I believe the answer is:

wind farm


I'm afraid I can't even guess how this answer relates to the clue.

(Other definitions for wind farm that I've seen before include "Group of aerial rotors generating electricity" , "Generating station" , "source of energy" , "Alternative plant for generating electricity" , "this should give you plenty of energy" .)

I've seen this clue in The Guardian.
