As the price of fuel continues to rise, this site continues to be as timely as when it first came online in October 1999. The site is maintained by the U.S. Department of Energy's Office of Energy Efficiency and Renewable Energy and the U.S. Environmental Protection Agency and it provides fuel-saving tips, fuel economy estimates, and so on. From the homepage, visitors can click through sections that include "Gasoline Prices", "Gas Mileage Tips", "Hybrid Vehicles", and "New Fuel Economy Ratings". As one might expect, the "Gasoline Prices" area allows users to find the lowest gas prices in their area, learn about saving money and fuel with gas mileage tips, and also learn why gas prices are so high. In the "Your MPG" area, visitors can calculate their own miles per gallon and also compare their measurements with other users. Finally, visitors can also access this information on their mobile phones through a specially designed site that includes fuel economy ratings, fuel cost estimates, and annual petroleum use.
