If the demand were there, could enough veggie oil be produced to make biodiesel a significantly viable option to the mass of autos?
Yes. An in depth answer to this question can be found in our book. Basically, we can make biodiesel from other sources such as one fast-growning, naturally occuring strain of algae. But even in Germany, there is enough biodiesel produced to offer the fuel at over 800 service stations across the country.
