Renewable energy: The tide is turning – energy-fuels – 08 October 2008 – New Scientist Environment

Renewable energy: The tide is turning *
New Scientist 08 October 2008 * Jason Palmer * Magazine issue 2677WELCOME to the Bay of Fundy in eastern Canada, home to the highest tides in the world. Here, 100 billion tonnes of Atlantic seawater flow in and out of the 270-kilometre-long bay every day. The sea level at Fundy rises by an average of 11 metres, reaching a maximum of 17 metres at the narrowest point, twice a day without fail, thanks to the moon’s gravitational pull. Could this tidal movement be used to generate power?The unwavering predictability and scale of the tides in some parts of the world make them an attractive renewable energy source. The World Energy Council estimates that Fundy’s tides alone could generate 17,000 gigawatt-hours (GWh) of energy per year. Some estimates put the energy in the world’s tides at as much as 1 million GWh per year, or about 5 per cent of the electricity generated worldwide, though ..
