If you can attach an EV engine to a windimill.
It will produce a lot of free electricity. (For the same reasons regenerative braking is a thing)
The 147 horsepower leaf electric engine can produce 110,250 watts of electricity as an alternator/generator. 110 kilowatts. (750 watts in 1 horsepower. Times 147 HP.)
The catch is most electric engines have to spin at high RPM to generate peak power. This can require a 1:50 to 1:100 gearbox. Which can be difficult to come by.
And to generate that much power, the windmill would be big. That could be easier with VAWT that spins on a vertical axis.
That is one use for EVs if the battery pack is too expensive to replace.
I would guess people hate windmills though.
