Primer on geothermal energy

摘要

Alameda Power & Telecom has first- hand experience with geothermal energy. For the past 20 years, our municipal utility, a department of the City of Alameda, Calif., has used this clean, renewable resource to generate electric power for our customers. Today, more than 80 percent of our electric power is generated using renewable energy sources―more than 50 percent of which is geothermal. As one of the 14 members of the Northern California Power Agency (NCPA), Alameda Power & Telecom is part owner of the geothermal power plants from which we derive this renewable energy. The NCPA geothermal facility (see photo), which started generating electricity in 1982, uses steam from The Geysers in Northern California, which is the world's largest geothermal field.
