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.
Though costly to implement, solar energy offers a clean, renewable source of power. The sun has produced energy for billions of years. Every hour the sun beams more energy onto Earth than it needs to satisfy global energy needs for an entire year. Solar energy is the technology used to harness the sun's energy and make it useable.
