Tidal stream
Turbines are placed into fast-flowing bodies of water. The flow turns the rotor blades to generate power. This is a horizontal axis turbine, one of many types used in tidal stream projects

Tidal barrage or lagoon
Tidal barrages are built across river estuaries, while tidal lagoons enclose a body of water off the coastline. With both, water collects behind a wall at high tide and is released to drive a turbine
