A campaign has been launched by Bournemouth Borough Council to urge the government to stop the Navitus Bay offshore wind farm proposal.
The council wants to save England’s only natural World Heritage Site the, Jurassic Coast, as well as Poole Bay from industrialisation.
It also aims to protect local jobs and Dorset’s £1 billion annual tourism economy from the damaging impacts it claims the wind farm poses.
The wind project is a joint venture between Eneco Wind UK Ltd and EDF Energy Renewables.
In a letter to Prime Minister David Cameron, Leader of Bournemouth Council, John Beesley said: “Navitus Bay offshore wind farm would be highly visible from land and dramatically alter and damage the intrinsic appeal and beauty of what is currently a natural and untouched seascape.”
He said the industrial-scale turbines would be classed as permanent structures and fall into the “highest category of harm in terms of visual assessment”.
Mr Beesley added: “The ramifications of this proposed scheme are of national importance.
“Tourism lies at the heart of Bournemouth’s economy. Our natural coastline is the main reason why 6.7 million tourists from across Great Britain and overseas flock here every year.
“Changing the core appeal of our tourism offer by industrialising the beautiful coastal setting would have an unprecedented effect on the local economy.”
He said Bournemouth is “Britain’s premier resort” which competes with “the best in Europe” and damaging its progress “would be madness”.
He claims the national economic loss from this scheme is forecast at £6.3 billion.
A decision will be made by 11th September 2015.
