Aka the Amish, or even Mennonites. I spend a good deal of time in close proximity to these communities and they seem to mix old world / close-to-earth living (horse and buggy etc.) with new world-tech (solar/wind electricity generation). Each community has their own "rules" but it seems to be close to what you're describing (maybe minus all the religious stuff) I do see them at Wal-Mart ... so there's that.
