IEA - Activities & Achievements

General GIA Activities

The activities of the GIA support and advance the development of geothermal energy in numerous ways. The GIA Executive Committee holds two meetings each year to report on national programmes, share information and results of work conducted in the annexes, consider ongoing issues, and plan future activities. The GIA Secretariat assists the Executive Committee with the production of a comprehensive annual report, the writing of informative documents and of papers for international publication and presentation, and the operation and maintenance of a GIA webpage for worldwide information dissemination. In addition, the results of our annex work are presented in reports, at international conferences and in international journals.

Joint IEA-GIA~IPGT EGS Induced Seismicity Efforts

Induced seismicity is one of the most important geothermal issues currently being investigated, especially in association with the development of Enhanced Geothermal Systems (EGS). GIA Annex XI (Induced Seismicity) and IPGT Working Group 7 (Induced Seismicity) are combining their efforts to address crucial issues associated with this topic.

GIA~IPGT Meeting, 3 May 2011, Paris, France

The GIA and IPGT held a joint meeting in Paris, France, on 3 May 2011, to begin defining and coordinating joint efforts on induced seismicity associated with EGS development and operation. Meeting agenda, presentations and agreed tasks are available:

Proceedings and Presentations from the

Joint GIA-IGA Workshop-

Geothermal Energy- Its Global Development Potential and Contribution to the Mitigation of Climate Change

A 2-day joint GIA-IGA workshop was held in Madrid, Spain, on 5-6 May 2009, to discuss the global potential of geothermal energy and its possible contribution to the mitigation of climate change. The results provided input to the geothermal chapter of the IPCC Special Report on Renewable energy and Climate Change to be published in 2010. Copies of the workshop proceedings and presentations are available below. Please direct any questions to: GIA Secretary
