![]() Cumulative energy produced from global wave and tidal stream sources grew almost 10-fold between 20. Renewable energy is a rapidly growing sector on a global scale and electricity generation from tidal stream generators in areas of high tidal flow is increasing rapidly (Ocean Energy Systems, 2019). The results indicate that the risk of collisions between the tidal turbine and porpoises is low this has important implications for the potential effects and the sustainable development of the tidal energy industry.Īnthropogenic structures in the marine environment are increasing in number with ongoing oil and gas extraction, and the expansion of marine aquaculture and renewable energy (Stojanovic & Farmer, 2013).The data show that porpoises effectively avoid the turbine rotors, with only a single animal clearly passing through the rotor swept area while the rotors were stationary, and none passing through while rotating. Echolocation clicks from 344 porpoise events were localized close to the turbine.Harbour porpoise movements were monitored in three dimensions around a tidal turbine for 451 days between October 2017 and April 2019 with a 12-channel hydrophone array. ![]() Information on the fine scale behaviour of animals close to operational turbines is required to inform regulators of the likely impact of these new technologies. Tidal energy generators have the potential to injure or kill marine animals, including small cetaceans, through collisions with moving turbine parts.
