I wish this brief primer by Robert Bryce weren’t so convincing. One thing worth remembering:
Fans of energy independence argue that if the United States stops buying foreign energy, it will deny funds to petro-states such as Iran, Saudi Arabia and Hugo Chavez’s Venezuela. But the world marketplace doesn’t work like that. Oil is a global commodity. Its price is set globally, not locally. Oil buyers are always seeking the lowest-cost supplier. So any Saudi crude being loaded at the Red Sea port of Yanbu that doesn’t get purchased by a refinery in Corpus Christi or Houston will instead wind up in Singapore or Shanghai.
