Pessimism of the intelligence, optimism of the will
The Archdruid continues his wonderful series:
That airy optimism about technologies that haven’t yet gotten off the drawing board is not a useful response to an imminent crisis in the real world. This is a point worth keeping in mind, because airy optimism about technologies that haven’t yet gotten off the drawing board is flying thick and fast just now, especially but not only in the peak oil scene. Mention that industrial society is in deep trouble as a result of its total dependence on rapidly depleting fossil fuels, in particular, and you can count on a flurry of claims that Bussard reactors, or algal biodiesel, or fourth generation fission plants, or whatever the currently popular deus ex machina happens to be, will inevitably show up in time and save the day.
One of the things that has to be grasped to make sense of our predicament is that this isn’t going to happen. Some of the reasons that it’s not going to happen differ from case to case, though all of the examples I’ve just given happen to share the common difficulty of crippling problems with net energy. Any attempt at a large-scale solution at this point in the curve of decline faces another predictable problem, though, which was discussed back in 1973 in The Limits to Growth: once industrial civilization runs up against hard planetary limits, as it now has, the surplus of resources that might have permitted a large-scale solution are already fully committed to meeting existing urgent needs, and can’t be diverted to new projects on any scale without imposing crippling dislocations on an economy and a society that are already under severe strain.
The green wizardry being developed in these posts thus seeks to craft responses to the crisis of our time that don’t ignore the predictable impacts of that crisis. For this reason, we aren’t going to be exploring the sort of imaginative vaporware that fills so many discussions about our energy future these days.
