    concluded that there would be only a benefit to sea life including mammals and cetaceans?

    •  I think this varies by technology (3+ / 0-)

      the design I based my diary on happens to do without turbine blades so the environmental risk on sea life is likely lower, not sure if there is a definitive evaluation of this though.

      However, compared to the relative impact of nuclear, coal, gas...I think the benefit/risk ratio looks good on this one.

        on this project in Scotland

        In addition, Wavegen has continued to refine the turbine design through a programme of testing and modelling. An environmental assessment of the site and surrounding area is nearing completion. The work undertaken has been carried out by independent specialists so that SWEP can be designed with minimal effect on its surroundings. Work undertaken includes:

           * Landscape and visual assessments
           * On shore noise assessments
           * Marine habitats and ecology assessments
           * Archaeology studies
           * Transport and route access assessments

        They are designing with minimum effect in mind which one would expect.

        I appreciate your diary. May I suggest that you keep posting on this subject and please include the environmental assessments.

          Last April, ministers refused an application for 181 giant wind turbines at Barvas Moor on Lewis. The proposal had bitterly divided the island with the communities near Siadar being among those most strongly opposed.

          "We have always taken the view that the Outer Hebrides has a wide range of potential opportunities in the production, storage and use of renewable energy and wave power is certainly an exciting prospect for the future."

          Environmentalists were also positive. RSPB Scotland, which opposed the giant wind farm, welcomed the new wave energy farm.

            People don't like the sight of them, which, pardon me the pun, is teh short sightedness :P

            •  That is why I believe offshore wind turbines (3+ / 0-)

              located in deeper water and over the horizon offer real potential.

              Stronger more consistent wind means more power generated and out of sight of land means less NIMBY opposition. Also deeper waters are sometimes further from bird migration routes.

              The technology to deploy turbines in deeper water isn't quite there yet but its coming, or so I read.

            •  Not only the "sight" of wind farms (3+ / 0-)

              There are land use and shore use conflicts. There is the damage to raptors and bats which then increases rodents and insects on the ground. But that's another issue.

              This wave action technology looks promising.
