Editing Tidal power (section)

=== Tidal barrage ===
{{Main|Tidal barrage}}

Tidal barrages use [[potential energy]] in the difference in height (or [[hydraulic head]]) between high and low tides. When using tidal barrages to generate power, the potential energy from a tide is seized through the strategic placement of specialized dams.  When the sea level rises and the tide begins to come in, the temporary increase in tidal power is channeled into a large basin behind the dam, holding a large amount of potential energy.  With the receding tide, this energy is then converted into [[mechanical energy]] as the water is released through large turbines that create electrical power through the use of generators.<ref>{{cite book|last=Evans|first=Robert|title=Fueling Our Future: An Introduction to Sustainable Energy|url=https://archive.org/details/fuelingourfuture00evan_0|url-access=registration|date=2007|publisher=Cambridge University Press|location=New York}}</ref>  Barrages are essentially [[dam]]s across the full width of a tidal estuary.
