How is tidal energy harnessed?

Tidal energy is harnessed through the use of tidal power plants and underwater turbines. These technologies harness the power of the ocean's tides to generate electricity in a renewable and sustainable way.

Tidal Power Plants

Tidal power plants work by capturing the energy of the tides as they flow in and out. These plants typically consist of large barrages or dams that are built across a tidal basin or estuary. As the tide comes in, water is trapped behind the barrage. When the tide goes out, the water is released through turbines, which generate electricity.

Underwater Turbines

Underwater turbines are another way to harness tidal energy. These turbines are placed on the seabed in areas with high tidal flows. As the tides move back and forth, the water flow rotates the turbines, which in turn generate electricity.

Environmental Benefits

Harnessing tidal energy has numerous environmental benefits. It is a clean and renewable energy source that produces electricity without emitting greenhouse gases or other pollutants. Tidal energy is also predictable and reliable, as tides are influenced by the gravitational forces of the moon and sun.

Additionally, tidal power plants and underwater turbines have minimal visual impact and do not require large amounts of land, making them ideal for coastal communities.

Overall, tidal energy is a promising technology that has the potential to play a significant role in our transition to a more sustainable energy future.
