How a Geothermal Power Plant WorksTake a geothermal energy field trip—from the depths of the Earth through the turbine of a modern geothermal electric generation power plant—on your computer. You can access this virtual tour from the Geothermal Resources Council Web site. |
Enhanced Geothermal SystemsEnhanced geothermal systems (EGS) offer great potential for dramatically expanding the use of geothermal energy. Present geothermal power generation comes from existing hydrothermal reservoirs, which are limited in location to areas in the western U.S. EGS offers the chance to extend use of geothermal resources to new geographic areas of the entire U.S. More than 100,000 MWe of economically viable capacity may be available in the continental United States, representing a 40-fold increase over present geothermal power generating capacity. This potential is about 10% of the overall U.S. electric capacity today, and represents a domestic energy source that is clean, reliable, and proven.
