DoE statistics, from 1949 - 2003, in three graphs. All oil usage. All energy usage. Residential oil usage. One note: The "energy" line in the "all energy" graph is not additive with the others. It simply indicates the amount that is converted at power plants first. Oh, and here is a link to a couple informative and attractive images from NASA concerning Katrina and New Orleans. By the way, I made all these graphs from the raw data.
