The Guardian hits the right note on energy policy choices in the aftermath of the still unfolding Japanese nuclear crisis:
For all the emotive force of events in Japan, though, this is one issue where there is a pressing need to listen to what our heads say about the needs of the future, as opposed to subjecting ourselves to jittery whims of the heart. One of the few solid lessons to emerge from the aged Fukushima plant is that the tendency in Britain and elsewhere to postpone politically painful choices about building new nuclear stations by extending the life-spans of existing ones is dangerous. Beyond that, with or without Fukushima, the undisputed nastiness of nuclear – the costs, the risks and the waste – still need to be carefully weighed in the balance against the different poisons pumped out by coal, which remains the chief economic alternative.
Most of the easy third ways are illusions. Energy efficiency has been improving for over 200 years, but it has worked to increase not curb demand. Off-shore wind remains so costly that market forces would simply push pollution overseas if it were taken up in a big way. A massive expansion of shale gas may yet pave the way to a plausible non-nuclear future, and it certainly warrants close examination. The fundamentals of the difficult decisions ahead, however, have not moved with the Earth.
