The shallow geothermal resource – the heat content of the ground right below our feet– represents an immense and ubiquitous energy source. Nevertheless its tapping and use must be done in a controlled and –ideally– in a regulated manner. In Switzerland the utilization of shallow geothermal resources by ground-coupled heat pumps systems (also termed geothermal heat pumps, GHP) develops at remarkably high speed: Presently there is about one GHP installation every 2 km2. Although it is obvious that some regulation is necessary to avoid an overuse of the resource, so far there are no direct means of control by authorities, except from the view-point of groundwater protection. In this paper the present status of shallow resources utilization in Switzerland is summarized, followed by means and ways to manage the resource in a reasonable way, on the basis of special maps. Renewability and sustainability aspects are also covered.
