In December 2012, America no longer was the world's biggest importer of oil. China was.
That's great news for the US! Let the Chinese become the most oil import dependent nation in the world.
America's net oil imports are being driven down by surging domestic oil production, surging substitution of oil by gas, biofuels, and electricity, and surging efficiency of oil usage. The result is falling oil imports and falling oil consumption in the US. That's great medicine for our economy, environment, and national security.
