Ocean Current Energy

Oceanic surface currents are an untapped source of energy. Because of their link to winds and surface heating processes, the ocean currents are considered as indirect sources of solar energy.

Tidal Energy

Tidal power is non-polluting, reliable and predictable. Undersea tidal turbines, like wind turbines but driven by the sea, and a variety of machines harnessing undersea currents are under development.

What is Ocean Energy?

With the oceans covering over 70% of the earth’s surface, they are the world’s largest collectors of the sun’s vast energy – and the largest powerhouse in the world. Just a small portion of the energy conveniently stored in the oceans could power the world.

Wave Energy

Waves get their energy from the wind. Wind comes from solar energy. Waves gather, store, and transmit this energy thousands of miles with little loss. As long as the sun shines, wave energy will never be depleted.

Offshore Wind Energy

Wind energy is an indirect form of solar energy. While some of the sun's energy is absorbed directly by the air, most of the energy in the wind is first absorbed by the surface of the earth and then transferred to the air by convection.

OTEC Energy

OTEC energy is based on the temperature differences between surface water, which is heated by the sun, and deep water, which stays very cold. OTEC uses the surface water to make steam and then pass the steam through a turbine generator to make electricity.

Tidal Energy News Villages set to draw tidal energy in the Sundarbans Villages set to draw tidal energy in the Sundar

Monday, 05 May 2008

KOLKATA: Till recently, the people of the Sundarbans archipelago in West Bengal had viewed the tidal waves flowing in from the Bay of Bengal as their source of misery. They feared the giant waves and cyclones which left a trail of destruction. Even during other times, the salty marshlands of the world’s largest mangrove swamp left little scope for any significant economic activity. They had resigned themselves to an eternal cycle of living life on the edge. But this may change in about two years, once the country’s first tidal energy project comes up. Tides then, will bring power...

Tidal Energy NewsTidal power trial approved in New Zealand

Monday, 05 May 2008

A Christchurch company has been given the go ahead to install an underwater turbine off Wellington's south coast to generate electricity from the Cook Strait tides. Greater Wellington Council has granted consent for a trial which is the first step in developing technology that Neptune Power believes could eventually satisfy a big part of the country's energy needs. The trial turbine, just south of Sinclair Head, should be up and running within 18 months and will power 400 Wellington houses through Vector's Wellington...

Wave Energy News3 Stanwood students try to harness wave energy

Monday, 05 May 2008

CAMANO ISLAND -- The three teenagers sat on the edge of their orange rowboat, looking out over the sparkling waters of Saratoga Passage.They saw more than the rising, falling waves, the glimmering sunlight and the choppiness of the water from the persistent maritime winds.They saw energy.Infinite, unbridled energy.Now, Jimmy Besancon, Derek Britain and Christy Swartz -- a trio of 16-year-old science buffs from Stanwood High School -- are researching how to convert the natural powers of Saratoga Pass into usable energy."Our goal is to create a usable amount of energy, created just by the...

Tidal Energy NewsRolls Royce in deep with tidal electric buy

Monday, 05 May 2008

Greenbang must have been having a quick snooze when Rolls Royce was talking up its latest renewables investment this month. It’s still an interesting deal - not to mention a chance to fall back on some lazy ‘it’s the Rolls Royce of energy deals!’ puns - so Greenbang feels obliged to share it with you today. Rolls has decided to take a 23.5 percent stake in TGL (or Tidal Generation Limited), a privately owned tidal energy firm, which it reckons will tie up nicely with its own efforts in the world of water energy. It’s not the first time Rolls has put its hand in...
