I happen to come from a different spiritual tradition than the Archdruid of the Ancient Order of Druids in America, but I really like his blog.
http://thearchdruidreport.blogspot.com He talks a lot about the energy economy, including biofuels and agriculture.
He's great about being reasonable and logical, but like a lot of other commentators, he notes that people tend to use reason only in a few special circumstances. His blog constantly mentions the power of myth to frame discussions. Logic can move people around within such a frame, or gently suggest that their frame is incomplete, but it takes another sort of work to get outside of a frame.
I think I agree with him that the myth of progress, taken at face value by too many, is a big part of the problem here. Complete faith in progress would suggest that we can use biofuels more rapidly in the next century than we used fossil fuels in the previous century, even though economics, ecology, logistics etc. don't support such an idea.
I believe in progress, but in the way that a lapsed Catholic believes. Nurturing more appropriate myths seems to be the way forward. And perhaps some techniques for that can ethically be borrowed from advertising/marketing toolkits, though certainly many of their means are unjustifiable by the best of ends.
