Ocean power: A green option failing to make waves

Ocean power: A green option failing to make wavesInaugurated at La Richardais on the west coast by Charles de Gaulle in 1966, the plant produces about 500 Gigawatt hours of electricity per year -- enough to power 250,000 out of France's 30 million-odd households. It remains the sole power station of its type in France and one of only two large-scale tidal plants in the world -- the second largest after the Sihwa scheme inaugurated in South Korea seven years ago. "Ocean renewable energy has huge global potential, but is a largely untapped resource," Simon Neill of Bangor University's School of Ocean Sciences in Wales told AFP.
