Well, obviously in can, but what would this mean in practice? A quick google reveals that a US citizen consumes about 10^4 W of power (amortising industrial and domestic power consumption over the whole population, I assume). This means that 60 billion people will consume 6x10^14 W. Solar panels on the surface of the Earth can generate 100 Wm^-2 during daylight or 50 Wm^-2 on average because half the day is night (and less because it's often overcast). This means our putative population will require 1.2x10^13 m^2 of solar panels, which is 12m km^2 or a square array 3500km on a side - an area somewhat larger than the US. >> But statements like your prove that you don't get the issues, are >> basically uninformed and are a good reason why this list has gone to >> hell. > > You are an idiot.
