Right, this is more the angle that I was going for. PO + GW = Conservation + Efficiency + Renewables and probably some nukes, LNG, etc.

One of my fears is that if we wait too long, we will burn through the rest of the coal left in the ground really quickly, superheat the atmosphere and be no closer to sustainability.

peakguy I think you are right, that's what we'll do. Why? Because that's the path that requires the least real thought and planning, it's the plan that's the most yeastlike.
fleam, the path that is most yeast-like is to produce alcohol until it kills you. I kind of think ethanol fits the description!
