Yes. The big secret is they're hybrid windmills ;) The grain mills are separated from the wind turbines by electrical lines, unlike their mechanically-linked Dutch grain mill predecessors. Any excess electricity goes into BitFlour, a cryptocurrency that's "milled" instead of "mined".

(For those who missed it, the parent is asserting that "windmill" should be reserved for wind-powered mills.)

Charles Babbage called his Analytical Engine's ALU its "mill". I prefer his term.

In the case of wind turbines, it is clear that the generation unit is its mill, so I have no quarrel with calling them windmills.

They may be considered only half-satanic, having only three blades.
