What Is Renewable Energy?

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
• Hydropower
• Wind
• Geothermal
• Biomass

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
