An MIT-led study of the potential for geothermal energy within the United States published in 2007 found that Enhanced Geothermal System (EGS) technology could supply a substantial portion of US electricity well into the future, probably at competitive prices and with minimal environmental impact. Overall, the panel concluded that EGS can likely deliver cumulative capacity of more than 100,000 MWe within 50 years with a modest, multiyear federal investment for RD&D. The panel estimated the total EGS resource base to be more than 13 million exajoules (EJ), with an estimated extractable portion to exceed 200,000 EJ—about 2,000 times the annual consumption of primary energy in the United States in 2005.
