The Week in Sustainable Energy Stocks (Week Ending 3/7)

We track 13 geothermal stocks including all the names you mentioned. We include Calpine in the geothermal search but we don't consider it to be a sustainable energy company - the last time I looked it had 25,000 MW of gas fired combined cycle generation and about 1,000 MW of geothermal. Two of the companies, Ormat and Geodynamics, are included in our Renewable Electricity index.
