When thinking about heating with geothermal energy or ground heat, I have a
feeling that it is not the right way to go, but can't think of sufficient
reasons to back up this feeling. One reason is the electricity consumption
and dependence on electricity, but...

What do you know about ground heat and its sustainable conversion into space
heating? Any experts out there?

Thanks
