The Geothermal Energy Association (GEA), Geothermal Resources Council (GRC) and Geo-Exchange Organization (GEO) have developed a guide specific to the state of California for consideration of geothermal energy development. The guide walks through the benefits and uses of three major types of geothermal applications: power generation, direct use and heat pumps. For more information and to review the guide, visit this interactive feature on Renewable Energy World‘s website.
