Decarbonisation is Labour’s next green policy disaster

Keir Starmer isn’t even in Downing Street yet already his government-in-waiting is in danger of being defined by its £28 billion green spending pledge, just as Tony Blair’s administration was defined by ‘45 minutes’ – the claimed deployment time of Saddam Hussein’s fabled weapons of mass destruction. First, Starmer promised to spend that sum on green initiatives in every year of the next parliament. Then it was revised down to spending £28 billion in the last year of the next parliament. Last week he dropped the pledge and said instead that £4.7 billion a year would be spent on green investment.

But in the melee a more rash policy has been overlooked: Labour’s pledge to decarbonise the electricity grid by 2030 – which brings the present government’s target forward by five years. This is one of the five great ‘missions’ laid out in the party’s pre-manifesto pitch, along with the creation of a state-owned company, Great British Energy, to achieve it. Not only will it save carbon emissions, Labour claims (without any evidence or published workings) but it will also save us an enormous amount of money, taking ‘up to £1,400 off the annual household bill and £53 billion off energy bills for businesses’ within six years. This is quite a boast, considering the average household pays £1,928 a year in energy bills.

A large part of Labour’s decarbonisation plans are laid out in a document called ‘Make Britain a Clean Energy Superpower’. Labour says it wants to quadruple offshore wind and double onshore wind by 2030, as well as to triple solar capacity. But this is likely to be impossible, not least because the National Grid won’t be able to get hold of enough subsea cables to plug in the required number of extra offshore wind turbines.
