The Heat Dome Lingers

On life-threatening temperatures, New York’s nuclear ambitions, and cancelled clean energy projects

Current conditions: Monsoon conditions are bringing flash floods to New Mexico • A heat warning has been issued in Beijing as temperatures creep toward 100 degrees Fahrenheit • It's hot and dry in Tehran today as a tenuous ceasefire between Iran and Israel comes into effect.

THE TOP FIVE

1. Hochul calls for new nuclear power plant in New York

New York Governor Kathy Hochul announced on Monday that she wants to bring new, public nuclear power back to the state. She directed the New York Power Authority, the state power agency, to develop at least 1 gigawatt of new nuclear capacity upstate. Hochul did not specify a design or even a location for the new plant, but based on a few clues in the press release and where Hochul chose to make the announcement, Heatmap’s Matthew Zeitlin speculates that the project could be a small modular reactor, specifically GE Hitachi’s BWRX-300, one of a handful of SMR designs vying for both regulatory approval and commercial viability in the U.S. “Canada’s Ontario Power Generation recently approved a plan to build one,” Zeitlin notes, “with the idea to eventually build three more for a total 1.2 gigawatts of generating capacity, i.e. roughly the amount Hochul’s targeting.”

The announcement comes at a time when the federal regulatory and tax balance is tipping toward nuclear. The Trump administration issued a fleet of executive orders looking to speed up nuclear construction and regulatory approvals, and Senate Republicans’ version of the mega budget reconciliation bill includes far more generous treatment of nuclear development compared to wind and solar.

2. Temperatures soar as punishing heat dome lingers

The heat dome that’s moving slowly across the U.S. is bringing dangerous conditions to millions of Americans. Multiple cities across the Midwest and East Coast felt hotter than 100 degrees Fahrenheit yesterday, including Chicago, Nashville, and Raleigh. Roads buckled in Missouri. In New York’s Staten Island, the heat index hit 113 degrees. “This is life-threatening,” NYC Emergency Management said in a post on X. “At this level, the human body struggles to cool itself. Prolonged exposure or physical activity can quickly lead to heat stroke.” Power outages were reported in parts of the city. New York Mayor Eric Adams urged residents to help relieve the strain on the electric grid by avoiding using large appliances in the middle of the day, turning off lights, and limiting unnecessary air conditioning use. Wholesale energy prices soared as use skyrocketed. According to AccuWeather, more than 160 daily high temperature records could fall this week before things cool down Wednesday. Nearly 150 million people are affected by some kind of heat alert, and about 10% of the nation’s population will endure temperatures at or above 100 degrees today.

  • 3. Nearly $1.5 billion in clean energy projects were cancelled in May

    About $1.4 billion in clean energy projects were cancelled last month as policy uncertainty mounts and the GOP’s budget reconciliation megabill hacks away at clean energy tax credits and permitting reform. According to a new report from clean energy business group E2, $15.5 billion in new factories and electricity projects have been nixed since the start of 2025, along with the 12,000 new jobs those projects were expected to create. “Republican congressional districts are losing the most,” the report finds. “More than $9 billion in investments and almost 10,000 jobs have been cancelled, delayed, or closed in Republican districts so far in 2025.”

    4. Renewables capacity still not on track to triple by 2030: report

    The world added 741 gigawatts of renewable energy capacity last year, according to the new Renewables Global Status Report from Paris-based think tank REN21. That’s a new record, but it still falls far short of the COP28 goal to triple renewables capacity by 2030. In fact, “current trajectories suggest a shortfall of 6.2 terawatts – more than all renewables deployed to date,” the report finds. Here are some other key takeaways:

    • Global energy demand rose 2.2% in 2024 and electricity use was up 4.3% compared to the year before.
    • Coal-powered electricity reached an all-time high, but its annual growth rate is slowing.
    • Energy-related carbon dioxide emissions rose by 0.8%.
    • Power generation from renewables increased by 10%.
    • China accounted for 60% of the new renewables capacity.
    • Solar made up 81% of new renewables capacity, but its annual growth rate fell to 32%, down from 82% in 2023.
    • Global renewables investment grew 8% in 2024, down from the 19% increase seen in 2023. The report notes that the main reason for the decline is a drop in wind power investment.
    • $772 billion more is needed in investment by 2030 to reach the COP28 goal of tripling renewable energy capacity.

    5. Trump ending protections for 58 million acres of forest

    The Trump administration will roll back protections for nearly 60 million acres of pristine national forest, Agriculture Secretary Brooke Rollins announced Monday. Rescinding the 2001 “Roadless Rule” will open vast swathes of the nation’s forests — including Tongass National Forest in Alaska, which is North America’s largest temperate rainforest — to industrial activities. The administration called the rule “overly restrictive,” and said rolling it back will allow for better fire prevention and “responsible” timber production. The logging industry applauded the announcement; conservation groups condemned it. The rollback is likely to be challenged in court.

    THE KICKER

    “I now believe that cleaning up methane leaks from the production and shipping of oil and gas — one of the most significant sources of these emissions — is the best hope we have to avoid triggering some of the most consequential climate tipping points in the next decade. I think realistically it is our only hope.”Carl Pope, former executive director of the Sierra Club, on his biggest regrets as an environmentalist.

    THE TOP FIVE

    1. Trump threatens 35% tariff on Canada

    President Trump threatened a 35% tariff on Canadian imports on Thursday, giving Prime Minister Mark Carney a deadline of August 1 before the levies would go into effect. The move follows months of on-again, off-again threats against Canada, with former Canadian Prime Minister Justin Trudeau having successfully staved off the tariffs during talks in February. Despite those earlier negotiations, Trump held firm on his 50% tariff on steel and aluminum, which will have significant implications for green manufacturing.

    The Software That Could Save the Grid

    Or at least the team at Emerald AI is going to try.

    Everyone’s worried about the ravenous energy needs of AI data centers, which the International Energy Agency projects will help catalyze nearly 4% growth in global electricity demand this year and next, hitting the U.S. power sector particularly hard. On Monday, the Department of Energy released a report adding fuel to that fire, warning that blackouts in the U.S. could become 100 times more common by 2030 in large part due to data centers for AI.

    The report stirred controversy among clean energy advocates, who cast doubt on that topline number and thus the paper’s justification for a significant fossil fuel buildout. But no matter how the AI revolution is powered, there’s widespread agreement that it’s going to require major infrastructure development of some form or another.

    EPA Claims Congress Killed the Green Bank

    The saga of the Greenhouse Gas Reduction Fund takes another turn.

    On July 3, just after the House voted to send the reconciliation bill to Trump’s desk, a lawyer for the Department of Justice swiftly sent a letter to the U.S. Court of Appeals for the D.C. Circuit. Once Trump signed the One Big Beautiful Bill Act into law, the letter said, the group of nonprofits suing the government for canceling the biggest clean energy program in the country’s history would no longer have a case.

    It was the latest salvo in the saga of the Greenhouse Gas Reduction Fund, former President Joe Biden’s green bank program, which current Environmental Protection Agency Administrator Lee Zeldin has made the target of his “gold bar” scandal. At stake is nearly $20 billion to fight climate change.
