Who says wind power isn't efficient? Enercon, Germany's largest wind turbine manufacturer, has just unveiled the E112, the most powerful turbine in the world. With a span of a whopping 367 feet, this monster can power 4,000 homes at once.

4,000 homes?! That's seriously impressive. I know that people don't want to look out their windows and see a bunch of gigantic windmills, but it seems better than looking out your window and not being able to see very far because of the smog caused by coal-powered plants. Why aren't we seeing more use of wind power here in the States?
