A planned power plant in Wales is expected to produce enough electricity to power 155,000 homes for 120 years to achieve a Zero Carbon footprint. That’s enough to generate the need for 250 million barrels of oil each year.
This giant power plant will be built with an artificial lagoon with walls 9.6 km long. During high tide, the ocean water will move up the lagoon to turn the turbines; at low tide, the ocean water will flow into the lagoon and turn the turbines again.
How is it that we have not built power plants of this kind for decades?
It should also be noted that the lagoon can also be used as an aquaculture farm and serve as a marine sculpture garden, as well as a huge arena for sailing and sports cycling.
The plant was approved in June 2015 and construction will begin in 2017. The cost is estimated at about $ 1.5 billion and is subsidized by the government.

- Tidal energy uses tidal power to generate electricity by exploiting the difference in height between two basins.
- It is an intermittent energy but it is very predictable.
- By combining turbining and pumping, a tidal power plant can be a storage medium.
- The potential of tidal energy in the world is estimated at nearly 380 TWh / year, or 1.5% to 2% of annual global electricity production.
