Home - Misc.: Gas Prices
The plot above tracks prices of a gallon of gasoline and of the equivalent amount ("gasoline gallon equivalent," or GGE) of compressed natural gas (CNG) since the start of 2001. The prices for three grades of gasoline are from a Chevron station at Marine and Aviation, south of the Los Angeles International Airport (LAX), that I passed every day on my way to work while I lived in California; the CNG price is from a Clean Energy station two miles north of LAX. At the end of 2007 I moved to Hawaii, but I go back to LAX on business a few times a year, and so I have been able to continue the chart since the move (with a set of dots for every visit, rather than daily tracking as at the outset). You can see that the price of CNG is considerably less volatile than that of gasoline, as well as significantly lower overall.
