Europe could teach America a thing or two about interconnection.
As the invasion of Ukraine raged last year, all eyes were on Europe’s power grid. Gas prices skyrocketed, Scandinavia’s water levels fell, and France’s trusty nuclear power plants went offline. It was a test of whether the world’s most interconnected energy grid could keep the lights on under extreme stress — and Europe passed. Today, as increasingly volatile weather patterns wreak havoc on infrastructure, the grid is proving to be more important than ever.
“Climate change is going to make us rely on the grid more,” Michael Pollitt, a professor of economics at Cambridge and an expert in energy economics, told me. “It’s not just gas price effects across Europe, it’s low water years and low wind years that will have impacts everywhere.”
This summer’s extreme heat could have been the next greatest threat to the power grid following the invasion of Ukraine. But instead, the stresses posed by recent weather have shown the strength of Europe’s power grid, proving the importance of interconnection in an era of global warming.
Europe’s power grid is made up of a series of interconnected localized grids. The primary one is the continental grid, where about 15% of the continent’s energy is traded across borders every year. This grid serves 400 million consumers across 24 countries, including most of the European Union countries, plus the Balkans and Turkey. These 24 countries are also connected to several other grids: the Nordic grid, the British grid, the Irish grid, and, as of August this year, the Baltic grid. Those additions bring electricity to more than 600 million consumers. In addition, there are discussions about connecting North Africa’s power grid, and especially Morocco, which would provide a rich source of solar energy.
Each country invests in what they do best: Norway champions hydropower, France has nuclear power plants, the U.K. invests in wind turbines, Spain does solar, etc. And each one can sell the excess energy to the grid to assist other countries. When water levels are low in the summer months, Norway relies on countries like Spain, who have ample power from their solar fields. In the cloudier winter months, Norway returns the favor. There is a call for faster progress on interconnection and transmission to make this into an even more reliable “Super Grid.”
This tool provides an interactive map of the grid today, and the expected changes up until 2040.
This single market allows for an energy security not seen in the United States, which has several disconnected state or regional grids with much more limited interconnection. This not only restricts the distribution of renewable energy in the U.S., but it can lead to blackouts, most famously in Texas in 2021.
One reason that Europe’s grid has proved remarkably resilient is that mutual reliance also means mutually assured destruction.
“If a country were to reduce exports, it would reduce costs in their country,” said Pollitt, referring to fears last year that European countries would unplug from the interconnected grid to safeguard their own energy supplies. “But you barely think about that for too long before you realize it’s a nuclear option to keep prices down.”
EU countries came together to agree on a gas price cap to contain the energy crisis in December 2022. But the rise in gas prices was a powerful incentive for countries to increase their reliance on renewables. Wind and solar generated 10% more energy compared with the same period in 2021-2022, saving the region 12 billion euros in gas imports (about the same in dollars), according to Ember, an energy think tank.
“I’m very happy to see European solidarity manifest itself and be resilient even though there was some temptation to go it alone,” Kristian Ruby, the secretary general for Eurelectric, the association for the electricity sector in Europe, told me. “By standing together and doubling down on solutions, we’ve seen them keep the lights on during an extremely difficult time.”
Extreme weather is the next big hurdle for the grid to overcome. “There’s no doubt that extreme weather events are becoming a strain on electricity operators,” said Ruby. A recent report from Eurelectric says that all power systems are exposed to the effects of extreme weather, including generation, transmission, and distribution. For hydropower, low water levels are detrimental and extreme cold can cause ice and blockages. Geothermal and nuclear energy become less efficient during heat waves because they require water and cold air for cooling. Many of these plants are also vulnerable to coastal and inland flooding.
This summer in particular, the grid was put to the test. Extreme heat in Spain and Italy pushed the grid to its upper limit. Using power from places like Britain, Norway and Switzerland, Spain was able to provide the power needed. It also benefited from investments in solar panels, which supplied 20 percent more solar power than in the summer of 2022.
The grid’s strength is in its variability. “Different types of weather phenomena call for different coping strategies. Resilience is about diversity. It’s about having a mix of different things. One technology will not solve it alone,” said Ruby.
Renewable energy sources differ based on the conditions in which they are built, which can make the electricity supply more adaptable. If there’s enough interconnection to bring power from, say, where it’s sunny or windy to where it’s needed, countries are much less likely to experience blackouts during severe weather. Whereas with fossil fuel based energy like coal plants, the energy supply is concentrated and more susceptible to shocks.
Despite the success, some experts are concerned that transmission isn’t growing fast enough to handle electrification. People are buying more heat pumps and using electric vehicles, but NGO WindEurope says that the grid itself is not expanding at the same pace. Experts also say that as loads increase, electricity flows will become more complex. Ruby advocates more digitalization in order to handle these complex flows.
The EU Commissioner for Energy Kadri Simson wrote an op-ed piece in the Financial Times this month saying that Europe must sustain a fast pace in rolling out renewables and electrifying the economy. She references the need to integrate intermittent renewable power and adapt more decentralized electricity systems. She says the emphasis needs to be on transmission and distribution grids.
The EU reduced the length of time needed for permitting electricity transmission. It also introduced new emergency legislation last year to accelerate the authorization of renewable projects.
Despite concerns about pace, experts seem generally optimistic about the EU's grid. “EU energy and climate policy are really a success story in European coordination and interdependence,” said Pollitt.

Breakthrough Energy is winding down its policy and advocacy office, depriving the Inflation Reduction Act of a powerful defender.
This is part of a Heatmap series on the “green freeze” under Trump.
A major chapter in climate giving has ended.
Breakthrough Energy, the climate philanthropy organization founded by Bill Gates, is closing its policy and advocacy office and has laid off much of its staff in Washington, D.C., Heatmap News has learned.
The layoffs will effectively gut an organization central to the effort to enact the package of clean energy tax cuts passed during the Biden administration. They will also silence one of the few environmental nonprofits that supported nuclear energy, direct air capture, and other new zero-carbon energy innovations.
More than three dozen employees across the United States and Europe are affected by the layoffs, including the office’s senior leadership.
The layoffs, first reported by The New York Times, come amid a wider billionaire pullback from donating to climate causes. The president and CEO of the Bezos Earth Fund departed last month, and the fund has yet to name a permanent replacement. Gates had already significantly diminished his climate giving earlier this year, slashing Breakthrough Energy’s grantmaking budget last month.
Gates’s investments in clean energy companies do not seem affected by the cutback. Breakthrough Energy’s venture capital and investment arm, its fellows program, and its efforts to catalyze new green products remain intact.
“Gates and Breakthrough Energy remain committed to advancing the clean energy innovations needed to address climate change,” a Breakthrough Energy spokesperson told me in a statement. “Our work is focused on accelerating the transition to a cleaner, more prosperous world.”
The closure of Breakthrough’s policy arm — and the presumed end of its grant-making operation — will alter the world of climate nonprofits. Breakthrough Energy was unusual among environmental and energy nonprofits for its enthusiastic support of all forms of zero-carbon energy, including nuclear fission, geothermal power, carbon capture and removal, and nuclear fusion. Many other prominent nonprofits — even some that have shifted to principally fighting against climate change, like the Sierra Club — are more traditional and conservation-minded, and actively oppose the expansion of nuclear power.
“The closure of Breakthrough is indicative of a broader trend that often happens when there’s a change in power in Washington, which is a retreat from federal policy and also often a retreat from the center,” Josh Freed, the senior vice president for climate and energy at Third Way, told me. The Third Way energy team was funded in part by grants from Breakthrough Energy.
“Breakthrough played a critical role in elevating and making clean energy innovation policy very mainstream. That’s going to continue — in part because of … the partners who they brought together, who remain committed to working on this,” Freed added.
The unwinding of Breakthrough Energy’s policy and advocacy arm means that the group will not see the coming battle over the Inflation Reduction Act’s clean tax cuts, which some Republican lawmakers hope to repeal later this year as part of President Trump’s broader package of tax cuts. Gates was seen as instrumental to the lobbying effort to pass the IRA, meeting with Senator Joe Manchin of West Virginia and other lawmakers to support the 2022 legislation.
In an exclusive interview with Heatmap News in 2023, Gates warned that re-electing Donald Trump could derail the Inflation Reduction Act’s effectiveness.
“Right now, companies are responding to the IRA incentives. But you know, if you get Trump elected, and he really gets rid of it, there’s a lot of business plans that will [make people] feel foolish,” he said.
Even if Democrats ultimately enact new provisions similar to the IRA after Trump leaves office, Gates said, the damage of repealing the law would be permanent. “People [will] say, ‘Well, you’re asking me to make a 30-year investment. And half the time, I’m stupid.’”
Just over a year and one election later, Gates reportedly had a more than three-hour dinner with Trump at Mar-a-Lago. He later told Emma Tucker, The Wall Street Journal’s editor in chief, that he was “frankly impressed” by the president-elect.
Tesla already looked beleaguered last week as a tumbling stock price tied to public anger at CEO Elon Musk wiped out more than a half-billion dollars in value. The slide erased all the gains the company had garnered since new Musk ally Donald Trump was reelected as president. On Monday the stock went into full freefall, losing 15% of its value in one day. By Tuesday, Trump had to pose with Tesla vehicles outside the White House to try to defend them.
With a crashing market valuation and rising rage against its figurehead, Tesla’s business is in real jeopardy, something that’s true regardless of Musk’s power in the federal government. If he can’t magically right the ship this time, this self-sabotaging MAGA turn will go down as one of the great self-owns.
Musk’s heel turn has also upended EV culture and meaning. Tesla ownership, once a signal of climate virtue for those who bought in early, has been rebranded as a badge of shame. I’m annoyed that a vehicle I chose for the purpose of not burning fossil fuels has become a political albatross, and that many drivers are resorting to self-flagellating bumper stickers in the hopes it will stop vandals from spray-painting their doors. I wish I knew then what we know now, of course. But what would have become of the EV revolution if we had?
When, exactly, we should have seen Elon’s true self is a question that will inspire countless arguments amid the wave of Tesla hate. Signs were there early. By 2018, before the Model 3 even hit the road, Musk had been hit by so much criticism of his bad tweets and weird behavior that the magazine I worked for at the time felt the need to publish a contrarian defense of him as just the kind of risk-taking innovator the world needs.
That angle aged like milk, but within it lay a few grains of truth. Tesla truly did the bulk of the work in transforming the image of the electric car from a dumpy potato that only climate advocates would ever own, like the original Nissan Leaf, into a desirable consumer product. This is the company’s signature achievement, one that kickstarted the widespread adoption of EVs.
As I’ve written before, Musk wasn’t exactly untainted by 2019, when I bought my own Model 3. The Tony Stark luster of the new space age entrepreneur had worn off as the man sullied himself with pointless “pedo guy” accusations leveled at a rescuer in the Thailand cave incident. But the man had the best electric vehicle on the market, and more importantly, the best charging network. Having just moved to Los Angeles and in need of a vehicle, I wanted an EV to be my family’s only car. Without a home charger in the apartment, I simply couldn’t have lived with a Chevy Bolt or Hyundai Kona EV and the inferior charging networks they relied on at the time.
Millions of people who bought Teslas between then and now made the same choice. Some did it because a Tesla became a status symbol; many others were like me, simply interested in the most practical EV they could get. The ascendance of the Model Y to the world’s best-selling car of any kind in 2023 — a fact that feels astonishing in this flood of horrible vibes and MAGA antagonism just two years later — turned countless people into EV drivers.
After Musk’s far-right reveal, sales are tanking in the U.S., Europe, Australia, and other places that just saw a Tesla boom. Many owners, at least those with the financial wherewithal to buy a new car based on the prevailing political winds, are trying to unload their Musk-affiliated vehicles.
All those people in search of a new ride have a much better selection of electric vehicles to choose from than I did in 2019, which, weirdly, is thanks to the legacy carmakers and new EV startups that raced to catch up to Tesla. If I hadn’t bought a Model 3 in 2019, I would’ve had to get a hybrid and keep burning gasoline. If you want to avoid Musk in 2025, there are great Hyundai, Chevrolet, and other EVs waiting for you.
This isn’t to say there’s no alternate history where electric vehicles take off without Tesla. It didn’t invent the EV. Other automakers were experimenting with EVs before Musk’s company took off and conquered the market, and government environmental goals pushed carmakers toward electrification. Yet it’s hard to argue we’d be where we are now, with tens of millions of EVs on the world’s roads, without the meteoric rise of Musk’s car brand.
It stinks, simply put, to say anything nice about Tesla now, even if one is stating facts. Yes, Musk’s success buoyed electrification on multiple fronts: selling tons of EVs, forcing the other automakers to get serious about their electrification goals, and building a charging network that let his vehicles go just about anywhere a gas car would go. It also made him the world’s richest man, giving him the resources to buy and ruin Twitter and then help Trump get re-elected and undo federal policy support for the very cars he helped popularize. He made the world a better place for a moment, then ruined it because he could.
As an EV advocate, I can’t ignore the fact that Tesla got us to here. But as a human, I eagerly await the time Musk’s company no longer dominates the market it created. Thank goodness, that time seems to be coming soon.
On Lee Zeldin’s announcement, coal’s decline, and Trump’s Tesla promo
Current conditions: Alaska just had its third-warmest winter on record • Spain’s four-year drought is nearing an end • Another atmospheric river is bearing down on the West Coast, triggering evacuation warnings around Los Angeles’ burn scars.
EPA Administrator Lee Zeldin said yesterday he had terminated $20 billion in congressionally-approved climate change and clean energy grants “following a comprehensive review and consistent with multiple ongoing independent federal investigations into programmatic fraud, waste, abuse and conflicts of interest.”
The grants were issued to a handful of nonprofits through the Greenhouse Gas Reduction Fund, a $27 billion program that was the single largest and most flexible program in the Inflation Reduction Act. Zeldin has been targeting the funds since taking office, suggesting they were awarded hastily and without proper oversight. Citibank, where the funds were being held, has frozen the accounts without offering grantees an explanation, prompting lawsuits from three of the nonprofit groups. The EPA’s latest move will no doubt escalate the legal battles. As Politicoexplained, the EPA can cancel the grant contracts if it can point to specific and “legally defined examples of waste, fraud, and abuse by the grantees,” but it hasn’t done that. House Democrats on the Energy and Commerce Committee launched an investigation yesterday into the EPA’s freezing of the funds and Zeldin’s “false and misleading statements” about the GGRF program.
In other EPA news, the agency reportedly plans to eliminate its environmental justice offices, a move that “effectively ends three decades of work at the EPA to try to ease the pollution that burdens poor and minority communities,” as The New York Timesexplained.
President Trump’s 25% tariffs on all steel and aluminum imports came into effect today. As Heatmap’s Emily Pontecorvo has explained, the move could work against Trump’s plans of making America a leader in energy and artificial intelligence. “The reason has to do with a crucial piece of electrical equipment for expanding the grid,” Pontecorvo wrote. “They’re called transformers, and they’re in critically short supply.” Transformers are made using a specific type of steel called grain oriented electrical steel, or GOES. There’s only one domestic producer of GOES — Cleveland Cliffs — and at full capacity it cannot meet even half of the demand from domestic transformer manufacturers. On a consumer level, the tariffs are likely to raise costs on all kinds of things, from cars to construction materials and even canned goods.
The European Union quickly hit back with plans to impose duties on up to $28.3 billion worth of American goods. Trump had threatened to slap an extra 25% duty on Canadian steel and aluminum in retaliation for Ontario’s 25% surcharge on electricity (which was a response to Trump’s tariffs on Canadian goods, including a 10% tariff on Canadian energy resources), but held off after the surcharge was paused and the countries agreed to trade talks.
Wind and solar surpassed coal for power generation in the U.S. in 2024 for the first time, even as electricity demand rose, according to energy think tank Ember. Coal power peaked in 2007 but has since fallen to an all-time low, accounting for 15% of total U.S. electricity generation last year, while combined solar and wind generation rose to 17%.
Gas generation also grew by 3.3% last year, however, now accounting for 43% of the U.S. energy mix and resulting in an overall rise in power-sector emissions. But solar grew by 27%, remaining the nation’s fastest-growing power source and rising to 7% of the mix. Wind saw a more modest 7% rise, but still still accounted for 10% of total U.S. electricity generation.
Ember
“Despite growing emissions, the carbon intensity of electricity continued to decline,” according to the report. “The rise in power demand was much faster than the rise in power sector CO2 emissions, making each unit of electricity likely the cleanest it has ever been.” The report emphasizes that the rise of batteries “will ensure that solar can grow cheaper and faster than gas.”
A group of major companies including tech giants Amazon, Google, and Meta, as well as Occidental Petroleum, have pledged to support a target of tripling global nuclear capacity by 2050 “to help achieve global goals for enhanced energy resiliency and security, and continuous firm clean energy supply.” The pledge, facilitated by the World Nuclear Association, came together on the sidelines of the energy industry’s annual CERAWeek conference in Houston. According to a press release, “this is the first time major businesses beyond the nuclear sector have come together to publicly back an extensive and concerted expansion of nuclear power to meet increasing global energy demand.”
In case you missed it: Toyota plans to roll out an electric truck for the masses by 2026. At least, that’s what can be gleaned from a presentation the company gave last week in Brussels. Details haven’t been released, but Patrick George at InsideEVsspeculates it could be an electric Tacoma, or something more akin to the 2023 EPU Concept truck, but we’ll see. “While Toyota officials stressed that the cars revealed in Belgium last week were for the European market specifically, we all know Europe doesn't love trucks the way Americans love trucks,” George wrote. “And if Toyota is serious about getting into the EV truck game alongside Chevy, Ford, Ram, Rivian and even Tesla, it could be a game-changer.”
President Trump and Elon Musk showed off Tesla vehicles on the White House lawn yesterday, with Trump (who doesn’t drive) pledging to buy one and to label violence against Tesla dealerships as domestic terrorism. Tesla shares rose slightly, but are still down more than 30% for the month.
