Geothermal energy is energy derived from the heat of the earth. In France, ADEME (French Environment and Energy Management Agency) offers a financing program : the geothermal heat fund, to finance geothermal projects. It can be used at the level of :

Buildings (very low energy geothermal energy):

With groundwater or probe heat pumps, the building will be able to use geothermal energy to meet the heat requirements (heating, air conditioning, district heating networks), replacing a fossil solution. Thus, a feasibility study for a building is carried out in order to offer the best cost-effective solution with financial support from the geothermal heat Fund, insofar as the owner uses geothermal energy as a source of energy for heat consumption.
