• The Energy Coefficient of the United Kingdom

    • Date: 04/06/16
    • Dr John Constable: GWPF Energy Editor

    Total primary energy consumption in the United Kingdom has fallen more or less steadily for a decade. This makes climate change targets seem more attainable, but does it bring problems of its own, or is it to be welcomed as a further stage of economic maturation? In 1979 William S. Humphrey and Joe Stanislaw, then at […]

  • The Capital Cost of Solar Photovoltaic

    • Date: 29/05/16
    • Dr John Constable: GWPF Energy Editor

    Data published by the UK’s Department of Energy and Climate Change this week suggests that the capital cost of small-scale (≤ 4kW) solar photovoltaic has begun to rise in the first part of 2016, reversing the downward trend of previous years. It is now questionable whether the earlier reductions were due to fundamental technological improvement, […]

  • UK Domestic Lighting Policy

    • Date: 22/05/16
    • Dr John Constable: GWPF Energy Editor

    In 2007 the UK government began to force incandescent bulbs from the lighting market, and coerced domestic consumers to purchase instead compact fluorescent lights (CFLs). Within four years government had succeeded in filling nearly all the UK’s 600 million domestic lamps with such bulbs at a cost of several billion pounds. However, with the recent […]

  • Divestment and the Future Uses of Oil, Gas and Coal

    • Date: 15/05/16
    • Dr John Constable: GWPF Energy Editor

    Coal is now only a trace element in the UK’s electricity supply; Saudi Arabia is selling shares in Aramco. Is it all over for fossil fuels? Or have we simply misunderstood where the future utility of these remarkable substances really lies? Over the last year there has been an increasing tendency for climate change activists […]

  • Renewable Transport Fuel May Be Bad, But It Is Cheap(er)

    • Date: 08/05/16
    • Dr John Constable: GWPF Energy Editor

    The EU has revealed that because of environmental criticisms there will be no renewable transport fuel component in any Renewables Directive post 2020. But the biomass liquid fuel sources thus driven from the market are relatively cheap, and the renewables for electricity that must take up the slack are comparatively expensive. This new direction increases […]

  • Energy and the Theory of Growth

    • Date: 01/05/16
    • Dr John Constable: GWPF Energy Editor

    Energy matters to economic growth and general prosperity, but to what degree? Over the last thirty years a new view of the English ‘Industrial Revolution’ is beginning to take shape that suggests it matters much more than is allowed for in mainstream economics, a development that gives further reason for concern about global attempts to reduce […]

  • The Collapse of SunEdison

    • Date: 24/04/16
    • Dr John Constable: GWPF Energy Editor

    Does the failure of SunEdison, which has just filed for bankruptcy in the United States with debts of $16.1bn, tells us anything about the renewable energy in which it invested? Perhaps not, perhaps we should exonerate the technologies and put the blame on financial engineering, which does appear to be one of the great misnomers […]

  • Energy Efficiency (and Conservation) and Climate Policy Cost

    • Date: 17/04/16
    • Dr John Constable: GWPF Energy Editor

    The long expected but now manifest failure of the UK government’s Green Deal and Energy Company Obligation (ECO) energy efficiency schemes, which were predicted to offset the impact of climate policies, combines with low fossil fuel costs to make it essential that the UK government resumes publication of its analysis of the policy impacts on […]
