 King Canute could not turn back the tides; he acknowledged his powers were limited. Similarly, UK politicians must recognise that our geographic location, climate and weather patterns are major determinants of future energy policy and that they can try but will fail to alter them. The energy trilemma, a phrase that rightly suggests the difficulty in balancing the competing demands of affordability, reliability and sustainability, should be set against the UK’s particular energy needs.
