What is the expected energy output of a windmill under these terms?

Tuesday, January 6th, 2009

Jake asked: If a windmill of 330 feet in diameter creates 2 megawatts of energy when the wind is blowing at a constant 20 MPH - should the outcome be proportionality the same if the windmill is smaller? For example: a windmill of 2.5 feet should be expected to create ...
