By some estimates, the country can export 500,000 barrels a day. The increase in global supply begins just as the lowest U.S. gas prices for a gallon of regular hover above $1.30 in some parts of the country. The current national average is $1.90. As crude collapses toward $25, gas prices are on their way down, again.

According to the post, the West Coast is the only region of the country where gas is still above $2, it sits at an average of $2.63 per gallon. The EIA explained the higher prices are not atypical.
