At lattitudes above the Tropic of Cancer or below the Tropic of Capricorn sunlight is reduced by the angle at which it strikes the earth. When the sun is directly overhead on a clear day, earth's surface receives roughly 1000 W/m^2. This averages out to 250 W/m^2 over earth's entire surface over the course of a 24 hour day. Earth's surface measures 500 trillion meters squared. So, please double check my math--125 quadrillion KW/hour.
