Twice a day the oceans rise and fall due to tides. This movement of water contains a great deal of energy. This energy can be harnessed as tidal power.
Due to the complexity of these projects they tend to be on a major scale. The UK is currently pioneering test projects of this technology. It is hoped that, in the future, tidal power could supply up to 20% of the UK’s energy demand.
Scottish Power Renewables are currently developing a number of tidal power projects. Read more – https://www.scottishpowerrenewables.com/pages/tidal_energy.aspx
