Orsted A/S shares fell as much as 19% to hit a record low after the Trump administration blocked construction of an almost-finished offshore wind farm, throwing a wrench into the Danish company’s planned $9.

There is no evidence that wind farms cause cancer. As recently as last year, the federal government declared there was no known link between large-scale whale deaths and offshore wind. Turbine blades whipping through the air do kill birds, as do buildings with glass facades. As for the aesthetic merits of turbines, it’s a matter of debate.
