There are a few different types of renewable energy, the most common being solar. solar, wind, wave, water, tidal, geothermal and maybe wood (unlikely)
water and air
allrneable energy are nonexausable.
Solar Power, Wind Power and Geothermal are three different types of green (renewable) energy.
Solar Energy - energy from sun lightWind Energy - energy from the windGeothermal Energy - thermal energy stored in the earth.Biomass - biological material from living, or recently living organismsHydropower - energy generated by waterIf you want to read examples of these type of renewable energy, follow the link.
