Just south from Crookwell (approx. 50Kms north of Goulburn) there is a wind farm.
It is located right on top of the Great Dividing Range, and as the sign politely says, it is located here because Crookwell has clean air. I think they mean that this place is as "windy as hell".
These devices are very large, and they looked like they were just a few hundred metres away, but, without anything else to give them a scale, it is hard to tell. They might have been 500 metres away, or more.The point about the distance away is that I could hear absolutely no noise from these wind turbines. I have seen these devices previously, in Germany, and one could hear a quiet "whoosh" as the turbines rotated. But it does not seem to me to be too noisy, or intrusive.
No doubt the sign is a PR statement for wind energy (and Eraring), but I feel this form of energy is less intrusive on the Environment than the coal powered Power Stations run by Eraring Energy. It surely will help minimise Global Warming is we have more of these Wind Power generators.
Here is a chart about how much energy is produced, depending upon the strength of the wind (obviously). There is a cut-out mechanism to prevent damage to the turbines in ultra high wind conditions (as it would be there tonight).
