Maybe they ought to be using Vertical wind mills!
While they can look better, vertical wind mills are less efficient because half the time a wing is being pushed into the wind, using rather than collecting energy. Extremely large/slower moving two blade designs may be the best way to go, but their foundations require enough concrete to build a small nuclear plant. The manufacture of concrete emits huge amounts of CO2. I'm still scratching my head why we should address climate change by removing large amounts of energy from the wind which causes more man-made climate change than a coal plant.
