In the long run, however, biodiesel is more expensive than petroleum because the cost of turning raw materials into burnable, energy-producing form is higher than its overall return. Moreover, because biodiesel is typically blended with petroleum diesel, it therefore shares diesel’s harmful emissions and remains heavily dependent on foreign petroleum imports. What’s more, large-scale production of biodiesel requires a considerable amount of cropland, which could have adverse affects on the global food supply as the price of other goods and products become susceptible to a backlash effect.

Fortunately, there is Natural Gas lying around as the only alternative source of energy with the present capability to overcome these hurdles while bringing us closer to sustainable energy independence. Unlike biodiesel, Natural Gas is clean burning with no nitrogen oxide emissions and is suitable at any temperature with no drivability problems due to it solidifying during a severe winter storm, for instance.

Without a doubt, the better alternative that offers cleaner fuel at a reasonable price, and with a wider distribution infrastructure currently in place is Compressed Natural Gas or (CNG.)
