Achieving Sustainability Doesn’t Require Laser-Precise Accuracy

The reason I showed you that is so I could tell you this: What we need to do to achieve a sustainable civilization does not call for anything like that level of precision. In particular, the sun bestows 6000 times more energy each day than all seven billion of us consume. Thus, in all our efforts to capture this energy in the form of solar PV, concentrated solar power, wind, hydro, biomass, etc., we can make a few mistakes here and there, as our overall efficiency needs to be no larger than 0.00013. That’s not a huge number.
One could argue, for instance, that the Germans (more…)
