Letter: Wind statistics raise questions

Here we go again. The unsuitability of a wind farm on the site at Woolfox does not seem to have deterred REF who presmably would receive a large subsidy.

We would all love to have clean energy but it needs to be economic. Data on wind speeds at Wittering, which is only a few miles away, for the years 2000 to 2010 show that; for 38 per cent of the time, the wind was between 0 and 4 metres/sec, for 49 per cent of the time, it was between 4 and 8 metres/sec, for 11 per cent of the time, it was between 8 and 12 metres/sec. Most wind generators need 12 metres/sec to generate their maximum power capacity.

So, for most of the time at the site, they would generate far less than the stated power and would be providing zero for at least one third of the time. To say that it would supply 90 per cent of the power for Rutland is pie in the sky. I hope Rutland County Council does not sacrifice our green and pleasant land by believing this optimistic projection.

The solar panel array is far less intrusive but it is also subject to the weather variations. How many hours of sunshine do we really get on an average winter day? For the whole of Germany during 2012, the wind farms produced only 17 per cent of their potential output. Even in Scotland, the figure was only 24 per cent. So what chance has the Woolfox site of generating significant energy? It has to be said that the only controllable and consistent carbon free energy is via nuclear power, unless we can perfect carbon capture from our coal and gas fuelled generating stations.
