This week at TreeHugger: Ready for your first electric vehicle? A look at what's out there for the TreeHugging American, the birth of the Tesla, and a view of things to come. The EVs are also laid out at this year's London Auto Show. For the more vegetable-inclined, we have the skinny on running straight vegetable oil and brewing biodiesel, as well. And, if the nimble and gas-sipping Smart Car is really coming to the States, adding an extra motor and tires the size of tool sheds is a fitting right of passage, wouldn't you say?
