Most of the time when i fly over any wind generators they seem to be stationary. As far as i'm aware the generators that need to take power from the grid are heating the blades and gearboxes in the colder places.
...Anyway, since yesterday the combined 'power' output of all of south eastern Australia's wind generators has not exceeded 15% of potential capacity at any time. What an idiotic power system..
