Windmills

Upon driving back from Helena, Montana to Seattle, we crossed the Columbia River. I looked up and saw these massive 3 pronged windmills specled over a rolling hill/ small mountain. I have to admit i was more fixated on the windmills and there seemingly huge sturdy white structure , standing out on the mountain, than the massive river flowing under me. It just amazed me that there were these huge structures collecting power from the wind out in the middle of nowhere. But why can't we have these more throughout the U.S. Obviously, it would be a wonderful advancement or rather change from the Taker lifestyle to the Leaver lifestyle. We would conserve energy and be able to harvest it naturally taking the huge amount of power from the wind and use it instead of electrical power. I am a firm believer in using more reliable earthfriendly and completely renewable energy source rather than the wasteful methods for energy used today.
