Before the wind
Mr Beisly (The Press, September 24) suggests that the UK should rely on gas for energy generation rather than wind power as the later is unreliable because wind is intermittent.
In fact wind farms in the UK generate energy between 70 per cent and 85 per cent of the time and what he fails to mention is that all forms of energy generation are intermittent.
No power station, whether fuelled by coal, oil, gas, or nuclear fission operates all the time, but is out of action at regular intervals either to fix faults, address safety concerns, or for routine maintenance.
In this respect wind power has the advantage of being a simple technology and less likely to need either maintenance or repair.
There is certainly no possibility of a wind farm being out of action for six months as the biggest reactor at Sizewell B was in 2010 because of technical problems, or all four nuclear power stations along the Loire, in France, in 2003 because the river contained insufficient water for cooling.
But then it is also worth noting that wind is both locally sourced and free, unlike gas, which increasingly has to be imported from Norway and Qatar, thereby helping to keep our fuel bills high and the country’s balance of payments in the red.
