Munich sits on a massive geothermal aquifer system (the Molasse Basin) "Medium-deep geothermal resources in the Molasse Basin: A geological, techno-economic, and ecological study of large-scale heat pump integration" https://www.sciencedirect.com/science/article/pii/S0960148125008092 https://www.sciencedirect.com/science/article/pii/S096014812... Tapping a geothermal aquifer system is much easier than to get useful quantities of heat from dry rock, because in most places the thermal conductivity of rock is very low. "The enthusiasm in the research community is justified by the vast extent of the energy supply and the low environmental impact of the method, however significant breakthroughs will be required to make this a commercial energy resource." https://en.wikipedia.org/wiki/Hot_dry_rock_geothermal_energy https://en.wikipedia.org/wiki/Hot_dry_rock_geothermal_energy
