A few months back, I recommended an excellent article published in Harper's titled "The Oil We Eat" by Richard Manning. In case you have a mindless job but plenty of bandwidth and like to listen to people talking instead of music, you can listen to an mp3 of Lynn Gerry reading the article (hostess of "Unwelcome Guests"). The second hour of the show is an interview with David Holmgren talking about Peak Oil and Permaculture.
