1. What is a tidal barrage and how does it make electricity?A tidal barrage is a big wall built across a bay or estuary. It uses the ocean’s rising and falling tide to fill a basin, then releases the water through turbines that spin and generate power.
2. Where are tidal barrages usually built?They are built in places with big tidal ranges, like the Rance River in France, Sihwa Lake in South Korea, and the Bay of Fundy in Canada. Other studies are looking at sites in the UK and Australia.

Head: The difference in water level or pressure between two points, crucial for generating power in hydroelectric and tidal systems.
Estuarine Ecosystem: The complex biological community and physical environment found where freshwater rivers meet saltwater oceans.
Decarbonization: The process of reducing or eliminating the emission of carbon dioxide and other greenhouse gases from human activities.
