The cambridge physicist David MacKay has written a book analyzing
various energy strategies at http://www.withouthotair.com/ he also has
a blog http://withouthotair.blogspot.com/
Very good from what I've read so far on the costs of various energy

BTW in regard to biofue etc. it is worth pointing out that there is in
fact quite a lot of land that is now out of production but which used
to be used until fairly recently. E.g. in the former soviet union -
Faber's Fourth Law:
Necessity is the mother of strange bedfellows.
