What is the most common misconception you have about wind turbines?


There are many common misconceptions among people about wind energy and horizontal axis wind turbines. In this article, we will talk about the most common misconception people take as a fact and pass on among themselves.

 

The First Misconception is Blades being not Recycling

Many people and exactly those who are against the idea of wind energy are asking what happens to those huge blades of wind turbines after their working lives are over? Many in the renewable energy industry are looking to turn the potential landfill problem into a profitable recycling opportunity.
The reason is that the first generation wind turbines used since the 1980s are currently being replaced by newer types. Some old wind turbines can be renewed and installed elsewhere. Most of these turbines have components made from precious metals and are easy to recycle if the machine is beyond repair. But the biggest concern is plastic, carbon fiber, and petroleum-based compounds in the blades – because the size of the blades that are disposed of will increase in the coming years.
 
Washington State University has joined Global Fiberglass Solutions, an American company in Washington State, to recycle disassembled turbine blades by dismantling them, into new composite materials that have a variety of commercial and industrial uses.
 
European institutions are also looking for solutions. The German recycling plant  Zagons Logistic It is currently the only factory operating in the world – by recycling blades into cement materials. 
 
Nearly 80 percent of disassembled old wind turbines are sold for reuse elsewhere, but that will change with the demolition of existing wind farms Their blades are not as solid as newer and will need recycling.  The National Science Foundation donated approximately  2 million Dollars to universities in Massachusetts and Kansas to develop biodegradable materials from sustainable sources to manufacture turbine blades. If the idea succeeds, there will be nothing to oppose the use of wind turbines, and there will not be room for opponents, and then truly environmentally friendly wind turbines will emerge.

 

The Second Misconceptions is Wind Turbines kill Birds and Bats

  death of birds

 
 

For many of us, wind power, a feasible source of energy that costs far less than nuclear and coal power, and contributes almost no pollution to the atmosphere, seems almost perfect. 

But there are some people who disagree and are fighting to install new wind turbines in the U.S.
They cite bird mortality as an unacceptable wind-generated side effect. We intend to save large numbers of birds from death at the blades of enormous wind turbines through litigation and demonstrations against the pending legislation.

In the United States, five billion birds are killed annually from anthropogenic sources, including collisions with human-made structures such as vehicles, buildings and windows, power lines, communications towers, and wind turbines; electrocutions; oil spills and other contaminants; pesticides; cat predation; and commercial by-catch fishing.

 

13.7 Million Birds Are Dying Every Day in the U.S

Biologist Melanie Driscoll, of the National Audubon Society, reports that in the United States, a whopping 5 billion birds die every year — about 13.7 million birds die each day. 


The causes of these deaths, of course, are varied; according to a government-led study, millions of birds die of ‘natural’ causes, but there are plenty of factors that keep them from that demise, many of which are near to home. One report indicates that rural cats kill as many as 39 million birds a year in the US alone.

Human activity, however, remains the leading cause of death for birds. 

According to a New York Times article :

 

  • Pesticides kill 72 million birds directly.
  • 60 million to 80 birds killed by cars.
  • High-tension transmission and power distribution lines are also deadly obstacles.

1  billion birds killed  by collision with Buildings each year in the US 

 

Scientists estimate that at least 100 million and perhaps as much as a billion birds die each year in the US when they collide with buildings, particularly skyscrapers covered with glass or illuminated. And, in a new report, conservationists now have a better idea of which American cities are the most deadly for the wings.

European studies; According to fish and wildlife service :

  • 174 million birds die each year by flying into these wires.

 

Only 10,000 to  40,000 birds  killed by wind turbines according  to ABC 

 
The number of birds killed by collision with wind turbines is incomparable with other numbers. So when we read the statistics of wildlife organizations like fish and wildlife showing that Collisions with wind turbines account for about one-tenth of a percent of all « unnatural » bird deaths in the United States each year. And of all bird deaths, 30 percent are due to natural causes, like baby birds falling from nests.

So why the misconceptions that label wind turbines? So why is all this objection even though we do not see a negative impact of the turbines on wildlife, nature, and the climate as well, and in return, we see the great negative impact of other energies on the environment and on the lives of wild and marine species 

So what we conclude is  Wind energy and birds: The two can co-exist, but only if turbines are sited properly we agree with this point and birds protectins services are working with wind turbine companies eliminate threats” and “conserve habitats.” and we should not forget also the advantages of these machines.
