The Met Office said there has been an unusually long period of high pressure across the UK for the last couple of weeks, causing the cold snap and very little wind.What a surprise--windfarms at the mercy of the wind.
Since Boxing Day much of the country has suffered sub-zero conditions with frozen rivers and lakes and even the sea in the south of England, at Sandbanks in Dorset. In the last few days temperatures in southern England plunged as low as 17.6F (-8C). However the weather is expected to warm up over the weekend, with wind speeds also picking up.
But sources in the energy industry say that the lack of wind has caused the country's wind farms to grind to a halt when more electricity than ever is needed for heating, forcing the grid to rely on back up from fossil fuels or other renewable energy sources.
In the long term, experts fear that the intermittent nature of wind will force the UK to rely on insecure energy supplies, for example gas from Russia, and are calling for a greater energy mix including controversial nuclear and coal-fired power stations.
