Re: Basic errors?
Wind farms have been around for some time. Much longer than 10 years. I was down Cambridge and there was a cluster of turbines running there - small farm powering the site. Can't recall what it was called, but I passed it most days while I was down there.
America and Japan have also been investing in Wind farms for some time, back to the 80's as I recall.
As to the physics: Wind farms are known to have a localised effect on temperature and weather certainly back into the 90's. Operators have noted the difference although it was not 'studied' scientifically. A lot of knowledge isn't accepted until the scientists have been at it to quantify and qualify and explain it all away. But that's just science for you.
Now, wind turbines do cause turbulence in the air flow. Basic physics - wind is hitting the blade forces the blade to turn but also deflects the wind which then collides with other air flow, causing the turbulence. It settles down again, yes, but the turbulence extends several meters past the blades and out further from the blades than the diameter of the turbine. If you want to see how it works, you can stick a propeller blade into flowing water and watch the turbulence form behind the propeller. It's the same principal, just a different medium.
That the turbines are also warmer than the surrounding air (friction from turning and the flexing of the blades) means you'll get warming in the area. Again, this gets balanced out eventually, but locally you have a 'warm' spot form. People who have been running turbines have known about this for years. Scientists have only just gone and taken a look.
So yes, the physics does hold up. What's more, the only thing 'new' is that scientists have started taking a look and reported it's happening.
