Real Gas Prices @ 6-Yr Low = $346 Billion Savings
Using real gas prices from the EIA (in December 2008 dollars), the chart above (click to enlarge) shows how today's gas prices compare to past prices. The last time real gas prices (national average) were as low as $1.69 per gallon was six years ago in December of 2002, and the last time real gas prices (national average) were as low as $1.25 per gallon (current Kansas City low price) was almost ten years ago in February of 1999 (see chart above). Gas prices in Kansas City are within 4 cents per gallon of the lowest-ever (national average) real gas price of $1.21 per gallon in February of 1999.
The $2.43 per gallon drop in gas prices from the peak of $4.12 per gallon in July to the current price of $1.69 represents $346 billion in annual savings for American consumers and businesses (1 penny fall in gas prices = $1.4235 billion annual savings, calculation here).
