The German Geothermal Association (BVG) pools companies as well as individual members working in research and application of geothermal energy. Founded in 1991, the Berlin-based association represents a variety of members from industry, science, planning and energy sectors. The association's main goal is to inform the public about the possible uses of geothermal energy and promoting dialogue with politicians and political leaders. The BVG hosts an annual conference, as well as other regular events. It publishes the journal “Geothermische Energie” and further information material.
