A method for converting geothermal energy, wherein at least one geothermal probe, which is arranged in the ground up to a maximum depth of 50 m, transfers heat energy from the ground to a liquid medium, this energy is transferred from the liquid medium to a liquid heat transfer medium, this energy is transferred from the liquid heat transfer medium to a refrigerant flowing in the opposite direction, wherein the refrigerant is transformed into a gaseous state, the energy of the refrigerant is subsequently converted into a rotational movement, and the energy of the rotational movement is converted into electrical energy by means of a generator, wherein the method can be operated continuously, the energy of the refrigerant is converted into a rotational movement in a gas pressure motor, wherein the gaseous refrigerant is continuously applied to the gas pressure motor, the generator is an alternating current generator, at least the refrigerant is conducted in a closed circuit, and the refrigerant is ammonia, wherein the geothermal probe is such that it comprises at least one main probe which comprises at least: - an evaporation chamber, which consists of at least one refrigerant chamber of a counterflow evaporator (1.2; 1.2,1; 1.2.2) and is arranged in the closed refrigerant circuit, - a riser pipe, which is connected to the lower end of the evaporation chamber (2.1), - a supply line, which is connected to the evaporation chamber and is arranged in the refrigerant circuit, - a heat exchanger chamber (2.3), which consists of at least one heat transfer medium chamber of the counterflow evaporator (1.2; 1.2.1; 1.2.2) and is arranged in a main probe heat transfer medium circuit of the heat transfer medium, and a supply probe, which at least comprises: - an outer casing, the outer side of which is surrounded by the ground, - an intermediate space in the probe, which is delimited at least partially by an inner side of the outer casing and a probe base, in which the main probe is arranged, and at least one inlet for the liquid heat transfer medium, which is arranged in at least one open supply probe heat transfer medium circuit of the heat transfer medium. - an evaporation chamber, which consists of at least one refrigerant chamber of a counterflow evaporator (1.2; 1.2,1; 1.2.2) and is arranged in the closed refrigerant circuit, - a riser pipe, which is connected to the lower end of the evaporation chamber (2.1), - a supply line, which is connected to the evaporation chamber and is arranged in the refrigerant circuit, - a heat exchanger chamber (2.3), which consists of at least one heat transfer medium chamber of the counterflow evaporator (1.2; 1.2.1; 1.2.2) and is arranged in a main probe heat transfer medium circuit of the heat transfer medium, and a supply probe, which at least comprises: - an outer casing, the outer side of which is surrounded by the ground, - an intermediate space in the probe, which is delimited at least partially by an inner side of the outer casing and a probe base, in which the main probe is arranged, and at least one inlet for the liquid heat transfer medium, which is arranged in at least one open supply probe heat transfer medium circuit of the heat transfer medium.
