Something is seriously wrong with these numbers. My handy reference lists the solar constant at 1340 W/m^2, and the mean radius of the Earth is 6.37x10^6 m. Multiply that out, divide by 3 billion people, and you get an approximate natural energy budget of 5.6x10^4 KW per person. We should be able to use whatever fraction of that we care to actually harvest without fear of creating a global heat problem.
