This is teh awesome!
“Clouds stream in the wake of wind turbines arrayed at the Horns Rev offshore wind farm in this stunning photo. But David MacKay, a physicist at the University of Cambridge in the UK, sees the image as illustrating the common problem of back-row wind turbines losing power relative to the front row.
Downstream wind turbines may lose 20 percent or even 30 percent of their power compared to their fellows in front, according to a study on wake effects at Horns Rev that MacKay highlights on his blog.”

That is one thing i’ll never understand about the ecoharpies they are continually bleating about “renewable energy”. Yet can’t seem to grasp the concept of Base Load Power. The stuff that we use at work and keeps business running etc.
I’ve given up on their deluded musings, i’d laugh in their faces but it’s too much like kicking a puppy. But slapping them around the head with a fish………i’m ok with that.

Bugger, i forgot to add, that is a DUDE of a photie.

Since the whole point of renewables systems is to increase the available Base Power thus reducing Peak Demand, it’s pretty clear you’ve got a pretty shaky grasp yourself
But yeah, awesome picture

Bullshit james, without subsidies these bits of shit that can’t produce base load wouldn’t exist.

WTF does that even mean?

Wicked photo! I wonder how many birds are “eternaly resting” at the bottom of that little lot?

Hang on just a damn minute here, that looks suspiciously like the pollution generated by nuclear power!
What kind of sick twisted eco vandals have wired up these propellers to a nuclear bomb?

And nuke plants don’t get sabotaged by aliens either.

Love the ominous Terminator soundtrack there, Bing.

It gets better. In the USA the turbines seized up because they do not work well in the snow!!!!

Hi may I enquire of the provinence of the Horns Rev photograph involving the mist please?
Would you have a higher resolution image that I can use in a presentation?
I am trying to protect an aerodrome from the intrusion of wind-farm turbine wake plumes, and this photo apparently shows the nature and extent of the wake plume through what appears to be the generation of condensation when the power is poorly extracted from the air. (Only 35% of the power can be extracted the rest goes to waste – I assume. Turbines in this country are also spun up by applying power so they can “hook” into the wind, I am suprised that hasn’t been mentioned.)
The proponents know that turbines generate turbulence and a wake plume, that the plume consists of a velocity deficit where wind spead can be as low as 1/3 of the free airspeed, so much so that they tend to space them appart so turbine shadowing is less prominant. This photo seems to show just how bad it is to use regular spacing in a wind farm, for from certain angles the wind is synchronised (for want of a better word) and the wake plumes accumulate, which would severly limit their efficiency due to having to feather them to avoid damage from the plumes.
