity has only just begun.

Current conditions: For the first time since 1914, the Atlantic hurricane season may pass without any major hurricanes, per an AccuWeather forecast • From Phoenix to Dallas, flood watches are in effect as the remnants of Hurricane Polo stretch inland from the Pacific through the Southwest • Surigae, now upgraded to a “severe” tropical storm, is set to slam into Japan’s Izu Islands, a partially populated archipelago in the same municipality as Tokyo.
The Department of Energy has ordered the release of 40 million barrels of oil from the Strategic Petroleum Reserve as diesel surpasses $6.50 per gallon and Texas proclaims a statewide “disaster” over soaring prices. The move, which Secretary of Energy Chris Wright said would “stabilize the market,” comes as the Trump administration weighs whether to temporarily ban exports of diesel, a radical step that might only slightly lower American prices while sending Europe’s fuel costs skyrocketing, as the chief executive of the continent’s No. 2 oil company cautioned in a Bloomberg interview this week. The oil is expected to be a loan from the stockpile that would, Wright said, ultimately save Americans more than $3 billion. The transaction follows the same approach the Trump administration has taken since agreeing to distribute 172 million barrels from the Strategic Petroleum Reserve back in March, when the war with Iran began. Had the administration instead sold the barrels through an emergency drawdown instead of a trade, as it did previously, and simultaneously structured the deal to allow it to buy back oil at the lower prices the futures market is trading at presently, the Energy Department could have significantly increased its profits. That’s the finding of a policy memo from the think tank Employ America that I told you about a few weeks ago. The profit could, in turn, be used to invest in America’s fuel stockpile, clearing some of the $230 million backlog of physical repairs needed on the infrastructure that stores the crude. “The choice to deliver more barrels is fraught, but with that decision made, the administration missed an opportunity to set up the SPR for long-term success,” Arnab Datta, Employ America’s managing director of policy implementation, told me in a text message last night. “I hope they consider creative options to do so moving forward.”
Meanwhile, oil is actually flowing through the Strait of Hormuz again. “Iran’s regime has lost control of the Strait of Hormuz,” energy investor Alexander Stahel wrote in a lengthy post on X. The U.S. military’s naval escorts and the United Arab Emirates’ commitment to circumventing Iran’s blockade are returning the critical waterway to “normal,” as my colleague Robinson Meyer wrote. Over text message last night, I asked an energy trader if this meant we were winning. “I’d say we’re losing less than we had been,” they said. “If Iran hadn’t gotten the Houthis to attack Saudi Arabia and seize the Red Sea, we’d definitely be.” Big if!
British Prime Minister Andy Burnham emerged triumphant from the Labour Party’s recent political implosions after he established himself as a pragmatic left-wing populist during his time as mayor of Manchester — drawing frequent comparisons to New York City Mayor Zohran Mamdani. Now Burnham is demonstrating what his brand of “business-friend socialism” means in energy. On Tuesday, Downing Street announced the launch of Great British Grid, a new subsidiary of the state-owned Great British Energy, designed to compete with private companies for investments in the power grid. “We have a cost crisis. We all know it,” Burnham said in a speech, according to The Guardian, which broke news of GB Grid. “The price of energy is crippling for businesses, and British bill payers pay some of the highest energy costs in Europe. We have an energy system where prices are dictated in markets miles away, while families and businesses here shoulder the costs. Once again, the British public has lost control.” His answer? Reverse what he called “40 years of neoliberalism.” Over here on this side of the pond, we are waiting to see what’s in the deal the Senate has brokered to ease federal permitting, one of many hurdles to building new transmission lines in America. The text of the agreement is due out later today.
Down in the South Atlantic, things are heating up in the Falkland Islands, even as temperatures outside remain low. The archipelago has never had a native population — as far as anyone can tell, the longest-lasting settled population has been the mostly British herders and fishers who have voted repeatedly to stay under the British crown. That didn’t stop Argentina, which has claimed what it calls Las Malvinas for centuries, from launching an invasion in 1983, in which the British military won a decisive victory. Now that the sleepy Falklands are preparing to drill oil wells in the offshore economic zone surrounding the islands, Buenos Aires is waging what one Falklander described to the Financial Times as “economic warfare.” Instead of Union Jacked Sea Harriers and Argentinian light cruisers doing the combat, this time Argentina is limiting trade, isolating the Falklands. “We’re just a few thousand people trying not to get blown off a rock,” local radio host Ronnie MacLennan Baird told the newspaper. “We just want to get on with our lives.”

Lots of solar developers are promising to compete with nuclear, geothermal, and hydro plants in generating the type of electricity that matches today’s favored buzzwords of “24/7,” “clean,” and “baseload” by pairing panels with batteries. Few companies, for obvious reasons, actually mean generating solar energy all day and night. Virtus Solis Technology, on the other hand, is promising to pioneer a method for delivering solar power generated from panels affixed to satellites in space, capable of angling at every hour to meet the sun’s rays and beaming wireless power back down to Earth. It’s hardly the only developer reaching for solar in space. But the Troy, Michigan-based startup is the first to get someone to agree to buy that electricity. On Wednesday, the company inked its first power purchase agreement to sell electricity from its debut, 100-megawatt solar satellite to the Chicago-based data center developer Brae Systems over the next 20 years. Virtus Solar called it the “first in a series of commercial offtake agreements” expected in the next several months. As part of the deal, Virtus Solar will build a “dedicated terrestrial receiving station to be constructed in Illinois.” The contract includes an option to increase capacity to 250 megawatts within three years of commercial operations. “Securing a direct 20-year supply of firm, clean power from Virtus Solis ensures our GPU infrastructure operates with predictable power costs and zero carbon emissions, completely insulated from terrestrial grid curtailment,” Brae Systems CEO Vishnu Indukuri said in a statement.
Other frontier energy sources have evolved quickly from plans to deals. Commonwealth Fusion Systems, the current frontrunner in America’s fusion startup race, signed its inaugural power purchase agreement with Google last year. Now the spinout from the Massachusetts Institute of Technology is attracting institutional investors, as my colleague Katie Brigham has written, and inching closer to building out its supply chain. On Wednesday morning, the company announced what it called a “landmark supply agreement” with the Japanese industrial giant Fujikura to buy more than 6,200 miles of high-temperature superconducting tape to help build CFS’ doughnut-shaped ARC fusion reactors.

As of now, the European Union is set to start forcing foreign oil and gas companies to monitor and submit data on their methane emissions or face financial penalties. But Brussels is now considering delaying the methane reporting rules by as much as a year as tight fuel supplies send prices ever higher amid the twin energy shocks from the wars in Iran and Ukraine. On Tuesday, Reuters and OilPrice.com reported that EU Energy Commissioner Dan Jorgensen had confirmed that officials are examining whether to postpone the provisions. The statement came days after Jorgensen made a similar remark to Bloomberg.
Meanwhile, Jorgensen’s native Denmark is heeding the former U.S. Energy Secretary Ernie Moniz’s call to invest more in clean fuels. On Tuesday, Hydrogen Insight reported that the country planned to increase its budget for building a network of dedicated hydrogen pipelines by $850 million.
One of the more memorable moments of the 2024 vice presidential debate came when JD Vance lashed his Democratic rival, Minnesota Governor Tim Walz, for failing to prioritize manufacturing of solar panels in the U.S. The Democrat shot back that such factories were open in his very state. Among them was Heliene, a producer of high-performance solar modules designed for boutique rooftop units. On Tuesday, the company rolled out a new all-American module at a moment when solar buyers are increasingly seeking technology that won’t be subject to President Donald Trump’s tariffs. “The new module brings together American-made polysilicon, ingots, wafers, and solar cells, reconnecting critical stages of the solar supply chain with U.S. manufacturing after more than a decade,” the company said, calling the module “an important step in reshoring U.S. solar manufacturing, bringing more of the upstream silicon supply chain back to America.”
As my colleague Emily Pontecorvo and I reported last month, the Department of Commerce just threw solar manufacturers a lifeline by slapping new import levies and restrictions on foreign polysilicon, the main ingredient in solar panels. But the agency halted enforcement until early December, giving importers the opportunity to stockpile in advance of the new rules taking effect. Last week, the Commerce Department moved to ban stockpiling. “Protecting against stockpiling is critical to ensure a functionally viable remedy from the Section 232 rules,” Matt Card, president of the U.S. cell manufacturer Suniva, told PV Tech.
A quick letter of recommendation to close out this morning’s newsletter. Back in 2018, I received a galley copy of a forthcoming book by a niche left-wing sociologist with a growing focus on climate change. The title — After Geoengineering: Climate Tragedy, Repair, and Restoration — struck me. Geoengineering and its associated technological ideas to adapt to a hotter world, such as carbon dioxide removal, were at that point very taboo in climate policy circles. The technology, assuming it even worked, posed what many saw as a moral hazard, a Pandora’s box that, if opened, would sap humanity’s collective will to do the hard work of mitigating fossil fuel emissions. At least, that was the dominant mode of thinking at the time. So, you can imagine, I found that book title provocative. Over the course of 288 pages, the author, Holly Jean Buck, bounced between dense but readable chapters of nonfiction explanations of the latest science behind various cutting-edge climate technologies and sections of fictional sci-fi vignettes. The stories painted a picture of life in the not-so-distant future. One that has stuck with me over the years is a vision of an Oklahoma rancher earning passive income by letting a state carbon disposal program pump captured CO2 into the geological formations beneath his property. I offer my sincere congratulations to Holly, who yesterday was named among the 20 recipients of this year’s MacArthur Foundation’s prestigious “genius grant.”
Novele is aiming to smooth out power consumption for commercial buildings, saving tenants money and easing grid strain.
Electricity is more expensive in times of peak demand — that’s simply a universal truth. But for many commercial building owners and tenants, their most energy-intensive minutes of the month can have an especially outsized impact on their electricity bill. That’s because of the “demand charge,” a fee based on a building’s single highest burst of power consumption, which can make up over 50% of a customer’s monthly bill. Likewise, shrinking those bursts would not only ease strain on the grid, but could also dramatically lower commercial users’ costs.
Or at least that’s Novele’s pitch. The startup, which makes 2-inch-thick, fire-safe lithium-ion batteries that mount on the interior walls of commercial spaces such as offices, hospitals, and big box retailers, announced Wednesday that it raised an oversubscribed $17 million Series A led by impact-focused investor Boisei Labs. The funding will help the company scale its AI-powered battery system, which networks batteries placed throughout a building and uses software to predict impending spikes in power demand. Just before the peak hits, the system can automatically switch the building from grid power to battery power, helping the customer avoid those costly demand charges.
“We learn how the building consumes power, but we’re also taking into account other considerations, like what day of the week it is, how the building is occupied, when it’s being used, what’s happening with the weather conditions,” Novele’s co-founder and CEO Charles Conwell told me.
Of course, battery storage for commercial customers is nothing new. Tesla, for one, has long sold large batteries like its Megapack, along with software designed to help businesses manage and reduce peak demand. But unlike these larger outdoor systems, Novele designed its thin panels for installation inside occupied spaces like hospital hallways and offices, distributing the batteries throughout a building while operating them as a single, coordinated system.
The systems are custom designed, so Novele told me it couldn’t provide an overall cost estimate. But Conwell told me the batteries typically have a 20- to 40-month payback period, the timeframe in which a customer’s electricity bill savings should eclipse the system’s upfront cost. (The company also offers financing options that allow customers to spread out that cost over time.) And while customers may sign up for the cost savings, there are major decarbonization benefits, too. So-called peak-shaving can reduce the need for peaker plants — natural gas facilities that only fire up when demand is highest. These plants are typically among the grid’s most carbon-intensive assets, as they’re designed to ramp up quickly rather than operate efficiently for long periods.
These automated batteries could also enable commercial buildings to participate in virtual power plant programs, which ease strain on the grid by cutting energy use during periods of high demand or by tapping assets like batteries to send power back to the grid. Using stored energy when needed, Conwell explained, is better than typical demand response initiatives, which often require tenants to change their routines — e.g. when they run the dishwasher or charge an EV — to accommodate the grid. That approach, he said, is either “ineffective or doesn’t make the tenants very happy.”
As the company scales, it also envisions building a portfolio of properties that, if they have “a dense enough footprint,” could work in concert to form their own virtual power plant of sorts, Conwell said.
In the near term, however, Novele plans to use its Series A to expand its team, install more systems, and further develop its software. It’s particularly focused on markets where electricity costs are already high or climbing fast, such as California, New York, New England, and parts of the PJM power market. In PJM in particular, record-high capacity prices — largely driven by data center demand — are pushing electricity bills to new heights.
The company says it has already installed batteries for several Fortune 50 customers, though it’s keeping the identities of these early adopters under wraps. Conwell told me that there’s also “a bunch of installations that are in progress,” and that in the coming year, the company will be working toward making the process of purchasing, installing, and operating Novele’s system as seamless as possible.
Once that foundation is in place, Conwell sees an opportunity to help usher in a more responsive, intelligent future for the built environment. “If you get the infrastructure right, if you bring in the controls — the mechanical controls, the machine learning controls, and the artificial intelligence-driven controls — you start to be able to set the stage for a dynamic, autonomous building of the future.”
The former vice president of the United States joined us at Heatmap House for New York Climate Week.
Former Vice President Al Gore needs no introduction. He is, in a way, the original climate influencer. His film An Inconvenient Truth gave rise to a new wave of climate activism in the 2000s. It was one of the highest-grossing documentaries of all time upon its release, and it won an Oscar, a Grammy, and — for Vice President Gore — a Nobel Peace Prize.
He’s remained active in climate policy since then and leads the Climate Reality Project. He is also an investor and was a longtime director at Apple.
For this episode of Shift Key, Vice President Gore joined Rob for a live conversation at our Heatmap House event, part of New York Climate Week. He reflected on the 20th anniversary of An Inconvenient Truth, the existential risk of artificial intelligence, and what has surprised him most about the evolution of climate politics.

Here is an excerpt from their conversation:
Robinson Meyer: Let’s start by talking about 20 years ago, because 20 years ago, An Inconvenient Truth came out. I recently had cause to revisit the film, and I actually have to confess something. I was very excited when the movie came out, but I don’t think I’ve ever admitted this, and maybe this is the wrong audience to do it to: I was too stressed about climate change to actually watch it. Not that it was a daily anxiety, but I was like, “I can’t. There’s so many other things.” And so I actually watched it for the first time only recently.
I had the book, let’s be clear. I had the book.
Al Gore: A limited confession.
Meyer: Yeah, yeah. It was so fascinating watching it 20 years on, because there are some sections of it that I think you could give today. Not that little has changed — the science hasn’t, of course — but the way people think about it, the way people move from denial to doom, hasn’t changed in some ways. I wondered what surprised you most about the intervening 20 years since the film came out. It received a response that, I don’t know what you were anticipating, but it was certainly on a scale beyond what was expected at the time. And then there’s where we are today.
Gore: Well, when Laurie David first made the suggestion, here in this city, I gave an early version of my slideshow when we were promoting that movie. What was it, The Day After —
Meyer: The Day After Tomorrow?
Gore: The Day After Tomorrow. Was that it? Yeah. And they said, “Well, that’s fiction, isn’t it?” And I said, “Well, it’s not as fictional as the then-current administration was about climate.” But when she said, “This needs to be made into a movie,” I said, “You’re crazy.” As one of the early reviewers said, “Al Gore giving a slideshow — what part of that doesn’t scream hit?” So I was a skeptic about the enterprise, and I was surprised at the reception it got.
Really, the credit belongs to the scientists I was just channeling. The fact that everything they predicted has proven to be basically spot on is a credit to them. For the rest of us, the fact that they were so right then should cause us to pay more attention to what they’re warning us about now.
As for what has surprised me, it’s the ferocity and durability and massive continued financing of climate denial by the fossil fuel industry. There was a time during these last 20 years when they said they were going to be part of the solution, and a couple of them made some good-faith efforts in that direction. But then, like Steve Martin on the old SNL, they went, “Nah.” They decided just to give up the ghost and go full speed ahead on more and more fossil fuels. I think they’re losing as we are winning, but they’re hanging in there.
