Are bio-diesel cars really more earth friendly?

Yes they are more earth friendly because you are using a by product instead of constantly relying on foreign oil, which most of the US does. This can save you and your county money, to help save the earth, and most bio diesel use recycled so even further savings.

No unlike electric cars, bio-diesel are friendly to the environment. They do still consume come petroleum based diesel fuel but only a small amount when starting up. From then on the run purely on waste oil. This oil burns cleaner and helps engine run longer. So bio-diesels keep waste oil from being thrown away and reduce diesel emissions.
