There are many things that I don't understand. Like why a day return rail ticket between Edinburgh and Glasgow costs £22 when we are trying to get people to stop using their cars. Or why a cup of coffee costs £2.50 when its ingredients cost 0.5p. But nothing puzzles me more than energy prices. They have doubled in five years even though Scotland is sitting on a mountain of power. Yesterday, we were warned by Alistair Buchanan, the chief executive of Ofgem, the energy regulators, that energy prices are going to soar again because of something called a "gas crunch". We haven't seen anything yet. The lights will go out.
Now, every six months or so there is a scare about lights going out (LGO). The most recent - inevitably - was a warning that independence for Scotland would lead to LGO because England wouldn't continue to subsidise Scottish power generation. This seems utterly baffling since Scotland has a vast surplus in electricity generation at the moment and is sending the surplus south.
Ah, but that's only because of those nasty fossil fuel stations like Cockenzie that are being closed down. And nuclear power stations like Torness that are coming to the end of their unnatural lives and will not be replaced because, according to Labour, the SNP is irrationally biassed against nuclear power. Labour have for years been predicting LGO without more nuclear power stations, which the Scottish government has ruled out on the grounds that they would be hugely expensive, dangerous and surplus to requirements.
At present, Scotland has total energy generating capacity from all fuel sources of just over 12 GigaWatts - or so I am told. By 2020, we will have the capacity to produce 100% of electricity demand from renewable sources like wind. Scotland supposedly has wind, wave and tidal energy potential of 60GW - six times current capacity. We have 25% of Europe's wind and tidal and 10% of wave energy potential - a colossal comparative advantage in green energy.
And these aren't fantasy figures from some environmental pressure group. 20 GW are already in the pipeline, according to the Scottish government, which is nearly twice what we have now. We already provide nearly 40% of the UK's renewable energy output - which is why the UK government has been helping subsidise the development of the Scottish renewable energy, so that Scottish wind can help England meet its climate change targets.
So, lights going out? I don't think so. Unless this is all garbage. But assuming ministers are not lying, we seem to have rather a lot of energy. Indeed, we still have a trillion pounds worth of oil in the North Sea, prodigious amounts of Scottish coal and a lot of the latest fad - shale gas, which is supposed to be worth £5nb a year in Scotland alone if fracking (that's a method of extraction not a term of abuse) turns out to be safe. Germany would love to have our renewable energy sources - they are turning green and phasing out nuclear powers stations at the same time. But they are of course German, and their lights do not go out.
