"By prompting President Obama to suspend deep-water drilling in US offshore waters, the Gulf oil spill is pushing up the date at which the world's conventional oil production peaks," says the CSM. "Without alternative supplies of energy to offset it, a decline in oil production would send shock waves through the world, rattling economies and politics alike. Competition for resources could be fierce. In a geological sense, the world is still awash in oil. The US Geological Survey estimates 3,000 billion barrels of conventional crude are buried in the world, about a 46-year supply if no more oil is found, according to the National Center for Policy Analysis, a public-policy research firm in Dallas."
