How does an induction motor generate kW when there is only load and no prime mover?

[Sahib]

I'm pretty sure this thread is a spin off from an off topic comment in another thread.

So how does an induction motor generate power that it did not already put into the load without a prime mover acting on that load, and how is wind driving a propeller not a prime mover in such an application?

Bugnan1400's joke consisted in his pointing out figuratively that, though Phil's comment of increased KW of induction motor referred to its mechanical output measured in KW and not electrical output in KW, he failed to mention it!
