The 20-20-20 targets oblige the countries of the European Union to reduce by 2020 their carbon emissions by 20% from 1990 levels, to increase their share of renewables in energy to 20% and to increase their energy efficiency by 20% also from 1990 levels. Yet, one needs to be careful not to privilege this dimension to the exclusion of all others. A cautionary example is provided by the otherwise interesting and well-informed presentation by Professor John Gittus, Lloyd’s of London, with the title Keep the Lights Burning. Insisting heavily on future turmoil in the Middle East and future interruptions of Russian gas, he raises the spectre of a return to “three-day week” in absence of drastic action and predicts a blackout in the United Kingdom by 2025 with a 75% loss of electrical power lasting more than one day with “2 to 5% probability” (Gittus, 2004, p. 7).
