Tidal/wave power

Posted: 6 November 2000

Power that can be generated in coastal locations from the twice-daily ebb and flow of the tides. As the tide rises, water is allowed to flow through gates in the dam to fill the basin behind it. At high tide the gates are closed and as the tide falls the water in the basin is retained behind the dam. Once a sufficient head of water is built up, the water behind the dam is released and the potential energy it possesses is converted into kinetic energy which drives generators to produce electricity.
