Last month, the Energy Department almost doubled its long-term oil price forecast. That means gasoline prices will continue their upward trend. At the same time, the signs of global warming are clearer than ever. Simply by choosing the most efficient vehicle in each class, we could cut our average gasoline bill by $510 a year, while cutting carbon emissions more than 30 percent. So whether it's for your pocketbook or for the planet, there has never been a better time to buy a green vehicle.
