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 makes energy in its inner core in a process. called nuclear fusion. It takes the sunâs energy just a little over eight minutes to travel the. 93 million miles to Earth. Solar energy travels at the speed of light, or. 186,000 miles per second, or 3.0 x 108 meters per second. Only a small part of the visible radiant energy (light) that the. sun emits into space ever reaches the Earth, but that is more than. enough to supply all our energy needs.
