In Poland, there were some attempts at geothermal and there's a lot of uncertainties - drilling is *very* expensive, you need two shafts (in/out) and then you don't know for sure what you'll get. If it's 100°C it's a win, but then you may get 50°C and high mineralisation which quite useless. The best they got in Poland was 80°C and they're heating a whole district with it. There were many failed too.
