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). 
 Geothermal 
investigations and results of hydrogeological 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 use of geothermal energy and some geothermal projects in northeastern Slovenia 
is given in Kralj (1996, 1998, 1999), Kralj et al. (1994) and Vorsic et al. (1995). 
Geothermal energy is estimated to currently supply approximately 
703 TJ/yr of heat energy through direct heat applications in Slovenia.
