Tehachapi Mountains, California
Located in the Tehachapi Mountains of California, the Alta Wind Energy Center is the largest wind farm in the US, and third largest onshore farm in the world. The facility plans to reduce carbon dioxide emission by more then 5.2 million metric tons over the next 25 years, which is roughly the same as eliminating 446,000 cars off the road.
