12.2 trillion watt-hours converts to 12,211 gigawatt-hours, and based on 8,760 hours per year, and 197 million square miles of earthâs surface (including the oceans), the earth receives about 274 million gigawatt-years of solar energy, which translates to an astonishing 8.2 million âquadsâ of Btu energy per year.
Recall that, averaged over the surface area of Earth's globe, about 342 W/m2 of energy reaches the top of Earth's atmosphere. Recall also that the peak of the Sun's EM emissions are in the visible light region of the spectrum.
