Bio-diesels are still too inefficient and expensive to make an impact except on food prices. With food prices already rising, comitting such a large percentage of our food sources for fuel would drive up the price even further. Until alternative fuels become cheaper than oil (which may be sooner than later) we'll continue to pay at the pump.
