"Geothermal" is a term applied to two different kinds of energy. One is energy derived from the internal heat of the Earth. The other is derived from energy that can be pumped out of the earth or water by a heat pump.

Geothermal energy derived from internal energy of the Earth could, in theory, be done anywhere. A limiting factor is the depth of the well that has to be drilled to get to the heat. In some places, such as at hot springs, drilling is not necessary. In others, the well would have to go too deep to be practical.

Geothermal from a natural heat sink with a heat pump is impractical where the local ground and/or water is too cold to be useful. Certainly an ice field or permafrost is not a practical source of heat. The limit might be considered to be an area where the heat source is 40 degrees F., 9 degrees C. or above. There are other factors; for example movement in water makes it a better heat source than rock, unless the rock is permeable and has groundwater flowing through it.
