Problems With Industrial Wind Farms!

The noise impact from wind turbines comes from two sources, in the rotation of the gears and bearings of the turbines and in relation to the swoosh of the turbine blades as the pass the support column of the turbine.  The second feature is a very low frequency sound, which is called infra-sound. Infra-sound is noise whose frequency is too low to be easily audible. Modern wind turbines produce a large amount of it, and as they continue to grow larger they produce more of it.  Low frequency noise has the potential to cause a number of health issues.
The following is a brief outline of some of the issues and concerns with relation to large scale industrial wind turbines.

Noise:

The noise impact from wind turbines comes from two sources, in the rotation of the gears and bearings of the turbines and in relation to the swoosh of the turbine blades as the pass the support column of the turbine.  The second feature is a very low frequency sound, which is called infra-sound. Infra-sound is noise whose frequency is too low to be easily audible. Modern wind turbines produce a large amount of it, and as they continue to grow larger they produce more of it.  Low frequency noise has the potential to cause a number of health issues.

The surrounding wind speed and direction affect the distance and which noise travels as does relative humidity. So on a cloudy day the loudness of acoustic waves (pattern of sound) increases along with the distance it travels. Landscapes also affect sound.  Echo effects from hills, valleys and vegetation make it impossible to predict the pathway of noise.  A home half a mile away may be unaffected by noise on a certain day with the wind coming from a particular direction but a home five miles away may be severally impacted.

Vibration Problems:

A moderate size turbine (5.3mw) weighs about 160 tons, with a blade weighing seven ton, rotating at 180mph on the outside (tip). Industrial turbines that may be situated on flat terrain will need approximately 1,000 tons of concrete to anchor them to the ground.  Element Green Power and Mainstream Energy with the backing of the Irish government is proposing 2,450 industrial turbines that is a total 151,000 truckloads of concrete. It is not hard to imagine that this would not have effect on aquifers and river networks within the area and elsewhere.

Your Home AM/FM Sound:

Unlike other industrial noise the sound from industrial wind turbines is different and is more difficult to ignore.  The reason for this is because the pitch and loudness of the noise varies e.g. like fire engine siren or a police car siren. As wave frequencies decrease the effectiveness of walls and windows to reduce sound is diminished.  In reality windows and walls have a tendency to vibrate at lower frequency. Decreasing wave frequency (is the number of wave peaks [sound] which pass through a point in space) is the same as increasing wavelengths (is the strength of that sound and the distance it travels between sounds).  So when wave lengths (sounds) hit your walls and windows the sound increases leaving the resulting sound in your home becoming louder.

Health and Noise:fdsfdsfsdf

As frequency decreases (infra-sound) there is many effects to health i.e. children with low concentration levels at school, people with asthma having problems with the shadow flicker, sleep disruption, stress, anxiety, migraine, rapid heartbeat (tachycardia) tinnitus (ringing in the ear), and many other vestibular disorders (part of the inner ear and brain that controls and processes balance and eye movement) such as vertigo, motion sickness and balance issues.

Ground Water and Soil Contamination:

Wind turbines are industrial structures. Wind turbines contain gallons of oil and other fluid, industrial farms -- thousands of gallons. Lubricants and coolants are contained not only in the massive blades and body but also in the electric transformers.  There is a very high risk that the fluids could leek and that the surrounding rivers, streams and ground water may be contaminated.

Biodiversity and Wildlife:

Birds and Bats – turbines blades can rotate at high speeds (300km/h), this can be very dangerous as they can get caught by the blades, which may cause loss of flight control and ability to avoid hazard. Their also can be loss of habitat and the food chain may be disrupted for example the -- Otter, Pine Martin, Red Squirrel, which could die due to lack of food. The intrusion of low frequency and infra sound into their habitat for most animals may upset their ability for tracking/defence mechanisms and they may leave the area.  Soil erosion from road construction and de-forestation may occur. Forests may be destroyed as many wind turbines have gone on fire in the past Wind Turbines (see Detailed Accident List compiled by “Caithness Windfarm Information Forum 2013”on our links page.

About 600,000 bats are estimated to have been killed by wind farms in the US in 2012.


Property De-valuation & Community Effects:

When large scale Industrial wind turbines are built in your community they have many negative effects to your life, community and your property.  Firstly your property will be de-valued.  Construction and transport of industrial wind turbines would require widening of public roads, round–about junctions to be re-scaled/re-built along with clearing of hedgerows and the damaging of bye roads just so that they can be built. Along with that there is the extra cost to the local county council for maintaining these roads due to the much heavier loads/traffic in order to maintain these massive industrial wind turbines.

Tourism & Our Heritage:

Our tourism industry in the midlands would also be affected. People like to come to the midlands for the beautiful lakes, fishing, walks-tails and water sports attached to them. The hills and overall landscape would be destroyed.  The hill of Uisneach (182m tall) is known as the traditional centre of Ireland and it is unique in the fact that you can see twenty two counties from the top (two-thirds of Ireland). In medieval times the hill was the main site for the bonfire of the “Beltaine Festival” which signified the beginning of Summer (1st May). So, if the Governments plan for increased wind energy is not stopped when standing on the hill of Uisneach and you look all around, all you will see is massive industrial turbines by day and flickering strobe lights by night.  The same would apply for the Hill of Tara—turbines day and night.
