Both left and right are deluding themselves about the scale of the energy crisis Britain faces | Ewan Gibbs

Decades of complacency cannot be magicked away by drilling in the North Sea – or even by hoping that renewables will quickly power everything

First it was Russia’s full-scale invasion of Ukraine, now it is the blockade of the world’s petroleum artery in the Gulf. For the second time in four years, Britain is facing an energy crisis that has been made much worse because of the absence of preparation by its political leaders.

The fact is that our energy politics were conceived for a world where convulsive, global events were a thing of the past. The notion that it would be difficult to access supplies of oil or liquefied natural gas from the international markets did not figure in the understanding of the politicians and officials who shaped our perilous current moment. But even today, the advocates of energy sovereignty on the left and right appear to lack knowledge, understanding or power over this very foundational matter.
