Around three years ago, I put together a chart showing the breakdown of gas prices from 2000 to 2011, mostly because I was intrigued that the gas tax hadn’t been raised since 1993. Pulling data from the U.S. Energy Information Administration, I put together a static chart that was pretty powerful, showing that while taxes have remained steady—as, for the most part, have marketing and distribution—the cost of refining and for crude oil have swung dramatically. Some of the biggest drops were due to September 11th, Hurricane Katrina, and the market crash.

Three years is a long time, so I wanted to revisit the chart and make it interactive; you can now scroll over the data in the chart above to look at individual months. So you can zoom in a little closer, here is a look at the prices during the Bush administration:

And for Obama’s:

One final note: The U.S. Energy Information Industry compiles their numbers in kind of an odd way—they show what percentage each component contributes to the overall price of a gallon. (ie: In January 2000, a gallon of gas cost $1.289 and 7.8% was from refining.) I’ve converted those percentages to dollar amounts, which is why the taxes fluctuate slightly, from $0.40 to $0.47.
