The building I recently moved into is distinguished by the technology which it uses for heating and cooling. Rather than use electricity or fossil fuels to generate heat directly, it takes advantage of the way in which the ground maintains a fairly constant temperature all year round, if you dig down deep enough.
One big advantage of this approach – when it comes to the residents of the building – is that it takes away the risk associated with volatile fossil fuel prices, and reduces the amount of electricity required. People living in such a building have a better guarantee that they will be able to heat their homes than people living in conventional structures will. This could be especially important if fossil fuel prices spike in the future, or even if they just progress relentlessly upward.
It can be challenging to identify situations in which the economic self-interest of individuals aligns closely with the aim of reducing greenhouse gas pollution. Geothermal heating and cooling seems to be one of the places where those interests align.
