The Oregon Department of Geology and Mineral Industries has published a new map showing hot springs, volcanic vents, test wells, and other geothermal resources across the state.
Naturally occurring hot water and steam found mostly in volcanic parts of the West can be used to heat homes and generate electricity.
Clark Niewendorp, a GRC member, who developed the map, says existing geothermal technology requires hot water that’s between 70 and 90 degrees Celsius (or between 158 and 194 degrees Fahrenheit) for commercial power generation.
