Hadn't looked at it that way yet, that actually sounds really attractive. If they can be maintained and operated at under 1k per house per year then that's competitive with what I pay now.
I wonder why it's so cheap when calculated this way it seems competitive with solar panels when I expected it to be a factor ten more expensive (of course solar panels wouldn't really work that far north).
Especially not if we manage to electrify everything. The average American uses a little over 9kW of primary energy continuously. You can probably safely divide that by three if you use electricity, but still.
