Solar Energy Cycle
Sun’s heat drives the wind & this wind energy can be captured with wind turbines to produce electricity
Water cycle Sun’s heat cause water to evaporate This water vapor turns into rain or snow & flows into rivers This energy is captured as ‘hydro- electric energy’
Biomass
Bioenergy
Hydropower/Hydrogen energy
Geothermal Energy
Ocean’s force of tide & wave can be used to produce energy
