So the power required would be almost 4 orders of magnitude smaller than what you assume (divide by 8760). No? Telmo. > Now let's work on findings percentages.

Or you could divide >>> the amount of ENERGY solar cells produce in one hour, 1.5*10^11 watt-hours >>> by the amount of ENERGY required to operate technology for one hour >>> 1.5*10^17 watt-hours of ENERGY, and we still get the pure number .000001. >>> Or you could divide the amount of ENERGY solar cells produce in one year, >>> 1.3*10^15 watt-hours of ENERGY, by the amount of ENERGY required to operate >>> technology for one year, 1.3*10^21 watt-hours of ENERGY, and we STILL get >>> the pure number .000001 And that is why I originally said photovoltaics >>> provide .0001% of demand.
