Why Patagonia, REI, and just about every other gear retailer are going PFAS-free.
Giving up on hourly matching by 2030 doesn’t mean giving up on climate ambition — necessarily.
Current conditions: The East Coast’s Acela corridor is cooling down this week, with temperatures dropping from 85 degrees Fahrenheit in Philadelphia yesterday to the 60s for the rest of the week • Cape Agulhas is under one of South Africa’s Orange Level 6 warnings for damaging winds and dangerous waves • Floods and landslides in Brazil’s northern state of Pernambuco have left six dead and thousands displaced.
The Securities and Exchange Commission has advanced a measure to formally end Biden-era climate disclosure rules for publicly-traded companies. The regulator sent the proposal to the White House’s Office of Management and Budget for review on May 4, according to a post on a government website first spotted by Bloomberg. The Wall Street watchdog’s 2024 disclosure rule mandated that publicly traded companies report on the material risks climate change poses to their business models, including the financial impact of extreme weather. Some large companies would have been required to disclose Scope 1 emissions, which are produced by the firm’s own operations, and Scope 2 emissions, which are produced by companies with which the firm does off-site business such as electricity. The rule had already been watered down before its finalization to remove Scope 3 emissions, which come from suppliers up and down the value chain and from customers who use a product such as oil.
In an even bigger move, the SEC also proposed scrapping mandatory quarterly reporting for U.S.-listed companies, instead switching to a twice-yearly filing. The idea, which President Donald Trump first floated years ago as a way of getting companies to focus on longer-term goals, “would provide companies with increased regulatory flexibility,” SEC chair Paul Atkins told the Financial Times. “Public companies have an obligation under the federal securities laws to provide information that is material to investors. Yet, the rigidity of the SEC’s rules has prevented companies and their investors from determining for themselves the interim reporting frequency that best serves their business needs and investors.” While cast as part of a larger deregulatory push, the move could actually be a boon to climate action. Supporters of decarbonization have long lamented how quarterly reporting norms disincentivized costly bets that take longer than three months to pan out.
If you have ever body surfed in the ocean — or observed how docks and peers weather over time — it’s easy to intuit why harnessing renewable energy from waves is so tricky. Among experts who often list wave energy along with tidal power as two sources of underdeveloped but potentially promising renewable energy, the latter has long been considered the more commercially viable, with turbines harnessing tidal flows already in operation in France and elsewhere. Wave energy, by contrast, has been perceived as a riskier frontier in the energy industry.
That didn’t stop wave-energy startup Panthalassa from raising $140 million in a Series B round led by Silicon Valley billionaire Peter Thiel this week as the company looks to develop floating data centers that can operate in open ocean. The financing will fund the completion of the company’s pilot manufacturing facility near Portland, Oregon, and speed up deployment of its Ocean-3 series of facilities that “will perform AI inference computing at sea” with power generated from ocean waves.
“There are three sources of energy on the planet with tens of terawatts of new capacity potential: solar, nuclear, and the open ocean,” Panthalassa CEO and co-founder Garth Sheldon-Coulson said in a statement. “We’ve built a technology platform that operates in the planet’s most energy-dense wave regions, far from shore, and turns that resource into reliable clean power. We’re now ready to build factories, deploy fleets, and provide a sustainable new source of energy for humanity.” The deal, per the Financial Times, values the company at about $1 billion. “The future demands more compute than we can imagine,” Thiel said in a press release. “Extra-terrestrial solutions are no longer science fiction. Panthalassa has opened the ocean frontier.”
The company has some competition. Earlier this year, the San Francisco-based Aikido Technologies launched a new line of floating platforms for deep-water offshore wind turbines that include data centers built into the ballasts.
Allow me to give you a glimpse into the anxious mind of a young father: Sometimes, I distract myself from my fear over what global weather patterns might look like by the time my one-year-old daughter is my age with my more urgent terror over what particulate matter is entering her perfect little lungs and what microplastics sneak into even her home-cooked meals. Well, worry not! Turns out the two aren’t mutually exclusive. In theory, I knew this was always the case, since the rise of plastic pollution is at least somewhat spurred on by oil and gas companies making big money off the feedstocks for the cheap, single-use plastics that break down into dangerous tiny particles in our environment. But new research shows that microplastics in the atmosphere are actually magnifying the effects of climate change. In a new paper published in the journal Nature Climate Change, scientists in China and the U.S. outlined how tiny, colored plastic bits absorb sunlight as the wind blows them around the world, trapping heat and adding to temperature rise. “The plastic problem is not just in our blue oceans, it is also in the invisible skies above us,” Hongbo Fu, a co-author of the study and an atmospheric scientist at Fudan University in Shanghai, said at a press conference, per Bloomberg. “Climate models need to be updated.”

Like wave and tidal power, geothermal was once a sleepy corner of the clean energy world. But next-generation startups that promised to use new drilling techniques to harness geothermal energy in more places than ever thought possible are radically upending an industry that saw its largest power station — the Geysers in California — built in the 1960s and hitherto hadn’t aimed higher. Until a few years ago, next-generation geothermal drilling was esoteric even among energy nerds. But things change quickly in the modern energy business. Fervo Energy, the first major next-generation startup to prove that fracking technology could be used to revolutionize geothermal power, is now eyeing a $6.5 billion valuation. That’s according to a document the company filed with the SEC this week as it prepares to raise more than $1.3 billion in an initial public offering of its stock.
Fervo sees a big market. As Heatmap’s Matthew Zeitlin wrote last month when the company first filed to go public, Fervo told investors its reviewed leases represent over 40 gigawatts of energy. That’s equal to about 15% of all installed solar capacity in the U.S.

The United Arab Emirates already ranks as the world’s seventh-largest producer of crude, and could ascend as the country’s exit from the Organization of the Petroleum Exporting Countries frees Abu Dhabi to pump for oil. The UAE’s debut atomic power plant — the four-reactor, Korean-built Barakah station in Abu Dhabi — set a new standard for nuclear construction in a Western-aligned nation and vaulted the federation of monarchies to the forefront of global discussions about fission. Now the UAE is making a big move on solar. Abu Dhabi’s state-owned renewables developer Masdar has signed a deal with Emirates Water and Electricity Company to deploy more than 30 gigawatts of solar capacity and 8 gigawatts of batteries. “As the driving force behind the UAE’s energy transition, EWEC is at the forefront of a global shift towards sustainable, utility-scale power and water production,” Ahmed Ali Alshamsi, the utility chief in charge of the Emirates Water and Electricity Company, told PV Tech. “This CFA with Masdar is a pivotal strategic tool that empowers us to accelerate this transformation and meet 60% of Abu Dhabi’s total energy demand from renewable and clean sources by 2035.”
Norway led the world in electric vehicle adoption. It’s now at the forefront of autonomous vehicle adoption. Europe’s first self-driving bus without a supervisor onboard is set to be rolled out in the southwestern city of Stavanger following a recent regulatory change. While the bus still requires preparation by a human before operating, the project has been underway since 2022 and represents Europe’s most advanced public deployment of the technology.
On thorium, South Carolina nuclear, and green steel
Current conditions: Severe thunderstorms are drenching the American South from New Orleans to Virginia Beach • Mount Mayon has forced thousands to evacuate within the Philippines’ Bicol peninsula • Temperatures in Denver are poised to plunge from about 75 degrees Fahrenheit yesterday to 39 degrees today with a chance of snow.

The North American Electric Reliability Corporation, the quasi-governmental watchdog that monitors the health of the power grids that span the United States and Canada, has issued a rare Level 3 warning. The alert, announced Monday, marks only the third time NERC has put out a notice with that degree of severity in its 58-year history. The warning comes on the heels of reports that data centers abruptly went offline in Virginia and Texas, prompting concerns of potential blackouts. “Computational loads, such as data centers, could increase exponentially in the next four years,” NERC said in a draft of the alert, adding that “significant risks” to the power network “need to be addressed through immediate industry action.” Lee Shaver, a senior energy analyst at the Union of Concerned Scientists, told E&E News that NERC’s action was a “big deal.”
The California Energy Commission has issued an administrative investigative subpoena to Golden State Wind seeking documents and information related to the company’s recent deal with the U.S. Department of the Interior to take a payout in exchange for abandoning its offshore wind lease. Last week, the developer announced a deal to scrap its lease in the Morro Bay Wind Energy off the central California coast for $120 million as part of the Trump administration’s efforts to kill off an industry he failed to destroy through regulatory fiat alone. The facility was supposed to be California’s first offshore wind farm, and planned to use floating turbines to account for the steep continental shelf dropoff on the nation’s Pacific Coast. Now the administration’s latest “shady deal” is drawing scrutiny from state regulators. “The Trump Administration is recklessly spending billions of taxpayer dollars on backroom deals that would turn back the clock on innovation,” David Hochschild, the chairman of the California Energy Commission, said in a statement. “Californians deserve immediate answers about the nature of this payout. Taxpayer dollars should be used to build a sustainable energy future, not to pay to make projects disappear.”
Meanwhile, California’s grid operator has switched on a new regional electricity market as part of what E&E News called “a major milestone in the yearslong push to expand energy trading” across the American West. The California Independent System Operator launched its new Extended Day-Ahead Market early Friday morning, allowing California’s investor-owned utilities and the Northwestern giant PacifiCorp, whose coverage area spans two million customers across six states, to trade electricity on the regional market for the first time. “The West is rich with a diverse mix of renewable resources, and this market will capture their potential,” Michael Colvin, director of the California energy program at the Environmental Defense Fund, said in a statement. “Through better sharing of cheap, clean energy beyond state borders, the market will cut household bills, reduce reliance on expensive, polluting fossil plants and build a grid that's bigger than any single extreme weather event.”
For nearly as long as there have been nuclear power plants, there have been thorium bulls insisting the metal is a better fuel than uranium. In most places, the thorium dream faded long ago as ample new sources of uranium were discovered. But China revived the thorium race in 2023, when its experimental molten salt reactor powered by the metal split atoms for the first time. Now the only serious contender in the entire West looking to commercialize thorium is a Chicago-based company taking an unusual approach. Rather than creating a whole new kind of reactor to run on thorium, Clean Core Thorium Energy has designed fuel assemblies that blend thorium with a special kind of uranium fuel and work in existing reactors without any modifications. Clean Core’s technology only works, at least for now, in pressurized heavy water reactors, which make up the bulk of the fleets in Canada and India, though the U.S. has none in operation. But the key verb there is that: It works. On Tuesday, I can exclusively report for this newsletter, Clean Core plans to announce that its patented fuel completed a high burnup irradiation test at Idaho National Laboratory’s Advanced Test Reactor. The fuel burnup represented “more than eight times the typical” output from the traditional uranium fuel used in pressurized heavy water reactors. The latest test “provides meaningful performance data” and demonstrates that Clean Core’s fuel “achieve burnup levels comparable to those seen in PWR fuels while offering improved fuel utilization, enhanced safety characteristics, inherent proliferation resistance, and meaningful reductions in long-lived nuclear spent fuel radioisotopes,” Mehul Shah, Clean Core’s chief executive, told me in a statement. “Our objective has been to introduce thorium into the nuclear fuel cycle in a practical way using existing reactors, and this milestone represents a significant step toward that goal.”
It’s the latest good news for Clean Core. Last month, as I reported for Heatmap, the company inked a deal with the Canadian National Laboratories to manufacture its first commercial fuel assemblies.

In July 2017, South Carolina abandoned its $9 billion expansion of the V.C. Summer Nuclear Station, leaving ratepayers holding the bag and utility executives facing prison time for lying about the project’s viability. Now the pair of Westinghouse AP1000s planned at the site are making a comeback. On Monday, Westinghouse-owner Brookfield Asset Management formed a new joint venture with The Nuclear Company, a reactor construction manager, to work together on building more Westinghouse reactors such as the AP1000 or the smaller version, the AP300. V.C. Summer is the likely first project. “Our team was built on the field of Vogtle and on some of the most complex energy projects in the world,” Joe Klecha, The Nuclear Company’s chief nuclear officer, said in a statement. “We know what it takes to deliver nuclear. What’s been missing is a model that brings together the people, the capabilities, and the capital to do it at speed and scale. That’s what this partnership creates.” The announcement comes as the Trump administration meets with utility executives to discuss funding deals to build the 10 new large-scale reactors President Donald Trump ordered the Department of Energy to facilitate construction on by 2029, as Heatmap’s Robinson Meyer reported. Completing 10 AP1000s would give the U.S. economy a trillion-dollar boost, per a PricewaterhouseCoopers report Westinghouse released in March.
That’s not the only nuclear developer making deals. On Tuesday morning, Blue Energy, another startup focused on serving as a project developer for existing reactor designs, announced a partnership with GE Vernova to work on building the world’s first gas-plus-nuclear plant in Texas. The 2.5-gigawatt project would include GE Vernova’s gas turbines and its BWRX-300 small modular reactors through its joint venture with Hitachi. “Innovative projects like this one will help advance the future of nuclear power and meet the surging demand for electricity,” Scott Strazik, GE Vernova’s chief executive, said in a statement.
Steel, if you’re unfamiliar, is made in two big steps. Traditionally, iron ore is melted down in a coal-fired blast furnace, then forged into steel in a basic oxygen furnace. New plants typically run on something called direct reduced iron, which uses natural gas to turn the ore into iron, then made into steel in an electric arc furnace. The latter process is far cleaner. It can even be green, if the natural gas is swapped for green hydrogen and the electric arc furnace is powered by renewables or nuclear reactors. Nearly 40% of all global clean steel investments to date are hydrogen-powered DRI facilities. That’s according to new data from the Rhodium Group, which released its latest estimates Tuesday. Another 57% of investments are gas-powered DRI plants. While Europe has so far dominated investment into hydrogen DRI, “the region will likely see relatively little demand growth for iron over the coming decades,” the report found. In the fastest growing regions, such as India, Africa, and South America, “most new demand is being met with traditional, fossil-based ironmaking technologies, which risks locking in emissions for decades.” The consultancy’s modeling shows that clean steel supply capacity is on track to exceed demand by between 1.8 and 4.3 times by 2030, “risking a collapse of the nascent industry, where existing projects cannot find buyers and scale production to drive down costs.”
It may be time for a new New Orleans. The city has reached a “point of no return” that will see it surrounded by ocean within decades as climate change worsens. That’s the conclusion of a new paper in the journal Nature Sustainability. “In paleo-climate terms, New Orleans is gone; the question is how long it has,” Jesse Keenan, an expert in climate adaptation at Tulane University and one of the paper’s five co-authors, told The Guardian.
