Regardless of the hyped oil reserves numbers, the U.S. cannot produce enough domestic crude to supply itself independent of imports. This is common knowledge to anyone who has done a modicum of research into the issue (Hannity, Beck, and Limbaugh do not count as research -- to the contrary, in fact).
As to diesel, it burns dirtier than gasoline (particularly with particulate emissions), and biodiesel has less energy content than regular diesel, although thermodynamically diesel is a more efficient internal combustion fuel than gasoline. Again, common knowledge . . . . .
FAME [Fatty-Acid Methyl Ester, perhaps more widely known as biodiesel] has a lower energy content than diesel due to its oxygen content, and as a result, performance and fuel consumption can be affected. It also can have higher levels of NOx emissions, possibly even exceeding the legal limit. [...] The loss in power when using pure biodiesel is 5 to 7%.
