The energy challenge: Can we keep the lights on?

As an energy crunch looms large and existing sources of energy such as ageing nuclear power stations go off stream there is still little investment in future energy resources. Some argue for more nuclear power, some for massive investment in renewables, some have even welcomed the recent recession as a curb on our consumption. Have we got enough energy? Is it imperative for energy policy to be dictated by concern about carbon emissions, or is there an argument for energy for its own sake, whatever the weather?
