| Abstract | Geological setting of the Slovak Republic is favourable for occurrence of geothermal energy resources. Twenty-six geothermal areas or structures, covering 27 % of the Slovak territory, have been identified as prospective areas for occurrence of potentially exploitable geothermal resources. Geothermal waters are largely bounded to Triassic dolomites and limestones of the Krizna and Choc nappes, less frequently to Neogene sands, sandstones, conglomerates, andesites and related pyroclastics. Temperature at a depth of 1000 m varies from 20 to 74 ?C with the average value of 45 ?C. The average value of the heat flow density is 82.1 mW/m2 ± 20.5 mW/m2, with the minimum value of 40.6 and maximum value of 121.6 mW/m2. The total amount of thermal-energy potential of geothermal waters in prospective areas (proven, predicted and probable) represents 5538 MWt. Geothermal wells verified 4.5 % of the total thermal-energy potential of the geothermal sources in the Slovak Republic, but only 2.3 % of the potential are utilised. What the proven thermal-energy potential is concerned, only 53 % of it is utilised at present. |
