Claudia Dávila’s Luz: Girl of the Knowing is a cheerful webcomic about an ominus situation: the coming oil shortage. Spurred by the simple fact that world oil production has peaked and will decline from here on in, Dávila decided to use the medium of comics to teach some simple lessons about the coming crisis and ways to cope with it. Luz, the title character, copes with blackouts, thinks about what she may have to do without someday, and learns about gardening by watching her neighbor, Mrs. de Souza.
Despite her gloomy topic, Dávila emphasizes the positive and the practical. In one episode, Luz watches Mrs. de Souza harvest and preserve her tomatoes, and Dávila includes a link to a page explaining how to dry your own food. Blackouts inspire an impromptu barbecue. And when Luz visits the farmer’s market in January, she learns that she can have local food even in the dead of winter. While Luz can get a little earnest at times, as when she gives a presentation on peak oil to her class, her friend Robert, an internet addict with a thing for stuffed bunnies, helps keep it real.
