The Wind Farm Scam

Wind_farm_scam_ai_thumb In a book released today, Dr. John Etherington - former Reader in Ecology, Thomas Huxley Medallist at the Royal College of Science and former co-editor of the Journal of Ecology - argues that wind farm technology is a wholly counter-productive and undesirable response to the problems of climate change and electricity generation.

A conservation framework for golden eagles: implications for their conservation and management in Scotland

Snh-report_no193_thumb This report presents a highly important contribution to the conservation of golden eagles in Europe. A penetrating analysis of data from all golden eagle territories in Scotland has yielded a clear picture of the constraints on this bird. In particular, the sustained persecution of golden eagles in some areas and the consequences of heavy grazing pressure in the west are significant issues which must be addressed to allow golden eagles to attain favourable conservation status. The main findings of the report are presented below. The full report can be accessed by selecting the links on this page.

Wind turbines, flicker, and photosensitive epilepsy: Characterizing the flashing that may precipitate seizures and optimizing guidelines to prevent them

186changeappendix3_thumb Wind turbines are known to produce shadow flicker by interruption of sunlight by the turbine blades. Known parameters of the seizure provoking effect of flicker, i.e., contrast, frequency, mark-space ratio, retinal area stimulated and percentage of visual cortex involved were applied to wind turbine features. The proportion of patients affected by viewing wind turbines expressed as distance in multiples of the hub height of the turbine showed that seizure risk does not decrease significantly until the distance exceeds 100 times the hub height. Since risk does not diminish with viewing distance, flash frequency is therefore the critical factor and should be kept to a maximum of three per second, i.e., sixty revolutions per minute for a three-bladed turbine. On wind farms the shadows cast by one turbine on another should not be viewable by the public if the cumulative flash rate exceeds three per second. Turbine blades should not be reflective.

Jane Davis wind turbine noise log

Daviswindturbinelog_thumb Jane Davis of the UK tracked problems with noise from a wind farm located 930 meters from her home. Her daily log, accessed by clicking on the link below, covers the period from summer 2006 to summer 2007. She and her family have since abandoned their home due to health issues related to the noise.

Noise pollution from wind turbines

Noisepollutionfromturbinesdavis_thumb Julian and Jane Davis reside on a farm in the Fens in Lincolnshire England. Shortly following the construction of a wind farm within 1000 meters of their home they had started to hear the noise of the turbines. This important paper, presented at the Wind Turbine Noise conference Sep 20-21, 2007, in Lyon, France, documents the “devastating effects of wind turbine noise pollution when wind farms are sited too close to homes or otherwise inappropriately sited.”

Government statement regarding the findings of the Salford University report

0707governments%c5%a0amreport-2-_thumb Based on these findings, Government does not consider there to be a compelling case for further work into AM and will not carry out any further research at this time; however it will continue to keep the issue under review. Government continues to support the approach set out in Planning Policy Statement (PPS) 22 - Renewable Energy. This approach is for local planning authorities to "ensure that renewable energy developments have been located and designed in such a way to minimise increases in ambient noise levels", through the use of the 1997 report by ETSU to assess and rate noise from wind energy developments.

The Visual Issue - An Investigation into the Techniques and Methodology used in Windfarm Computer Visualisations

The_20visual_20issue_thumb This document does not question whether we should be developing windfarms or should not be developing windfarms, or even whether they look good on a landscape or are a visual intrusion on the landscape. We are simply addressing the methodology used by the windfarm industry, who in our opinion, have been using misleading methods for the last 11 years whilst seeking to obtain planning permission. Having had more than 15 years experience in producing visualisations for planning applications, both here and in other parts of the world, what we see happening throughout Scotland and the rest of the UK is a method of visual presentation which brings our profession into disrepute. After many years of fighting for fairer standards, something has to be done because of the growing public perception that photomontage is unreliable.

Noise Radiation from Wind Turbines Installed Near Homes: Effects on Health

Wtnoisehealth_thumb The important paper reviews research articles within the field of acoustics concerning the acoustic properties of wind turbines and noise and recommends a safe buffer zone of at least 2 km between turbines and residential dwellings.

UK Renewable Energy Data: Issue 1 (08.12.06): Vol. 5: Wind

Uk_renewable_energy_data_thumb Editor's Note: The following are selected excerpts from the Renewable Energy Foundation press release describing this research. The full press release is available via the link below. Using the new research it is now possible to assess how renewable generators up and down the country are performing. This data, published in five online files; Biomass, Hydro, Landfill Gas, Sewage Gas and Windpower, shows that firm generators are producing high load factors with carefully designed resource use and load following. However in the wind sector, far and away the most active of all the technologies at present, results vary enormously due to location. The capacities offshore are encouraging, whilst those onshore are generally only superior in locations very distant from the populations requiring the electrical energy. Although most sites were built on expected capacity factors of around 30%, results include; 19% (approx) capacity factor for the wind turbines at Dagenham, Essex. 9% (approx) capacity factor at the Barnard Castle plant, County Durham. The best performing wind sites are in the north of Scotland, and on Shetland the wind turbines are producing capacity factors of over 50%. Using this analysis of the Ofgem data, researchers have also calibrated a model predicting how a large installed capacity of wind power built across the UK would actually perform. The project used Meteorological Office data to model output for every hour of every January from 1994-2006. The startling results show that, even when distributed UK wide, the output is still highly volatile. The average January power variation over the last 12 years is 94% of installed capacity. It is an uncontrolled variation decided by the weather. The average minimum output is only 3.7% or 0.9GW in a 25GW system. Power swings of 70% in 30 hours are the norm in January. The governments’ expectation is that three quarters of the 2010 renewables target, and the lion’s share of the ‘20% by 2020’ target will be made up of windpower.[2] However, the new research offers predictions which are in keeping with Danish and German empirical experience and demonstrate the need for a broader spread of investment in the renewable sector. The report was commissioned from Oswald Consultancy Limited and funded by donation from the green entrepreneur Vincent Tchenguiz. Campbell Dunford, CEO of REF, said: “This important modelling exercise shows that even with best efforts a large wind carpet in the UK would have a low capacity credit, and be a real handful to manage. This isn’t the best way to encourage China and India to move towards the low-carbon economy. As a matter of urgency, for the planet’s sake, we need to bring forward a much broader range of low carbon generating technologies, including the full sweep of renewables. Wind has a place, but it must not be allowed to squeeze out other technologies that have more to offer.”

Mynydd-y-Gwrhyd Planning Inspector's Report

Gwrhyd_appeal_thumb This is the report submitted by the Planning Inspector appointed by the National Assembly for Wales that dismisses the appeal by the Awe Amman Tawe quango for a wind farm on Mynydd-y-Gwrhyd. Of particular interest are the Inspector's remarks on Landscape and Visual Impact (paragraphs 16-20 on pages 5-6) with respect to how 'developers photomontages' do not give the true visual impact of actual wind farm sites.
