I haven't commented much on Peak Oil because I decided that it would be impossible to see the peak until we are well down the far side. Couple that with most Americans' belief that cheap gas is a gl0d-given right, and you have a recipe for frustration. But I'm in a graphing mood, and energy happened to be the folder I clicked on today.
Update: I was remiss in not including the follow graph at the outset.
The graph contains some okay news: consumption per person has been roughly flat since the early 1980s. That means Americans are using less oil for each dollar of GDP created. Whether efficiency has gone up or a different primary fuel substituted for oil will be the subject of another post.
