But yes, I do agree that ‘sooner or later’ we will be out of oil. However, with new technologies, in development presently and those we have not thought of yet, there may still be oil in the ground untapped due to no one wanting it for any purpose. And natural gas reserves go out much further then oil reserves do, and power plants are converting to gas… and nuclear for future use.
Michael David, it is a mathematical certainty that Earth cannot support an infinite population of squirrels, elephants, humans, salmon, fungi, condors, oak trees, or any other species. At some point all species reach ZPG --zero population growth – although most bounce around in some zone of equilibrium, rising and falling as food supply varies from year to year. Humans too will reach equilibrium, I hope with as little suffering as possible.
Look at oil demand this way (calculated by Doug50):
It’s estimated the current world uses 1000 barrels of oil per second, or 1000 bbl x 86,400 seconds in one day = 86,400,000 bbl of oil used by the world in one day.
86,400,000bbl / 15428bbl = 5,600 Olympic sized pools of oil used each day.
5,600 pools x 365 days in a year = 2,044,000 Olympic sized pools of oil is use by the world in one year.
At present we have no plan for how to replace this volume of oil to support 6.7 billion people. We are now at peak production, and it would seem we must either find some source to replace the energy that will no longer be available when this oil disappears, or reduce our usage accordingly over the coming decades. Can we do it?
