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.
The sun's energy heats the surface of the Earth, which in turn  heats the air just above it. Where the suâ¦n heats the surface of the  ocean, evaporation occurs, which moistens the air. Warm, moist air  carries a very large amount of energy that is the power source for  thunderstorms.
