The Future of Geothermal Energy
The Future of Geothermal Energy report is an evaluation of geothermal energy as a major supplier of energy in the United States. An 18-member assessment panel with broad experience and expertise was formed to conduct the study beginning in September 2005. The work evaluated three major areas of Enhanced Geothermal Systems (EGS):
- Magnitude and distribution of the EGS resource
- Status and remaining requirements of EGS technology needed to demonstrate feasibility at a commercialscale
- Economic projections of impact of EGS on U.S. energy supply to 2050
The report evaluates the status of EGS technology, details lessons learned, and prioritizes R&D needs for EGS. It will inform the ongoing debate of how to provide a more sustainable and secure energy supply for Americans for the long term, without compromising our economic capacity and political and social stability, and while minimizing environmental impacts. Therefore, energy researchers and developers, utility analysts and executives, and government policy makers should find our report useful. The panel's report was issued in January 2007.
