Many hybrid systems are stand-alone systems, which operate “off-grid”—not connected to an electricity distribution system.
The term 'green energy' refers to any electricity generated from renewable sources. This includes solar, wind, hydro, geothermal, biogas, and biomass, rather than carbon-heavy sources like coal and natural gas. Green energy is created with zero carbon emissions, providing the highest net environmental benefit. Wind, solar, and hydro are the most popular forms of green energy.
These sources are renewable, meaning they can be replenished naturally and will never run out. They also emit no carbon dioxide, making them much cleaner than traditional power sources.
