Sea energy ‘could help power UK’
`Wave and tidal power can provide a fifth of the UK’s electricity needs, according to a new report. [..]
Despite Britain’s long shoreline and the vast power contained in its breakers and tides, the Carbon Trust believes only about one fifth of the country’s electricity could economically come from the sea.
It says that wave farms could generate 50 terawatt-hours (TWh – one thousand million kilowatt-hours) per year, and tidal stream installations a further 18TWh.’
