Current conditions: Tropical Erin is expected to gain strength and make landfall in the Caribbean as the first major hurricane of the season, lashing islands with winds of up to 80 miles per hour and 7 inches of rain • More than 152 fires have broken out across Greece in the past 24 hours alone as Europe battles a heatwave • Typhoon Podul is expected to make landfall over southeastern Taiwan on Wednesday morning, lashing the island with winds of up to 96 miles per hour.

THE TOP FIVE

1. Energy Department selects 11 nuclear projects for pilot program

The Department of Energy selected 11 nuclear projects from 10 reactor startups on Tuesday for a pilot program “with the goal to construct, operate, and achieve criticality of at least three test reactors” by next July 4. The Trump administration then plans to fast-track the successful technologies for commercial licensing. The effort is part of the United States’ attempt at catching up with China, which last year connected its first high-temperature gas-cooled reactor to the grid. The technologies in the program vary among the reactors selected for the program, with some reactors based on Generation IV designs using coolants other than water and others pitching smaller but otherwise traditional light water reactors. None of the selected models will produce more than 300 megawatts of power. The U.S. hopes these smaller machines can be mass produced to bring down the cost of nuclear construction and deploy atomic energy in more applications, including on remote military bases, and even, as NASA announced last week, the moon.

Here are the companies:

  • Aalo Atomics
  • Antares Nuclear
  • Atomic Alchemy
  • Deep Fission
  • Last Energy
  • Oklo (named two projects)
  • Natura Resources
  • Radiant Industries
  • Terrestrial Energy
  • Valar Atomics

2. Sierra Club fires leader after contentious tenure

The Sierra Club terminated executive director Ben Jealous this week, ending a rocky tenure that culminated earlier this summer in votes of no confidence among statewide chapters, Inside Climate News’ Lee Hedgepeth reported. A former chief executive of the National Association for the Advancement of Colored People and the 2018 Democratic nominee for Maryland governor, Jealous’ rise to the green group’s top job in November 2022 seemed like a watershed moment for what is arguably the nation's most prominent environmental groups. The first non-white leader of the 133-year-old organization promised to close the book on the Sierra Club’s internal wrestling with the racist legacy of its founder, John Muir.

But budget cuts, layoffs, and fights with the group’s union marred his time at the helm. In June, the executive committee of the Sierra Club’s Oregon Chapter voted unanimously to request a vote of no-confidence in Jealous from the national organization’s board, citing his hiring of a senior staff member who was registered as lobbyist for the cryptocurrency exchange Crypto.com, The New York Times’ Claire Brown reported. Weeks later, the Missouri Chapter voted unanimously to make the same request. Allies on the board accused Jealous’ critics of a racist “pattern of misinformation, character assassination, and discrimination” against the first Black man to hold the top job. But the board placed Jealous on leave last month and, on Monday, said in a statement that it had “unanimously voted to terminate Ben Jealous’ employment for cause.”

  • 3. One Big Beautiful Bill already raising costs of electricity deals

    The price of power purchase agreements in the U.S. has increased by 4% on average since the passage of President Donald Trump’s One Big Beautiful Bill. That’s according to data released this morning by the industry group LevelTen Energy, which called the calculations “the clearest signal yet that the market has already begun to reprice in light of these new risks and headwinds.”

    Of the 86 U.S. developers surveyed from the LevelTen Marketplace, 86% said “they are now adapting their approach — either by accelerating construction timelines, reprioritizing project pipelines, or both.” Next Monday, the Treasury Department is due to issue guidance for renewable energy projects accessing federal tax credits, following Trump’s executive order directing the Internal Revenue Service to place new restrictions on solar and wind developers. Industry groups have been “circling the wagons” since the orders release, according to Heatmap’s Emily Pontecorvo, bracing for restrictions that will push up prices for renewables.

    4. Trump’s push for deep-sea mining draws international blowback

    The United States is the only major country that hasn’t ratified the United Nations’ 1994 Law of the Sea treaty. Yet the Trump administration has used the country’s “observer” status to push for finalizing a code under the UN-affiliated International Seabed Authority that would allow for permitting commercial mining on the ocean floor. Trump also signed an executive order in April to unilaterally license deep-sea mining if global rules don’t come into effect. At the center of the effort is the Canadian startup The Metals Company, which has designed special machines to harvest mineral-rich nodules on the deep-sea floor. The company and its backers say it’s a cleaner, faster way to increase global mineral supplies than opening more mines on land. But skeptics — including France and China — warn that the rush to industrialize one of the planet’s last untouched wildernesses risks harming fragile and scarcely understood ecosystems, and criticized Washington for threatening to go it alone without international regulations in place.

    China was the first country to publicly condemn Trump’s order in April, but Brazil and Panama spoke at last month’s ISA meeting in Kingston, Jamaica, to express support for Beijing’s position, Canary Media’s Clare Fieseler reported from the Caribbean capital.

    5. 2025 is on track to be one of the five hottest years on record

    Temperature records are smashed so frequently nowadays that last month’s bronze-medal status as the third-warmest July since recordkeeping began in 1850 is easy to shrug off. But the latest monthly forecasting from NOAA contains some more alarming findings. The year-to-date period, from January to July, has been the second-warmest on record for the planet, and only 0.10 degrees Celsius cooler than 2024. As Yale Climate Connections put it: “Based on statistical patterns drawn from prior monthly and annual data, NOAA is now giving this year a less-than-1% chance of winding up as the warmest year on record, but a greater-than-99% chance of being among the top-five warmest years.”

    THE KICKER

    Great news for anyone who, like me, is getting increasingly spooked about microplastics: New research in the journal Sustainable Food Technology found that grapevine cane films could be a great alternative to petrochemical plastics. They’re transparent, leave behind no harmful residues, and biodegrade into soil within 17 days. “These films demonstrate outstanding potential for food packaging applications,” Srinivas Janaswamy, an associate professor in South Dakota State University's Department of Dairy and Food Science, said in a press release. “That is my dream.

    Editor’s note: This story has been corrected to reflect the fact that, at the time of publication, Tropical Storm Erin was not yet a hurricane.

    Europe Braces for Energy Cuts as Rivers Heat and Dry Up

    Current conditions: The unusual humidity thickening the Los Angeles air this week is the result of a warmer Pacific Ocean, a sign of climate change • Temperatures are topping triple digits Fahrenheit in the Spanish capital of Madrid • Severe storms are pummeling the central United States from the Plains to Appalachia.

    THE TOP FIVE

    1. Europe braces for energy cuts as rivers heat and dry up

    The latest heat wave roasting Europe is warming up rivers and drying the watercourses on which the continent’s energy systems rely. In Eastern Europe, the mighty Danube has hit record lows, beaching boats in Croatia, squeezing out a quarter of Serbia’s fuel shipments, and forcing Hungary’s only nuclear power station to shut down as cooling water disappeared. The cost of navigating the barges that ship petroleum products, chemicals, coal, and steel down the Rhine river skyrocketed 400% in the last two months as water levels plummeted, as Bloomberg columnist Javier Blas pointed out. Economists warned the German broadcaster DW this week that the Rhine’s low levels could slash as much as 0.2% off Germany’s entire economic output in the third quarter of this year. It’s a stark reminder of what Heatmap contributor Hazel Southwell wrote back in 2023: Economies aren’t ready for rivers to dry up.

    Exclusive: Over 530 Local Laws Now Seek to Ban or Restrict Data Centers

    The overwhelming majority of the ordinances were enacted this year, a Heatmap Pro review shows. They’re helping to drive an unprecedented surge of data center cancellations.

    America’s data center backlash is gaining steam.

    Anti-data-center protesters briefly interrupted President Trump’s speech at a General Motors facility in Michigan earlier this week. A day later, the country music legend Willie Nelson called on Americans to “fight against data centers invading our land.”

    Washington has yet to pass major data center regulation. But the backlash is already reshaping local zoning and land use codes across the country, according to an extensive review of public records conducted by Heatmap Pro. A surge of new restrictions and bans have killed dozens of proposed data centers this year.

    More than 500 counties or municipalities now actively restrict or block new data centers, according to the review. This tally includes only the most severe constraints — such as steep setback requirements, impossible noise limits, or outright bans on permit approvals — that all but forbid the construction of a data center.

    The overwhelming majority of these restrictions have been enacted since the beginning of the year. Nearly 190 have been passed since June 1.

    The pace of moratoriums is “accelerating,” Peter Freed, a founding partner at the Near Horizon Group and the former director of energy strategy at Meta, told me.

    Broadly, these new local restrictions seem to be succeeding. More than 50 data centers have been canceled so far this year after facing local pushback of some kind, according to a Heatmap Pro review of press accounts, public records, and project cancellations.

    That’s more than twice as many projects as were canceled under similar circumstances in all of 2025, according to our data. Eight projects were canceled in July alone.

    Ominously for developers, the rate of projects facing cancellations seems to be increasing over time.

    1. Commonwealth Fusion Systems raises another $1 billion

    Last month, I toured Commonwealth Fusion Systems’ headquarters in small-town central Massachusetts. The place was abuzz in activity. On the factory floor side, workers were assembling the magnets needed to ultimately form the torus-shaped reactor — think a giant doughnut with an interior that curves like the core of an apple — called the tokamak. On the actual reactor side, SPARC — the prototype that CFS expects will make history next year as the first private enterprise and only tokamak to ever generate more energy that it took to start the fusion reaction — was starting to look like a functional machine from my view on a second-story walkway overlooking the sterile assembly room. The old joke that fusion is the energy source of tomorrow — and always will be — certainly didn’t ring as funny now. I’ll tell you who isn’t laughing: All the new investors that just poured another $1 billion into CFS. The company announced its latest funding round early this morning, which brings the startup’s total fundraising since its launch as a spinout from the Massachusetts Institute of Technology in 2018 to $4 billion. CFS now accounts for 30% of all the private capital that has flowed into fusion. What distinguishes this round, my colleague Katie Brigham wrote, is that the money is coming from a bunch of institutional investors, such as pension funds and sovereign wealth funds, rather than venture capitalists. On a call with reporters this week, CFS’s newly-named chief financial officer, Lorence Kim, said it’s the first-time institutional investors comprised the majority of the new funding. When I asked the company’s spokeswoman for a percentage estimate breaking down the new versus old investors in this round, she declined to comment. Kim cautioned that the funding isn’t the kind of capital you raise before launching on a stock market. But his hire is notable. The former Goldman Sachs banker famously helped take the pharmaceutical giant Moderna public and held the top financial role through the start of the Covid-19 pandemic.
