China's clean-energy investments are paying green dividends. Ember
China’s clean energy boom is bringing a global decline in fossil fuel demand into sight amid declines in usage in the buildings, vehicles, and industries of the world’s second-largest economy, according to the think tank Ember’s latest China Energy Transition Review. The report, released Tuesday morning, found that exports of solar panels, batteries, electric vehicles, and heat pumps are soaring, particularly to emerging economies, making the possibility of developing nations making possible an “energy leapfrog” over the coal phase of growth. From 2015 to 2023, China’s end consumption of fossil fuels fell 1.7% across buildings, industry and transport, while electricity use as a replacement rose by 65%. In power generation, fossil output dropped 2% in the first half of 2025 compared to the same period last year, as wind and solar generation soared by 16% and 43%, respectively. Last year alone, Beijing invested $625 billion in clean energy, 31% of the global total.
“China is now the main engine of the global clean energy transition,” Muyi Yang, coordinating lead author of Ember’s 2025 analysis, said in a statement. “Policy and investment decisions made in China over the last two decades are fundamentally changing the basis of China’s own energy system, and enabling other countries to also move swiftly from fossil to clean.”
As Americans scramble to buy electric vehicles ahead of the expiration of the $7,500 consumer tax credit at the end of this month, fewer of those cars are Teslas. The preliminary August data Cox Automotive released on Monday showed the best month for EVs in U.S. history was the worst for Tesla ever recorded. EVs climbed to almost 10% of total car sales last month, but Tesla’s share fell to 38%, with 55,000 cars sold all month. That’s up just 3% compared to July and down 6% from the year prior, while the company’s total market share fell from just over 40% in July and 45% in the first half of the year. By contrast, Heatmap’s Matthew Zeitlin noted, Tesla commanded about 80% of U.S. EV sales in 2020.
Also on Tuesday, the company unveiled two new energy storage products that could boost its utility division. At the RE+ conference in Las Vegas, Tesla presented the Megapack 3, the latest generation of its utility-scale battery system, and the Megablock, which integrates the Megapack 3 with transformers and switchgear. Batteries were Tesla’s fastest growing business in the first quarter of this year, as Matthew reported in April, but the company feared that tariffs would affect the business. “The energy segment — which includes the company’s battery energy storage businesses for residences (Powerwall) and for utility-scale generation (Megapack) — has recently been a bright spot for the company, even as its car sales have leveled off and declined.”
Google inked a deal with the Salt River Project, the utility serving much of Arizona’s largest metropolis, to test the performance of long-duration energy storage projects. The first-of-a-kind research collaboration aims to “better understand the real-world performance of emerging non-lithium ion long duration energy storage technologies” in the Phoenix area, the power company said in a press release. Google will fund a portion of the costs and evaluate data on the pilot projects’ operational success. “We believe that long duration energy storage will play an essential role in meeting SRP’s sustainability goals and ensuring grid reliability,” Chico Hunter, the nonprofit Salt River Project’s manager of innovation and development, said in a statement.
As I reported in this newsletter in July, Google also backed the Italian carbon dioxide-based storage startup Energy Dome as the tech giant pushes to expand its portfolio of technologies to power its data centers 24/7.
The European Union has been a solid backer of fusion energy research. But the anti-nuclear trifecta of Germany, Austria, and Luxembourg has long thwarted bloc-wide efforts to bolster fission, which provides the bulk of the continent’s electricity. With Berlin finally joining Paris in backing traditional nuclear power, that blockade is no longer holding. The European Commission has proposed spending $11.5 billion on bolstering research in both fusion and fission, the trade publication NucNet reported Monday.
Meanwhile in the United States, where nuclear power remains broadly supported across the political spectrum, the biggest question is how quickly new reactors can come online. The data center industry has now called on the Nuclear Regulatory Commission to streamline licensing of new reactors to help meet its surging demand for electricity. In a letter to NRC Chair David Wright shared with E&E News, the Data Center Coalition, a trade group representing server farms, urged the agency to update its regulations to ensure quicker deployment of advanced reactors. “Increasingly, DCC members are forming strategic partnerships and committing to offtake agreements with utilities and nuclear technology developers, injecting new momentum into this strategic sector,” wrote Cy McNeill, the group’s director of federal affairs. “We are approaching the cusp of a truly revitalized nuclear sector.”
The push comes amid what Heatmap’s Katie Brigham called a “nuclear power dealmaking boom.”
Patagonia’s billionaire founder helped popularize the greenest trend in apparel — buying less of higher quality, longer-lasting clothing. Now the retailer is pushing to bring that same ethos to the food business. The company’s edible offerings of tinned fish and crackers designed for hiking is now expanding into baby foods, oils, and sauces, The New York Times reported in a new profile of the retailer. Fifty years from now, founder Yvon Chouinard told the newsletter, “I could see the food business being bigger than the apparel business.”
Add the Department of Transportation to the list of federal agencies waging what Heatmap’s Jael Holzman called “Trump’s total war on wind.” The Transportation Department said Friday it was eliminating or withdrawing $679 million in federal funding for 12 projects across the country designed to buttress development of offshore turbines. The funding included $427 million awarded last year for upgrading a marine terminal in Humboldt County, California, meant to be used for building and launching floating wind turbines. The list also included a $48 million offshore wind port on Staten Island, $39 million for a port near Norfolk, Virginia, and $20 million for a staging terminal in Paulsboro, New Jersey. “Wasteful, wind projects are using resources that could otherwise go towards revitalizing America’s maritime industry,” Secretary of Transportation Sean Duffy said in a statement. “Joe Biden and Pete Buttigieg bent over backwards to use transportation dollars for their Green New Scam agenda while ignoring the dire needs of our shipbuilding industry.”
It’s just the Trump administration’s latest attack on wind. The Department of the Interior has led the charge, launching a witch hunt against any policies perceived to favor wind power, de-designating millions of acres of federal waters for offshore wind development, and kicking off an investigation into bird deaths near turbines. Last month, the Department of Commerce joined the effort, teeing up future tariffs with its own probe into whether imported turbines pose a national security threat to the U.S. In response, the Democratic governors of New York, Massachusetts, Connecticut, Rhode Island, and New Jersey on Monday issued a statement calling on the administration “to uphold all offshore wind permits already granted and allow these projects to be constructed.”

In what the New York Times called a “sharp escalation” of its legal strategy to fend off liability for pollution, Exxon Mobil has countersued California, accusing the state’s landmark litigation over plastic waste of defaming the oil giant. At a court hearing last month, Exxon attorney Michael P. Cash described the lawsuit California Attorney General Rob Bonta and a cadre of environmental groups first filed last year as “an attack” aimed at the oil company’s home state of Texas and said the issue should be litigated there. As Times reporter Karen Zraick noted, Cash illustrated his point by displaying “a graphic showing a missile aimed at Texas from California” and by comparing Bonta and his nonprofit allies to “The Sopranos.”
Backed by a parallel lawsuit filed by the Sierra Club, Baykeeper, Heal the Bay, and the Surfrider Foundation, Bonta sued Exxon in state court on the grounds that the company had deceived Californians by “promising that recycling could and would solve the ever-growing plastic waste crisis,” alleging that the pollution had created a public nuisance and sought damages worth “multiple billions of dollars.” The lawsuit mirrors past litigation over planet-heating emissions, but targets the petrochemical division that has been one of the fastest-growing for Exxon and other oil giants. The courtroom drama came right as international negotiations in Geneva over a global treaty to curb plastic pollution failed after the United States joined Russia and other petrostates to block measures supported by more than 100 other nations that would have curbed production.
In North America, nuclear fuel may soon become harder to come by. Canadian uranium giant Cameco has warned that delays in ramping up production at its McArthur River mine in Saskatchewan could shrink its forecast output for the year. The move came just a week after one of the world’s other major suppliers of uranium, Kazakhstan’s state-owned miner Kazatomprom, announced plans to slash its production by 10% next year.
The pullback is happening right as the U.S. nuclear industry’s dealmaking boom is taking off. Now that Trump’s tax law assured that support for atomic energy would continue, Adam Stein from the Breakthrough Institute told Heatmap’s Katie Brigham that more reactor plans are coming. “We might have seen more deals earlier this year if there wasn’t uncertainty about what was going to happen with tax credits. But now that that’s resolved, I expect to hear more later this year,” he told Katie. That includes Europe. Despite similarly lethargic construction of reactors over the last three decades, France and Germany have finally united around the need for more atomic energy to power the continent’s energy transition. A pact signed at last week’s Franco-German summit “appears to herald rapprochement on reactors,” the trade publication NucNet surmised.
Once a stodgy gas-guzzling automaker, Cadillac refashioned itself as a luxury electric vehicle maker in recent years, rising alongside Chevrolet to put General Motors in the No. 2 slot behind Tesla. Roughly 70% of buyers who purchased the electric versions of the Cadillac Optiq or Lyriq switched from other luxury brands, including 10% who previously owned Tesla. That number could rise with Tesla’s brand loyalty nosediving, as this newsletter previously reported. “We’re in a position of great momentum,” John Roth, the global vice president of Cadillac, told The New York Times. “We offer more electric S.U.V.s than any luxury manufacturer, all with more than 300 miles of driving range.” But as Times reporter Lawrence Ulrich wrote, “that moment will soon be tested” as the electric car industry reels from the repeal of tax credits in President Trump’s One Big Beautiful Bill.
The challenges ahead are best illustrated through the Escalade, Cadillac’s iconic luxury SUV. The company sold just 3,800 electric Escalade IQs in the first six months of the year. While that’s a strong showing for a three-row SUV starting around $130,000, the V-8 engine gas-powered Escalade starts at about $87,000, and sold about 24,000 vehicles – roughly six times as many as the electric version.
Lawyers in Oregon are demanding the release of a firefighter arrested last week by Border Patrol while fighting a wildfire in Washington state. The man, whose name hasn’t been released, was among two firefighters cuffed in the Olympic National Forest as they fought to contain the Bear Gulch Fire that had burned about 14 square miles as of Friday and forced evacuations. The arrests sparked a political firestorm over what critics saw as a jarring example of the warped priorities of the Trump administration’s immigration crackdown. That’s particularly so in the case of this firefighter, who attorneys said had received his U-Visa certification from the U.S. Attorney’s Office in Oregon in 2017 and had submitted his U.S. Citizenship and Immigration Services application the following year.
When the AP asked the Bureau of Land Management why its contracts with two firefighting companies were terminated and 42 firefighters were escorted away from Washington’s largest wildfire, the agency declined to comment. The decisions came as the American West is essentially a tinderbox. As Heatmap’s Jeva Lange reported, Washington and Oregon are both at high risk of a megafire igniting this fall.
Turns out mammoths weren’t just in the icy tundra. Scientists in Mexico discovered mammoth bones, shedding light on a once-obscure population of extinct tropical elephantids that ranged as far south as Costa Rica. In a paper published this week in Science, National Autonomous University of Mexico paleogenomicist Federico Sánchez Quinto documented the previously unknown lineage of the Santa Lucía mammoths, which he said split from northern Columbian mammoths hundreds of thousands of years ago. “If you had told me 5 years ago that I would be collecting these samples, I would have said, ‘You’re crazy,’” he said. “This paper really is an exciting beginning of something.”
