Wind Farm Statistics

statsHave you ever wondered how efficient you local Renewable Energy factory is? With a certain amount of dogged determination you can extricate the figures but if someone else has done it for you, all the better. To this end I came across a site called Variable Pitch. Seemingly an independent source using a clever bit of software which is now available open source, it provides a wealth of information both on  efficiency and financials that will inform and educate both sides of the argument. Click to access the site. and then explore at your leisure. Certainly one to bookmark. I do have a few minor issues. The chart of power supplies is based not on performance but capacity and the data is limited to wind farm in excess of 45MW. This shows a performance ratio of around 25%, much lower than the oft repeated figures from the industry of 30%+ which is the benchmark when the number of homes supplied is calculated. It is reasonably safe to say that most wind farms in excess of 45MW are built in optimum wind sites whereas smaller wind turbines are usually much less efficient. After saying that I checked some north of Scotland 45MW ones and efficiency was nearer 21%. This would suggest that the 25% figure is potentially much higher than the real total output of UK wind. However after saying that it is not difficult to identify and quantify those sites near to and effecting you and any criticism is less on the excellent information provided as the obviously falsehoods of such as Scottish Renewables and Renewables UK that this site exposes. The fact remains that the 25% figure obscures the reality that when the wind does not blow the output is 0% of capacity and no amount of spin will change that. Rather akin to the meaningless 100% Renewables target of the SNP Party. 100% of nothing is still nothing. That the Ministers have tried to hoodwink the electorate with sleight of hand more usual in a music hall and that is what their intention was, when challenged they hide behind the veil of macro economics which means little to the man on the Edinburgh Tram(?) who just wants electicity that he can afford.

Slightly mad. Always believes a cup is half full so continues to tilt at Wind Turbines and the politicians that seem to believe it is their god given right to ruin Scotland for a pot of fool's gold.
