Makes no sense because most modern turbines can “feather” their blades so they are at a 90 degree angle to the wind and they stop turning. Did the writer do any research at all?
They can also disconnect the turbines from the grid and lock the blades in place.
As for batteries. There aren’t enough in the world. The large turbines can produce 1.5 to 5 million megawatts an hour each at peak production.

True. I like
the kind of turbine (10-foot rotor, honest 700 watts in a good wind) that furls in higher winds and even magnetically slows as less current is required from the battery (see Midnite Classic MPPT controller and Clipper for turbines). Building it requires a little steelwork and mechanical experience/study, though, neither of which are enjoyed by government-dependent commie-NIMBYs.
(17-footer, honest 3kw in a good wind). ...2-3 times the power with the Classic controller and Clipper.

Engineer’s comments on the Classic MPPT controller for wind turbines with the Otherpower 10-footer (username: halfcrazy, first MPPT controller for both wind turbines and PV arrays).

The Classic has been further engineered since then and is available. [I receive no pecuniary benefits from any vendor in the wind industry. ...only the money that I save for myself in a very windy and sunny place with extreme cold weather. I do all installation work for myself and receive no subsidies. ...not even wealthy enough to qualify for any subsidies and not installing expensive, wasteful, commercial versions of components in order to qualify.]
