Trump officials halt offshore wind-farm projects over ‘national security risks’

The Trump administration has said it is immediately pausing all leases for offshore wind farms already under construction, in the heaviest blow yet to an industry that the administration has relentlessly targeted throughout the year.

Trump’s Department of the Interior said that it was halting the building of five wind projects due to “national security risks”. The department said it would work with the US Department of Defense to mitigate the risk of the wind turbine towers creating radar interference called “clutter” that could in some way hamper the US military.

“The prime duty of the United States government is to protect the American people,” said Doug Burgum, secretary of the interior. “Today’s action addresses emerging national security risks, including the rapid evolution of the relevant adversary technologies, and the vulnerabilities created by large-scale offshore wind projects with proximity near our east coast population centers.”

The halt will affect the Vineyard Wind 1 project off the coast of Massachusetts, Sunrise Wind and Empire Wind in New York, Revolution Wind off Rhode Island and Coastal Virginia Offshore Wind in Virginia.

All of the projects were reviewed and approved under Joe Biden’s administration, which found there were no undue national security concerns raised by the developments. Democrats have pointed to two assessments by the Pentagon of Revolution Wind that found the project “would not have adverse impacts to DoD missions in the area”.

Wind developers and regional grid operators have warned that Trump’s attack upon offshore wind will cost billions of dollars in investment, thousands of jobs, and a new supply of clean electricity that will help prop up grids facing heightened new power demand from the rapid advance of artificial intelligence.

Earlier this month, a federal judge in Massachusetts ruled that a Trump order to ban wind project permits was “arbitrary and capricious and contrary to law”. The judge struck down the order following a legal case brought by 17 states and Washington DC.

However, in halting the under-construction wind farms, Trump has escalated his battle against a beleaguered wind industry that he has long reviled since he objected to the sight of wind turbines from his Scottish golf course more than a decade ago.

“Wind is the worst,” the president said at a Pennsylvania rally on 9 December. “That’s a scam. They ruin your valleys. They ruin your peaks. And [it’s] the most expensive energy.”

In fact, wind is among the cheapest energy sources, with costs falling sharply in recent years. Clean-energy advocates had hoped for a late blossoming for offshore wind in the US, which has lagged several countries in Europe, but this has been hampered by animosity from the Trump administration as well as some local opposition.

“For nearly a year, the Trump administration has recklessly obstructed the build-out of clean, affordable power for millions of Americans, just as the country’s need for electricity is surging,” said Ted Kelly, lead counsel at Environmental Defense Fund.

“We should not be kneecapping America’s largest source of renewable power, especially when we need more cheap, homegrown electricity. Instead, this administration has baselessly attacked wind energy with delays, freezes and cancellations, while propping up aging, expensive coal plants that barely work and pollute our air.”
