"Although the OPEC embargo seemed to provide proof that the world was running short of oil resources, the move by Arab exporters did the opposite: It provided massive incentive to develop new oil fields outside of the Middle East—what became known as "non-OPEC," led by drilling in the North Sea and Alaska."
Forty years ago, on Oct. 17, 1973, the world experienced its first "oil shock" as Arab exporters declared an embargo on shipments to Western countries. The OPEC embargo was prompted by America's military support for Israel, which was repelling a coordinated surprise attack by Arab countries that had begun on Oct. 6, the sacred Jewish holiday of Yom Kippur.
