The sun is the most important energy source of all. Without the sun's energy heating the Earth's surface, there would be no potential for life. The sun is continuously radiating energy totaling 400 trillion trillion watts. Earth is ideally positioned in its distance from the sun so that the heat energy from the sun is not overbearingly hot, as on closer planets (Mercury, for example), and not too small to sustain temperatures that are suitable for life.

The sun's energy can also be harnessed through the technology of solar cells, which convert the sun's energy (in photons) to usable electricity. Solar energy can power anything from a calculator to cars to entire buildings.
