THE TOP FIVE
1. Orsted sells new shares at a steep discount
Orsted is offering investors a nearly 70% discount on the new shares issued to raise money to save its American offshore wind projects amid the Trump administration’s aggressive crackdown on the industry. The Danish energy giant won nearly unanimous approval from its shareholders earlier this month for a rights issue aimed at raising $9.4 billion. Shares in the company, which is half owned by the government in Copenhagen, closed around $32 each on Friday. But the offering of 901 million new shares came at a subscription rate of about $10.50 each. Orsted’s projects in the northeastern U.S. already “struggled” with what The Wall Street Journal listed as “supply-chain bottlenecks, higher interest rates, and trouble getting tax credits,” which culminated in the restructuring last year that saw the company “pull out of two high-profile wind projects off the coast of New Jersey.”
The offshore wind industry, as I noted in yesterday’s newsletter, is just starting to fight back. The owners of the Rhode Island offshore project Revolution Wind, which Trump halted unilaterally, filed a lawsuit claiming the administration illegally withdrew its already-finalized permits. After the administration filed a lawsuit to revoke the permits of US Wind’s big project off Maryland’s coast, the company said it intends “to vigorously defend those permits in federal court, and we are confident that the court will uphold their validity and prevent any adverse action against them.” But the multi-agency assault on offshore turbine projects has only escalated in recent months, as the timeline Heatmap’s Emily Pontecorvo produced shows. And Orsted is facing other headwinds. The company just warned investors of lower profits this year after weaker-than-forecast wind speeds reduced the output of its turbines.
2. Toyota halts U.S. EV sales amid recall of nearly 600,000 vehicles
Toyota issued a voluntary recall for some 591,000 Toyota and Lexus cars over a slight glitch in the display screen. The 12.3-inch screen could fail to turn on after the car started, or go black while driving. Toyota said it will begin notifying owners if affected vehicles by mid-November. The move came just days after the Japanese auto giant — which owns both its eponymous passenger car brand and the associated luxury line, Lexus — recalled 62,000 electric vehicles, including the Toyota bZ4X SUV and the Lexus RZ300e sedan and its luxury SUV, the RZ450. Subaru, in which Toyota owns a minority stake, is also recalling its electric SUV, the Solterra. With all four EVs, the issue revolved around a faulty windshield defroster that “may not remove frost, ice and/or fog from the windshield glass due to a software issue in the electrical control unit,” the company said in a press release..
3. Americans’ per-capita energy emissions fell in every state

Americans who complain that the U.S. should bear less responsibility for mitigating climate change like to point out that China produces far more planet-heating emissions per year, and that India is not far behind. The cumulative nature of carbon in the atmosphere makes for an easy rebuke, since the U.S. and Western Europe are overwhelmingly responsible for the emissions of the past two centuries. But a less historically abstract response could be that Americans still have by far the highest per capita emissions of any large country. That doesn’t mean the U.S. isn’t making progress on a per capita level, though. Between 2005 and 2023, per capita emissions from primary energy consumption decreased in every U.S. state, with an average drop of 30%, even as the American population grew by 14%, according to a new analysis by the U.S. Energy Information Administration. The dip is largely thanks to the electric power sector burning less coal. Increased electricity generation from natural gas, which releases about half as much carbon per unit of energy when burned as coal, and the growth of renewables such as wind and solar have reduced the need for the dirtier fuel. But the EIA forecasts that overall U.S. emissions are set to climb by 1% as electricity demand increases.
For those keen to shrink their individual carbon output at a much faster pace than American society at large, Heatmap’s award-winning Decarbonize Your Life series walks through the benefits and drawbacks to driving less, eating less steak, installing solar panels, and renovating homes to be more energy efficient.
4. Sierra Club names new leader
Following rebellions from various state chapters, the Sierra Club terminated its executive director, Ben Jealous, last month, as I reported here in this newsletter at the time. Now the group has named its new leader: Loren Blackford. The Sierra Club veteran, who served in various senior roles before taking on the interim executive director job last month, won unanimous support from the group’s board of directors on Saturday.
Jealous had previously served as a chief executive of the National Association for the Advancement of Colored People and the 2018 Democratic nominee for Maryland governor before becoming the first non-white leader of the 133-year-old Sierra Club. His appointment marked a symbolic turning of the page from the group’s early chapters under its founder, John Muir, who made numerous derogatory remarks about Black and Native Americans. Jealous was accused of sexual harassment earlier this year.
5. Thermal battery startup Fourth Power raises $20 million
Thermal battery company Fourth Power just announced $20 million in follow-on funding, building on its $19 million Series A round from 2023. While other thermal storage companies such as Rondo and Antora are targeting the decarbonization of high-temperature industrial processes such as smelting or chemical manufacturing, Fourth Power aims to manufacture long-duration energy storage systems for utilities and power producers.
“In our view, electricity is the biggest problem that needs to be solved,” Fourth Power’s CEO Arvin Ganesan told Heatmap’s Katie Brigham. “There is certainly a future application for heat, but we don’t think that’s where to start.” The company’s tech works by taking in excess renewable electricity from the grid, which is used to heat up liquid tin to 2,400 degrees Celsius, nearly half the temperature of the sun’s surface. That heat is then stored in carbon blocks and later converted back into electricity using thermophotovoltaic cells. This latest funding will accelerate the deployment of the startup’s first one megawatt hour demonstration plant.
THE KICKER
The tropical storm that later became Hurricane María formed exactly eight years ago today and went on to lay waste to Puerto Rico’s aging electrical system. The grid remains fragile and expensive, with frequent outages and some of the highest rates in the U.S. on the hours when the power is accessible. That has spurred a boom in rooftop solar panels. Now more than 10% of the island’s electricity consumption comes from rooftop solar power. Data released by the grid operator LUMA Energy showed approximately 1.2 gigawatts of residential and commercial rooftop solar had been installed under Puerto Rico’s net-metering regulations as of June 2025. New analysis by the Institute for Energy Economics and Financial Analysis found that is equal to about 10.3% of Puerto Rico’s total power consumption — and that’s not counting any off-grid systems.
