Most of Europe’s geothermal resources are available at a low temperature.
It is necessary to have water associated with the heat source to permit heat transfer to the surface.
Deep drilling is expensive so that the exploitation of geothermal energy is economic only at certain privileged sites where there are geothermal reservoirs at reasonable depths with the additional constraint that there must be a suitable market for the heat.
