By 2020, the EIA projects that Americans will consume 15 million barrels of oil per day through transportation. Of that, we will produce only 6 million barrels domestically, with more than a third of those projected to come from drilling in deep water in the Gulf of Mexico. Economically, oil acts as a sponge in the US economy, as rising gas prices soak up disposable income. On May 11, 2010, for example, Americans spent $1.1 billion on gasoline--$239 million more than on the same day a year before, when gas was 62 cents cheaper per gallon.
