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.

    How the Shutdown Could Remake the Trump Administration

    Republicans have blamed Democrats for unleashing Russ Vought on federal spending. But it doesn’t take much to see a bigger plan at work.

    Russ Vought, the director of the Office of Management and Budget, has been waiting for this moment his whole adult life — or that’s what President Trump and the Republican Congressional leadership would like you to believe. As they put it, Vought is a fanatical budget cutter who, once unleashed, cannot be controlled. Who knows what he’ll cut if the Democrats continue to keep the government shut down?

    Substantial staffing cuts that go beyond the typical shutdown furloughs are “the risk of shutting down the government and handing the keys to Russ Vought,” Senate Majority Leader John Thune told Politico on Thursday. “We don’t control what he’s going to do.”

    Data Centers Collide with Local Restrictions on Renewables

    A review of Heatmap Pro data reveals a troubling new trend in data center development.

    Data centers are being built in places that restrict renewable energy. There are significant implications for our future energy grid – but it’s unclear if this behavior will lead to tech companies eschewing renewables or finding novel ways to still meet their clean energy commitments.

    In the previous edition of The Fight, I began chronicling the data center boom and a nascent backlash to it by talking about Google and what would’ve been its second data center in southern Indianapolis, if the city had not rejected it last Monday. As I learned about Google’s practices in Indiana, I focused on the company’s first project – a $2 billion facility in Fort Wayne, because it is being built in a county where officials have instituted a cumbersome restrictive ordinance on large-scale solar energy. The county commission recently voted to make the ordinance more restrictive, unanimously agreeing to institute a 1,000-foot setback to take effect in early November, pending final approval from the county’s planning commission.

    1. Energy Department kills West Coast hydrogen hubs

    The Department of Energy is canceling two regional hydrogen hubs in California and the Pacific Northwest as part of a broader rescinding of 321 grants worth $7.5 billion for projects nationwide. Going after the hydrogen hubs, which the oil and gas industry lobbied to keep open after President Donald Trump came back to office, “leaves the agency’s intentions for the remaining five hubs scattered throughout the Midwest, Midatlantic, Appalachia, the Great Plains, and Texas unclear,” Heatmap’s Emily Pontecorvo wrote yesterday.
