Providing decent living with minimum energy: A global scenario

2. I don't see it happening in the foreseeable future, either.

Not for the same reasons, though. (In fact, I don't think complexity or expense are real problems at all.) In my opinion, the main impediments are political. All the rich countries are still pursuing pro-growth policies that increase energy and material use, and there's no hint of any possible change. Almost nobody - maybe literally nobody - in a position of real influence is open to alternatives, and for the most part the people with real power are actively hostile to those kinds of changes. Nor is there significant public pressure.
