I was a principal scientist for the oil company Shell, for which I worked for 33 years. I have a degree in aeronautical engineering and a PhD in fluid mechanics.

I recently read a letter from the business and energy secretary, Kwasi Kwarteng, in which he tries to justify government plans to encourage investment in new North Sea oil and gas. He says it would “protect Britain’s energy security” and smooth the “transition to cheap, clean, home-grown energy”, as well as cutting energy bills.

But expanding North Sea oil will do none of those things, for several reasons.

We don’t own the oil and gas, which we give away to energy companies together with substantial subsidies. They sell the oil and gas to the highest bidder on international markets, keep all the revenue, and are currently making eye-watering profits on which they pay almost no tax. Almost 80 per cent of UK production of crude oil is exported and plays no part in our domestic energy security.

We don’t own the companies that exploit this oil and gas. According to one study, more than a third of the licence blocks in the North Sea now have a private or state-backed controlling interest, with fossil fuel firms from China, Russia and the Middle East playing an increasingly dominant role. As well as being unaccountable to UK shareholders, these businesses have no strategic interest in UK energy security or in keeping bills low for UK households. read more
