AB - Geological complexity of the territory of Serbia is a world curiosity: six  main geo-tectonic regions and tens sub-regions are delineated in a small area  of 88,000 km2. Geologic origin and regional structure of some areas has long  been the subject of discussion. Notable magmatism and associated tectonic  events in the Earth's crust provided for a fairly large hydrogeothermal  resource potential, which is manifested in more than 250 warm (mainly  mineral) springs and more than 100 hydrothermal wells. Thermal springs and  wells together discharge some 5 m3/s. This potential is used in part for  balneal therapy (waters differ in temperature and chemical composition) in  the spa areas of Serbia. The amounts of thermal water unused therapeutically  or the amounts of heat energy from unused geo-thermal water may be used in  almost all spas for space heating/cooling and thus increase the efficiency of  the thermal water energy utilization. This also will be cost-effective,  reduce emission of noxious gases, and improve the environmental-health image  of the resorts. The hydrogeothermal resources are described for 29 spas with  700 l/s total discharge capacity of water temperature between 25°C and 96ºC,  or an overall heat energy of 78.40 MWt. Feasibility of additional energy  utilization of thermal water in spas is generally considered.
