Gallery: Is Tidal Power Damaging the Welsh Coastline?


Tidal power has the potential to provide countries with all the energy they could need – but at what cost? A team of scientists in Wales just launched a study to investigate the impact of tidal energy generation on Pembrokeshire’s coastal and marine environments. The team will work with 3D models of the seabed to study the effects of turbulence and underwater background noise on marine wildlife and fish behavior.

    Dams in the Pacific Northwest and California block passage for fish species such as Pacific Salmon and Steelhead. Fish ladders and other passage facilities have been largely ineffective in mitigating the negative effects on salmon populations. In small hydro setups, since no dam is required the safety risks of having a dam are avoided, avoiding the risk of a flash flood caused by a breached dam, eliminating the need for fish ladders and reducing silt accumulation and occurs behind most dams.

    Tidal and wave farms can result in the displacement of commercial and recreational fishermen from productive fishing grounds, can change the pattern of beach sand nourishment, and may represent hazards to safe navigation.

    Oh noes! Clean, renewable power harms a beach? Will you hippies make up your minds, already?! Solar panels wasted land, wind mills kill birds, tidal ruins beaches. You people are starting to irk me.

    Do you want clean consistent power or do you want another national park. Just like hydroelectric dams have had their share of environmental woes. Were not gonna build any new huge dams in America, either they’ve already been built on every major river or protests led to their cancellation. I think America should invest in small hydro. There are already over 70,000 dams in America, only 2,400 of which generate any power. Run of the river hydro plants can generate power for small towns and villages with minimal transmission infrastructure; you can tie it in with the local grid.

    I feel that this is a great way of exploring our need for future energy as I’m working on a project through my website.
