Best Geothermal Energy Presentations of 2016 Announced

The Geothermal Resources Council (GRC) has announced the outstanding technical presentations from the global geothermal energy community for 2016.

The selections were made in each of the GRC Technical Sessions held in late September at the 40th GRC Annual Meeting in Sacramento, California, 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 115 presentations were made totaling over 40 hours over three days. More than 1,250 attendees came to the GRC Annual Meeting and GEA GeoExpo+ from around the world.
