How long does the oil reserves in the world lasts?

There's four times more discovered oil in the ground not being used than this is in currently being drilled.





There's enough oil in the United States that if it were all drilled we wouldn't need to import any oil from anyone.





Next time you see some ******** liberal be sure to thank them for the $3 per gallon gas.How long does the oil reserves in the world lasts?
Estimate coal is about 1 trillion tons, which is about 30 X 10^21 joules 30,000 exajoules of power. This is estimated to be enough for at least a century, and perhaps more.


Estimated oil is about 1 trillion barrels, which is about or 6500 exajoules of power-this will start getting pretty tight in the next 20-50 years


Estimated natural gas is 150 trillion cubic meters, or about 6000 exajoules-this is the hardest to estimate, since not as much work has gone into finding natural gas fields-this will be increasingly more important as a replacement for oil, but is more expensive to transport and store. If the low estimate given is correct, it should last sometime beyond 50 years.How long does the oil reserves in the world lasts?
They last as long as the world allows them to last. Oil is in limited supply so it wont last forever. Thats why we are4 looking for other fuel alternatives!!!
No one really knows, there are probably oil fields no one knows about. Our oil fields may already be depleting. We rely on core samples and readings to tell us about something we can't even see.
The world's oil reserves are limited to 50 or 100 years, maybe less. But to this time other alternative energy sources will be developed and use of petroleum in some areas will be replaced with other alternates.
70 years for US
that is impossible to know if you are talking about the world
