Current conditions: Massive wildfires are still burning in the Texas Panhandle • Thailand’s “Royal Rainmaking” program starts today, in which planes seed clouds to induce artificial rain • It will be cold but sunny in Washington, DC, where a special hearing on the rights of people displaced by climate change is taking place.

THE TOP FIVE

1. Sierra Nevada braces for huge blizzard

A massive blizzard could dump up to 12 feet of snow on parts of the Sierra Nevada over the next few days. “Storm total snowfall from Thursday into early Sunday is currently projected at 5 to 10+ feet for elevations above 5,000 feet, locally higher amounts of 12+ feet are possible at peaks, with significant disruptions to daily life likely,” the National Weather Service said.

The storm threatens to close Donner Pass, the region’s main thruway, which usually sees 30,000 cars and 6,000 semi-trucks each day. Northern California, Oregon, and Washington state are all under winter storm warnings and wind advisories, with gusts over 55 mph expected.

2. Researchers see breakthrough progress on new kind of solar cell

Researchers out of MIT have published a “guidebook” for controlling and engineering perovskite solar cells. These cells could “redefine the solar energy landscape,” wrote Michelle Lewis at Electrek, “offering a tantalizing combination of high efficiency, low manufacturing costs, and the unique ability to be applied to a variety of substrates, from rigid glass to flexible materials.” But they degrade far too quickly, and struggle to maintain their efficiency in large modules, and these technical challenges have so far hampered their potential for commercial viability. In a new paper published in the journal Nature Energy, MIT researchers outline how to change the properties of the perovskite’s surface so that it maintains efficiency and lasts longer. “I think we are on the doorstep of the first practical demonstrations of perovskites in the commercial applications,” professor Vladimir Bulovic told MIT News. “And those first applications will be a far cry from what we’ll be able to do a few years from now.”

3. Apple workers reportedly nicknamed doomed EV ‘the Titanic disaster’

More details are emerging about Apple’s ill-fated self-driving electric vehicle, which was reportedly scrapped this week. The secret car – codenamed “Project Titan” – had been in the works since 2014, and was the company’s attempt to protect itself from an anticipated slow-down in iPhone sales. Entering the car market seemed an obvious next step for the company. “Apple would do to cars what it did to phones,” said Tim Higgins at The Wall Street Journal.

But after several starts and stops and at least four project leaders, most employees knew it was going to fail. They even nicknamed it “the Titanic disaster,” according to The New York Times. The project lacked clarity and identity. Was it a Tesla rival? A self-driving car? All of the above? “Project Titan’s ambitions became diminished, less compelling — from an electric, robot car, then just about perfecting autonomy, then just about an EV,” Higgins said.

One thing’s for sure, Project Titan was expensive, costing the company $10 billion in the end. “Developing the software and algorithms for a car with autonomous driving features proved too difficult,” the Times reported. With that car crash in its rear-view mirror, Apple plans to accelerate its work on generative AI.

4. New York sues world’s top meatpacker over net zero claims

New York state has filed a lawsuit against the world’s biggest meat producer, JBS USA, alleging the Brazil-based company has misled the public about its environmental impact, according to Bloomberg. JBS has promised to be net zero by 2040, but the filing claims the company cannot possibly reach this goal and has no plan to do so. Food production accounts for one third of global greenhouse gases, and livestock alone produces nearly 15% of all emissions. JBS has annual revenues of more than $50 billion and its supply chain relies on thousands of farms in the Amazon, many of which overlap on Indigenous land and conservation areas, reported The New York Times. Last year JBS was found to have one of the lowest integrity scores among major companies that have made climate pledges. It is currently trying to get its shares listed on the New York Stock Exchange, but has faced fierce opposition from environmentalists, U.S.-based beef producers, and both Democrats and Republicans.

  • 5. Oil and gas giants eye geothermal projects

    Major fossil fuel companies are investing big money in geothermal energy startups and projects, The Wall Street Journal reported. “Many of these companies are using the same technology employed by frackers, but instead of searching for oil and gas, they are looking for underground heat,” the Journal adds. That heat can be harnessed to provide constant carbon-free electricity, and startups like Fervo Energy are finding new ways to make drilling for geothermal energy much cheaper, as Heatmap’s Matthew Zeitlin recently reported. Fervo is raising $244 million in new funding, including $100 million from fossil fuel company Devon Energy. “Once the industry is proven, I would not be surprised for today’s oil-and-gas industry to either buy or build their way to be significant players in advanced geothermal,” said billionaire former Enron trader John Arnold.

    THE KICKER

    A new study suggests up to 90% of microplastics can be removed from drinking water if the water is boiled and then filtered.

    The Last Time America Tried to Legislate Its Way to Energy Affordability

    Lawmakers today should study the Energy Security Act of 1980.

    The past few years have seen wild, rapid swings in energy policy in the United States, from President Biden’s enthusiastic embrace of clean energy to President Trump’s equally enthusiastic re-embrace of fossil fuels.

    Where energy industrial policy goes next is less certain than any other moment in recent memory. Regardless of the direction, however, we will need creative and effective policy tools to secure our energy future — especially for those of us who wish to see a cleaner, greener energy system. To meet the moment, we can draw inspiration from a largely forgotten piece of energy industrial policy history: the Energy Security Act of 1980.

    THE TOP FIVE

    1. Trump halts construction on all offshore wind projects

    Just two weeks after a federal court overturned President Donald Trump’s Day One executive order banning new offshore wind permits, the administration announced a halt to all construction on seaward turbines. Secretary of the Interior Doug Burgum announced the move Monday morning on X: “Due to national security concerns identified by @DeptofWar, @Interior is PAUSING leases for 5 expensive, unreliable, heavily subsidized offshore wind farms!” As Heatmap’s Jael Holzman explained in her writeup, there are only five offshore wind projects currently under construction in U.S. waters: Vineyard Wind, Revolution Wind, Coastal Virginia Offshore Wind, Sunrise Wind, and Empire Wind. “The Department of War has come back conclusively that the issues related to these large offshore wind programs create radar interference, create genuine risk for the U.S., particularly related to where they are in proximity to our East Coast population centers,” Burgum told Fox Business host Maria Bartiromo.

    Google is on an AI hiring spree — and not just for people who can design chips and build large language models. The tech giant wants people who can design energy systems, too.

    Google has invested heavily of late in personnel for its electricity and infrastructure-related teams. Among its key hires is Tyler Norris, a former Duke University researcher and one of the most prominent proponents of electricity demand flexibility for data centers, who started in November as “head of market innovation” on the advanced energy team. The company also hired Doug Lewin, an energy consultant and one of the most respected voices in Texas energy policy, to lead “energy strategy and market design work in Texas,” according to a note he wrote on LinkedIn. Nathan Iyer, who worked on energy policy issues at RMI, has been a contractor for Google Clean Energy for about a year. (The company also announced Monday that it’s shelling out $4.5 billion to acquire clean energy developer Intersect.)
