The peak oil activists that I've met are into relocalization by encouraging people to develope 19th century skills, gardening, sewing, pottery making, etc. (And that's more technology that a few I've met who think that Eden was when humans were hunter gatherers).
I'm all for relocalization and distributing the means of production as widely as possible, but I'd rather be using desktop fabbers and decentralized community networks (like seattle wireless).
I even agree with the idea that technology wont save us from the various global catastrophies that we're facing. We really do need to include social change, we need to replace the throw away society with one where everything is reused (somehow).
In the US we could really stand to be less worshipful of the car and start switching to some more energy efficient transportation options like bicycles, trains, skateboards, rollerblades, walking, neighborhood electric vehicles and hyper efficient small cars.
Some time ago I heard an idea that there was actually a large swath of american society that was against change. The cultural conservatives were trying to reverse social change, and large chunks of the green types were trying to reverse technological change. But in both cases they're trying to return to some imagined golden age.
If there's anything all of my reading of about various future scenarios has left me with, is that the fealing that future is going to be radically different from today.
