Hydropower: Energy generated from flowing water through the use of turbines.
Geothermal Energy: Energy generated from the Earth's internal heat through the use of geothermal power plants.
Biomass Energy: Energy generated from organic matter such as wood, crops, and waste through the use of combustion or conversion to biofuels.
Ocean Energy: Energy generated from the tides, waves, and currents of the ocean through the use of tidal and wave energy systems.
Hydrogen Fuel Cells: A technology that converts hydrogen into electricity, heat, and water through a chemical reaction.
Methane Digesters: A process that converts organic waste into biogas, which can be used as a fuel source.
Biofuels: Fuels made from renewable sources such as vegetable oils, animal fats, and ethanol.
Concentrated Solar Power: Uses mirrors or lenses to focus sunlight onto a receiver, which produces heat that can be used to generate electricity.
Landfill Gas Recovery: A process that extracts methane gas from landfills and converts it into electricity.
Anaerobic Digestion: Breaks down organic material in the absence of oxygen to produce biogas that can be used as a fuel source.
