GRC Geothermal Library

The GRC has added all the papers associated with the technical session presentations to the GRC Geothermal Library.

The Geothermal Resources Council (GRC) has announced the outstanding technical presentations from the global geothermal community for 2014.

The selections were made in each of the GRC Technical Sessions held in late September/early October at the 38th GRC Annual Meeting in Portland, Oregon, 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. Over 1,400 attendees came to the GRC Annual Meeting and GEA Expo from 39 different countries around the world.
