Hi,

consider the massive pollution caused in the manufacture of the tons of steel & cement, then consider the tons of pollution caused by transport of all this and the massive structure of the Wind Turbine itself and the miles of coppoer wire for the installation & windings of the generator – now consider the infrastructure of roads to service these useless & damaging monstrosities.

Many of the service roads are across & through wonderful open vistas and across ancient moorlands, forests and peat beds.

Then consider the costs and pollution that will be caused cutting up the tons of reinforced steel & concrete & transporting it to landfill sites when the technology becomes obsolete as did wind power in the past.

Just why would anyone be so stupid as to instal wind turbines were it not for the bribes, backhanders and opportunities for the wealthy to milk the subsidies paid by tax payers!

Here is just a quick extract found on TWITTER!

Another Wonderful Whack of the Day comes from that special Constable, John, of the Global Warming Policy Foundation/Renewable Energy Foundation, in a letter to the Scottish Daily Mail.

His truncheon whacks the Scottish Government and Paul Wheelhouse into next week.

Enjoy.

Deaf to worries about these ugly, costly and noisy sites

By John Constable, Energy Editor, Global Warming Policy Forum

There is hardly a Munro left in Scotland from which you cannot see a wind farm. In recent years the landscape has been transformed by enormous turbines.

These structures are more than 100 metres (330ft) in height and when many are clustered together, they are highly visible even from great distances.

People who choose to live in the wild areas of rural Scotland do so for a reason: because they love it. Those who go walking in these places feel the same.

They find them beautiful, and they’re sensitive to the landscape and to visual intrusion. Many are upset by the large number of turbines that have been erected.

Wind farms have a huge impact on the local environment, and not only visually. From surprisingly far distances people can hear them and the noise they make is peculiar and intermittent – it wakes them up at night and they can’t get back to sleep. Wind farms do not make good neighbours.

They are often constructed in areas where there are no roads, meaning these have to be created, sometimes on peat.

This leads to real concerns over the balance of damage and benefit – the benefits of low emissions energy on the one hand, yet the damage to the local environment on the ground, and whether that is really justified.

Almost all of the UK’s wind farming is concentrated in Scotland, because the Scottish Government is not listening to the objections of the residents who have to live near these sites.

Because so much of the Scottish population is concentrated in urban areas, however good the environmental arguments made by local objectors are, there simply aren’t enough voices for the SNP in Edinburgh to care. The simple truth is that this is political statistics.

So it is perhaps not surprising that the Scottish Government’s new energy strategy is planning an expansion of the number of turbines.

The Government has accepted a lot of the spin coming out of the wind farm industry without being sufficiently sceptical. They’ve swallowed it all hook, line and sinker. Energy Minister Paul Wheelhouse continues to say that onshore wind is the lowest-cost form of new generation energy, but this is simply not true.

Onshore wind is generally extremely expensive in comparison to electricity from conventional sources, particularly combined cycle gas turbines.

It is well known that the subsidy and system costs of existing wind farms put them well above the cost of other forms of energy. Subsidies in the UK for renewables in total now come to about £7billion per year.

You’re taking money – in other words, resources – from elsewhere in the economy and giving it to wind generators.

By redirecting resources towards the wind sector, you are suppressing activity in other parts.

So you may have created jobs in the wind sector but how many jobs have you destroyed in other fundamentally economic activities?

The costs for all forms of wind are high. The farms require more grid and special operations of the grid system to keep it balanced. These costs are not small.

When you add it all up, the total cost to the consumer of a unit from a wind farm is considerably higher than that from a conventional generator. So how is the Scottish Government going to pay for these new plans?

In the autumn Budget, the Chancellor said there would be no new subsidies for wind turbines – indeed all renewables – until 2025 at the earliest.

With new sites, wind farm operators will sometimes say they don’t require subsidies, but that remains to be seen.

This suggests to me, then, that the SNP is either hoping for a change in policy, or it is being deliberately vague in its ambitions. Does it believe any of this?

If all these turbines were to be built, the Government faces another problem: an enormous expansion of the grid to serve them. You need an awful lot of wire to get wind from the wind farms to the interconnectors that serve the grid.

As Scotland knows from the controversial Beauly to Denny power line, this is not an easy thing – it’s expensive and ugly – and someone has to pay for it.

A few people may well benefit from the further expansion of wind turbines in Scotland – land owners and wind farm operators, perhaps – but it is unlikely to be the Scottish people.

Nightmare Of Wind Turbine Blade Disposal: 2 New Papers Expose The Environmental Nightmare Of Wind Turbine Blade Disposal

No Tricks Zone
Kenneth Richard
22 June 2017

“If the industry cannot come up with more sustainable manufacturing and disposal processes, public acceptance of wind energy would decline if the public becomes aware of these issues” – Ramirez-Tejeda et al., 2017

Despite an explosion in installed wind capacity since 1990, wind power had achieved just 0.39% of the world’s total energy consumption as of 2013.

Germany has assumed a leading role in promoting the consumption of renewable energy.  And yet even in Germany the share of energy consumption from wind power reached only 2.1% in 2016.

Despite its extremely limited infiltration as a world energy source, it is assumed that a rapid expansion of wind power will ultimately be environmentally advantageous both due to its reputation as a “clean” energy and because of the potential to contribute to reduced CO2 emissions.

Recently, however, the austere environmental impacts and health risks associated with expanding wind energy have received more attention.

For example, scientists have asserted that wind turbines are now the leading cause of multiple mortality events in bats, with 3 to 5 million bats killed by wind turbines every year.   Migratory bats in North America may face the risk of extinction in the next few decades due to wind turbine-related fatalities.

Frick et al., 2017

“Large numbers of migratory bats are killed every year at wind energy facilities. … Using expert elicitation and population projection models, we show that mortality from wind turbines may drastically reduce population size and increase the risk of extinction. For example, the hoary bat population could decline by as much as 90% in the next 50 years if the initial population size is near 2.5 million bats and annual population growth rate is similar to rates estimated for other bat species (λ = 1.01). Our results suggest that wind energy development may pose a substantial threat to migratory bats in North America.”

Wind Turbine Blades Last 20 Years…And Then They Are Tossed Into Landfills

Besides reducing wildlife populations, perhaps one of the most underrated negative side effects of building wind turbines is that they don’t last very long (less than 20 years) before they need to be replaced. And their blades aren’t recyclable. Consequently, 43 million tonnes (47 million tons) of blade waste will be added to the world’s landfills within the next few decades.

Liu and Barlow, 2017

“The blades, one of the most important components in the wind turbines, made with composite, are currently regarded as unrecyclable. With the first wave of early commercial wind turbine installations now approaching their end of life, the problem of blade disposal is just beginning to emerge as a significant factor for the future. … The research indicates that there will be 43 million tonnes of blade waste worldwide by 2050 with China possessing 40% of the waste, Europe 25%, the United States 16% and the rest of the world 19%.”

“Although wind energy is often claimed to provide clean renewable energy without any emissions during operation (U.S. Department of Energy, 2015), a detailed ecological study may indicate otherwise even for this stage. The manufacture stage is energy-intensive and is associated with a range of chemical usage (Song et al., 2009). Disposal at end-of-life must also be considered (Ortegon et al., 2012; Pickering, 2013; Job, 2014).A typical wind turbine (WT) has a foundation, a tower, a nacelle and three blades. The foundation is made from concrete; the tower is made from steel or concrete; the nacelle is made mainly from steel and copper; the blades are made from composite materials (Vestas, 2006; Tremeac and Meunier, 2009; Guezuraga et al., 2012). Considering these materials only, concrete and composites are the most environmentally problematic at end-of-life, since there are currently no established industrial recycling routes for them (Pimenta and Pinho, 2011; Job, 2013).”

In a new paper entitled  “Unsustainable Wind Turbine Blade Disposal Practices in the United States”, Ramirez-Tejeda et al. (2017) further detail the imminent and unresolved nightmare of wind turbine blade disposal. The environmental consequences and health risks are so adverse that the authors warn that if the public learns of this rapidly burgeoning problem, they may be less inclined to favor wind power expansion. Advocates of wind power are said to be “largely ignoring the issue”. It’s an “issue” that will not be going away any time soon.

In light of its minuscule share of worldwide consumption (despite explosive expansion in recent decades), perhaps it is time to at least reconsider both the benefits and the costs of wind energy expansion.

‘Adverse Environmental Consequences’ For A Rapidly Expanding Wind Power Grid

Ramirez-Tejeda et al. (2017)

“Globally, more than seventy thousand wind turbine blades were deployed in 2012 and there were 433 gigawatts (GW) of wind installed capacity worldwide at the end of 2015. Moreover, the United States’ installed wind power capacity will need to increase from 74 GW to 300 GW3 to achieve its 20% wind production goal by 2030. To meet the increasing demand, not only are more blades being manufactured, but also blades of up to 100 meters long are being designed and produced.”

“The wind turbine blades are designed to have a lifespan of about twenty years, after which they would have to be dismantled due to physical degradation or damage beyond repair. Furthermore, constant development of more efficient blades with higher power generation capacity is resulting in blade replacement well before the twenty-year life span.”

“Estimations have suggested that between 330,000 tons/year by 2028 and 418,000 tons/year by 2040 of composite material from blades will need to be disposed worldwide. That would be equivalent to the amount of plastics waste generated by four million people in the United States in 2013. This anticipated increase in blade manufacturing and disposal will likely lead to adverse environmental consequences, as well as potential occupational exposures, especially because available technologies and key economic constraints result in undesirable disposal methods as the only feasible options.”

Problems With Landfills

“Despite its negative consequences, landfilling has so far been the most commonly utilized wind turbine blade disposal method. … Landfilling is especially problematic because its high resistance to heat, sunlight, and moisture means that it will take hundreds of years to degrade in a landfill environment. The wood and other organic material present in the blades would also end up in landfills, potentially releasing methane, a potent greenhouse gas, and other volatile organic compounds to the environment.”

“The estimated cost to put blade material in landfills, not including pretreatment and transportation costs, is approximately US $60 per ton. [A typical blade may weigh 30-40 tons]. In the United Kingdom, where landfilling organics is not yet prohibited, the active waste disposal cost (which includes plastics) is approximately US $130 per ton.”

Problems With Incineration

“Incineration of blades is another disposal method with potential for energy and/or material recovery. … Combustion of GFRP is especially problematic because it can produce toxic gases, smoke, and soot that can harm the environment and humans. Carbon monoxide and formaldehyde have been reported as residue from thermal degradation of epoxy resin. Another residue is carbon dioxide, which poses concerns regarding greenhouse gas emissions. In addition, about 60% of the scrap remains as pollutant ash after the incineration process, some of which is sent to landfills, potentially contaminating the sites. Possible emission of hazardous flue gasses is also among the issues with incinerating wind turbine blades.”

“One key issue is that all these thermal processing techniques for wind turbine blades would also require fragmentation of the material into smaller pieces through mechanical processing before being fed into the reactors, increasing energy consumption and carbon dioxide emissions.”

Problems With Mechanical Processing

“Mechanical processing is a relatively simpler disposal method that consists of cutting, shredding, and grinding the material to separate the fibers from resins, so it can be repurposed. This process is energy intensive and produces small fiber particles with poor mechanical properties that can only be used as filler reinforcement material in the cement or asphalt industries. … The dust emitted in the grinding process of FRP creates occupational health and safety risks for workers. Inhalation, as well as skin and eye contact can produce moderate irritation to mucous membranes, skin, eyes, and coughing. Occupational exposure and prolonged inhalation of such particles have been found to produce alterations of the cellular and enzymatic components of the deep lung in humans, identified as acute alveolitis.”

Problems With Chemical Degradation

“The last method is chemical degradation, which consists of first mechanically reducing the size of the blades, then degrading them using a chemical solution. … Although no industrial-level chemical recycling of thermoset polymers has been done yet, some hazardous chemicals such as nitric acids and paraformaldehyde have been used in testing and development processes. Occupational exposure to these chemicals can produce harmful respiratory diseases including potential nasal cancer, and dermal health effects.”

Advocates Of Wind Power ‘Have Largely Ignored The Issue’

“Few individuals and organizations recognize the problems inherently related to blade recyclability. This situation creates an obstacle for promoting policy interventions to solve these problems. As a result, manufacturers, wind farm operators, and advocates have largely ignored the issue, focusing efforts on promoting wind energy and addressing other issues such as negative impacts on wildlife and noise generation.”

“If the industry cannot come up with more sustainable manufacturing and disposal processes, public acceptance of wind energy would decline if the public becomes aware of these issues, inhibiting its growth as one of the main sources of electricity generation in the United States.”

NoTricksZone

NoTricksZone flatters these things when it puts the lifespan of wind turbine blades at 20 years. The whole unit has an economic life of little more than a decade (see our post here).

Wind turbine blade failure is one of the more common features of these wondrously ‘reliable’ things: Wind Turbine Terror: Spanish Home Hit by Flying Blade – Just 1 of 3,800 Blade ‘Fails’ Every Year

And it’s not uncommon for turbine blades to fail within months of coming into operation.

At AGL’s Hallett 1 (Brown Hill) wind farm, south of Jamestown, South Australia the blades on each and every one of its 45 Suzlon S88s failed within their first year of operation, requiring their wholesale replacement.

The 2.1 MW, Indian built turbines commenced operation in April 2008. Not long into their operation, stress fractures began appearing in the 44m long blades. Suzlon (aka Senvion aka RePower) claimed that there was a “design fault” and was forced by AGL to replace the blades on all 45 turbines, under warranty.

The photos below show the stubs from those blades outside Suzlon’s Jamestown workshop. The main bodies of the blades were ground up and mixed with concrete used in the bases of other turbines erected later (the plastics in the blade are highly toxic, and contain Bisphenol A, which is so dangerous to health that the European Union and Canada have banned it):

Turbine blade failures, including events where 10 tonne blades are thrown to the 4 winds (aka ‘component liberation’) are so common that we are able to finish this post with a graphic documentary, the captions are linked to the stories behind the pictures:

And, we’ll finish with the video that strikes fear into the hearts of those unfortunate enough to live within 2 kms of these things:

Terrifying, dangerous and pointless!

And, it must be comforting to know that the liberated components depicted above (along with 3,800 odd blade fails every year) were quietly dumped in landfills to deliver their toxic cocktail into aquifers and water supplies for centuries to come.
