Current conditions: The western U.S. is in the midst of a severe “snow drought” • The Great Lakes began 2024 with their smallest amount of ice cover in 50 years • Finland’s Enontekiö airport recorded the country’s coldest January temperature since 2006: -44 degrees Fahrenheit.

THE TOP FIVE

1. Offshore wind sees a turbulent start to 2024

“The rollercoaster that is the U.S. offshore wind industry is already racing in 2024,” says Canary Media’s Maria Gallucci. Indeed, after missing an end-of-year deadline to start sending energy to the U.S. grid, the nation’s first large-scale offshore wind farm came online at 11:52 p.m. on Tuesday, delivering five megawatts of power to the New England grid. The Vineyard Wind 1 project, located near Martha’s Vineyard, will eventually consist of 62 turbines capable of powering 400,000 homes in Massachusetts.

“The arrival of Vineyard Wind is a welcome tonic to a nascent offshore wind industry that has struggled in the US in recent months,” writes Oliver Milman at The Guardian. But on Wednesday, BP and Equinor abandoned a contract to sell offshore wind energy to the state of New York, citing the familiar headwinds of rising costs, interest rates, and supply chain problems. Last October the companies tried to negotiate with the state for higher rates for selling renewable energy credits. Their request was turned down, only for the state to open the floor to new project proposals, including from BP and Equinor. “The agreement is the latest evidence of the malaise engulfing the fledgling offshore US wind industry,” writes Myles McCormick at the Financial Times, “but also illustrates the willingness of state authorities to provide flexibility to prevent projects from being abandoned.”

2. Construction goes ahead on SunZia clean energy transmission line

Some important renewable energy news went under the radar this week: Pattern Energy’s SunZia Transmission line secured $11 billion in financing, which means construction can continue on the “largest clean energy infrastructure project in U.S. history.” The 550-mile high-voltage direct current (HVDC) transmission line will run between central New Mexico and south-central Arizona, delivering power to western states from the SunZia Wind facility being built in New Mexico. “The size and scale of both the SunZia project and this multifaceted financing show that the renewable energy space can secure attractive capital at levels previously only seen in traditional generation,” says Daniel Elkort, executive vice president at Pattern Energy.

Upgrading transmission systems will be key to meeting the Biden administration’s goal of eliminating carbon emissions from the power sector by 2035: By one estimate, transmission systems will need to expand by 60% by 2030. The SunZia Transmission line will be able to move 3,000 megawatts of wind power to 3 million people and has been called “bigger than the Hoover Dam.” But its progress has been rocky: Indigenous groups have expressed concerns about the line’s impact on religious and cultural sites, and environmentalists worried it could harm wildlife habitat.

3. New maps show hidden extent of industrial activity at sea

Incredible new maps published in the journal Nature expose the great extent to which human activity has pervaded the world’s oceans. For the project, researchers led by Google-backed nonprofit Global Fishing Watch used artificial intelligence to analyze huge amounts of offshore data from satellite imagery. They found that many industrial vessels aren’t publicly tracked, exposing a potential blindspot for conservation efforts. The data also showed that offshore wind turbines now outnumber oil structures:

4. GOP climate advocate John Curtis launches Senate bid

Utah Rep. John Curtis announced this week he is running for the Senate seat left vacant by retiring Sen. Mitt Romney. The primary field is likely to be crowded, but Curtis’s entry is interesting because he is “one of the GOP’s leading voices on fighting climate change,” says E&E News. He launched and chairs the Conservative Climate Caucus, has supported some of the Biden administration’s policies on solar, and attended COP28 to push for permitting reform. But it will be interesting to see whether climate change features prominently in his campaign: Curtis didn’t mention environmental issues in his first campaign video but pledged to “work to make America not just energy independent, but energy dominant.”

5. Researchers hope volcanic magma could provide ‘quantum leap’ in geothermal energy

Researchers in Iceland have plans to drill into a magma chamber beneath a volcano in an attempt to better understand the hot molten rock and eventually even “make a quantum leap in geothermal energy production,” reports New Scientist. The Krafla Magma Testbed (KMT) project will start drilling in 2026, focusing on a volcano called Krafla in north-east Iceland. The researchers hope to develop near-magma geothermal energy technology that would allow wells to trap hot, pressurized water to drive turbines and produce cheap, clean electricity. “There are endless opportunities,” says Hjalti Páll Ingólfsson at the Geothermal Research Cluster (GEORG) in Reykjavík. “The only thing we need to do is to learn how to tame this monster.”

A company called Moolec Science has been inserting pig genes into soy plants to produce beans that are pink and taste meaty.

Current conditions: A new nor’easter is washing the ocean over North Carolina’s Highway 12 right as crews complete reconstruction on the Outer Banks thoroughfare following last month’s storm • After whipping Mexico’s Pacific Coast with heavy rains, Hurricane Trudy has weakened to a Category 1 storm • Super Typhoon Champi knocked out power for more than half of Guam before barreling toward the Philippines as a potential Category 5 storm.


THE TOP FIVE

1. Wall Street’s AI rout ends for chipmakers, but not for indebted cloud computing giants

Last week was the worst week for the tech-heavy Nasdaq 100 Index since President Donald Trump’s tariffs roiled the market in April 2025. The reason? Hotter than expected federal data on inflation fueled fears of an interest rate hike that could prove devastating to the buildout of artificial intelligence infrastructure. Investors were already worrying the physical investments would cost more than giants such as ChatGPT-maker OpenAI or Claude-creator Anthropic are set to earn. But on Monday, semiconductor makers such as Oracle, Intel, and Micron Technology rallied as the AI rout came to an end. Yet CoreWeave, the cloud-computing heavyweight that led the selloff last week, closed slightly lower. The issue, investors told CNBC, is the company’s debt load. “The market tends to get worried about companies that have refinance risk when rates are higher, and CoreWeave was a little bit of the poster child,” John Lloyd, global head of multi-sector and corporate credit at Janus Henderson, whose firm owns CoreWeave bonds due in 2031, told the broadcaster. “They need the debt markets in order to grow, in some form or fashion.” That CoreWeave came close to bouncing back at all comes down at least in part to Ark Investment Management chief Cathie Wood opting to buy about $12 million of shares in the company amid the market plunge last week, a play for which The Street notes she’s known. Notably, Oracle, which was previously dubbed the “canary in the coal mine” for concern over AI debt, closed just 1% higher before plunging in after-market trading.

Exclusive: Veckta Raises $11 Million to Help Businesses Buy Onsite Solar and Storage

The company simplifies the process of getting consistent, apples-to-apples bids.

With commercial electricity prices steadily climbing, many businesses and real estate owners are increasingly eager to generate and store their own power onsite, cutting their bills and making costs more predictable. But figuring out whether solar and storage can actually pencil out — and under what conditions — can be a nightmare. Ask a handful of developers for a quote and you might get a rooftop solar array from one, a ground-mounted solar and battery system from another, and a gas turbine from a third, each with its own size, price, and financing terms.

That leaves buyers comparing apples to oranges. And for businesses evaluating a portfolio of potential projects, the process gets even messier. “These are very local-centric systems. Different interconnection requirements, different permits, different suppliers,” Gareth Evans, CEO of the onsite energy planning and procurement startup Veckta, told me. “There are hundreds of solar developers in every state.” The hard part, he added, is “knowing what supplier to go with, how to ask them the right questions in the right language, in the right format, so that you’re getting consistent bids back that you can compare and contrast.”
