Pain at the pump – tracking gas prices

Search any news site for gas prices and you are swamped with results.  There are a few sources for getting the data behind the news.  The U.S. Department of Energy provides current gas prices by region in addition to historical prices back to 1994.  To see how U.S. gas prices compare with other countries, use Passport GMID.   The data can be found using search, then select expand the menu for “transport and automotives,” and then select the countries to compare.  The lastest data in Passport GMID is 2010, but the data goes back to 1980.  The international units are in liters.
