So watching the Pickens commercial below gave me a thought. He was discussing dependence on foreign oil and showed some percentages of how much we import. So I went to the data. In terms of foreign oil I went to the Energy Information Administration and pulled an excel chart for historic crude oil imports and production. Since its monthly I averaged 1970,1990, and 2005. T Boone uses current 2008 to say 70% but the most recent transportation data is from 2005. So foreign crude imports went from 12% to 44% to 66% of the total U.S. supply.
Then I went to the BTS and found the Vehicle Miles Traveled (VMT) charts and put the totals together. A word of caution from the last chart I put up. Correlation doesn't necessarily mean causation, but I thought this was interesting and more relative. If anything I hope it starts some discussion on how this oil dependence is related to our auto dependence.
Perhaps its also related to this: Spending on highways over transit from PIRG.
I'm going to go out on a limb here and say that our transportation policy has led us to this predicament. I believe we all knew this, but its always good to have charts right? Thoughts?
