Again. You've made my point even more valid. Once it's gone, it's gone for a long time. Amazing how the same argument can be debated and folks still are left with the same fact.
those are global numbers for proven reserves. as prices go up, profitability of getting more difficult oil does as well, and were always finding new oil.
canada actually increased its proven reserves of crude by 100 million cubic meters from 2001 - 2005 (statscan)
between tar sands and oil shale, canada and the US has 3.2 trillion total barrels of oil (wikipedia, and confirmed with other sites as best i could)
only a few hundred billion barrels are easily recoverable, and less than that with any degree of profitability...even at 100 a barrel. i cant find accurate numbers on the oil shale, but theres at least as much of it recoverable as there is tar sands...
47 billion of crude in canada (according to stats can)
21 billion barrels of crude in america. (according to several results on google)
canada and america consume 7.8 billion barrels of oil a year (according to the CIA world fact book and a slightly shakey conversion from million barrels a day to barrels a year). thats 12 years to every 100 billion barrels of oil,
canada has enough proven crude to last itself 40 years, if we stop exporting...more because that would be disastorous to the economy.
we can get will into the next century with the tar sands.
america can feed itself for 3 years on its own oil.
between us, we have 8 years of our own oil for our own demand. this is at 2005 consumption.
with oil sand and shale...60 years.
we could get 100 years if we were the only oil consumers, and milked the current reserves of ourself, iraq and saudi arabia.
