Industrial scale geothermal makes sense, but everything I've seen about small-scale geothermal and geoexchange (i.e. for a single structure) shows that it doesn't make a whole lot of sense in comparison to air source heat pumps. They're slightly more efficient, but significantly more expensive and complex. I know they have their fans, but nothing I've ever seen shows a real payback.

Really, the technology is already there for electrification of heating at costs that rival gas. We're getting to the point where you probably shouldn't even be allowed to install a gas furnace in newly constructed buildings in places like BC, Manitoba or Quebec (they still make the most sense in places with higher grid emissions).
