Chúc các bạn thi tốt! | Tidal Power Undersea turbines which produce electricity from the tides are set to become an important source of renewable energy for Dritain. lt is still too early to predict the extent of the impact they may have. but all the signs are that they will play a significant role in the future. A Operating on the same principle as wind turbines the power in sea turbines comes from tidal currents which turn blades similar to ships propellers but. unlike wind the tides are predictable and the power input is constant. The technology raises the prospect of Britain becoming self-sufficient in renewable energy and drastically reducing its carbon dioxide emissions. lf tide wind and wave power are all developed. Britain would be able to close gas coal and nuclear power plants and export renewable power to other parts of Europe. Unlike wind power which Britain originally developed and than abandoned for 20 years allowing the Dutch to make it a major industry. undersea turbines could become a big export earner to island nations such as Japan and New Zealand. B Tidal sites have already been identified that will produce one sixth or more of the UK s power - and at prices competitive with modern gas turbines and undercutting those of the already ailing nuclear industry. One site alone the Pendand Firth. between Orkney and mainland Scotland could produce 10 of the country s electricity with banks of turbines under the sea and another at Alderney in the Channel islands three times the megawatts of Britain s largest and newest nuclear plant Sizewell B in Suffolk. Other sites identified include the Bristol Channel and the west coast of Scotland particularly the channel between Campbeltown and Northern Ireland. C Work on designs for the new turbine blades and sites are well advanced at the University of Southampton s sustainable energy research group. The first station is expected to be installed off Lynmouth in Devon shortly to test the technology in a venture jointly funded by .
