I’ve spent years working inside the energy sector. Watching projects get announced, delayed, restructured, and sometimes quietly cancelled.
And in all that time, one thing has bothered me more than anything else: the gap between what politicians say about the UK’s energy transition and what the data actually shows. So let me share what I’ve seen, because I think people deserve a more honest conversation about this.
The Electricity Number Is Technically True. But It’s Only Part of the Story.
You’ve probably heard that renewables now supply around 52% of the UK’s electricity. That’s real. That’s progress. I’m not dismissing it.
But electricity is only one slice of the UK’s total energy use. The moment you look at heating, transport, and industrial processes, all of which still run predominantly on oil and gas, that impressive figure starts to look much smaller. The progress in clean electricity is real, but it does not tell the whole story.
Based on International Energy Agency (IEA) business-as-usual projections, oil and gas remain the backbone of the UK’s energy system for decades, with their share only falling from roughly 68% to around 40% by 2050. By contrast, the Climate Change Committee’s net-zero pathway requires that figure to fall to 20% or less. The difference between where we are heading and where we need to be is substantial.
That’s not a political statement. That’s what the numbers say.
