A federal judge in Massachusetts has struck down an executive order by President Donald Trump that halted offshore wind projects, including the nearly completed Revolution Wind. The order had threatened jobs and regional energy targets. The court ruled the order unlawful, allowing projects to resume.

NextEra Energy is partnering with Meta, Google and Exxon Mobil to add 15 gigawatts of new generating capacity by 2035. The initiative is designed to support artificial intelligence growth. The Meta portion focuses on clean energy and includes 11 power procurement deals for roughly 2.5 GW of solar and battery storage capacity.

Ananym Capital has holds a significant stake in Siemens Energy and is calling on the company to spin off its wind unit, Siemens Gamesa, per The Financial Times. Ananym argues that the wind business is holding back the gas turbine and grid power segments. Siemens Energy has stated that it values constructive input and is executing its plans for the wind business.

Developers have nixed nearly 2,000 power projects in the US this year, representing 266 gigawatts of capacity, reports Cleanview. Most of the cancellations involve clean energy, including 86 GW of solar, 79 GW of energy storage and 54 GW of wind. It attributed the trend to changes in PJM Interconnection's market, policy headwinds and structural challenges. Local opposition is also on the rise, with Cleanview's Michael Thomas noting the sentiment is driving cancellations in growing data center hubs.

The US solar panel market is navigating a complex landscape of tariffs, import rules and the Foreign Entity of Concern rule. This piece has gathered everything leaders need to know into one easy-to-access location with the latest updates, including the status of potential retroactive duties and the ongoing Section 232 investigation into polysilicon.

New Jersey officials have introduced an updated Energy Master Plan that targets 100% clean power by 2035 and significant emissions reductions by 2050. An earlier version of the plan has helped guide the state's clean energy agenda and this new one will usher in the next phase, but it must do so while also dealing with rising demand from data centers. The state plans to increase solar fourfold from 5 gigawatts today to 22 GW by 2050.

Battery prices are expected to decrease by 3% next year to $105 per kilowatt-hour, driven by increased manufacturing capacity in China, competition and a shift to lithium-iron phosphate technology, according to a survey from BloombergNEF. This drop follows an 8% decrease this year despite rising raw material costs. "This is an important moment for the industry, as record-low battery prices create an opportunity to lower EV costs and accelerate the deployment of grid-scale storage to support renewables integration around the world," says BNEF's Evelina Stoikou.

Cornell University is advancing the Earth Source Heat project to heat its campus with geothermal energy by 2035. The initiative involves drilling deep wells to access heat from 2 miles underground, a challenging task in upstate New York's rocky geology. Unlike typical geothermal projects, Earth Source Heat focuses solely on heating, rather than generating electricity. "We can't decarbonize without solving the heat problem," says project manager Wayne Bezner Kerr.

Residential solar installer Posigen filed for Chapter 11 bankruptcy protection in late November after halting most of its operations in August. The company cited liquidity strains from rapid expansion and advancing project costs during a period of market slowdown. The bankruptcy filing aims to provide the company with time to stabilize its finances and complete existing installations under court supervision.
