Windmills are an option for electricity and in the past for machinery. This is a place to discuss any pros or cons along with any brands. I have heard it said that they only work in a wind tunnel. I happen to live in a wind tunnel. A power transmission line runs through my property and the trees are kept cut down to prevent problems. The area I live in is known for its wind. Wind zones are rated up to a scale of 7. My last home was in an area rated 6.5 to 7 depending on who did the rating. I do believe that windmills are a viable option.
