I’m a tree-hugger from way back. When I was a girl, my folks sent us to a wonderful new school (Upland Hills School and their Ecological Awareness Center) where we learned about things like solar power and wind energy . Power for the school came from a wind generator and solar panels. This was in the early ‘70s, long before regular folks like us ever thought about photovoltaic panels and wind turbines.
