1974 - 2000 Energy-saving measures
Since buying my own home, I have applied a large number of energy-saving measures.
Initially, these were installed using my 'engineering judgement', rather than based on quantitative evidence.
- 1974 I installed additional insulation (glass fibre) in the loft, increasing the thickness from 50 to 150 mm (2 to 6 inches). I also fitted additional insulation (glass fibre) around the hot water cylinder.
- 1980 Thermostatic radiator valves (Drayton) were fitted to all radiators.
- 1980 The (50 mm) cavities of all the external walls were filled (with urea formaldehyde foam).
- 1988 Some new radiators were fitted (replacing those leaking), along with new thermostatic radiator valves (Drayton).
- 1992 All the original wooden single-glazed windows and external doors (which were rotted and had no seals - allowing draughts) were replaced with uPVC double-glazed units, with double seals.
- 1995 The original floor-standing Potterton Diplomat gas boiler was replaced with a new wall-hung gas condensing boiler (Potterton Envoy 40), and new outside compensator control (Danfoss BEM 5000). The original Primatic hot water cylinder was replaced with a new indirect cylinder (Range Supercal), with integral foam insulation. Also fitted were a new hot water header tank (replacing that corroded), a new heating system header tank (previously missing, causing corrosion), cellular insulation on the heating and hot water pipes (previously none), some new radiators (additional and larger), and all new thermostatic radiator valves (Danfoss).
- 1998 I started making measurements on my heating system, including use of an 'educational' data logger capable of measuring four temperatures.
- 2000 The Potterton boiler was replaced because of its appalling unreliability - about 16 failures in under five years. Potterton has since left the domestic boiler market (but sold the name to Baxi). A new super-condensing gas boiler (Eco-Hometec Micromat EC16/22), with integral outside compensator control, and a new, larger, indirect hot water cylinder (Range Ultracal), with a high-performance coil and double foam insulation, were fitted.
- Later in 2000, I bought and installed an 'industrial' data logger capable of measuring eight flowrates (as pulses from various flowmeters) and 14 (of a possible 16) temperatures (from thermocouples). Scanning 22 channels at one minute intervals, this measurement and logging setup provides data comparable with that from a world-class research laboratory. See Measuring the Heat Losses and Solar Gains of Buildings. It is still doing so after more than 15 years.

I watched videos on climate change by Professors Johan Rockstroem and Stefan Rahmsdorf of the Potsdam Climatological Institute in Germany.This prompted me to create the document ‘2024-10-12 A Note on Climate and Energy’.2024-09-17 Britain’s Atomic Bomb Scandal (Channel 4 programme)
Channel 4 made a multi-part series of programmes with this title.The sub-title was: The dramatic, shocking story of Britain’s race for the nuclear bomb, the devastating fallout for the servicemen at the tests, and the veterans’ long fight for justice'. I watched all the parts, and made notes.Then I typed up the notes and followed up mentions and links to produce this document.2021-09-29 Nuclear Power and the EU Taxonomy
Around September 2021, the European Commission considered the inclusion of nuclear power in the taxonomy for future investments in energy. This was based on a single report from the European Joint Research Centre, which still has close links with the nuclear industry and is widely perceived as playing a promoting role for nuclear energy within the European Union. The JRC Report ignored the report of the German Ethics Commission for a Safe Energy Supply of 2011, which had lead to Germany phasing out nuclear power by 2023. The European Commision also ignored 'Sustainability at risk, A critical analysis of the EU Joint Research Centre technical assessment of nuclear energy with respect to the "do no significant harm" criteria of the EU Taxonomy Regulation, of 2021-09 by Dr. Christoph Pistner, Dr. Matthias Englert and Dr. Ben Wealer, for the Heinrich Boell Foundation.2023-06-06 Nuclear Power Has No Future
The UK government proposes to build nuclear power plants totalling 24 GW.This implies Hinkley Point C, Sizewell C and about six more of similar size.The Labour party proposes to include nuclear power in it’s new ‘green’ energy policy.Yet nuclear power has no future, as shown in this document of 3 pages with 52 references. The first section shows that nuclear fuel may be effectively exhausted before 2050, when the climate targets should be met. The second section shows that the costs of nuclear power have risen over time, and are now uncompetitive. So nuclear power must be replaced by sustainable and affordable options such as energy savings and renewables like wind, solar and storage. The third section shows that nuclear power conflicts with energy savings and renewables, so impairing the business case and deterring investment.So the UK should phase out nuclear power and join the rest of the world in deploying energy savings and renewables.Although this document is published after the latest Government and Labour Party proposals,I have published many earlier documents on nuclear power, dating from 2006-0-19. (See below).Most notably, my report on the Fukushima disaster was published on 2012-04-11, with copies sent to several MPs and Ministers.2022-10-05 Nuclear Nonsense
The new UK government appears to support the previous government’s proposal of building new nuclear power plants. The Labour party proposes to include nuclear power in it’s new ‘green’ energy policy. However such nuclear proposals are nonsense, as shown in this 4-page due diligence assessment.2022-08-12 Stopping Sizewell C and all nuclear power in favour of a rational energy policy
Among the last acts of the Johnson government was the approval of a new nuclear plant - Sizewell C. The claim was that it would increase energy security and reduce carbon emissions. But the invasion of Ukraine has underlined that all nuclear sites are targets, and reduce national security. Also nuclear power would be far more costly than energy savings and renewable energy sources such as wind and solar, with storage, and could not be generating electricity before 2030. They need uranium for fuel, yet almost half comes from Russia and Kazachkstan, so that the money and carbon costs would increase twice as fast. Moreover, they require huge amounts of energy to manufacture and build, so reducing energy security until construction is complete, and this energy repaid. Yet Hinkley Point C and Sizewell C are coastal sites, at risk from flooding by sea level rise and storm surge by 2100. As decommissioning and site clearance would take at least 50 years, they would need to be shutdown before 2050. Many reasons for stopping Sizewell C and all nuclear power are given in this collection of five documents.2022-08-13 Nuclear Power And Weapons Are Killing Us
The Manhattan Project in the US covered every stage of the production of nuclear weapons. This included the mining and refining of uranium, enrichment to 80 to 90% U235 for uranium bombs, fuelling nuclear reactors with uranium to produce plutonium, and reprocessing the spent fuel to extract the plutonium for plutonium bombs. It was recognised from the beginning that these processes and plants would give rise to radioactive releases that would be harmful to the plant operators and the general public, yet they were never informed. This continues to the present day, when the nuclear weapon and power industry does everything in its power to deny and understate the many and extensive harms done to all living things. To this has been added the use of uranium in bunker-breaking bombs and tank-busting shells, that spread the dust so formed over their own forces, the enemy forces, and innocent bystanders, harming them all for generations to come. The human harms include many and extensive cancers, and also non-malignant diseases such as stillbirths, deformities and mental impairment and heart disease. With so much harm already done to humans that will take up to lifetimes to express, and so much nuclear debris laying in wait to harm even more humans, it is essential to identify every strategy and measure that can reduce the total harm.This document covers the first warnings of nuclear harms in the 1950s and - following studies beginning in the 1960s - five books of evidence by Dr Ernest Sternglass in 1981, Mr Harvey Wasserman et al in 1982, Dr John Gofman in 1990, Mr Paul Zimmerman in 2009, and Professor Chris Busby et al in 2010.2022-06-14 Energy Transition Technologies
This is prompted by the Energy Hierarchy of the Institution of Mechanical Engineers. From the most to the least sustainable, Tier 1 is Energy Demand Reduction, Tier 2 is Energy Efficiency, Tier 3 is Utilisation of Renewable, Sustainable Resources, Tier 4 is Utilisation of Other, Low-GHG-Emitting Resources, and Tier 5 is Utilisation of Conventional Resources as we do now.2022-06-18 Nuclear Insecurities
