Ms. Alenka Loose from the City of Ljubljana and Ms. Andrea Kinsperger from the City of Vienna presented plans for the development of geothermal energy in their respective cities. Ljubljana looks for a sustainable use of groundwater for both geothermal and drinking water. Vienna promotes shallow geothermal energy through online maps of potential, technical guidelines, subsidies and demo sites, and above-all communication to a wide audience.

Dr. Kai Zosseder from the Technical University of Munich presented a map of thermal groundwater potential developed for the city of Munich, including thorough estimations of aquifer thickness, permeability and temperature. He emphasized that key stakeholders are energy municipal services and not only groundwater and environment administrations. Improving the spatial estimation of cooling needs allows demonstrating the full potential of shallow geothermal energy. Energy services need tools to compare the technical and environmental performances of renewable energies, given local social and regulation constraints. Roberto Vaccaro from EURAC, Bolzano, presented such a tool development planned in the GRETA project, and its implementation on three pilot areas of the Alpine Space. Andreas Kress from Climate Alliance presented how the PEACE_Alps project helps both mayors and municipal staff reaching the targets of their Sustainable Energy Action. Dr. Burkhard Sanner closed the session with an overview of geothermal use in Europe at national levels.
