The U.S. Department of Energy Geothermal Technologies Program (GTP) seeks input to support The U.S. Geological Survey and U.S. DOE initiative to update geothermal resource classification. In support of DOE Geothermal Technologies Program (GTP) goal of increasing the installed geothermal capacity in the United States, the U.S. Geological Survey is collaborating with the GTP on expanding geothermal resource assessments, developing new geothermal resource classification standards and assisting in the establishment of the National Geothermal Data System. The results of this work will enable lower risk/cost deployment of demonstrated, clean, renewable, baseload conventional and Enhanced Geothermal Systems (EGS) geothermal power as it will provide the data and assessments necessary to stimulate public interest, market acceptance, and in turn the growth of the geothermal industry.
