The analysis of almost 3,000 onshore wind turbines — the biggest study of its kind —warns that they will continue to generate electricity effectively for just 12 to 15 years. The wind energy industry and the Government base all their calculations on turbines enjoying a lifespan of 20 to 25 years.
It’s suspected that lower frequency noises make the robin singer “sound” bigger and thus reduce the need for more direct physical encounters to defend their territory. But with the low frequency sound emitted by wind turbines drowning them out, there was a suggestion that robins were having to rely more on puffing out their red chest to deter aggressors.
The Renewable Energy Foundation published this research paper by Dr Gordon Hughes, Professor of Economics at the University of Edinburgh, on the performance over time of wind farms in the United Kingdom and Denmark. The paper can be downloaded by clicking on the link(s) on this page. The UK and Danish data used in the analysis is also available below. The following summarises the results of the research.
This will increase the length of the blades from 41 to 43.5 metres and tip height from 111 to 113.5 metres. The company says this will improve energy yield by around 7 per cent. However, Mappleton Parish Council has objected to the plans, expressing concerns about the potential increase in noise pollution.
The firm believes the spot would be ideal for generating environmentally-friendly electricity, but objectors have argued it will have a negative impact on the natural environment and goes against Aberdeenshire Council’s local development plan.
Historical enemies are uniting to protest against the building of massive wind turbines near the site of the battle of Agincourt. Parties from both sides of the channel have moved to condemn the idea of having the 500ft structures looming over the site of one of Britain’s most indelible victories ever.
Caithness is being "trashed" by turbines, according to an anti-wind-farm campaigner who is opposed to three new projects planned for the county. Brenda Herrick insists the far north has "more than its share" of wind farms and is past its saturation point.
Proposals for the £8m development, consisting of seven turbines up to 132m tall at Barrel Law, near Roberton, were thrown out by Scottish Borders Council’s planning committee in September. German-based ABO Wind has now submitted an appeal to Holyrood’s planning and environmental appeals division.
Once these wind turbines reach the end of their limited lifespan, the challenge is how to continue using the structures, which are often costly to build. ...reusing the foundation generally requires more construction materials and disturbs the soil as much as a new foundation, meaning it is necessary to weigh the benefit of having turbines that can generate more power against the possible land disturbance they can cause.
A second proposed extension of one of Moray’s largest wind farms has been described as a “nail in the coffin” for the region’s tourist industry. Initial plans have been lodged with the Scottish Government to expand the Berry Burn development south of Forres.
A controversial offshore windfarm which will provide power for thousands of homes could be rubber-stamped by planners next week.
Dumfries and Galloway Council rejected the 12-turbine Hopsrig project near Langholm. It concluded that the impact on the setting in the Eskdale valley meant the scheme should not proceed.
Hundreds of people have signed a petition against plans for a major windfarm near Penpont. Sanquhar II Community Windfarm would see 50 turbines built on the site, designed to extend the existing development to the north.
This small increase was reflected in its power generation figures, as renewables produced 6.2TWh between 1 January and 30 September in 2017, and 6.3TWh this year. However, Innogy explained that "particularly low wind levels, especially in the second and third quarters of 2018 in the UK and Germany, led to reduced utilisation of existing plants".
Fred Olsen Renewables wants to build seven new turbines, six of which will be nearly 500ft tall, at Paul’s Hill near Knockando. ...members of Moray Council’s planning committee unanimously agreed to write to ministers to object to the plans due to the impact they would have on the local environment.
Since 2015 there has been a steady erosion of this policy framework: energy efficiency spending has been cut, the cheapest forms of renewables have been locked out of the CfD auctions, support for small scale renewables has been slashed, and plans for renewable heat, new nuclear, and CCS have edged forward at the most glacial of paces.
Study coauthor Professor Maria Thaker said: 'We have known from many studies that wind farms affect birds and bats. 'They kill them and disrupt their movement. But we took that one step further and discovered that it affects lizards too. 'Every time a top predator is removed or added, unexpected effects trickle through the ecosystem.
More than 60 wind farms – most in Scotland – were compensated on October 8. The payouts topped the previous high of £3.4million, sparking fresh criticism of the Scottish Government’s ‘green’ agenda. In very windy conditions, the National Grid cannot cope with the extra energy turbines produce, so firms get ‘constraint payments’ to temporarily shut them down.
A contractor for a major Moray Firth windfarm project has been accused of shutting out UK workers in favour of “cheap foreign labour”. Contracts seen by Energy Voice indicate a number of non-EU nationals on Seaway Heavy Lifting’s (SHL’s) Stanislav Yudin crane vessel have been earning below the national minimum wage.
Workers hired to build the flagship £2.6bn Beatrice offshore windfarm in Scotland have included migrants without proper immigration documents paid a fraction of the UK minimum wage, the Guardian can reveal.
