very interesting website energy data

This DOE site always amazes me. Each time I check it out, I always find something interesting and useful. This is the latest section I found interesting and useful. http://tonto.eia.doe.gov/cfapps/STEO_Query/steotables.cfm?periodType=Monthly&startYear=1993&startQuarter=1&startMonth=1&endYear=2008&endQuarter=4&endMonth=12&tableNumber=20

You select the granularity you want and the data you want and download it to Excel. I plan on doing some simple gasoline analysis and post it here.
