About 50% of the energy demand in Europe is for heat, so geothermal options have concentrated on district heating. Good district heating hydrothermal developments have utilised the Bavarian Molasse Basin in Germany, the Paris Basin, the Pannonian Basin in Hungary, and the Rhine Graben.
As shown in the map below, Iceland, Italy, and Turkey have higher enthalpy Geothermal Energy due to their favourable geological locations (tectonic plate boundaries).
Other locations are being investigated with modern drilling and power generation technologies.
