Current conditions: King tides are raising ocean levels near Charleston, South Carolina, as much as eight feet above low water averages • A blizzard on Mount Everest has trapped hundreds of hikers and killed at least one • A depression that could form into Tropical Storm Jerry is strengthening in the Atlantic as it barrels northward with an unclear path.


THE TOP FIVE

1. Global solar and wind generation overtake coal for the first time

Solar and wind outpaced the growth of global electricity demand in the first half of 2025, vaulting renewables toward overtaking coal worldwide for the first time on record, according to analysis published Tuesday by the research outfit Ember. This year’s growth resulted in a small overall decline in both coal and gas-fired power generation, with India and China seeing the most notable reductions, despite the United States and Europe ratcheting up fossil fuel usage. “We are seeing the first signs of a crucial turning point,” Malgorzata Wiatros-Motyka, a senior electricity analyst at Ember, said in a statement. “Solar and wind are now growing fast enough to meet the world’s growing appetite for electricity. This marks the beginning of a shift where clean power is keeping pace with demand growth.”

Wind and solar installations matched 109% of new global demand for power in the first half of 2025.Ember

That growth is projected to continue. Later on Tuesday morning, the International Energy Agency released its own report forecasting that renewable capacity will double over the next five years. Solar is predicted to make up 80% of that growth. But, factoring in the Trump administration’s policies, the forecast roughly cut in half previous projections for U.S. growth. Domestic opposition to renewables runs beyond the White House, too. Exclusive data gathered by Heatmap Pro and published in July showed that a fifth of U.S. counties now restrict development of renewables.

2. Trump orders controversial Alaska mining road to move forward

President Donald Trump signed an executive order Monday directing federal agencies to push forward with a controversial 211-mile mining road in Alaska designed to facilitate production of copper, zinc, gallium, and other critical minerals. The project, which the Biden administration halted last year over concerns for permafrost in the fast-warming region, has been at the center of a decadeslong legal battle. As part of the deal, the U.S. government will invest $35.6 million in Alaska’s Ambler Mining District, including taking a 10% stake in the main developer, Trilogy Metals, that includes warrants to buy an additional 7.5% of the company. The road itself will be jointly owned by the state, the federal government, and Alaska Native villages. “It’s a very, very big deal from the standpoint of minerals and energy,” Trump said in the Oval Office.

It’s just the latest stake the Trump administration has taken in a mineral company. In July, the Department of Defense became the largest shareholder of MP Materials, the company producing rare earths in the U.S. at its Mountain Pass mine in California. The move, The Economist noted at the time, marked the biggest American experiment in direct government ownership since the nationalization of the railroads in World War I. Last week, the Department of Energy renegotiated a loan to Lithium Americas’ Thacker Pass project in Nevada to take a stake in what’s set to become the largest lithium mine in the Western Hemisphere when it comes online in the next few years. The White House’s mineral shopping spree isn’t over. On Friday, Reuters reported that the administration is considering buying shares in Critical Metals, the company looking to develop rare earths production in Greenland. In response to the news, shares in the Nasdaq-traded miner surged 62% on Monday. Partial nationalization isn’t the only approach the administration is taking to challenging China’s grip over global mineral supplies. Last month, as I reported for Heatmap, the Defense Logistics Agency awarded money to Xerion, an Ohio startup devising a novel way to process cobalt and gallium.

3. Tesla set to roll out a cheaper Model Y — plus a surprise

Tesla looks poised to unveil a cheaper, stripped-down version of its Model Y as early as today. In one of two short videos posted to CEO Elon Musk’s X social media site, the electric automaker showed the midsize SUV’s signature lights beaming through the dark. The design matches what InsideEVs noted were likely images of the prototype spotted on a test drive in Texas. The second teaser video showed what appears to be a fast-spinning, Tesla-branded fan. “Your guess is as good as ours as to what will be revealed,” InsideEVs’ Andrei Nedelea wrote Monday. “Our money is on the Roadster or a new vacuum cleaner design to take on Dyson.”

The new products come amid an historic slump for Tesla. As Heatmap’s Matthew Zeitlin reported, the company’s share of the U.S. electric vehicle sales sank to their lowest-ever level in August despite the surge in purchases as Americans rushed to use the federal tax credits before they expired thanks to Trump’s landmark One Big Beautiful Bill Act law. Yet Musk has managed to steer the automaker’s financial fate through an attention-grabbing maneuver. Last month, the world’s richest man bought $1 billion in Tesla shares in a show of self confidence that managed to rebound the company’s stock price. But Andrew Moseman argued in Heatmap that “the bullish stock market performance is divorced not only from the reality of the company’s electric car sales, but also from, well, everything else that’s happened lately.”

4. Heavy duty trucks come in for tariffs

On Monday, Trump warned that medium and heavy-duty trucks imported to the U.S. will face a 25% tariff starting on November 1. The president announced the trade levies in a post on Truth Social on the eve of a White House visit by Canadian Prime Minister Mark Carney, whose country would feel the pinch of tariffs on imported trucks. As the Financial Times noted, Trump had threatened to impose 25% tariffs on some trucks in late September but “failed to implement them, raising questions about his commitment to the policy.”

5. Fusion faces serious supply chain challenges

Fusion startups make a lot of bold claims about how soon a technology long dismissed as the energy source of tomorrow will be able to produce commercial electrons. Though investors are betting that, as Heatmap’s Katie Brigham wrote last year, “it is finally, possibly, almost time for fusion,” a new report from the University of Pennsylvania’s Kleinman Center for Energy Policy shows that supply chain challenges threaten to hold back the nascent industry even if it can bring laboratory breakthroughs to market. Tritium, one of two main fusion fuels, has a half life of just 12.3 years, meaning it does not exist in significant quantities in nature. Today, tritium is primarily produced by 30 pressurized heavy water fission reactors globally, but only at a total of 4 kilograms per year. As a result, “tritium availability could throttle fusion development,” the report found. That’s not the only bottleneck. “The fusion industry will require specialized components that don’t yet have well-established supply chains, like superconducting cables and the aforementioned advanced materials, and shortages of these components would delay development and inflate costs.”

THE KICKER

Scientists mapped the RNA — the molecules that carry out DNA’s instructions — of wheat and, for the first time, identified when certain genes are active. The discovery promises to accelerate plant breeders’ efforts to develop more resilient varieties of the world’s most widely cultivated crop that use less fertilizer, resist higher temperatures, and survive with less water as the climate changes. “We discovered how groups of genes work together as regulatory networks to control gene expression,” Rachel Rusholme-Pilcher, the study’s lead author and a researcher at Britain’s Earlham Institute, said in a statement. “Our research allowed us to look at how these network connections differ between wheat varieties, revealing new sources of genetic diversity that could be critical in boosting the resilience of wheat.”

Climate Tech

This Fusion Company Is Already Making Money

Shine Technologies is getting close to breakeven — on operations, at least — by selling neutrons and isotopes.

Amidst the frenzied investment in fusion and the race to get a commercial reactor on the grid by the 2030s, one under-the-radar fusion company has been making money for years. That’s Shine Technologies, which has been operating in some form or another since 2005, making neutrons for materials testing and nuclear isotopes for medical imaging, all while working toward an eventual energy-generating reactor of its own.

“I think we can moonshot ourselves to net energy,” Greg Piefer, founder and CEO of Shine, told me, referring to the point at which the energy produced from a fusion reaction exceeds the energy required to sustain it. “But I don’t think we can moonshot ourselves to break even costwise.”

California’s Big Climate and Energy Package, Explained

The state quietly refreshed its cap and trade program, revamped how it funds wildfire cleanup, and reorganized its grid governance — plus offered some relief on gas prices.

California is in the trenches. The state has pioneered ambitious climate policy in the United States for more than two decades, and each time the legislature takes up the issue, the question is not whether to expand and refine its strategy, but how to do so in a politically and economically sustainable way.

With cost of living on everyone’s minds — California has some of the highest energy costs in the country — affordability drove this year’s policy negotiations. After a bruising legislative session, however, California emerged in late September with six climate bills signed into law that attempt to balance decarbonization with cost-reduction measures — an outcome that caught many climate advocates off guard.

Current conditions: A warm front coming from the Southwest is raising temperatures up to 30 degrees Fahrenheit above average across the Upper Midwest • A heat wave nearly 200 miles north of Montreal in La Tuque, Quebec, is sending temperatures to nearly 80 degrees today • Typhoon Matmo has made landfall in southern China, forcing thousands to evacuate amid peak holiday season.


THE TOP FIVE

1. The U.S. wind industry’s latest defender? Big Oil.

The United States’ beleaguered offshore-wind industry has found a new ally in its effort to fend off President Donald Trump’s assault: Big Oil. On Sunday, the Financial Times published an interview with Shell’s top executive in the U.S., in which she called the administration’s decision to halt permitting on seaborne turbines “very damaging” to investment and warned that a future Democratic president could use the precedent Trump set to attack the oil and gas industry. “However far the pendulum swings one way, it’s likely that it’s going to swing just as far the other way,” Colette Hirstius, president of Shell USA, told the newspaper when asked about the Trump administration’s stop-work orders on offshore wind farms. “I certainly would like to see those projects that have been permitted in the past continue to be developed. Similarly, if you think of the business I run offshore [Gulf of Mexico], that type of permitting uncertainty has been utilized to undermine the permits that we have in the past — and that’s equally as damaging.”
