NREL’s graph shows USGS estimates of the supply of electricity generation potential from geothermal resources for the U.S. as a whole. GEA’s recent “Report on the State of Geothermal Energy in California” states, “As the technology and techniques to tap hidden or undiscovered geothermal systems improves, the risk of developing these hydrothermal systems declines. As a result, the amount of geothermal resources that can be developed increases, effectively expanding the geothermal supply curve.”
GEA submitted the report to California legislators as part of a joint committee hearing on the potential for geothermal in the state (see full story below). With around 600 MW of planned capacity additions and 1,400 MW total of its potential resources being developed, the state has more potential power under development than any other state, despite Nevada having a greater number of projects. As California stakeholders learn more about the value geothermal power adds to the grid and follow up with legislation that properly considers unique characteristics of different renewable energy sources, Californians can hope this will mean a greater supply of geothermal power.
