Yes. John, from the, admittedly, limited knowledge I have and from what I've read by an increasing number of scientists, there appears to be big question marks over the efficiency of windfarms, and indeed, renewables in general. Here's Sir David King, a quote from the FT:
"Sir David said that big increases in the amount of energy from wind were problematic because of its inherent intermittency - the wind is unpredictable and cannot be guaranteed to blow at the times electricity is needed.
"He said: 'If you oversupply renewable energy you run the risk that at high demand periods there may be no wind. If you're overdependent on wind you create a problem with security of supply.'
"Sir David believes the best way to generate lowcarbon energy is to improve energy efficiency and to increase the proportion of electricity generated from nuclear power.
'With nuclear I think it's wise to go to 40 per cent of maximum demand," he said. That would require up to 20 new or replacement nuclear power stations by 2025.'
I've been reading an increasing number of statements like that so there is already doubt about the value of large scale windfarm developments, in the numbers the Government is suggesting, within the scientific community. I'd be the first to admit that the politicians are more likely to listen to scientists than the likes of me but that growing doubt within the scientific community gives me the encouragement to fight these developments from a different angle, the wild land preservation angle, and that's something I do know a little about. Incidentally, there are a number of ministers within the Scottish Government who are not convinced about over reliance on renewables. From what I can gather that's the reason the decision on the Beauly-Denny powerline has been delayed yet again.
I'm also pragmatic enough to realise that large scale, ugly, environmentally-damaging windfarms will be built on wild land areas, but that doesn't mean I should stop campaigning against large scale windfarms in general.
Incidentally, on a slightly different note, I'm saddened that Davie Black, the Ramblers 'expert' on windfarm development, has been one of the victims of the Ramblers cuts. I asked the chair of the board and the CEO Tom Franklin what the Ramblers policy on windfarms was now and they couldn't, or wouldn't tell me. I guess they don't want to rock the New Labour boat...
Finally, now that people are beginning to realise that renewables are likely to send their energy bills sky-high then there will be growing lobby campaigning against them. In the near future the question is likely not to be "do we have enough energy capability?" but, "can we afford to pay for the energy we use...?"
