Solar Energy: Refers to the conversion of energy from the sun into usable forms of energy, such as electricity.
Wind Energy: Refers to the generation of electricity through the power of wind turbines.
Hydro Power: Refers to the use of flowing water from streams, rivers, and oceans to generate electricity.
Geothermal Energy: Refers to the extraction of heat from underground sources to produce electricity or heat buildings.
Tidal Energy: Refers to the use of the rise and fall of tides to generate electricity.
Biomass Energy: Refers to the conversion of organic matter (such as crops or waste) into fuel for energy production.
Hydrogen Fuel Cells: Refers to the use of hydrogen fuel to power engines and produce electricity.
Ocean Thermal Energy Conversion (OTEC): Refers to the use of temperature differences in ocean water to generate electricity.
Wave Energy: Refers to the use of the motion of waves to generate electricity.
Concentrated Solar Power: Refers to the use of mirrors or lenses to focus sunlight onto a small area, which can then generate heat or electricity.
