Sunlight And Solar Energy
  • In the form of heat and light, solar energy can cover all our energy needs in a clean, versatile manner.
  • Photovoltaics, or Solar panels with silicon cells, convert light into electricity as the photon rays of the sun charge up the cells.
  • Solar-thermal power plants use the heat of the sun along with lenses to focus the sunlight in a concentrated place, to heat water or other substances. This can be used for the hot water needs of households, or to drive a turbine for generating electricity.
