It takes fossil energy to produce biofuels. Fertilizer (Haber process - natural gas) Tractors (diesel) harvesters (diesel) transportation (diesel) pressing (electricity coal 50+% rest hydro, nuc) distillation (fuel oil or natural gas). What is critical is the energy balance in these processes. If they use as much energy (on according to some studies more) fossil energy than they produce, then they INCREASE dependence on foreign oil.

This makes no sense whatsoever. Three of those variables can themselves run on biodiesel. As for the rest, can you explain how using nuclear, hydro, and natural gas have anything to do with foreign oil?

Three of those variables can themselves run on biodiesel

The depths of incomprehension here are sometimes staggering. They could, but they don't because there isn't enough energy left over.

If these fuel sources made us independent from foreign oil, then you could run the whole process on the biofuel as you pointed out. NO ONE HAS BEEN ABLE TO DO THIS. ALL of the biofuel production streams rely on fossil fuel as energy inputs.
