Summary
Jason Ormiston claims a 100MW windfarm will supply the needs of 460,000 homes (Letters, July 24). However, the British Wind Energy Association website shows 767MW of capacity is required to supply 440,000 households. I will leave it to the wind-lobby to get their sums to add up, but I must take issue with Mr Ormiston's statement that wind-turbines "reduce" CO2 emissions. The appropriate term to use here is "postpone".
Let me illustrate with an analogy. Suppose I go away on a business trip but discover I have left my mobile-phone charger at home. This presents me with a problem, since I am going to be away for three days, but I know the battery will only last for two. However, I work out that I can save some of the battery power by switching the phone off during the eight hours each day when I am asleep. By this means, I save a total of 16 hours battery life during the first two days, which is enough to keep the phone working for the waking hours of the third day. The total battery power used over the three days is exactly the same; all that I have achieved is to prolong the life of the battery. At the end of the three days the battery is flat whatever I do.See the full content of this document
