Direct Utilization of Geothermal Energy 2015 Worldwide Review

Presentation made by John W. Lund and Tonya L. Boyd at the World Geothermal Congress

 Summary of the various categories of direct-use worldwide for the period 1995-2015.

This paper presents a review of the worldwide applications of geothermal energy for direct utilization, and updates the previous survey carried out in 2010. We also compare data from 1995, 2000 and 2005 presented at World Geothermal Congresses in Italy, Japan and Turkey, respectively (WGC95, WGC2000, and WGC2005).

An estimation of the installed thermal power for direct utilization at the end of 2014 is used in this paper and equals 70,329 MWt, almost a 45% increase over the 2010 data, growing at a compound rate of 7.7% annually with a capacity factor of 0.265.
