Imagine this. It's January 2015, you're David Cameron, you're Prime Minister and you're planning your re-election campaign in a few months.
And then the lights start going out. Power cuts sweep the nation. You're forced to introduce power rationing. How on earth can you win an election in those circumstances.
That's the scenario which The Economist paints this week. If it is correct in its diagnosis, unless something radical is done, Britain is heading towards South African Style power cuts by 2015 because demand for electricity will exceed available supply.
Quoting directly from the Leader - "In terms of energy policy, this is almost criminal - as bad as any other planning failure in New Labour's 12 year reign."
The Conservatives are likely to be the Government when Britain feels the effect of New Labour's failure to plan but who is likely to get the blame? - the government of the day of course.
Energy is not exactly at the top of the league of political sexiness. But without a proper energy supply strategy the whole economic house of cards comes crashing down.
I wouldn't presume to suggest what the solution is as I have very little knowledge, but what we have got to avoid if at all possible is any huge reliance on energy supplies from Russia. We have already seen where that leads. Greg Clark and his shadow energy team have a job few of us would envy.
