The 'Wind turbine' article (NCE 8 February) highlights a worrying aspect of the rush to renewable energy.
In some ways I hope that there is something fundamentally wrong with the installation if it only produced a total of 27 pence worth in its first three weeks.
B&Q is to be congratulated on entering the field with their domestic wind turbine as mass production will hopefully bring prices down, but examination of the data provided raises concerns.
The unit is rated at 1kW, but this is at a wind speed of 12.5m/s, i. e. 28mph. It only cuts in at 3.5m/s to 5m/s (8 to 11mph), and shuts down at 14m/s (31mph).
To my mind that data does not suggest that the units will be very productive.
Are we really saying that there is inadequate information on wind strengths and duration around the UK to assess the effectiveness of such turbines?
It makes me worry about the larger versions springing up all over the place.
