found 3tiergroup who have a cool web product that maps all solar, wind and hydro resources with google maps integration. type in your address and see what your average wind speed is, or check the solar data. the company hopes to make money selling this data to commercial project developers, but it is a fun thing to do for your house. They add in things like incentives to give you a “score” which is pretty unique.
