ISTM a generator, even if it were set up to use induction, first would need to generate a small current using permanent magnets to "jump-start" the process. Without magnets, if no current is flowing, no magnetic field is created, and no power is generated.

Industrial wind turbines just use power from the grid to start up.

Correct, and you could also use a battery to start up.

It was not a great reference to clarify matters, its promotional language, but they state "Vestas’ current turbine range does not use rare earth elements in the generator. "
