If you're planning to earn some course credits at the local college or university next term, consider taking an online class. By doing so you could eliminate 15 miles on your vehicle per week, and you'd save about $30 in gas expenses over the course of a semester. In addition, you'd reduce your carbon emissions by about 200 pounds.

Currently, more than 3.5 million students are enrolled in online courses, potentially saving up to 35 million gallons of gasoline-a gas savings equal to replacing 145,000 full-size sedans with hybrid cars.
