                            Slovenia is relatively rich in thermal 
                              water springs. Twenty one natural thermal springs 
                              are known with temperature close to or above 20 
                              °C, however, there are several drilled localities 
                              where no surface thermal manifestations existed. 
                              Details about the geothermal field of Slovenia as 
                              well as geotectonic background can be found in Ravnik 
                              (1991), Ravnik et al. (1992) and Ravnik et al. (1995).

                              and geophysical research as well as the methods 
                              used for determination of geothermal resources are 
                              briefly described in Rajver et al. (1995) and Ravnik 
                              et al. (1995). Information about the present direct

                              in northeastern Slovenia is given in Kralj (1996,

                            Geothermal energy is estimated to 
                              currently supply approximately 703 TJ/yr of heat 
                              energy through direct heat applications in Slovenia.
