If you're like most Americans, you spend at least an hour or two in your car every day just commuting to and from work.

That's not even counting the errands, trips and minor emergencies that pop up all the time. Unfortunately, our vehicles are usually the least efficient aspect of our daily lives, but you can change that easily! Small changes in our transportation habits – like accelerating and decelerating slowly, keeping your tires inflated and driving calmly – can reap big energy savings!
