By geothermal, do you mean digging 30 meters into the ground for heat/cold? I've read that it doesn't work in densily populated areas where every system is very close to each other. Unless you have one installation per street. We also have heat exchangers for warming your home but then you have a noisy box outside your house or on your balcony.

Densely populated areas in Finland are typically heated with district heating, rather than each house individually. https://en.m.wikipedia.org/wiki/District_heating https://en.m.wikipedia.org/wiki/District_heating Right now the energy for district heating in Helsinki is a mix of fossil fuels and using waste sources of heat like data centre heat. Renewable energy sources are currently being evaluated for this, with deep geothermal (up to several kilometres deep) being one source. https://www.hel.fi/uutiset/en/helsinki/helen-investigates-possibilities-of-geothermal-heat-in-helsinki https://www.hel.fi/uutiset/en/helsinki/helen-investigates-po...
