When people talk about eating more eco-friendly one big question is: "Do I eat organic food that was shipped thousands of miles or eat something less environmentally-friendly but was grown right around the corner?" The same question can be applied to energy. Does it make sense to move clean energy around on the grid or do we want to be, in WorldChanging's word, "Locavolts"? Local, clean energy would be the best, but that's not always an option. So, what would you prefer to use to power up your electric car or plug-in hybrid?
