Renewable energy in today's world is referred to as a clean and accessible energy source. Renewable energy sources include shallow geothermal energy, which in Slovenia has great potential for heating as well as for cooling facilities. This energy is stored in the Earth's interior in the form of heat, where it is used through wells to carry heat up to a depth of 300m. Thermal energy utilization is divided into two geothermal thermal systems, closed and open geothermal systems. Closed geothermal thermal systems are the most widely used in Slovenia, where heat is extracted by the so-called geos probe, which does not come into contact with the Earth's hill due to the closed system and thus minimally affects the hydraulic and thermal influences of the Earth's interior. The system operates with the help of a heat pump that takes care of space heating.
The first part presents the basics of geothermal energy, as well as shallow geothermal energy and its own potential. The purpose is to present shallow geothermal energy and its exploitation, and to demonstrate the ecological impact on the environment. There is also described which Slovenian territories has the most potential for using shallow geothermal energy. In Slovenia shallow geothermal energy is mostly used for space heating. Important equations for calculating shallow geothermal potential, as well as calculating the heating number and determining the seasonal coefficient of efficiency are also given. Also described are geotechnological parameters and calculations for the implementation of a closed geothermal system with a geos probe used for heating a single-family house.
