As of Sunday, April 16, Germany is no longer producing any electricity from nuclear power plants.
Closures of the Emsland, Isar II, and Neckarwestheim II nuclear plants in Germany were expected. The country announced plans to phase out nuclear power in 2011. In the fall of 2022, with the Ukraine war constraining access to energy especially in Europe, Germany decided to keep these existing nuclear reactors operating for an additional few months to bolster supplies.
“This was a highly anticipated action. The German government extended the lifetimes of these plants for a few months, but never planned beyond that,” David Victor, a professor of innovation and public policy at UC San Diego, told CNBC.
Responses to the closures ranged from aghast that Germany would shut down a clean source of energy production while global response to anthropogenic climate change continues to be insufficient, to celebratory that the country will avoid any nuclear accidents like those that have happened in other parts of the world.
‘The whole thing is incomprehensible’
A collection of esteemed scientists, including two Nobel laureates and professors from the likes of MIT and Columbia, made a last-minute plea in an open letter published on April 14 on the nuclear advocacy group’s website, RePlaneteers, to keep the reactors operating.
“In view of the threat that climate change poses to life on our planet and the obvious energy crisis in which Germany and Europe find themselves due to the unavailability of Russian natural gas, we call on you to continue operating the last remaining German nuclear power plants,” the letter states.
The Emsland, Isar II and Neckarwestheim II facilities provided more than 10 million German households with electricity, the open letter states. That’s a quarter of the population.
“This is hugely disappointing, when a secure low carbon 24/7 source of energy such as nuclear was available and could have continued operation for another 40 years,” Henry Preston, spokesperson for the World Nuclear Association, told CNBC. “Germany’s nuclear industry has been world class. All three of those reactors shut down at the weekend performed extremely well.”

Despite the shutdown, some segments of nuclear industrial processes will continue to operate. “Germany’s nuclear sector will continue to be first class in the wider nuclear supply chain in areas such as fuel fabrication and decommissioning,” Preston told CNBC.
While the open letter did not succeed in keeping the nuclear reactors open, it does underscore a crucial reason why nuclear power has been part of global energy conversations recently, after a generational lull in the construction of nuclear power plants: climate change.
Generating electricity with nuclear reactors does not create any greenhouse gases. And as global climate change response efforts continue to fall short of emission targets, nuclear energy is getting renewed consideration.
“Obviously many people in the nuclear industry are disappointed that the government that cares a lot about climate change is shutting massive sources of zero-carbon electric power,” Victor told CNBC.
That view was echoed by Hans von Storch, a climate researcher at the Institute for Coastal Research in Geesthacht, Germany, and a signatory of the open letter, told CNBC.
“While a legitimate decision, it is not a wise decision,” Storch told CNBC. “This out-phasing of nuclear, with existing plants, leads to an increase of greenhouse gas emissions in Germany, even though according to another political decision, the fast decarbonization should have priority.”
“For me, as a climate scientist, the whole thing is incomprehensible,” Storch told CNBC.
Anti-nuclear movement supporters gather to celebrate the shuttering of Germany’s last nuclear power plants on April 15, 2023 in Munich, Germany. Emsland, Neckarwestheim 2 and Isar 2 are Germany’s last three operating nuclear power plants and are scheduled to cease operation tonight. Their closure was originally scheduled for December 31 of 2022, though Germany’s government coalition extended their operation due to the turbulent energy market resulting from Russia’s military invasion of Ukraine. The shuttering of the plants marks a historic chapter in German history and is being celebrated by Germany’s decades-old, grassroots anti-nuclear movement.

Fear of accidents and a focus on renewables
The German government says it is making the country safer by closing down the nuclear reactors.
“The nuclear phase-out makes Germany safer and avoids additional high-level radioactive waste. The risks of nuclear power are ultimately unmanageable. No insurance in the world covers the potentially catastrophic extent of damage from a nuclear accident,” a spokesperson for the Federal Ministry for the Environment, Nature Conservation, Nuclear Safety and Consumer Protection in Germany told CNBC.
On June 30, 2011, “the nuclear phase-out law was passed with a broad, nonpartisan majority,” the spokesperson told CNBC.
Volker Quaschning, a professor of renewable energy at the Hochschule für Technik und Wirtschaft Berlin, supports Germany closing its nuclear reactors because of the risk of an accident.
“Nuclear energy is a risky technology. During the Chernobyl reactor accident, Germany was hit by radioactive fallout. A reactor accident in Germany would make large parts of the country uninhabitable. In the course of global uncertainties, the risks for nuclear energy are also increasing,” Quaschning told CNBC.
Also, radioactive waste management is “still unsolved in Germany,” Quaschning told CNBC. “No one in Germany wants a repository for highly radioactive waste near them.”
Instead, the European country says it is focused on building out its wind and solar energy production. By 2030, Germany aims to generate 80 percent of its electricity from renewable energy sources like wind and solar. “We are now putting the policies in place for this and adapting the necessary legislation,” the German government spokesperson told CNBC.
Turning off the nuclear reactors opens the doors for renewables to be the future of energy, Niklas Höhne, a professor the mitigation of greenhouse gases at Wageningen University in the Netherlands, told CNBC.
“In the German context, the phase-out of nuclear energy is good for the climate in the long term. It provides investment certainty for renewable energy; renewables will be much faster, cheaper and safer than expansion of nuclear energy,” Höhne told CNBC.
Nuclear energy is also often more expensive than wind and solar power, Quaschning said, adding, “there are no longer any real advantages with nuclear energy.”
“Nuclear power plants are a hindrance to the energy transition. They are not able to run in stop-and-go mode and cannot really compensate for power fluctuations that arise when using solar and wind energy. With Germany looking to expand solar and wind power very rapidly over the next few years, now is a good time to shut down nuclear reactors to make way for renewable energy,” he said.

Sweeping tariffs on imported aluminum imposed by U.S. President Donald Trump are succeeding in reshaping global trade flows and inflating costs for American consumers, but are falling short of their primary goal: to revive domestic aluminum production.
Instead, rising costs, particularly skyrocketing electricity prices in the U.S. relative to global competitors, are leading to smelter closures rather than restarts.
The impact of aluminum tariffs at 25% is starkly visible in the physical aluminum market. While benchmark aluminum prices on the London Metal Exchange provide a global reference, the actual cost of acquiring the metal involves regional delivery premiums.
This premium now largely reflects the tariff cost itself.
In stark contrast, European premiums were noted by JPMorgan analysts as being over 30% lower year-to-date, creating a significant divergence driven directly by U.S. trade policy.
This cost will ultimately be borne by downstream users, according to Trond Olaf Christophersen, the chief financial officer of Norway-based Hydro, one of the world’s largest aluminum producers. The company was formerly known as Norsk Hydro.
“It’s very likely that this will end up as higher prices for U.S. consumers,” Christophersen told CNBC, noting the tariff cost is a “pass-through.” Shares of Hydro have collapsed by around 17% since tariffs were imposed.
The downstream impact of the tariffs is already being felt by Thule Group, a Hydro customer that makes cargo boxes fitted atop cars. The company said it’ll raise prices by about 10% even though it manufactures the majority of the goods sold in the U.S locally, as prices of raw materials, such as steel and aluminum, have shot up.
But while tariffs are effectively leading to prices rise in the U.S., they haven’t spurred a revival in domestic smelting, the energy-intensive process of producing primary aluminum.
The primary barrier remains the lack of access to competitively priced, long-term power, according to the industry.
“Energy costs are a significant factor in the overall production cost of a smelter,” said Ami Shivkar, principal analyst of aluminum markets at analytics firm Wood Mackenzie. “High energy costs plague the US aluminium industry, forcing cutbacks and closures.”
“Canadian, Norwegian, and Middle Eastern aluminium smelters typically secure long-term energy contracts or operate captive power generation facilities. US smelter capacity, however, largely relies on short-term power contracts, placing it at a disadvantage,” Shivkar added, noting that energy costs for U.S. aluminum smelters were about $550 per tonne compared to $290 per tonne for Canadian smelters.
Recent events involving major U.S. producers underscore this power vulnerability.
In March 2023, Alcoa Corp announced the permanent closure of its 279,000 metric ton Intalco smelter, which had been idle since 2020. Alcoa said that the facility “cannot be competitive for the long-term,” partly because it “lacks access to competitively priced power.”
Similarly, in June 2022, Century Aluminum, the largest U.S. primary aluminum producer, was forced to temporarily idle its massive Hawesville, Kentucky smelter – North America’s largest producer of military-grade aluminum – citing a “direct result of skyrocketing energy costs.”
Century stated the power cost required to run the facility had “more than tripled the historical average in a very short period,” necessitating a curtailment expected to last nine to twelve months until prices normalized.
The industry has also not had a respite as demand for electricity from non-industrial sources has risen in recent years.
Hydro’s Christophersen pointed to the artificial intelligence boom and the proliferation of data centers as new competitors for power. He suggested that new energy production capacity in the U.S., from nuclear, wind or solar, is being rapidly consumed by the tech sector.
“The tech sector, they have a much higher ability to pay than the aluminium industry,” he said, noting the high double-digit margins of the tech sector compared to the often low single-digit margins at aluminum producers. Hydro reported an 8.3% profit margin in the first quarter of 2025, an increase from the 3.5% it reported for the previous quarter, according to Factset data.
“Our view, and for us to build a smelter [in the U.S.], we would need cheap power. We don’t see the possibility in the current market to get that,” the CFO added. “The lack of competitive power is the reason why we don’t think that would be interesting for us.”
While failing to ignite domestic primary production, the tariffs are undeniably causing what Christophersen termed a “reshuffling of trade flows.”
When U.S. market access becomes more costly or restricted, metal flows to other destinations.
Christophersen described a brief period when exceptionally high U.S. tariffs on Canadian aluminum — 25% additional tariffs on top of the aluminum-specific tariffs — made exporting to Europe temporarily more attractive for Canadian producers. Consequently, more European metals would have made their way into the U.S. market to make up for the demand gap vacated by Canadian aluminum.
The price impact has even extended to domestic scrap metal prices, which have adjusted upwards in line with the tariff-inflated Midwest premium.
Hydro, also the world’s largest aluminum extruder, utilizes both domestic scrap and imported Canadian primary metal in its U.S. operations. The company makes products such as window frames and facades in the country through extrusion, which is the process of pushing aluminum through a die to create a specific shape.
“We are buying U.S. scrap [aluminium]. A local raw material. But still, the scrap prices now include, indirectly, the tariff cost,” Christophersen explained. “We pay the tariff cost in reality, because the scrap price adjusts to the Midwest premium.”
“We are paying the tariff cost, but we quickly pass it on, so it’s exactly the same [for us],” he added.
RBC Capital Markets analysts confirmed this pass-through mechanism for Hydro’s extrusions business, saying “typically higher LME prices and premiums will be passed onto the customer.”
This pass-through has occurred amid broader market headwinds, particularly downstream among Hydro’s customers.
RBC highlighted the “weak spot remains the extrusion divisions” in Hydro’s recent results and noted a guidance downgrade, reflecting sluggish demand in sectors like building and construction.

Danish energy giant Ørsted has canceled plans for the Hornsea 4 offshore wind farm, dealing a major blow to the UK’s renewable energy ambitions.
Hornsea 4, at a massive 2.4 gigawatts (GW), would have become one of the largest offshore wind farms in the world, generating enough clean electricity to power over 1 million UK homes. But Ørsted announced that it’s abandoning the project “in its current form.”
“The adverse macroeconomic developments, continued supply chain challenges, and increased execution, market, and operational risks have eroded the value creation,” said Rasmus Errboe, group president and CEO of Ørsted.
Reuters reported that Ørsted’s cancellation of Hornsea 4 would result in a projected loss of up to 5.5 billion Danish crowns ($837.85 million) in breakaway fees and asset write-downs. The company’s market value has declined by 80% since its peak in 2021.
The cancellation highlights significant challenges currently facing offshore wind development in Europe, particularly in the UK. The combination of higher material costs, inflation, and global financial instability has made large-scale renewable projects increasingly difficult to finance and complete.
Ørsted’s decision is a significant setback to the UK’s energy transition goals. The UK currently has around 15 GW of offshore wind, and Hornsea 4’s size would have provided almost 7% of the additional capacity needed for the UK’s 50 GW by 2030 target, according to The Times. Losing this immense project off the Yorkshire coast could hamper the UK’s pace of reducing dependency on fossil fuels, especially amid volatile global energy markets.
The UK government reiterated its commitment to renewable energy, promising to work closely with industry leaders to overcome financial and logistical hurdles. Energy Secretary Ed Miliband told reporters in Norway that the UK is “still committed to working with Orsted to seek to make Hornsea 4 happen by 2030.”
Ørsted says it remains committed to its other UK-based projects, including the Hornsea 3 wind farm, which is expected to generate around 2.9 GW once completed at the end of 2027. Despite the challenges, the company emphasized its ongoing commitment to the British renewable market, pointing to the critical need for policy support and economic stability to ensure future developments.
Yet, the cancellation of Hornsea 4 demonstrates that even flagship renewable projects are vulnerable in the face of economic pressures and global uncertainties, which have been heightened under the Trump administration in the US.

The Tesla Roadster appears to be quietly disappearing after years of delay. is it ever going to be made?
I may have jinxed it with Betteridge’s Law of Headlines, which suggests any headline ending in a question mark can be answered with “no.”
The prototype for the next-generation Tesla Roadster was first unveiled in 2017, and it was supposed to come into production in 2020, but it has been delayed every year since then.
It was supposed to get 620 miles (1,000 km) of range and accelerate from 0 to 60 mph in 1.9 seconds.
It has become a sort of running joke, and there are doubts that it will ever come to market despite Tesla’s promise of dozens of free new Roadsters to Tesla owners who participated in its referral program years ago.
Tesla uses the promise of free Roadsters to help generate billions of dollars worth of sales, which Tesla owners delivered, but the automaker never delivered on its part of the agreement.
Furthermore, many people placed deposits ranging from $50,000 to $250,000 to reserve the vehicle, which was supposed to hit the market 5 years ago.
The official timelines from Tesla are pretty useless at this point since they haven’t stuck to any of them, but the latest official one dates back to July 2024 when CEO Elon Musk said this:
“With respect to Roadster, we’ve completed most of the engineering. And I think there’s still some upgrades we want to make to it, but we expect to be in production with Roadster next year. It will be something special.”
He said that Tesla had completed “most of the engineering”, but he initially said the engineering would be done in 2021 and that was already 3 years after the prototype was unveiled and a year after it was supposed to be in production:
Musk commented on the Roadster again in October 2024, but he didn’t reiterate the 2025 timeline. Instead, he called the new Roadster “the cherry on the icing on the cake.”
Tesla’s leadership has been virtually silent about the new Roadster since. Two Tesla executives even had to be reminded about the Roadster by Jay Leno after they “forgot” about it when listing upcoming new Tesla vehicles with tri-motor powertrain.
There was one small update about the Roadster in Tesla’s financial results last month.
The automaker has a table of all its vehicle production, and the Roadster was updated from “in development” to “design development” in the table:
It’s not clear if that’s progress or Tesla is just rephrasing it. Either way, it is not “construction”, which makes it unlikely that the Roadster is going into production this year.
If ever…
Electrek’s Take
It looks like Tesla owes about 80 Tesla Roadsters for free to Tesla owners who referred purchases, and it owes significant discounts on hundreds of units.
It’s hard for me to believe that Tesla is not delivering the new Roadster because the vehicle program would start about $100 million in the red, but at this point, I have no idea. It very well might be the reason.
However, I think it’s more likely that Tesla is just terrible at bringing multiple vehicle programs to market simultaneously. Case in point: it launched a single new vehicle in the last five years.
At this point, I think it’s more likely that the Roadster will never happen. It will join other Tesla products like the Cybertruck Range Extender.
