David Mackay - off shore turbine 'wind wakes'
Something that the press need to highlight and ‘central government’ to take note of!!

This is interesting - on David Mackay's own website. Let's hope he tells Ed Miliband BEFORE they put up thousands of off-shore turbines!
Oh, and you wonder how sea-birds negotiate through the turbines in such poor visibility.

Wind farm wakes
I'd like to highlight a stunning photograph and an interesting paper.
The paper, Wake effects at Horns Rev and their influence on energy production, by Mechali, Barthelmie, Frandsen, Jensen, and Rethore, describes measurements of the effects of these wakes on wind power production.
The message of the paper is interesting. The downstream wind turbines lose 20% or 30% of their power, and sometimes even more, relative to the front row. The spacing of the turbines is 7 diameters.
