You are essentially pointing at the same fault line from a different angle.
The arithmetic is already there it's on cost, system stability, capacity factors, grid reinforcement, storage requirements, and defence resilience. What hasn’t caught up is institutional acceptance of what that arithmetic implies. Narratives can persist well past their sell-by date when they are embedded in party identity, donor ecosystems, and bureaucratic incentives.
On your specific point about security: you are correct, and this is not controversial in serious defence or systems-engineering circles. Intermittent generation is not security infrastructure. It can be part of a diversified system, but it cannot be the backbone of a sovereign state’s energy, industrial, or defence posture. Militaries plan for worst-case availability, not average conditions or “annualised” outputs. A power system that depends on weather-correlated assets is, by definition, vulnerable.
As for whether “grown-ups” are explaining this: yes, almost certainly. The UK has no shortage of senior figures from defence, grid operations, and heavy industry who understand these constraints perfectly well.
The more uncomfortable question is whether Keir Starmer either: believes the transition can be patched with future technologies and political goodwill, assumes the hard trade-offs can be deferred beyond the current electoral cycle, or accepts the arithmetic privately but judges the narrative politically untouchable for now. History suggests it’s usually the third.
There is also a category error at play. “Security” in political discourse has been rhetorically downgraded to emissions accounting and supply diversification, whereas state security actually means availability under stress: prolonged cold, low wind, cyberattack, war, supply chain disruption. On those metrics, intermittency fails before the debate even starts.
So yes here the emperor has no clothes. The problem is that acknowledging that fact forces explicit choices: higher visible costs, domestic extraction, nuclear timelines, and honest rationing of ambition. Politics tends to avoid those moments until physics makes avoidance impossible.
