1. How big are the turbines proposed for the windfarm?
We are looking at turbines up to 125m to blade tip, but the landscape and visual assessment will determine what height of turbines we will use at the site.
2. How many turbines are proposed?
As yet we have not finalised a layout, as environmental and technical studies are ongoing. The results of these studies will determine how many turbines we can locate on the site. We are currently assuming that we will be able to locate up to 5 turbines.
3. What are the wind turbines made of?
The proposed towers are tapered, tubular and made of steel, painted white or light grey. The blades are made of fibreglass-reinforced epoxy. Turbines are usually light grey because this is the colour which is most inconspicuous under most lighting conditions. The finish is matt, to reduce reflected light.
4. How strong does the wind have to blow for the wind turbines to work?
Wind turbines start operating in only a gentle breeze and reach maximum power output after 12 meters/second (around 27 miles per hour). At wind speeds of about 60 miles per hour the wind turbines choose to shut down to avoid damage.
5. What is the lifespan of this project?
Windfarms normally receive planning permission for 25 years, and after this we would need to re-apply for planning permission, or decommission the site and return the land it to its former state. Any consent will certainly contain decommissioning requirements which usually require all visible traces of the windfarm to be removed.
6. Isn't wind power really expensive?
No. Onshore wind energy is actually one of the cheapest of the renewable energy technologies. Wind power can now produce electricity at a cheaper price than nuclear power in the UK and, depending on the oil price, cheaper than fossil fuels. Energy from the wind will become even cheaper in the future as the technology develops. The fuel will remain free.
An average for a new onshore windfarm in a good location is 3-4 pence per unit, competitive with new coal (2.5-4.5p) and cheaper than new nuclear (4-7p) (source: BWEA). Studies from Germany, Denmark and Spain also show that wind power helps to bring the wholesale price of electricity down in the long term because the running costs are close to zero.
7. Why do we need windfarms?
In 2000 the Government set a target of 10% of electricity supply from renewable energy by 2010, and in 2006 announced their aspiration to double that level by 2020 (source: BERR). In 2007, only 5% of the UK's electricity supply came from renewable sources, so we still have a long way to go.
We need to become more energy efficient and reduce our energy consumption, but however much we improve this we will still need to generate electricity. It is important that this electricity is generated from a sustainable source and wind energy is the most proven of all renewable energy technologies.
8. Will this project destroy the landscape?
The development of a windfarm will change the landscape of the area, but this is not necessarily a negative change. This ultimately depends on your personal opinion of the turbines and your acceptance of them as providers of green electricity. We work with professional Landscape Consultants to limit the visual interference from wind turbines.
A landscape and visual assessment of proposed developments will examine the impact of the proposed windfarm on the character of the landscape. Photomontages will be prepared from key views to show how the wind turbines would look in the landscape. Register and we will let you know when these have been added to the website.
9. Are wind turbines noisy?
It is possible to stand underneath a turbine and hold a conversation without having to raise your voice. The evolution of windfarm technology over the past decade means that mechanical noise from turbines is almost undetectable, with the main sound being the aerodynamic swoosh of the blades passing the tower; noise levels from windfarms are on a par with rural background noise. Turbine blades rotate faster when the wind speed is high, and any increase in noise from the turbines would be masked by the increase in background noise (the sound of the wind blowing, trees rustling, etc).
It should also be noted that the method of predicting noise levels assumes an absolute worst case scenario (i.e. the noise from all of the turbines being blown towards all of the monitoring points simultaneously, all of the time), a situation which is unlikely to ever occur.
Any planning permission for a windfarm would contain a planning condition to ensure that noise levels are controlled to an acceptable level.
10. Do windfarms kill lots of birds?
Well sited windfarms do not pose a significant threat to birds. To date, there have been no major adverse effects on birds associated with windfarms in the UK. An article in the journal ‘Nature' reminds us that the greatest threat to wildlife in the UK is climate change; the RSPB predicts that without a comprehensive network of renewable energy sources, climate change is predicted to detrimentally affect most species within the UK.
11. Do wind turbines frighten livestock?
Wind farming is popular with farmers, because their land can continue to be used for growing crops or grazing livestock. Sheep, cows and horses are not disturbed by wind turbines. The first windfarm built in the UK, Delabole, has a stud farm and riding school, and the farmer, Peter Edwards, often rides around the windfarm on his horse.
12. What about humans? How safe is wind energy?
Wind energy is one of the safest energy technologies and does not produce any emissions, harmful pollutants or waste products. As far as we are aware, no member of the public has ever been injured during the normal operation of a wind turbine, with over 25 years operating experience and with more than 70,000 machines installed around the world.
13. Does wind farming harm tourism?
There is no evidence to suggest that windfarms have a negative effect on tourism. In fact, the opposite is often found to be the case and many developers are asked to provide a visitor centre, viewing platforms and rights of way to their sites. A MORI poll in Scotland carried out in 2002 showed that 80% of tourists would be interested in visiting a windfarm. The UK's first commercial windfarm at Delabole received 350,000 visitors in the first ten years. The turbine at Swaffham in Norfolk enjoys 10,000 visitors a year.
14. Can we get free electricity?
Unfortunately this is not possible. Electricity supply is a regulated industry and current legislation prevents this. Due to the design of the national electrical distribution system it is more efficient for the turbines to be connected into the exisiting grid network, where it will be mixed in with electricity produced by a variety of power generation sources, such as gas and coal fired power stations.
15. What alternatives are there?
There are many existing forms of power generation including, coal-fired, oil-fired, gas-fired and nuclear power stations. In terms of renewable energy, onshore windfarms are more economical to develop; offshore windfarms take longer to build because the sea is inherently a more hostile environment. If offshore windfarms were the only form of wind generation it would make meeting our renewable energy targets very difficult.
At the moment, energy from waves and tides is not really a viable alternative for substantial generation because the technologies are only emerging.
16. Why is there opposition to windfarms?
Local opposition to proposed windfarms usually arises because some people perceive that the development will spoil the landscape that they are used to. Most of the other criticisms made about wind energy today are exaggerated or untrue, and simply reflect attempts to discredit the technology, worry local communities and turn them against renewable energy schemes. Anti-wind groups have able to create highly emotive and divisive reaction in local communities, where sensible discussion of the issues is sometimes forgotten.
Wind energy is one of the most popular energy technologies. Opinion surveys regularly show that just over eight out of ten people are in favour of wind energy, and less than one in ten (around 5%) are against it.
17. What happens when the wind stops blowing?
The grid has to be monitored to keep supply and demand in balance and some standby capacity has to be kept in reserve in case of sudden power generation losses.
On the occasion when the wind does stop blowing, electricity continues to be provided by other forms of generation, such as gas, coal, nuclear and hydro. Our electricity system is very flexible, and is capable of coping with variations in demand and unexpected shutting down of large power stations, many times the size of a windfarm.
18. How long does it take for a turbine to 'pay back' the energy used to manufacture it?
The average windfarm in the UK will pay back the energy used in its manufacture within six to eight months. Over its lifetime a wind turbine will produce over 30 times more energy than was used in its manufacture.
Nuclear fission's payback period is two and a half years, coal power 3.3 years and biomass between two and three years (UK Government, 2004). The payback time for solar photovoltaic systems is between four and nine years depending on location and efficiency (Strathclyde University, 1999).
19. Will building wind turbines help combat global warming?
Windfarms do not emit carbon dioxide and provide clean and renewable energy, unlike power stations, which emit 170 million tonnes of CO2 each year. If we are to meet government targets of cutting these figures 60% by 2050, we need a source of energy that does not produce carbon dioxide.
20. Do windfarms have an effect on house prices?
The Royal Institute of Chartered Surveyors have undertaken studies to assess if there is an affect on the house prices due to the construction of a windfarm. In general the survey shows that the largest drop in house value is at the time of the planning application as is the case with any major development.
The house prices appear to recover after the windfarm has been constructed. Detached houses have been shown to have the most immunity to a decrease in house price.

21. Do wind turbines affect TV reception?
In extremely rare circumstances, some interference to analogue TV reception is possible. The main causes of problems are weak signals that are being received by old or poorly tuned aerials. However this is normally identified pre-construction and can be easily remedied. It should also be remembered that the UK is switching to a digital television signal at present (2009 to 2012), which means that satellite TV, Sky or free-to-air satellite signals from the BBC or ITV are totally unaffected by windfarms as the signal is beamed down from space by satellite.
22. Are wind turbines efficient?
In the UK, wind turbines produce useful power for 70-85% of the time. Measured in terms of mechanical efficiency, a wind turbine is over 40% efficient compared to a coal fired power station at about 38% and a typical internal combustion engine at 20-25%.
23. Is there a law that prohibits turbines to be located within 2km of properties?
No, there is no law that states this. Scottish Planning Policy 6 (SPP6) Annex A provides guidance to be considered in to the formation of planning policy and broad areas of search for onshore windfarm developments over 20MWs in size. The extract reads:
"Broad criteria should be used to set out the considerations that developers should address in relation to local communities. These should ensure that proposal are not permitted if they would have a significant long term detrimental impact on the amenity of people living nearby. When considering spatial policies, planning authorities may consider it helpful to introduce zones around communities as a means of guiding developments to broad areas of search where visual impacts are likely to be less of a constraint. PAN 45 confirms that development of up to 2km is likely to be a prominent feature in an open landscape. The Scottish Ministers would support this as a separation distance between turbines and the edge of cities, towns and villages so long as policies recognise that this approach is being adopted solely as a mechanism for steering proposals to broad areas of search and, within this distance, proposals will continue to be judged on a case-by-case basis."
It is also worth noting that there are operational windfarms in Scotland which have turbines within 2km of settlements/ individual properties.
The equivalent planning guidance document in England, Planning Policy Statement 22, does not refer to separation distances from settlements/properties. Obviously the noise and landscape assessment, specific to this site, will ultimately determine separation distances from properties.
24. Does producing energy from windfarms cost more than gas, coal or nuclear?
Onshore wind energy is actually one of the cheapest of the renewable energy technologies especially when you consider the environmental costs. Energy from the wind is likely to become even cheaper in the future as the technology develops and lets not forget that the wind is free.
In October 2009, OFGEM, the UK energy regulator, published major research (Project Discovery - Energy Market Scenarios) examining four possible energy scenarios to 2020. They concluded that in the longer term electricity prices must increase in real terms, due to our ever increasing reliance upon imported gas from eastern Europe and Russia.
But they found that a strategy to develop low carbon forms of generation (a balanced mix of nuclear and renewables) not only helped to tackle climate change, but was by far the cheapest option for UK consumers - in fact reducing increases by 2/3rds compared with a "dash for energy".
25. Why do we need windfarms?
There are two overriding issues of public interest that are driving the development of windfarms. First, the need to generate electricity without emitting carbon dioxide in order to help tackle climate change and secondly to decrease our dependent upon imported gas and increase energy security.
In 2000 the Government set a target of 10% of electricity supply from renewable energy by 2010. Six years later they doubled that target to 20% with a deadline of 2020 (source: BERR). In 2007, only 5% of the UK's electricity supply came from renewable sources, so we still have a long way to go.
We need to become more energy efficient and reduce our energy consumption, but however much we improve this we will still need to generate electricity. It is important that this electricity is generated from a sustainable source and wind energy is the most proven of all renewable energy technologies.
26. How will this project work with the exisiting landscape?
The development of a windfarm takes into consideration the existing landscape of the area and we work with professional Landscape Consultants to ensure any proposal provides the best possible solution.
This ultimately depends on your personal opinion of the turbines and your acceptance of them as providers of green electricity. A landscape and visual assessment of proposed development will examine the impact of the windfarm on the character of the landscape. Photomontages will be prepared from key views to show how the wind turbines would look in the landscape.
Register your details and we will let you know when these have been added to the website.
27. Will I be able to hear the wind turbines?
It is possible to stand underneath a turbine and hold a conversation without having to raise your voice.
The evolution of windfarm technology over the past decade means that mechanical noise from turbines is almost undetectable, with the main sound being the aerodynamic swoosh of the blades passing the tower; noise levels from windfarms are on a par with rural background noise.
Turbine blades rotate faster when the wind speed is high, and any increase in noise from the turbines would be masked by the increase in background noise (the sound of the wind blowing, trees rustling, etc).
Any planning permission for a windfarm would contain a planning condition to ensure that noise levels are controlled to an acceptable level.
28. What alternatives are there?
There are many existing forms of power generation including, coal-fired, oil-fired, gas-fired and nuclear power stations.
In terms of renewable energy, onshore windfarms are more economical to develop.
Offshore windfarms take longer to build because the sea is inherently a more hostile environment and the planning process more complex. The potential for offshore windfarms are huge but we still have a considerable way to go to fulfil that potential.
At the moment, energy from waves and tides is not really a viable alternative for substantial generation because the technologies are only emerging.
29. What response do you get to windfarm developments?
The views of people near proposed windfarms varies considerably and tend to be more negative than for communities with an existing windfarm.
Independent research by scientists at the University of Saint Andrews (Green on Green, public perceptions of wind power in Scotland and Ireland, Warren et al, Journal of Environmental Planning and Management, Nov 2005) found that 90% of people living near to an existing windfarm were either supportive or strongly supportive of an expansion in wind power and of their local windfarm, while only 70 of those living near to a proposed windfarm were supportive of expansion and only 60% supportive of the proposed windfarm.
The same researchers also examined attitudes in the Mull of Kintyre in 2008 - at the time of the study, the most densely windfarm populated part of the UK (Does community ownership affect public attitudes to wind energy? A case study from south-west Scotland, Warren et al, Land Use Policy, 2009). They found over 70% of the local population supportive or very supportive of further expansion of wind power in their area, with only 7% against. Interestingly, they found that support rose to well over 90% with no opposition if community ownership was an option.
30. What happens when the wind speed reduces?
The national electricity grid has to be monitored to keep supply and demand in balance and some standby capacity has to be kept in reserve to cope with variations in demand and generation across the electricity network.
Our electricity system is very flexible, and is capable of coping with variations in demand and unexpected shutting down of large power stations, many times the size of a windfarm.
On the occasion when the wind resource reduces, electricity continues to be provided by other forms of generation, such as gas, coal, nuclear and hydro.
31. How long does it take for a turbine to 'pay back' the energy used to manufacture it?
The average UK windfarms takes only six months to pay back all the energy used to manufacture, build, operate and decommission the windfarm (Life Cycle Assessment of offshore and onshore sited wind farms. Elsam Engineering, 2004).
Thus, over its lifetime a wind turbine will produce about 30 times more energy than it consumes.
Nuclear fission's payback period is two and a half years, biomass between two and three years (UK Government, 2004) while coal power always uses more energy than it supplies, as it will always require fuel to produce energy.
The payback time for solar photovoltaic systems is between four and nine years depending on location and efficiency (Strathclyde University, 1999).
