There is comparable data for natural gas. At present, the U.S. has 272.5 trillion cubic feet of proven natural gas reserves, but the total for all of North America is 4.7 quadrillion. At the current consumption rate of 24 trillion cubic feet annually, there is enough natural gas under Canada, Mexico and the U.S. to last 175 years. To put that in further perspective, IER estimates that “the United States, Canada and Mexico have more technically recoverable natural gas resources than the combined total proved natural gas reserves found in Russia, Iran, Qatar, Saudi Arabia and Turkmenistan.”
Data like these make it clear that America's biggest problem on these issues isn't that it's impossible to “drill, drill, drill,” but rather that the president, his appointees at agencies like EPA and the departments of energy and interior, and his Democratic allies in the Senate refuse to deal with the world as it is instead of how they wish it could be.
