This may sound very pie-in-the-sky, but how about this proposition: The amount of energy we should use is the amount that can be captured by = covering every existing roof with the highest-tech energy capture device = currently available--photovoltaics, I assume.
Surely someone has calculated how much energy this would capture, and = how it stacks up against our current energy use? Presumably we would = need to massively reduce energy use for this to come close to meeting = our needs, but ultimately it would seem the moral path to head down. = (Along with other renewables, especially wind, though I like this a lot = better than fueling machines with photosynthate when people are = starving) One could also do the same over every parking lot, street, etc, although = this would entail the energy and material cost of massive additional = construction.
