is it possible to every country to use geothermal energy?
i mean can for example european countries use it?
whats the effect of geographic situation on

Sure, if you drill far enough down.
Might be more economical than nuclear.

Yes, at least were low grade (heat pump assisted) geothermal energy is
concerned. Higher grade geothermal is technically available anywhere
but the cost is too high per kwh to justify harvesting it anywhere but
places with high level of volcanic activity, Iceland for example.
The major cost issue is that with hot dry rock geothermal (the holy
grail of geothermal energy) no one has figured out how to transfer the
heat quickly enough though a single drill point to make it economical.
Drilling deep wells is expensive and drilling many such well, to get
the output to a reasonable level, is simple too expensive. At least
that is my understanding of the situation.

We have geothermal power stations on the east side of the High Sierras
and near the Salton Sea in California. Where ever the earth's crust is thin
enough to bring the heat close enough to the surface there may be a possible
location.

In Sweden they use more and more heat exchange pumps.
Works like a refrigerator but in reverse order.
It pays itself back after 5-6 years.
The pump needs some electricity but it's minor compared to what you
would spend on to heat your house.
