This map shows enhanced geothermal systems (EGS) Potential at a depth of 4.5km (2.8 miles or 14,800 feet). According to Google.org, EGS produces heat and electricity by harnessing the energy from hot rock deep below the earth's surface, expanding the potential of traditional geothermal energy by orders of magnitude. See http://www.google.org/egs/ for more information.
