Interesting approach to bio-energy

This was written quite a while ago, but as I was talking to some other Industrial Ecology students the other day about this I realised it's actually a good article if you're interested in the subject. It's very subjective by nature (that's what it's a blog for), but the systems approach is presented clearly.
The whole article is pretty thorough and not exceptionally long.

On a side-note I think it's sad that the author (who goes by the name of Engineer-Poet) decided to stop blogging...

So, without further ado: Sustainability, energy independence and agricultural policy
