Jay, when I was a kid the media wrote of the year 2000 as some distant science fiction world where we would all wear silver suits, drive hovercraft and have strange haircuts. It didn't quite happen like that, except for my haircut. Same with our energy future, it won't all be like we read about now, but some things will.
We also grew up thinking that either the Russians or the Americans were going to blow us all up (I don't remember how we believed this and the silver suits thing...), which of course they didn't. We seem to avoid disaster despite ourselves, but not through precision planning.
Despite all our arrogance and confidence we don't seem very good at planning the future, and I mean that at a national and personal level. This might be seen as stupidity, but I've come to think that it isn't really possible to predict the future with any certainty - otherwise I'd be rich!! What government would have let the credit crunch happen if they'd predicted it? Who'd have gone to war in Afghanistan if they'd known it was going to be so difficult?
I'm starting to think that the best way of dealing with the future is to have some sort of loose plan, but:
a)..... Try to avoid specific actions (invade Afghanistan) where there is a broad range of unknown outcomes - you might not like some of them (war is chaos, so who was to know that they'd fight back!). Although we all laughed at Donald Rumsfeld's "unknown unknowns" comment, in retrospect it was probably the only sensible thing he ever said.
b) .... Try and create flexible situations where you'll benefit whatever the outcome. The Supergrid, or whatever it's called, seems to fit here quite well as although we can't predict which energy generation technologies will work best, we can create an infrastructure that supports them.
The technology of the atomic bomb seemed to have brought us to the end of the world forty years ago, and whilst I will concede that I don't have a personal robot to vacuum clean and make the tea, technology has brought us an awful long way from those days, and I don't see why technology can't take us to an even better future, but I don't know how. But I hope there are hovercraft.
