Threat to Wind Turbines – bad vibrations

Medium-sized waves such as those occurring in even small storms, can snap offshore wind turbines like matchsticks. For wind turbines at sea with a cylinder diameter of eight metres, the most endangering waves are those that are more than 13 metres high and have an 11-second interval between them. Such storms and waves are frequent […]

Scientific testing to determine whether marine energy impacts on wildlife

UK scientists will measure the effect on the marine environment and wildlife of devices that harness tide and wave energy using sonar technology that has, for the first time, been successfully deployed on the seabed. Renewable energy from tidal currents can be generated using turbines in the tidal flow, and wave energy can be captured […]
