Still, it's coherent with GP's point: LPG and NG have the same finality, they get burned for energy in the same boilers with minimal changes.
In dense areas, the capital expenses of dedicated infrastructure are recouped with cheaper gas price, in sparse areas, we fall back on a more expensive fuel that can be transported on the existing generic infrastructure.
So the question than becomes: how dense do we need to get before dedicated garbage pipes make sense. Seems much, much more capital intensive than gas lines.
