It is curious how quickly geopolitics can make yesterday’s certainty look a bit flimsy.
Oil jumps 30 per cent in a matter of weeks because two men decide to rearrange the Middle East with explosives, and suddenly the idea of importing vast quantities of fuel from volatile regions looks less like robust economic planning and more like wishful thinking with a spreadsheet attached.
For years we have been told that Net Zero is an expensive affectation, a hobby for metropolitan liberals who enjoy windmills and lentils. The argument runs that we are crippling ourselves while the rest of the world burns whatever it fancies. Better, apparently, to double down on fossil fuels and abandon the green fantasy.
Yet here we are, watching Brent surge because the Strait of Hormuz might become a shooting gallery. Every spike is effectively a tax on the British economy. It feeds straight into petrol prices, inflation, household budgets and industrial costs. We do not get a discount for scepticism. We pay the world price like everyone else.
The awkward truth is that renewables are not primarily a moral crusade. They are an insurance policy. Once you have built a wind farm, nobody in Tehran can make it more expensive out of spite. Once you have electrified transport, at least in part, you are not checking the oil futures market before filling the car.
Of course, it is not simple. Wind needs storage, grids need upgrading, EVs need infrastructure. None of this is cheap, and none of it happens by chanting slogans. But compare that complexity with the alternative, which is continued exposure to global commodity markets that can lurch on a Sunday evening because someone pressed a red button.
One wonders whether those still promising to “ditch Net Zero” have factored this in. If your central claim is that fossil fuels equal security and prosperity, a 30 per cent oil spike caused by geopolitical tension is not terribly helpful. It rather suggests that dependence on traded hydrocarbons equals volatility and vulnerability.
Perhaps the new line will be that we should drill more at home. Fine, where commercially viable. But North Sea oil is sold at global prices too. It does not come with a patriotic discount at the pump in Yate or Newton Abbot. The market does not care about flags.
As for me, I shall continue quietly generating my own electricity with solar PV, warming water with solar thermal, and letting the ASHP hum away in the background. It does not make me virtuous and it certainly did not come free, but it does mean that when oil spikes because somebody somewhere fancies a bit of brinkmanship, my exposure is at least slightly less than it might have been.
