Direct use of geothermal resources covers the range of from about 65°F to 270°F. If one excludes aquaculture, spas and pools which can utilize the lowest temperatures, actual uses range from 99°F used to heat a church in Idaho to 270°F utilized for vegetable dehydration in Nevada. Most of the current uses are for space and domestic water heating; but, the potential for increased industrial processes is fairly large if fossil fuel prices remain high
