I think you should read up on earth-source heat exchangers (often
erroneously called "geothermal"). They aren't inexpensive to
install, but they're the most practical "sustainable" heating source.

There are dozens of websites of interest, including many government
websites in the US and Canada that describe how they work and what
efficiencies you can gain with them. They are powered by
electricity, but use roughly 25% as much electricity to heat and cool
your home as using electrical heating. You could also consider an
air-source heat pump, but they aren't as efficient. However, the
payback period is shorter since they're not much more expensive than
regular heating systems.

Hi,
Here I saw a few working geo thermal heat exchange systems installed by
local firm. It's great. Only problem is it costs ~25,000.00CAD for the
time being. If I were building a new house, I'd give serious
consideration to it.
