Our tides are driven by the gravitational effects of the sun and the moon on our seas. In the UK this creates a twice daily rise and fall in sea height. Electricity can be generated from tidal energy using barrages or dams in places where the tide moves in and out of a bay or inlet, or from tidal streams which drive underwater turbines.
