On wind’s waitlist, pumped hydro, and Taiwanese nuclear
Current conditions: Oman’s Ayn Athum Waterfalls burst to life this week as rain battered the Gulf nation’s southwestern Dhofar governorate • Severe monsoon flooding has deluged parts of the American Southwest, including Navajo Nation, where at least three people have died • Tropical Storm Dujuan is barreling toward Japan, where it threatens flooding and landslides in Tokyo and Chiba.
When the Houthis stormed Yemen’s Red Sea coast last week, the Iran-backed rebels gained new ground from which to attack boats passing through the vital shipping lane, extending Tehran’s reach from the Persian Gulf’s hotly contested Strait of Hormuz to the waterway on the opposite side of the Arabian peninsula. In response, oil prices surged. But the price per barrel of crude is slipping again as the United States has rebuked Saudi Arabia’s requests for help routing the militants, instead seeking a deal that keeps the Bab al-Mandab Strait open to American and Israeli ships. Over the weekend, U.S. diplomats met with Houthi officials in neutral Oman, Reuters reported. Following the talks, the Times of Israel reported that Houthis promised not to attack any Israeli or commercial ships of any kind, only those linked to Saudi Arabia, which has funded the Yemeni government’s campaign against the rebels.
Satellite images published by the investigative site Hunterbrook showed workers building a bypass on Saudi Arabia’s East-West Pipeline, its main conduit for circumventing oil exports around the Strait of Hormuz, to get around the pumping station damaged by a Houthi attack. But the promise of free movement through the Red Sea sent the price of oil down by between 1% and 4% on Thursday.
Just yesterday, I told you that the Trump administration had moved to drastically change how the government interprets the Endangered Species Act to only consider deaths of protected animals illegal if the creatures were intentionally targeted. Such a shift would exclude the vast majority of deaths linked to energy companies, such as when birds land in toxic oil ponds or collide with wind turbines. Whether federal enforcement ultimately reflects that interpretation depends on the outcome of a forthcoming lawsuit. Already, Earthjustice has vowed to file litigation challenging the Trump administration’s legal memo directing federal agencies on its new view of the nation’s bedrock conservation law. “The government’s new legal position is a prescription for extinction. It says that as long as you claim you didn’t mean to kill an endangered species, the law can’t and won’t stop you,” Earthjustice attorney Ben Levitan said in a press release. “That’s ridiculous — and a totally illegal, active misreading of the Endangered Species Act. We’ll see the Trump administration in court about this.”
The toll wind turbines take on migratory birds is a favorite talking point of the energy source’s opponents. But relief from the responsibility to avoid killing birds would be cold comfort to the wind industry as developers wait for the Trump administration to follow a court ruling requiring it to continue processing applications for turbines. As my colleague Jael Holzman wrote yesterday, the administration has continued delaying. At least one other legal fight within the offshore wind industry has, meanwhile, come to a conclusion. Vineyard Wind and its turbine supplier GE Vernova, announced an “amicable settlement” this week that resolves “all outstanding litigation,” the New Bedford Light reported. The developer sued the supplier in April, accusing GE Vernova of an $800 million breach of contract following a blade failure in 2024.

The U.S. needs more long-term energy storage, and few technologies are better tested by time than using excess electricity to pump water into a reservoir, where it can be released downhill and run through turbines to generate huge bursts of power when it’s needed. Back when the U.S. had lots of nuclear power, pumped hydro plants harvested the unused electrons during the night. With solar now producing more electricity during the day in some parts of the country than the grid demands, pumped hydro is seeing a potential renewal. But the U.S. hasn’t built any pumped hydro facilities since the 1990s. A project that looked likely to break that dry spell is now on pause as the Trump administration heeds opponents’ concerns and orders a new study on its environmental impact.
The Federal Energy Regulatory Commission has delayed its decision on whether to license the $3 billion project to add a pumped hydro facility to the Seminoe Reservoir, a lightning bolt-shaped waterway in southern Wyoming. The Bureau of Land Management said it will conduct a supplemental environmental impact statement and open the door to more public comments and input from local officials. “This feels like a small victory,” CiCi Oliver, a fly-fishing shop owner who opposed the project over its potential disruptions to the ecology of the reservoir, told WyoFile this week.

At the start of the Iran War, some interpreters of President Donald Trump’s supposed four-dimensional geopolitical chess moves suggested that shutting down the Strait of Hormuz was an intentional move to show China’s vulnerable underbelly: Beijing’s dependence on oil imports. And yet, China’s vast oil stockpiles and refining capacity, plus its array of alternative energy sources, allowed the country to slash oil purchases by 23% in the first six months of the war compared to the same period last year, according to a New York Times analysis of customs data. “This is a power that nobody thought China had,” said Erica Downs, a senior research scholar at Columbia University’s Center on Global Energy Policy. “Going forward, it’s going to be really interesting to see: What does China do with this newfound power?” The heaviest answer to that question now weighing on Western officials involves China considering the ramifications of a potential invasion of Taiwan to be less worrying than before.
That’s especially true because Taiwan, by contrast, is more vulnerable to losing access to oil and gas imports than ever before. After completing its decades-long mission last year to shut down the nuclear fleet that powered the island’s 20th century transformation into the world’s premiere chipmaker, Taiwan’s ruling Democratic Progressive Party — which advocates for the republic’s continued de facto independence — left the nation dependent on imported liquified natural gas and crude for the vast majority of its energy. Now, according to Nikkei, the government is hastening its efforts to potentially bring at least one nuclear station back online.
Yet another state is considering a moratorium on data centers — one close to the epicenter of the artificial intelligence boom. Maryland, which shares a grid and a border with northern Virginia’s data center megacluster, could see a ban come into effect as early as next year if state legislators pass a bill in the next session. Governor Wes Moore, a Democrat, said he “will absolutely sign” a statewide ban “if it’s coming from local legislators.” Speaking to Punchbowl News, he suggested that any moratorium would come with loopholes for projects that meet high standards. “I believe local jurisdictions should have a say. There are certain local jurisdictions who want it,” he said. “I just need them to understand I have very strict guidelines for what is actually going to get state approval.”
A startup founded by members of the team of U.S. government scientists that first achieved net-energy gain from a fusion reaction has hit a new milestone that should raise the eyebrows of even skeptics of the so-called holy grail of clean power. Less than two months after publicizing its roadmap to commercial fusion, Inertia Enterprises ran a simulation demonstrating that its first commercial plant will be capable of producing 25 times more energy than the laser needed to trigger the reaction, the company told my colleague Katie Brigham in an exclusive.

The company using the only technology proven to achieve breakeven has simulated net energy gain.
Less than two months after publicizing its roadmap to commercial fusion, Inertia Enterprises has checked step one off its list. The startup ran a simulation demonstrating that its first commercial facility will be capable of producing over 25 times more fusion energy than the laser energy put into it, Inertia told Heatmap exclusively.
This is actually the second milestone Inertia has achieved on its 10-point roadmap to building a grid-scale power plant by the mid-2030s — the startup announced last month that it had cut the manufacturing time for its fusion fuel pellets from days to minutes. But for the lay fusion observer, this latest achievement may be the more striking of the two. So far, the only entity to achieve breakeven — the point at which a fusion reaction produces more energy than it consumes — is Lawrence Livermore National Lab’s National Ignition Facility.
Inertia, founded last year by current and former Lawrence Livermore scientists, is now building on that result under a formal research partnership with the lab, using the same technical approach as NIF: firing high-powered lasers at a tiny pellet of fusion fuel, compressing it until the nuclei fuse and release enormous amounts of energy.
The new results, which Inertia said it’s submitting for peer review, demonstrate that the company’s first commercial-scale plant ought to generate over 250 megawatts of electricity for the grid. But because the startup’s machine has yet to be built, the projected energy gain and power output come from a so-called “virtual shot,” a high-fidelity computer simulation that uses the same design codes Lawrence Livermore has used for its own successful ignition experiments, and is thus calibrated and benchmarked against real results.
“We are simulating all the things that we know happen in a fusion experiment, and it’s using the validated models — the best, highest-fidelity physics models that have been validated to NIF ignition experiments — to project where we will be with Inertia,” the startup’s co-founder, Annie Kritcher, told me. The simulation accounts for factors such as “target defects, variations in laser performance, laser delivery, [and] injection tolerances,” she explained.
Even when variables like these fluctuate, Kritcher said, the machine’s energy yield should barely change. That sets Inertia’s system apart from NIF’s, which operates right on the so-called “ignition cliff,” where small imperfections in the fusion fuel target or slight variations in laser performance can determine whether the system achieves ignition at all. But because Inertia designed its system to operate far above that threshold, minor flaws should translate only to modest dips in performance.
Other fusion startups have run simulations demonstrating the validity of their underlying physics and — in industry leader Commonwealth Fusion Systems’ case — even projecting their ability to exceed breakeven. But Kritcher argues that Inertia’s “virtual shot” is a more meaningful achievement because the startup’s plant design replicates the underlying physics validated by NIF, the only fusion experiment yet to cross breakeven in the real world. “The extrapolation risk for the other validation simulations is much, much, much higher,” she told me.
Kritcher has experienced this risk firsthand during her many years running experiments at NIF. When the facility fired its first real shots at ignition in 2011, she was working as a post-doctoral researcher at the national lab, and sincerely believed these early experiments would be a success. But the shots turned out to be “orders of magnitude off” from achieving their goal, thanks to the “unknown unknowns and the physics that weren’t included” in the team’s initial modeling.
Other companies that haven’t yet proven their physics on a real-world machine still face those “unknown unknowns,” she explained, whereas Inertia has been able to unveil and eliminate as many as anyone has yet found. The startup’s plant design is by no means an exact replica of NIF, however. For starters, its fusion targets will be twice as large, and its lasers roughly five times as powerful. The facility will also fire 10 shots per second, compared with NIF’s roughly one shot per week, using thousands of individually adjustable laser beams rather than NIF’s fixed 192. So as is nearly always the case when scaling up, some unknown unknowns likely remain.
But Kritcher is confident that the virtual shot will translate to real world performance — a level of certainty she admittedly hasn’t always had in her decades of nuclear engineering research and practice. In addition to her role at Inertia, Kritcher remains a senior scientist at Lawrence Livermore, where she has led the physics design for NIF’s fusion energy experiments since 2019.
A few years before the lab ultimately achieved breakeven in 2022 — more than a decade after its first attempts — Kritcher was beginning to doubt that they would ever get there. Then, in 2021, NIF reached a breakthrough that went largely unnoticed outside the ranks of dedicated fusion observers: It fired a shot that produced 70% as much fusion energy as the reaction consumed, bringing the facility within striking distance of net energy gain. And while it didn’t reach that threshold, the scientists said the experiment demonstrated ignition — a self-sustaining fusion burn.
The result gave Kritcher assurance that the lab was on the cusp of energy gain. Now, she feels a similar level of confidence that Inertia can translate its simulated 25x energy gain into a real world commercial facility. “The change that we made going from that first ignition result — the 0.7x gain to the [net energy] gain result — that’s the kind of change I feel like we’re making here,” she told me. “It’s working now, and we’re just making it bigger and better.”
Greenhouse gas pollution could drop by half a percent this year, according to a new analysis.

Back in March of last year, I coined the phrase “Degrowth Donald” to describe President Donald Trump’s accidental environmental impact.
Trump might say that climate change was a “hoax” or “scam,” I said. But when you looked at his actions, a different set of beliefs emerged.
He imposed a 10% tax on Canadian oil — a far more effective deterrent on consuming Albertan crude than a decade of protests against Keystone XL. He taxed foreign car imports and levied new tariffs on single-family-home building materials. You could say he had, I don’t know, rhubarb politics — a MAGA red stalk erupting in big green leaves.
Of course, Trump’s actual environmental politics are far more complicated. He has declared war on wind energy and gutted greenhouse gas rules. As you read in Heatmap AM this morning, the Trump administration announced today it would transform the Endangered Species Act to legalize a much broader range of animal killings.
But every so often, Degrowth Donald rides again. And so it is with the Iran war, which has gone on much longer than Trump initially envisioned, changed the global energy economy, and made China’s distinctive approach to energy security — which relies on electrification and large oil and mineral stockpiles — look more popular globally. It has triggered an energy crisis that is, at the moment, getting worse: Even in the United States, gasoline prices are surging again, and diesel is nearing its post-2022 inflation-adjusted record highs, according to Patrick De Haan, the head of petroleum analysis at GasBuddy. Energy prices are even higher in much of Europe.
One upshot of these higher prices, though? Emissions now seem to be going down. According to a new analysis from Carbon Brief, a U.K.-based nonprofit, global emissions from fossil fuels will fall by half a percent this year because of higher oil and natural gas prices caused by the Iran war and Strait of Hormuz closure. What’s interesting is that coal burning will actually increase — by more than 1% — but it will be swamped by declines from oil and gas consumption.
That’s a change from what authorities once expected. Last year, the International Energy Agency projected that global coal use would decline this year because of Chinese policies. But fuel switching will drive it up.
Of course, emissions declines caused by higher prices (or economic downturns) are the worst type of reductions. What we want to see, instead, is countries switching to lower-carbon forms of energy. But energy crises have a way of pushing every country’s energy policy in new directions. This year’s events have convinced Thailand, for instance, to reduce its liquified natural gas consumption and switch to renewables instead; they have caused Canada to open its market up to cheap Chinese electric vehicles and pursue an “associate membership” with the European Union. The 1970s oil crisis ultimately created the global energy regime of the 1980s and 1990s. What else countries might learn from this crisis is not too hard to guess.
The administration told a federal court that it has a “new analytical methodology,” hence the continued delays.
A federal judge ruled in early August that the Trump administration’s freeze on vertical height clearances for wind turbines was likely illegal. More than a month later nearly all of the wind energy projects remain on pause, as federal officials add new red tape that industry representatives say runs afoul of the court’s edict.
Let’s catch-up quickly on the American wind sector’s existential dilemma: the federal government has control over airspace higher than 200 feet from the ground and wind farm turbines essentially always enter that sphere of control. For at least a year and a half, the Trump administration through the Department of Defense and the Federal Aviation Administration has slowly gummed up what industry and former government officials have said was once a rote, benign bureaucratic process for ensuring turbine rotation didn’t interfere with flight patterns or radar at nearby airports.
So, Trump is delaying key approvals even for wind projects on private land, a worst-case scenario for the industry during his presidency. With support from their respective trade groups, many project developers sued and in August won a preliminary injunction against this de-facto national wind energy freeze. The court ruling said federal law laid out clear deadlines for completing these airspace reviews and the administration was willfully missing them.
“[In] light of DoD’s review freeze that started a year ago and still has no end in sight, the wind developers would naturally look to the same deadlines for relief,” U.S. District Judge Karin Immergut wrote, stating the administration’s pause violated the Administrative Procedures Act. Immergut also said the Trump administration potentially violated the law by reviewing projects under a new national security “methodology” that was defined by Congress.
But on Thursday, in its first update to the court since the ruling, the Justice Department laid out how essentially all projects remain at a standstill because they were adopting a new kind of comprehensive review process.
The administration claimed that “as a matter of policy” it had “resumed processing wind energy project applications,” but it only described a single instance where a company had heard from the military about moving forward. In addition, that company as well as all others affected by the freeze would still face a “new analytical methodology” for federal agencies reviewing height clearances for all projects, which appears to fly in the face of the ruling. The Justice Department did not provide any more detail about the methodology in its status update to the court.
Nicole Hughes, executive director of lead plaintiff Renewable Northwest, asserted in an interview Tuesday that the agency isn’t complying with the court order. “It appears to me they’re still stalling,” Hughes told me, adding the federal government’s reluctance to proceed is creating “a pretty high risk” for developers of any new wind projects in the United States. She said if nothing changes in the short term, they’re going to “have to go back to the judge and ask for further clarification as to what it means to comply with this order.”
“The lack of compliance by the administration does put into question the credibility [of the courts] and what pieces hold their feet to the fire? What remedies do we have? There’s never been a time an administration flaunts a judge’s orders the way the administration is.”
The Justice Department status update described a multitude of wind energy projects impacted by the freeze. At least 30 projects apparently already signed deals proposed by the military to mitigate radar impacts and were awaiting a counter-signature from the Department of Defense (which Trump calls the Department of War or DoW). Those previous legal agreements are now at risk of being thrown out, according to the Justice Department filing. The new pathway forward for them apparently is: “DoW will either (i) provide a notice that the project presents an unacceptable risk to national security, (ii) re-engage in negotiations with the developer to attempt to ameliorate any unacceptable risks, or (iii) circulate to the project proponent [a] new model mitigation agreement.”
At least 110 projects were in the middle of discussions with the federal government about mitigating airspace impacts when the injunction came down, according to the DOJ filing, which says none of them have heard from officials since the injunction. “As of this filing, developer re-engagements have yet to begin because such discussions need to be informed by the analytical results. Given the number of projects in this category, DoW has been assessing how to resume review and engagement with the developers.”
The DOJ said another 50 projects awaiting initial meetings with the federal government about airspace risk will begin once the administration “finishes with those” 110 projects that were in the middle of the process. That waiting list will also include another at least 40 projects the Justice Department said received “presumed risk” airspace notices from the federal government.
We’ve seen the Trump administration use extralegal means to delay wind energy before, but never to this extent or after a judge ruled against them. The Interior Department had been freezing wind and solar projects on federal lands under a policy requiring Secretary Doug Burgum sign off on routine approvals, but those typical government processes seem like they’ve resumed after a different federal court ruling enjoining that policy.
American Clean Power, the largest utility-scale solar and wind energy trade group, declined to comment. The Department of Defense did not respond to a request for comment.
