(archive: 2012) Ten facts about wildlife and windfarms
Say No to Lingo

Wildlife, Wind power, Wind energy

[posted 2012]

1. Birds most at risk from wind turbines have been shown to be birds of prey and waterfowl. Passerines are at slightly lesser risk but are still impacted.

References:  Desholm, M. 2009, Journal of Environmental Management, 90, 2672-2679; Madson & Boertman, 2008, Landscape Ecology, 23, 1007-1011

2. It is not just a simple matter of wind turbines killing birds by collisions because they migrate across the site or nest close to developments. What also matters is the presence of turbines, especially in arrays, located between the roosting, nesting or foraging sites of birds because the turbines form a ‘barrier’ the birds cannot or will not cross.

Reference:  Ferrer et al., 2012. Journal of Applied Ecology, 49, 38-46.

3. Flying over or diverting around wind farms to reach foraging or roosting sites has high energy costs for birds, as the higher or further they fly the greater metabolic demand this imposes on them. This can be critical during the winter when food is scarce and the air temperature is low.

Reference:  Sugimoto et al., 2011. Ornithological Science, 10, 61-71.

4. Grassland birds, such as lapwing that forage on the ground, are mainly impacted by turbines because the turbines prevent or deter their movement between forage and roost sites.

Reference:  Pruett, et al., 2009. Bioscience, 59, 257-262.

5. An 11-year study of bird mortality in relation to wind farm developments at coastal regions in Northumbria found that between 16 and 21 birds were killed per turbine per year, mainly by collision. Affected species tended to be guillemots, kittiwakes, gulls and pigeons.

Reference:  Newton & Little, 2009, Bird Studies, 56, 158-167.

6. Mortality of raptors from turbines has been found not to correlate with bird abundance. Rather mortality depends on turbine height and elevation above sea level. The taller or higher the turbine the greater the mortality rate.

Reference:  De Lucas et al., 2008. Journal of Applied Ecology, 45, 1695-1703.

7. Male birds tend to be killed more frequently by turbines than females because they spend more time foraging. However, chicks suffer and may die indirectly because they depend on food foraged by males to supplement that obtained by females.

Reference:  Stienen et al., 2008. Condor, 110, 154-157.

8. Some wildlife species, including birds and squirrels, have been shown to suffer stress (as indicated by high alertness behaviour and alarm calling) in the vicinity of wind turbines compared to animals under control (no turbine) conditions. It is well known that prolonged (chronic) exposure to stress reduces fecundity, immunity, growth and longevity in many animal species.

Reference:  Kikuchi, 2008. Journal for Nature Conservation, 16, 44-55.

9. Poor correlation exists between pre–wind farm development risk assessments and actual post construction recorded deaths. Deaths are often underestimated because carcases attract scavenging birds. These, in turn, are then struck by the blades and die, thus pushing up the overall death count.

Reference:  Smallwood et al., 2010. Journal of Wildlife Management, 74, 1089-1097.

10. Assessment of bird or bat mortality by counting carcases is also unreliable if other scavengers (eg foxes) remove corpses from the area, especially at night, before counting is undertaken. Therefore recorded mortality rates due to collision are probably less than the real death toll.

Reference:  Korner-Nievergelt et al., 2011, Wildlife Biology, 17, 350-363.

Sheldon, N.Y., Council

New York, Ordinances, Wind power, Wind energy

[posted 2006]

The Sheldon ordinance is an example of the author’s very limited understanding of the complexities of industrial wind development. The residents of Sheldon are currently dealing with the consequences of this weak document that offers virtually no protection for their well-being or their local investments.

[posted 2011]

In June 2011, Lincoln Electric erected a wind tower measuring 443 feet tall at its world headquarters and manufacturing campus in Cleveland, Ohio. This installation is the largest known urban wind tower in North America, and is capable of producing 2.5-megawatts of electrical energy, or approximately 10 percent of the requirements for Lincoln Electric’s main Cleveland manufacturing facility. Lincoln Electric officially dedicated its wind tower on August 23, 2011.

How big is the tower? Measures 443 feet tall from the base to the tip of the blade:

How big are the blades? Features 3 blades:

How fast can the blades travel? Blade tip speed is 165 mph at a hub rotation of 14.1 rpm

What are the dimensions of the base?

Hawkins, Kent

Denmark, Grid, Wind power, Wind energy

[posted 2010]

According to wind proponents, Denmark is a model of wind energy use for electricity generation to be emulated. It is claimed or suggested that:

These conclusions are superficial at best and invalid at worse. The analysis required to show this, however, is extensive and technical because the Denmark power market is unique and wholly unlike the market in the U.S. or the UK.

(archive: 2014) Wind farms and health: Who is fomenting community anxieties?
Shepherd, Daniel

Health, Wind power, Wind energy

[posted 2014]

TO THE EDITOR: By his deployment of ad hominem arguments, outdated or industry-sponsored research, comparison to an unrelated phenomenon, and a biased selection of case studies and research reports, I fear the pro–wind-industry opinions expressed by Chapman [1] will only serve to exacerbate the psychogenic and sociogenic processes he laments.

Wind turbine noise must be treated like any other source of community noise, and its association with renewable energy must not excuse it from public health guidelines. The emergence of large wind turbines clustered close together in “wind farms” can produce modulated noise exceeding 100 decibels in their immediate vicinity.[2] Such exposure will seriously impact health through sleep disturbance and noise-induced stress.

The issue, then, is to determine reasonable distances from human habitation and noise guidelines, such as those for airports, drinking establishments and motorways. There are no current data indicating that wind-turbine noise is privileged in relation to health impacts. Rather, data not acknowledged by Chapman suggest the opposite.[2-5] Indeed, the only mass hysteria I see comes from wind-farm activists who have an aversion to data and a love of conspiracy theories and voodoo. As a public health researcher, I appeal for more data and less opinion.
