Fine for motion, but like solar panels, trying to generate electricity 
efficiently becomes an issue. Usually the chemicals required to do so 
are enough to outweigh any environmental savings, and these turbines 
spin faster and are much bigger than mills.
Then there is all that's required to get such a volatile supply of 
electricity onto the national grid.
