Paul Mobbs is the author of what I think is the best introduction to Peak Oil, especially for UK readers (see here).
This is an optimistic interview with him. "The whole point about modern society in Britain is that the only way we know to have fun these days is to expend energy. We need to relearn all those skills our grandparents had for having fun with very little. That’s what its really going to be about. If you look at human history, we can bear anything, so long as we have a bit of fun at the same time. The fun bit is what we really have to work on."
NB I'm booked to talk to our council about Peak Oil in the next few weeks. The Totnes model seems to be the way that Mersea needs to go forward.
