The United States is falling behind the European Union in the rollout of wind power and risks being overtaken by China, a think tank said Thursday, days after Trump announced a crackdown on new wind projects.

In a sweeping order, President Trump halted federal approvals for new wind farms, in a move that could affect projects on land and in the ocean.

Trump has claimed to be an expert on “windmills.” (It’s worth noting that windmill is an outdated term that originally referred to centuries-old tech that used wind power to turn stones to grind up grain; the modern tech designed for producing electricity is a wind turbine.)
