The Power of Wind

Long time follower of wind energy, since I was introduced to a system pumping water on a neighbor's farm:

" ... Regional grocer H.E. Butt Grocery Co. has signed on with CPS Energy, San Antonio's municipally owned natural gas and electric company, to use wind energy to help power its 46 stores throughout San Antonio and Bexar County." ... '.

Of course there are likely zoning issues, but wouldn't it be a better marketing idea to place some of these on or next to the at lease some stores? This just designates a portion of power from the grid. Update: And they seem to be moving in that direction.
