Quizplus · Accepted Answer

The amount of energy that the world uses in a year is roughly estimated to be around 600 exajoules (EJ), while the amount of solar energy that reaches the Earth's surface in just one hour is around 173,000 terawatts (TW). One exajoule is equivalent to one trillion (1,000,000,000,000) joules, and one terawatt is equivalent to one trillion (1,000,000,000) watts. Therefore, the energy that the world uses in a year is only a tiny fraction (about 0.00003%) of the energy that the sun delivers to the Earth's surface in just one hour.
