I came across a town with lots of turbine windmills. I started to wonder if turbine wind farms will replacing the old fashion wind mill? Who knows! Windmills helped settle farming communities around the world in general; by pumping water up from depths. Now we use turbines to manufacture electric. This helps by driving down the cost of electric for local towns and outer line areas. I believe there is a need for both kinds. (This is my observation an opinion about this subject)
