Five hot, rockin’ geothermal companies:

Cross-posted from Climate Progress . Like the natural gas sector, which has experienced an incredible boom due to new drilling techniques that allow companies to cost-effectively access unconventional gas, the geothermal sector is going through a renaissance that may open up a vast new set of resources. Traditional utility-scale geothermal, often called hydrothermal, utilizes hot water or direct steam beneath the earth to run a turbine and generate electricity. While there's only about 11 gigawatts of capacity built around the world (the solar photovoltaic industry built 17 gigawatts in 2010 alone), the actual electricity generation from these baseload plants typically doubles the output from an equivalent wind or solar project. The U.S. Geological Survey estimates that there are about 35 gigawatts of hydrothermal resources left to harness in America with the potential to ...
