Claim: "Just look at the wind turbines. None of them are working," said a social media user, posting a video showing wind turbines that aren't turning. "A blot on the landscape and completely inconsistent energy efficiency."

DW Fact check: False Just because wind turbines aren't turning all the time, that doesn't make them inefficient. Modern turbines are highly efficient, with a capacity to convert 30 – 48% (onshore) and 50% (offshore)of the wind's kinetic energy into electricity. According to aerodynamics, Betz's law or the "Betz limit" stipulates that the maximum power that a device can theoretically extract is 59% of the available power.
