The
Post Carbon Reader, edited by Richard Heinberg and Daniel Lerch, is a collection of essays that attempt to synthesise the various challenges we face and how we might respond to them. Much of it is available online. Read Heinberg's piece
Beyond The Limits To Growth (the first article linked from the page linked above) and one other that takes your fancy (Matt currently has the hard copy of the book if the article you'd like to read isn't one of the one that is available online).
