Have you heard of the Swansea Bay Tidal Lagoon?  This power generator will use the rise and fall of ocean tides to provide renewable electricity to power 155,000 homes, and it will last for 120 years!

This power plant will supply a solution to man’s energy needs as we step further and further towards renewable resources.  Though not completed yet, the structure will provide enough electricity to replace over a quarter million barrels of oil every year.  It will leave a very small carbon footprint too.

Harnessing the ocean’s tides has been around since 1966, but the Swansea Lagoon is the first in line to utilize a new method.

How it works?

This artificial “tidal lagoon” will hold a large sum of water and is nearly six miles long.  At high tides the lagoon with capture and hold the seawater in the 4.5 square miles in incorporates.  At low tide the water in the lagoon will be, up to, 27 feet higher than the H2O outside the walls.  The water will then be routed through 26 turbines, flowing out to sea, until the water levels on both sides equalize.

At high tide the flow is reversed, keeping the sea back out of the lagoon until the maximum height is reached.  The water is then set free, through the turbines, and fills up the lagoon.

To put this all into perspective, the amount of water that passes through the turbines could fill 100,000 Olympic swimming pools…each day!

The Swansea Bay Tidal Lagoon will not only produce clean energy, but it will also be used as a sports arena, seaside sculpture garden, and aquaculture farm as Good News Network reported.  Kelp, oysters and other local sea crops will be farmed in the aquaculture farm.  The sports that could utilize the lagoon are sailing and cycling.

Sculptures that appear to disappear in the water, or emerge from it as the tides roll in and out, are planned to be implemented in this structure.

Because it has some of the highest tidal differences, Swansea, Wales was chosen for the location of beautiful structure.  The tides will maximize the amount of water used for the turbines to produce 420-gigawatt hours per year.

Utilizing the ocean’s tides for clean energy is another way for us to go green.
