The Composition of US Oil Production
US overall liquid fuel consumption is currently at 19 million barrels per day. The graph shows what the US is able to produce itself, that is slightly more than 50%. What we see here is 1) crude oil (blue); 2) liquids derived from natural gas (red); 3) other liquids, mainly biofuel, that is corn ethanol (green) and 4) volume changes from cracking heavy oil in US refineries (purple). The graph makes clear that most of the production increase of recent years has come from the non-crude components, with biofuels as the largest source of growth.
