Fiddling Wind Turbine Images

I had to smile when I read a comment from a local windy on one of my posts accusing the local action group (DART) of inflating turbine image size on one of their flyers. ( Comment 5 on this post )

Here is part of what the windy's comment:

I've seen the leaflets that DART circulated, with an image of turbines we estimated were 4 times bigger than the proposed ones. Who wouldn't be horrified by that and sign a petition?

Yes. I agree. But actually, I would bet that what the windy really meant was 4 times bigger than the propaganda images produced by their beloved developer .

As reported in ( This Article ), a prominent Scottish architect along with Stirling University has been conducting research into how various wind farm developers have been cleverly fiddling images to make their wind farms appear less intrusive.

Take these two example images taken from the same location (see the above article) that show the deception. Notice both images are the same width and you can see all of both images.


The top image uses a wide angle lens to give a panoramic view that is well outside the real  field of view of an observer. This is then presented as an image at close range, so then all of the panorama is seen by the observer. The consequence is that the turbines (and buildings for that matter) are reduced and appear much less consequential than in reality. The bottom image shows the view more realistically with a field of view similar to that of a real observer.

There are rules governing these photo montages, but there are loopholes. These loopholes are ruthlessly exploited by the carpet baggers, leading to results similar to that achieved in the top image.

Now, when I look at the example images above, to me, it looks like the bogus pro-wind like propaganda image presents the turbines at about a quarter size of the more realistic bottom photograph.

I don't know if the DART flyer actually did present the turbines a four times larger than the Infinergy images. I didn't see it. But if they did it looks like DART probably got it about right.

So maybe, in the future, perhaps my windie commentator should do as they suggested and "be horrified and sign the petition".

You know it makes sense.

Wind Turbines: The 30% Capacity Factor Myth


I don't know about you, but I am getting really tired of large corporate bodies continually peddling half-truths and even outright lies in order to service their own greed.

Take the wind industry for example. Especially with the way they try to big up the ludicrous ineffectiveness of their money machines.

Truly, if it was not for the fact that they get paid (at least) twice for their intermittent and unreliable production of electricity, these ugly white elephants would be abandoned and left to rot.

Whenever the wind industry talks about the capacity factor (that's the actual averaged output over a year compared to the maximum turbine rating) the wind industry always try and pretend that this capacity factor is 30%.

While this may sound low, it is actually a massive exaggeration on the real figures.

Unfortunately, the wind industry have repeated the lie so many times it is often taken as" a given" by organisations that should know better.

So what is the capacity factor for on-shore wind turbines?

Luckily there are people like Professor Michael Jefferson who has has done an analysis of the exaggerated claims of the wind industry.

His presentation is available Here

While his presentation truly demolishes the mythical 30%, it is just one of the many false claims he debunks. His presentation is well worth a read.

Look at this for 2009: (taken from Professor Jeffersons presentation)


In 2009, the real capacity factor for on-shore turbines was 21% NOT 30% Only 7.5% achieved the mythical 30% capacity factor. In other words 92.5% of on-shore turbines in 2009 failed to reach the 30% capacity factor that is promoted by the wind industry. Remember, since 2009, it has got even less windy.

Even in 2008, which was an abnormally windy year,  over 81% of on-shore turbines failed to chalk up a  30% capacity factor. In fact in 2008, the windiest year in recent history, the real on-shore average capacity factor was 23%.

So when is the wind industry going to stop telling lies?
When are they going to confess that the real output from these monstrous money making machines is much less then the figures they ritually push?

If you are waiting for the truth from the wind industry, I wouldn't hold your breath.

But even this farcically low capacity factor hides the true hideously ineffectiveness of these white elephants.

Always remember when comparing capacity factors of generating equipment that wind power is intermittent. With wind, most of the energy arrives in infrequent, irregular and unpredictable bursts. Most of the time their actual output is much less than even the real dismally low capacity factor.

But more on this in a future post.
