RCP8.5 as Implausibility Sinks In

The fallout from the recent Intergovernmental Panel on Climate Change (IPCC) ruling that computer model high emissions pathway RCP8.5 is “implausible” is only just beginning. Most mainstream media fearmongering stories over the last 15 years need to be moved into the junk file, as do the increasingly shrill sandwich-board pronouncements of King Charles and Sir David Attenborough. But the rot goes much deeper than ill-informed public comment, although that alone has been enormously influential in promoting the Net Zero fantasy. Activist-ridden science bodies such as the UK Met Office have brazenly used RCP8.5 to flam up weather predictions which in turn has led to onerous requirements being placed on British industry and finance. Politicians have been convinced by patently ridiculous claims and Net Zero rules and regulations have cascaded through the economy and society.
All the politicised predictions need to be junked and all the resulting regulations reconsidered with a view to abolition. They are all based on assumptions that many at the time said were ridiculous and have now been officially marked as not wanted on voyage. Those inclined to be uncharitable might suggest it was all a hoax from start to finish.

Scotland's Looming Energy Crisis — Key Points
1. The "electricity superpower" myth Porter opens by challenging the popular notion that Scotland is an energy superpower. In reality, Scotland's grid is held together by just two power stations — Torness (nuclear) and Peterhead (gas) — and the National Energy System Operator (NESO) will not allow both to go offline simultaneously for maintenance.
2. How electricity grids actually work She gives a detailed explanation of why grid stability is a physics problem, not a political one. Conventional power stations maintain grid frequency (50 Hz) and voltage through natural electromagnetic "inertia" — they resist fluctuations automatically. Wind and solar, by contrast, use inverters that are "grid following": they need a stable grid to operate and cannot form or stabilise one themselves.
3. Why batteries and renewables cannot fully replace conventional generation Batteries and inverter-based technologies can provide some support services, but only through complex, expensive control systems — not naturally. Grid-forming inverters remain experimental, with none proven at operational scale anywhere in the world.
4. The Iberian blackout of April 2025 Porter argues clearly that this blackout — which cost 11 lives and caused an estimated 165 excess deaths — was caused by renewables. A cascade failure began with a faulty solar inverter, was worsened by wind and solar generators failing to meet grid code obligations during a frequency drop, and resulted in the entire grid collapsing within seconds. She uses this as a direct warning for Scotland.
5. Scotland's specific vulnerability Scotland already experiences voltage control issues and sub-synchronous frequency oscillations since the premature closure of Longannet coal station in 2016. The closure of Torness is scheduled by March 2030–2032, and Peterhead is ageing. With lead times for new gas turbines at 7–8 years, there is a realistic scenario where Scotland has no major conventional generator — a situation she describes as "a recipe for disaster."
6. Geography and transmission challenges Most electricity demand is in England, while most new renewable generation is in northern Scotland. Long transmission distances make voltage control harder, amplifying the need for strategically located synchronous generators.

ADDENDUM: The Energy Policy Dimension:
How the Net Zero and Decarbonisation Agendas Compound the Built Environment Crisis —
and Why Decentralised Bio-Methane CCHP and Urban Integrated Metabolism Represent the Correct Alternative February 2026 | Companion document to: The Deferred Reckoning
Introduction: A Compounding Error
The main report demonstrated that the UK faces an inherited infrastructure maintenance liability of £520bn to over £850bn — the result of generations of political short-termism, deferred maintenance, and misdirected spending. This addendum addresses a further and perhaps more consequential layer of the same problem: that the current energy policy framework, built around Net Zero and Decarbonisation orthodoxy, is now being imposed upon a building stock and infrastructure network for which it is profoundly unsuited.
The consequences are severe. An already creaking built environment is being asked to carry the additional burden of an energy transition designed around assumptions that do not reflect the reality of 30 million ageing buildings, Victorian utility networks, and a construction industry already overwhelmed by the maintenance backlog documented in the main report. The result is not transformation — it is the addition of one very expensive mistake upon another.
The central argument of this addendum: the UK's Net Zero strategy imposes maximum cost and disruption upon minimum-efficiency solutions, whilst ignoring a thermodynamically superior, economically self-funding, and practically deliverable alternative that has been available — and partially operational — for decades.
1. The Built Environment and Net Zero: A Fundamental Mismatch
The UK government's Net Zero strategy for buildings rests on several assumptions, each of which fails to withstand engineering scrutiny when applied to the actual housing and commercial stock described in the main report.

THE DEFERRED RECKONING
Britain's Built Environment: A Century of Under-Investment
An Assessment of Maintenance Failure, Remediation Costs and National Priorities February 2026
Executive Summary
The United Kingdom faces a remediation bill for its built environment that is, in the most candid assessment, colossal. Across housing, water infrastructure, transport networks, health and education estates, flood defences, and civic buildings, decades of deferred maintenance have compounded into an inherited liability now conservatively estimated at £520 billion to over £850 billion. The full figure, when accounting for energy retrofit obligations and climate adaptation, may exceed £1 trillion.
This is not a sudden crisis. It is the slow arrival of bills that were always going to come. Each generation of politicians — and to a degree, each generation of owners — chose the comfort of deferral over the discipline of maintenance. The compound interest on that choice is now due.
This report sets out the scale of that liability by sector, the realistic timescales for remediation, and asks a question that is uncomfortable but legitimate: have successive governments correctly prioritised the stewardship of domestic assets over the projection of spending abroad?
Note on figures: All cost estimates in this report are indicative. They draw on published government data, National Audit Office reports, industry body assessments, and informed extrapolation where official figures are absent or incomplete. They should be treated as orders of magnitude rather than precise projections.
