Geothermal potential discovered in Minnesota

Researchers at the Natural Resources Research Institute and University of North Dakota discovered that western and central Minnesota contain a much greater supply of potential geothermal energy than originally thought. Temperature readings from 100 existing mining exploration holes and 795 deep water wells showed that shallower, less expensive drilling could produce results in generating renewable electricity. One of the lead researchers expects utilities will consider geothermal as a future energy option. Read the geothermal potential story in the Duluth News Tribune. (registration may be required)
