70% of the globe is covered by Ocean which is minimally used. If we covered 10% of that with solar we get .7 * .1 * 196.9 * 10^6 mi * 2.59e+6 (miles to meters) * 100 watts/meter average * 20% efficiency ~= 713959400000000 watts / second. Or 100kw 24/7 per person for a population of 7 billion. That's plenty of energy cover loss of fossil fuel, and to upgrade everyone's lifestyle for the next billion years. Granted, nothing keeps up with exponential growth. But, world population does not seem to be on that trajectory long term. |
