Which states use the least gasoline? Which ones have the best gas-conservation trends? Probably not who you'd think, at least for the latter question.
Based on Federal Highway Administration data covering 2001 through 2003, residents of New York State use the least gasoline, person for person, of any U.S. state: about 0.8 gallons per person per day, vs. the national average of 1.2 gallons per person. That's to be expected: New York City--which makes up a sizable chunk of the state's population--is among the densest cities in the country, which allows many of its residents to get by perfectly well without cars, except for the occasional taxicab.
The runners-up to New York were: Hawaii--with high priced gas and surprisingly dense Honolulu--at .9 gallons per person per day; Rhode Island--dominated by urban Providence--at one daily gallon per capita; and Illinois--which has a significant share of residents in urban Chicago and its dense inner suburbs--with 1.1 gallons. Oregon, Washington, and Idaho rank 8th, 12th, and 17th, respectively, in per capita gas consumption; but all three states are close to the national average.
The states that use the most gas are either predominantly rural, have particularly sprawling cities, or both. Wyoming residents use the most gasoline (1.8 gallons per person per day), followed by residents of Georgia, South Carolina, and Vermont at about 1.5 gallons per capita.
Now, for the trend lines -- over the long term, which states are going in the right direction? If you guessed Nevada, you hit the jackpot.
