Renewable energy refers to power harvested from natural sources, such as the sun, wind, or water, which are not in danger of being depleted. The five renewable energies are:

  • Solar: power absorbed from the sun and converted to usable electricity through photovoltaic technology.
  • Hydropower: power created by channeling water to generate turbine-produced electricity.
  • Wind: power created by harnessing wind energy to generate turbine-produced electricity.
  • Geothermal: power created by harnessing the steam given off when water is pumped onto underground rocks naturally heated by the earth’s core.
  • Biomass: power created by harnessing the steam and heat given off by processing wood, green waste, garbage, or manure.
