More tires spun, less gas used up. That's what the EIA has calculated for the American population in 2015 compared to 2007.

Low gas prices mean that US drivers put more miles on their cars in 2015 than ever before. 987.8 billion miles in the first four months, to be exact.

A new study from the US Energy Information Administration makes the interesting finding that as the number of vehicles in a household's fleet increases, the miles driven on the primary car go up as well.

It's not hard to understand, when gas prices go up, Americans sometimes drive less on national holidays. This year, though gas prices are lower than they have been right before Labor Day since 2010, and that means the American Automobile Association (AAA) is predicting that the number of people taking a road trip of more than 50 miles is expected to rise compared to last year. AAA sa

In some ways, taxing people for the miles they drive makes sense. After all, we need money to keep roads in good shape and it already happens today, indirectly, through gasoline taxes. But when anyone talks about taxing the miles directly – i.e., through a mileage or "vehicle miles traveled" tax – hackles get raised.

Because nothing says environmental sustainability like a per-mile tax on electric vehicles.

The price of a gallon of gasoline has been a major downer so far in 2011, and data shows that it may be affecting driving habits. According to The Detroit News, the Federal Highway Administration claims that Americans drove 1.453 trillion miles in the first half of 2011. That's down 1.1 percent compared to the first six months of 2010, or an eye-popping 15.5 billion fewer miles compared to the first half of last year. In fact, the government report shows that total miles are down to the

Opting to buy a battery-powered, all-electric vehicle not only frees your vehicle of tailpipe emissions. It also means owners of plug-ins don't have to pay gas taxes, right? Well, for residents of the states of Washington, Oregon and Texas, that sort of depends on whether or not soon-to-be introduced legislation to establish Vehicle Miles Traveled (VMT) taxes for electr

Sweden seems to be experiencing what experts call a backfire effect from the company's rash of green car sales. Swedish car buyers have been snapping up clean diesel and ethanol vehicles in droves thanks to sizable government incentives, but, according to reports, the nation has actually seen its emissions from the transportation sector <

While the debate over peak oil rages on, a new yardstick has emerged: "peak travel."

Deciphering the new vocabulary of the green car movement can sometimes be a real head scratcher. To alleviate as much confusion as possible, we would like to present our readers with a list of common acronyms and what they mean, with plenty of links for more information. If you have some TLAs (that's three-letter acronyms) that you'd like us to add to our glossary, just let us know in the comments.

The estimated number of miles that all vehicles in the U.S. traveled (the VMT) grew by 2.5 percent in September 2009, the highest year-on-year monthly VMT uptick for 2009. The lowest number was negative 3.1%, recorded in January. Overall, for 2009, the number is up by +0.3% (6.7 billion vehicle miles). These numbers are based on the monthly Traffic Volume Trends report from the U.S. Federal Highway Administration. Usually, the number cl
