SOLAR ENERGY

energy obtained from the sun, energy of the sun

Solar energy is energy from the sun. It supports life on Earth and drives the Earth's weather. Solar energy predominantly arrives in the form of infrared, visible and ultraviolet light, and is either returned back to space or is absorbed. Nearly all of the absorbed energy is converted directly to heat, with a small but important fraction converted to chemical energy, such as in ozone production, photosynthesis or photovoltaic energy production.
