Well, western society didn't adopted central planning, in a good part as central planning's failure to meet society's needs. Anyway, I don't think it's fair to criticize these efforts by depicting them as some sort of failure or the result of incompetence or shortsightedness. We have to have some humility when discussing these topics specially if they are from a field where we have no insight at all. In this case, we should keep inind that valuing energy efficiency and externalities is something that's extremely novel where society as a whole is just starting to take it's first steps. It's quite literally a highly transformative change that involves changes in all steps of an entire industry, including in building regulation and even urban planning. Change is happening as we speak, but what you are looking at, and criticizing, is society's first step in a much needed direction.
