The total power consumption by all humans on earth is approximately 1013 W. Let’s compare this to the power of incoming solar radiation. The intensity of radiation from the sun at the top of the atmosphere is 1380 W/m2. The earth’s radius is 6.37 × 106 m.a. What is the total solar power received by the earth?b. By what factor does this exceed the total human power consumption?
