The point was that if you want energy in your home, you either (1) have to transport energy to your home or (2) place your home at the source of the energy. Since placing your home next to a large temperature differential is difficult, then the future will continue to rely on option (1), transporting energy to your home. And if energy has to be transported, its final price will not be zero, even if its wholesale price is.
- astrodust 10y agoNothing will ever be truly zero cost, but those costs can be minimal. A geothermal system for your house involves "transporting energy to your home" but the distances involved are so minimal that once installed it's next to nothing. > Since placing your home next to a large temperature differential is difficult... Well, that's wrong. Every house sits on top of a significant temperature differential which is why geothermal systems work. In large parts of the continental US the ground deep beneath the house maintains a consistent temperature year round. This can be used as a thermal sink in the summer, and a source of heat in the winter.
