  1. Tapping the Earth's Natural Energy

    Geothermal power plants take advantage of the earth's hot spots. In and below the earth's crust, radioactive material decays, heating up everything around it. Temperatures can reach 1,200 degrees C producing steam. The steam spins a turbine, which turns the shaft of an electric generator. For hot spots that do not have underground water nearby, engineers can send water through pipes to the hot spot and convert the water to steam. Geothermal energy is most likely to be harnessed in an area close to volcanic activity.

  3. Study Finds Conditions Ripe For Major Quake Along San Andreas Fault

    CALIPATRIA, CA - JULY 03: Steam rises as a geothermal power plant taps into energy produced by underground pressures near the southern end of the San Andreas Fault at the Sonny Bono Salton Sea National Wildlife Refuge on July 3, 2006 near Calipatria, California. The plant is located over the Salton Sea Geothermal Field where temperatures measured in wells drilled for geothermal brines reach 360 degrees Celsius at depths of 1,500 to 2,500 meters. Scientists have warned that the southern end of the 800-mile-long San Andreas fault north and east of Los Angeles has built up immense pressure and could produce a massive earthquake at any time. Such a quake could produce a sudden lateral movement of 23 to 32 feet which would be would be among the largest ever recorded.
