Tidal turbines are devices that convert the kinetic energy of moving water in tidal currents into electricity.

Tidal energy is predictable because tides are driven by the gravitational forces of the moon and sun, making it a reliable source of energy.

As of 2023, the United Kingdom has the highest installed capacity of tidal energy in the world, with several operational tidal turbine projects.

The Rance Tidal Barrage in France is the largest tidal barrage in the world, with a total installed capacity of 240 MW.

Tidal lagoons are artificial lagoons that are filled and emptied with the tide, generating electricity as the water flows in and out.

Tidal energy development can disrupt marine habitats, potentially affecting marine life and ecosystems.

Tidal turbines are generally considered to have the lowest environmental impact among tidal energy technologies, as they do not require major infrastructure changes or disruption of marine habitats.

The average capacity factor of a tidal energy project is typically in the range of 20-30%, meaning that it generates electricity for approximately 20-30% of the time.

China has the most ambitious plans for tidal energy development, with plans to install up to 100 GW of tidal energy capacity by 2030.

The high cost of developing and installing tidal energy technologies is a major challenge, making it difficult to compete with other renewable energy sources.

Tidal lagoons are still in the early stages of development, with only a few pilot projects operating worldwide.

The potential global tidal energy resource is estimated to be in the range of 100,000 GW, significantly higher than other renewable energy sources.

When selecting a site for a tidal energy project, factors such as tidal range, water depth, current speed, and environmental impact are all taken into consideration.

The typical lifespan of a tidal energy project is around 20-25 years, similar to other renewable energy technologies.

Government policies play a crucial role in promoting tidal energy development by providing financial incentives, setting regulatory frameworks, and conducting research and development.
