Wind Power Pioneers Warn of Mounting Pushback as Trump Moves Against U.S. Offshore Projects

Two architects of the modern wind industry are cautioning that U.S. President Donald Trump’s renewed opposition to clean power signals a wider political shift that could slow the global transition from fossil fuels. Danish engineer Henrik Stiesdal and British physicist Andrew Garrad, both recognized for groundbreaking work on turbine technology, said recent U.S. policy reversals are reverberating across renewable-energy markets.

The pair, frequently dubbed “godfathers of wind” for shaping the sector’s early engineering standards, spoke in London on Nov. 5, 2025, shortly before receiving the 2024 Queen Elizabeth Prize for Engineering from King Charles III. While neither questioned the commercial viability of wind power, they warned that political headwinds are intensifying in the United States and other advanced economies.

Trump, who returned to the White House in January, has issued stop-work orders on high-profile offshore wind facilities and eliminated tax incentives created under former President Joe Biden’s Inflation Reduction Act. At the United Nations General Assembly on Sept. 23 he labeled offshore turbines “pathetic” and “expensive,” adding that climate change is “the greatest con job ever perpetrated on the world.” Those remarks drew criticism from climate scientists, who cite mounting evidence of record heat waves, floods and hurricanes.

“We are facing a change of mood,” Garrad said, calling the U.S. stance “symptomatic” of broader skepticism toward renewable technologies. Stiesdal, while declining to comment directly on Trump, noted what he sees as a “fundamental misunderstanding” among voters who benefit from low-cost green power yet support parties opposed to clean-energy expansion.

Economic fallout for developers

The administration’s actions have already rippled through corporate balance sheets. Danish utility Ørsted, the world’s largest offshore-wind developer, reported a net loss of 1.7 billion Danish kroner (US$261.8 million) for the July–September quarter, swinging from a 5.17 billion-krone profit a year earlier. Company shares, down more than 80 percent from a 2021 high, touched a new record low in August after Washington halted construction of a nearly completed U.S. project.

Turbine manufacturer Vestas is also navigating policy uncertainty. Chief Executive Henrik Andersen told CNBC on Nov. 5 that the firm maintains a “well-established” U.S. supply chain but acknowledged that “not everyone likes the nature of a wind turbine.” He added that energy prices ultimately drive investment decisions.

The financial strain illustrates how political signals can upend business models predicated on multi-decade cost-recovery timelines. Both Garrad and Stiesdal argued that uncertainty raises capital costs and slows deployment at a moment when many nations are racing to meet emissions-reduction targets outlined in the Intergovernmental Panel on Climate Change reports.

Technical legacy and policy risk

Stiesdal drafted key design principles for early turbines and oversaw the world’s first commercial offshore wind farm, installed off Denmark’s coast in 1991. Garrad pioneered computer models now widely used to certify turbine safety and optimize farm layouts. Their technical advances helped drive down offshore wind costs by roughly 60 percent over the past decade, according to industry data.

They now fear that political setbacks could erode those gains. “This isn’t just a wind-energy problem,” Garrad said. “To reverse course on a transition of this scale is dangerous because it shows how political decisions, rather than economics or engineering, can dominate.” Stiesdal highlighted energy security and local job creation as benefits that rarely feature in partisan debates yet resonate with communities hosting renewable projects.

Opposition remains concentrated in developed nations, the engineers said, while emerging economies continue to add wind and solar capacity to reduce reliance on imported fuels. Still, they urged policymakers in Europe and North America to provide stable frameworks that protect long-term investments.

As the two industry veterans accepted their engineering prize at St. James’s Palace, they emphasized that hard-won progress over four decades could be stalled if governments retreat from climate commitments. Whether Trump’s strategy gathers momentum elsewhere, or triggers a counter-mobilization in favor of renewables, may determine how quickly the world shifts toward low-carbon power in the critical years ahead.
