Charles C. Mann Quote
Weaver could say something about the sun, though. In principle, the sun pours onto Earth enough energy—vastly more than enough—to provide all humanity with the necessary 128,000 calories a day. If solar energy could be utilized with full efficiency, the United States alone could sustain, energy-wise, a population over 40 times the present total population of the planet. The global population then being about 2 billion, Weaver was suggesting that in terms of energy the theoretical carrying capacity of the United States was about 80 billion people.
