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. If 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 then 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.
