Green Technology

The oceans and the power of the waves and tides waves might be the source of your electricity someday.  Systems that can convert the constant undulation of the waves into energy can harness  what seems like an unlimited renewable energy source.

"...  potential to be one of the most environmentally benign forms of electricity generation ... wave energy around the British Isles ... estimated to be equivalent to three times current UK electricity demand, ..."

Pelamis  are minimally impactful ... their visual impact is small as they are half submerged so are not nearly as visibly on the horizon as wind trubines.  They appear to have minimal impact on marine life as well and can be removed much easier than a wind turbine.

They currently have installations undergoing tests in Portugal and Scotland. 

Pelamis has their HQ in Edinburgh, Scotland.

... "He called for Britain to make smart investments through greater technology prioritisation and to move away from technology neutrality. This new approach, outlined in a new report, means public support will be focused on emerging low carbon technologies and industries that will have the maximum impact on cutting carbon and generating UK economic benefit. " ...

Ocean Power Technologies is testing a buoy that harnesses wave energy to make power  ... unlike off shore turbines  theses are close to the ground and are hardly visible ... eliminating the "not in my backyard problem" from shore communities.

" ... a leading renewable energy company specializing in cost-effective, advanced, and environmentally sound offshore wave power technology. ... PowerBuoy® system extracts the natural energy in ocean waves,... is a “smart” system capable of responding to differing wave conditions."

" ... ocean trials have been conducted off the coast of New Jersey to demonstrate the concept of using a floating buoy to capture wave energy and convert it into electricity. ..."

There seems to be a lot of energy in waves.  Anyone who has body surfed them in from the sea to the beach knows that.  So how do you get electric from this potential?

EMEC, in Orkney, Scotland is hoping to answer this question.

"... established to help the evolution of marine energy devices from the prototype stage into the commercial market place.... by harnessing the power of waves and tidal streams."

" ...  first centre of its kind ... anywhere in the world, ... opportunity to test full scale prototype devices in unrivalled wave and tidal conditions. ... connected to the National Grid via seabed cables running from open-water test berths. ..."
