Researchers have cataloged 426 potential tidal-stream turbine sites spread across 19 countries, quantifying a theoretical energy resource of 1,000 terawatt-hours per year from 262 of those locations.

Recent disruptions to oil supply in the Middle East have sent energy prices soaring, reminding countries how vulnerable they ...

Tidal power is a fantastic source of clean, predictable energy – if you can harness it. It's proven immensely difficult due to a range of factors, but engineering giant SKF says it's making major ...

Submerged in about 40 meters (44 yards) of water off Scotland’s coast, a turbine has been spinning for more than six years to harness the power of ocean tides for electricity—a durability mark that ...

Add Yahoo as a preferred source to see more of our stories on Google. One of the most powerful underwater tide-riding turbine projects has secured funding from the European Union’s Innovation Fund.

Tides are predictable years in advance, unlike wind or sunlight. Because of this reliability, harnessing the energy of ocean tides has long appealed to engineers. The difficulty lies in building ...

Cape Sharp's five-storey-high turbines, destined for the Minas Passage, are expected to generate enough electricity to power ...

Marine energy is renewable and generally predictable. It could thus compensate for the unplanned intermittency of solar and ...
