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.”

    THE KICKER

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

    Zanskar Raises $115 Million to Propel Geothermal Discoveries

    One of the buzziest climate tech companies in our Insiders Survey is pushing past the “missing middle.”

    One of the buzziest climate tech companies of the past year is proving that a mature, hitherto moribund technology — conventional geothermal — still has untapped potential. After a breakthrough year of major discoveries, Zanskar has raised a $115 million Series C round to propel what’s set to be an investment-heavy 2026, as the startup plans to break ground on multiple geothermal power plants in the Western U.S.

    “With this funding, we have a six power plant execution plan ahead of us in the next three, four years,” Diego D’Sola, Zanskar’s head of finance, told me. This, he estimates, will generate over $100 million of revenue by the end of the decade, and “unlock a multi-gigawatt pipeline behind that.”

    1. New Jersey’s new governor freezes electricity prices during inauguration speech

    Mikie Sherrill wasted no time in fulfilling the key pledge that animated her campaign for governor of New Jersey. At her inauguration Tuesday, the Democrat signed a series of executive orders aimed at constraining electricity bills and expanding energy production in the state. One order authorized state utility regulators to freeze rate hikes. Another directed the New Jersey Board of Public Utilities “to open solicitations for new solar and storage power generation, to modernize gas and nuclear generation so we can lower utility costs over the long term.” Now, as Heatmap’s Matthew Zeitlin put it, “all that’s left is the follow-through,” which could prove “trickier than it sounds” due to “strict deadlines to claim tax credits for renewable energy development looming.”

    Why America’s Climate Emissions Surged in 2025

    Rob talks through Rhodium Groups’s latest emissions report with climate and energy director Ben King.

    America’s estimated greenhouse gas emissions rose by 2.4% last year — which is a big deal since they had been steady or falling in 2023 and 2024. More ominously, U.S. emissions grew faster than our gross domestic product last year, suggesting that the economy got less efficient from a climate pollution perspective.

    Is this Trump’s fault? The AI boom’s? Or was it a weird fluke? In this week’s Shift Key episode, Rob talks to Ben King, a climate and energy director at the Rhodium Group, about why U.S. emissions grew and what it says about the underlying structure of the American economy. They talk about the power grid, the natural gas system, and whether industry is going to overtake other emissions drivers as once thought.
