I posted, roughly two years ago, how the United States had so much fuel as to last a 'very long time'.

I provided amounts, years it would last, and more.

Today I was vindicated by an energy think tank.

First a language lesson

Recoverable means oil that can be obtained (still using formulas from before fracking btw)

Proven reserves are those reserves claimed to have a reasonable certainty (normally at least 90% confidence) of being recoverable under existing economic and political conditions, with existing technology. (Still not covering fracking due to newness of the method)

The amount of oil that is technically recoverable in the United States is more than 1.4 trillion barrels, with the largest deposits located offshore, in portions of Alaska, and in shale in the Rocky Mountain West. When combined with resources from Canada and Mexico, total recoverable oil in North America exceeds 1.7 trillion barrels.

To put this in context, Saudi Arabia has about 260 billion barrels of oil in proved reserves. For comparative purposes, the technically recoverable oil in North America could fuel the present needs in the United states of seven billion barrels per year for around 250 years.

Proved reserves of natural gas in the United States and throughout North America are enormous, and the total amount of recoverable natural gas is even more impressive. The EIA estimates that the United States has 272.5 trillion cubic feet of proved reserves of natural gas. The total amount of natural gas that is recoverable in North America is approximately 4.2 quadrillion (4,244 trillion) cubic feet.

Total supplies of natural gas in North America dwarf those of other countries. 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.

With respect to total recoverable resources, however, North America
