Mary W., New York Tidal energy — generated from the natural rise and fall of ocean tides — is one of the most predictable forms of renewable energy. Unlike wind or solar, which fluctuate based on ...

Looking to leverage all the motion in the ocean is UK startup Sustainable Marine, whose floating tidal turbine rotors just breezed through a testing regime that simulated 20 years of real-world ...

Harnessing tidal power around the UK's coast has so far been limited by the cost of the large dams and barrages required and unpredictable results. A British company, in conjunction with Oxford ...

Submerged in about 40 metres 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. It is a mark of durability that ...

At 800 times denser than air, water can drive smaller turbines to produce greater energy than wind. Referred to as marine current energy, tidal stream turbines work much like submerged windmills ...

Well, the Manta system is kind of similar, although it uses an underwater kite that "flies" in tidal or river currents. We've already heard about renewable energy systems that use aerial kites to ...

MCT’s power peak is four times the global record for a tidal-stream system set by the company in 2004, according to U.K.-based renewables journal REFocus, and 30 times more than the output from ...

Tidal energy systems need strong currents to make electricity efficiently. MeyGen plans to add 20 turbines in 2030 to produce more electricity, after needed upgrades to the electricity grid are ...

New Bedford-based Littoral Power Systems looks to show the promise of tidal wave energy to the world. Here's why LPS chose SouthCoast to be its home.
