Best Geothermal Energy presentations of 2015 announced

The Geothermal Resources Council (GRC) has announced the outstanding technical presentations from the global geothermal community for 2015.

The selections were made in each of the GRC Technical Sessions held in late September at the 39th GRC Annual Meeting in Reno, Nevada, 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 135 presentations were made totaling over 45 hours over three days. More than 1,200 attendees came to the GRC Annual Meeting and GEA Expo from around the world.
