Solar energy is produced from solar radiation. Sunlight travels through the upper parts of the earth's atmosphere. Once this sunlight reaches the surface of the earth, it must be captured so it can be turned into an usable energy source.
Energy may occur in the form of heat, light, movement, sound, or radiation. Human energy is usually expressed as muscle contractions and heat production, made possible by the metabolism of food that originally acquired the energy from sunlight.
