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.

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 (It’s worth noting that windmill is an outdated term that originally referred to centuries-old tech that used wind power to turn stones to grind up grain; the modern tech designed for producing electricity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.)

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.
