Wind Energy

I recently attended the annual Farm Aid concert which was in Camden, NJ this year. At the concert Silk(R), which is a company that makes soy milk, was handing out information on wind energy. Using windmills for power is not a new idea and is probably the most efficient and clean source of energy. If we were to switch our power plants to run on wind energy we would have a much more clean environment and our energy costs would be a lot lower. The amount of energy you get from a windmill in one year is what you get from a typical polluting power plant in four years. Wind mills are four times more efficient than what we are using now, I don't understand why anyone wouldn't want to have a cleaner environment and save money at the same time.
