Why UK Electricity Is So Expensive

In this episode of The Winston Marshall Show, I sit down with energy analyst and commentator Kathryn Porter for a wide-ranging conversation on Britain’s energy crisis, the true cost of Net Zero, and the growing risk of blackouts.

We examine the rapid transformation of Britain’s energy system, the push towards renewables, and the unintended consequences of dismantling reliable baseload power. Porter explains why the UK grid has become increasingly fragile, why electricity prices remain among the highest in the developed world, and how energy policy is now colliding with economic reality.

The conversation explores the technical limits of wind and solar, the challenges of storage and grid stability, and the risks created by over-reliance on intermittent power sources. We also discuss nuclear energy, gas, and the geopolitical pressures shaping energy markets, from supply shocks to global competition for resources.

Finally, we debate the political incentives driving Net Zero policy, the widening gap between rhetoric and engineering reality, and whether Britain is sleepwalking into an energy crisis that could carry serious economic and social consequences.

A hard-headed conversation about energy, economics, and whether Britain’s climate ambitions are colliding with the physical limits of the grid.
