Most of the time when people suggest heat pumps they mean ground source ones. District cycle heat pumps would be the best solution from a cost and efficiency perspective, but require common action to install new infrastructure and so are harder to get than building level solutions.
Outside of that, unfortunately geothermal electricity tends to be very location and geology dependent. We absolutely should be taking full advantage of it where we can, but there are unfortunately limits on where is practical.
I wonder if geothermal is something they can do there.
It’s common in the Nordics and is usually the cheapest way to heat homes.
Last winter electricity was so expensive that district heating won.
But geothermal has otherwise been cheapest.
