What is another type of form of thermal energy?

Question

i got geothermal and solar themal, is there anymore

Answer 1

heat on this planet is created by one of two sources; the sun and the compression of the earth's core so in the one sense the answer is NO there isn't anymore

but in the vernacular i think you mean- i would redefine geothermal into smaller groups.

energy can be gathered via:

ground water (commonly referred to as geothermal)

steam (iceland does a lot with steam)

hot water (rarely occurs but possible)

hot/cold air from below ground sources

wind results from thermal currents
