Power generated from sources like solar, wind, geothermal, biomass, and low-impact hydro installations is commonly known as green or environmentally friendly electricity. Renewable energy sources, such as solar and wind power, have a significantly reduced environmental footprint compared to traditional fossil fuels like coal and gas. While all forms of electricity generation leave some footprint, the cleanest options tap into the Earth’s natural energy flows. These sources, collectively known as renewable energy, are sustainable as they don’t deplete finite resources. When harnessed for clean electricity generation, it is commonly termed green electricity.
Green electricity flows through and is distributed via the same grids that transport power generated by alternative technologies. The eco-friendly electrons generated by solar panels or hydropower facilities intermingle with electrons produced by various sources. In the grid, it’s challenging to trace the origin of specific electrons, making it impossible to discern the precise type of electricity powering a home or office building.
Examples of Green Energy
Green Energy is derived from non-fossil fuel sources that nature continuously replenishes. Currently, there are four primary green energy sources:
- Hydropower- Generated by the force of water cascading over a dam, driving turbines to produce electricity.
- Wind- This propels turbines converting mechanical energy into electrical current.
- Sunlight- This is converted into electricity through the use of solar panels or solar thermal power plants.
- Biomass- A broad category encompassing materials like plant waste, especially wood, which can be burned to generate electricity.
Additionally, there are several less commonly utilized energy sources:
- Geothermal energy: Harnessed from hot water deep beneath the Earth’s surface.
- Marine Energy: Marine energy is a collective term for various technologies related to harnessing energy from seas and oceans.
