One of the highlights of my trip to the midwest last week (see Wildflowers and ART) was a visit to a high school in Union City, Indiana to see their 2.5 MW wind turbine. Generates electricity and provides a wonderful teaching tool for classes on sustainable energy. [NOTE: Clif Bar, Inc. provided a subsidy to build the wind turbine through its carbon offset program.
