This was a heated topic for many who live near Nantucket off the coast of Massachussetts and the mariners who ply the local waters.  It had been suggested that a wind farm be built with some astronomical number of units (1000?) located about 20 miles off shore. 

It was similar to the heated discussions about fish farms.

I have heard it said, but cannot substantiate it, that an on-shore 
installation will have an overall energy payback time of 3 years in a 
suitably exposed position. I suspect an offshore installation will be 
somewhat longer. However, in the UK, a wind farm will work at ~14 - 18% 
of its rated capacity; where you and I live, somewhat less at <10%.
