The International Geothermal Association (IGA), founded in 1988, is a scientific, educational and cultural organization established to operate worldwide. It has more than 5,000 members in over 65 countries. The IGA is a non-political, non-profit, non-governmental organization with consultative status to the UN.
The objectives of the IGA are to encourage research, the development and utilization of geothermal resources worldwide through the publication of scientific and technical information among the geothermal specialists, the business community, governmental representatives, UN organisations, civil society and the general public.
One of IGA's aims, as defined in the Charter of the Association, is to encourage, facilitate and, when appropriate, promote the coordination of activities related to worldwide research, development and application of geothermal resources. The IGA headquarters is located in Bochum, Germany at the International Geothermal Centre of the Bochum University of Applied Sciences.
The IGA is a founding partner of the International Renewable Energy Alliance (REN Alliance). The REN Alliance is a close partnership of five globally operating renewable energy associations with the aim of promoting renewable energy sources worldwide.
The work includes political dialogue and advisory on potentials and scenarios for renewables, sustainability assessments, carbon funds, policies and other related fields.
The other REN Alliance partners are the International Hydropower Association (IHA), the International Solar Energy Society (ISES), the World Bioenergy Association (WBA) and the World Wind Energy Association (WWEA).
