Winds of change

IT APPEARS that Alan Shaw (Letters, 24 January) has, in his rush to contradict me, failed to read my letter of 17 January properly. Rather than quoting "two months in summer and winter over the 58 years 1949-2007", I used the examples of July and August (mean figure 8 knots), February and December (mean figure 10 knots) and January and March (mean figure 11 knots). Six months from each of those 58 years. In fact, the maximum recorded gust was 22 knots at

I am fully aware that wind is a very variable natural resource. It is surely obvious that what is needed is a method of storing this clean energy so that it can be released when demand is greatest.

Furthermore, unlike Alan Shaw, I wasn't talking about "the UK". I realise that the Scottish Government's target is to generate 50 per cent of Scotland's electricity from renewable sources by 2020.
