Mr Pearce and others are fighting for wind farms to be linked at an offshore hub - sometimes called a ring main - so that multiple cable trenches would not have to be dug across the Norfolk countryside, rather than a trench being needed for each new project.
A leading charity has expressed concerns about the potentially devastating impact of ScotWind on Scotland’s seabirds. The Royal Society for the Protection of Birds (RSPB) Scotland says the scale of new offshore wind farms could “accelerate some seabird species towards extinction” unless there’s major action.
The Britain’s Got Talent judge is angry at plans by German energy company RWE to erect the giant towers of up to 1,066ft within sight of the West Sussex coast. She has offered her support to thousands of local campaigners battling to stop the new site called Rampion 2, which will occupy an area the size of the Isle of Wight just eight miles from shore.
Ms Keith said that while fishermen supported the aim of lowering carbon emissions, the INTOG consultation was being “rushed through with scant attention to detail”. “The whole process should be slowed down so that the industry can gather and fully assess fishing data from these areas,” she added.
The components – weighing a combined 126 tonnes – fell from lifting equipment during planned maintenance work, the developer stated. Some of the turbine components have broken up and debris has come ashore.
Swedish energy company Vattenfall said turbine parts fell into the sea at the Ormonde Wind Farm six miles (10km) off the coast at Barrow, Cumbria. Debris from the incident could be widespread according to the operator. The Ormonde facility was placed in service in 2011 and consists of 30 5-MW turbines. The facility was undergoing maintenance when the equipment was dropped.
Debris from an offshore wind farm caused by a "disappointing" maintenance work error could be widespread, an operator has warned.
Experts in Scotland found exposure to electromagnetism triggered 'behavioural and physiological responses' in around 60 brown crabs at the St Abbs Marine Station. ...The cables for offshore renewable energy also emit an electromagnetic field that attracts the crabs and causes them to become stationary, which affects breeding and migration, according to the team.
Cllr Andrew Hinchliffe feared beautiful views, such as those enjoyed from Llanfairfechan, could be "destroyed". “From where we are now, we can only see the present turbines over Llandudno, which is very surprising, but these will be double the height and extending right across the vista, which I find very difficult,” he said. “I think this is far too much. If they were going to build this, surely turbines could be much further out and less intrusive on our landscape.
Analysis by Professor Gordon Hughes of the School of Economics at University of Edinburgh shows that the cost of consumer subsidies to offshore wind per unit of electrical energy generated (MWh) has risen and continues to rise year on year. This is contrary to claims by the UK government and other reports that claim these costs are dropping. Below is an excerpt from a report explaining Prof. Hughes's findings. The full report can be accessed by selecting the document link(s) on this page.
They warned: "Local communities are rightly concerned about the sheer amount of infrastructure built by individual offshore wind companies and the government must act. "The government should urgently carry out an audit of all outstanding plans for onshore infrastructure relating to offshore wind farms and consider ways to minimise the damage to precious inland areas." They added: "We already do this for onshore wind farms through 'Community Benefit Funds', and we were planning something similar for fracking.
The Danish wind power firm Ørsted has warned that up to 10 of its giant offshore windfarms around the UK and Europe will need urgent repairs because their subsea cables have been eroded by rocks on the seabed. ...Ørsted has found that the rocks placed at the base of the wind turbine foundations to prevent the erosion of the seabed were responsible for wearing down the cable protection system which, in a worst case scenario, could cause the cables to fail.
EDF Renewables development manager Dave Sweenie, who has been working on the Neart na Gaoithe (NnG) wind farm for more than a decade, said if projects begin to ramp up at the same time, limited infrastructure could cause bottlenecks to occur. When other industries are thrown into the mix, ports will begin to fill up “very quickly”, creating a “real barrier” for offshore wind deployment, Mr Sweenie warned.
Melanie Austen, Professor of Ocean and Society at Plymouth University, said: ‘We’re talking about effectively urbanising the sea by introducing these structures. Introducing hard structure through cables and the turbines themselves is going to change the ecology and the ecosystem.’
RSPB Scotland has welcomed the new research, with the charity hopeful it will accurately expose the dangers of offshore windfarms to wildlife for the first time. North anti-windfarm protesters, however, claim the commissioning of the study is “too little, too late”. The 11-turbine Aberdeen Bay Wind Farm is already operating, while two of the largest offshore wind projects in the world ...are under construction.
This important analysis by Professor Gordon Hughes of the School of Economics at University of Edinburgh highlights the true costs of wind energy, including offshore wind. He shows how offshore wind costs can be expected to rise, not fall and explains that current estimates of costs are highly optimistic and based on an expectation that costs will drop. A portion of Prof. Hughes' report can be found below. The full report can be accessed at the document links on this page.
Ms Lumley and marine conservation groups fear that more whales and dolphins could be harmed after Boris Johnson promised to ramp up the UK’s offshore wind capacity and are calling for less harmful methods to be used. There is limited data on the impact of exploding ordnance in the sea, but a 2015 study on one area of the North Sea suggested 88 explosions had “very likely” caused permanent hearing loss in 1,280 Harbour Porpoises.
“Not only are there huge engineering and technical challenges but there’s just a huge mobilisation challenge for the industry to get up and running. “One of the biggest obstacles that we all face at the moment is establishing that framework of different policies to enable that rapid growth, because it has to be swift.” Mr Torr explained another challenge lies in driving down the cost of developments in order to make them more competitive.
For all the invocations of harnessing our gusty shores in some ‘green revolution’, the proclamations do not stand up to scrutiny. Even if we cranked up wind power provision to the level the Prime Minister proposes (40 gigawatts), this amount would power only about half the homes in Britain - or 7 percent of the total national energy demand.
