EWEA Vice-President
Jos Beurskens, 2001
“We need to avoid the situation in the Netherlands where one faction wants to save nature and the other to introduce renewables. If you don’t bring them together it will be disastrous.”

Uncertainties – the main ones!
• Birds – displacement, barrier effect collisions
• Fish – electromagnetic effects; change in fishing effort
• Marine mammals – underwater noise
• Seascape – how evaluate, layout?
• Cumulative assessments – how?

Sharks, skates and rays• Will windfarm cables affect behaviour or
populations?
• Many species depleted in UK waters
• Use inshore sandbanks for feeding, breeding, nursery areas
• Lab tests show avoidance and attraction
• Shielding and burial of cables
