The Geothermal Resources Council (GRC) has announced the outstanding technical presentations from the global geothermal energy community for 2017.
The selections were made in each of the GRC Technical Sessions held in early October at the 41st GRC Annual Meeting in Salt Lake City, Utah, USA, the world’s largest annual geothermal energy event. The judging criteria included the technical content, the quality of the visual aids and the presenter’s ability to communicate the subject matter. Over 220 presentations were made totaling over 75 hours over three days. More than 1,000 attendees came to the GRC Annual Meeting and GEA GeoExpo+ from 35 different countries around the world.
