Tidal energy harnesses the kinetic energy of moving water caused by the rise and fall of tides, which are primarily driven by the gravitational pull of the moon and the sun.

France holds the distinction of being the first country to successfully generate electricity from tidal power, with the construction of the world's first tidal power plant in 1966 at the Rance River estuary.

Tidal turbines, also known as tidal current turbines, are the most widely adopted technology for harnessing tidal energy. These underwater turbines capture the kinetic energy of moving water and convert it into electricity.

The tidal range, or the difference in water level between high tide and low tide, is a crucial factor in determining the amount of tidal energy available. Larger tidal ranges provide greater potential for energy generation.

Tidal energy offers multiple environmental benefits, including the reduction of greenhouse gas emissions, conservation of fossil fuels, and improved air quality, as it does not produce any harmful emissions during electricity generation.

China leads the world in terms of installed tidal power capacity, with several large-scale tidal power projects, including the world's largest tidal power station, the Jiangxia Tidal Power Station.

Tidal energy development faces several challenges, including high installation costs, the intermittent nature of tidal power due to the varying tides, and potential environmental impacts on marine life and ecosystems.

Tidal lagoons involve constructing a barrier or embankment across a bay or estuary, creating a reservoir that fills and empties with the tides, allowing for electricity generation.

Tidal range refers to the vertical difference in water level between high tide and low tide, which is a key factor in determining the potential for tidal energy generation.

China is home to the world's largest tidal power station, the Jiangxia Tidal Power Station, which has a total installed capacity of 3.6 gigawatts (GW).

Tidal current refers to the horizontal movement of water associated with tides, which can be harnessed to generate electricity using tidal turbines.

Tidal turbines are underwater turbines that are placed in tidal channels to capture the kinetic energy of moving water and convert it into electricity.

Tidal energy offers the advantage of predictability, as the tides are influenced by the gravitational pull of the moon and the sun, allowing for accurate forecasting of energy generation.

Tidal barrages are dams constructed across a tidal estuary, creating a reservoir that fills and empties with the tides, allowing for electricity generation.

Tides refer to the rise and fall of sea levels caused by the gravitational pull of the moon and the sun, creating the potential for tidal energy generation.
