Oh, c’mon, man! Have a little faith!
Oh I have faith

. It’s just that my faith in the future belongs to God, and not in some belief that man can solve all of man’s problems. I believe we are at a historical turning point in human history. The 20th centure’s technological advances were made possible by cheap and abundent petroleum. Well, petroleum may still be abundent but cheap is going a way and the ability to get it out of the ground at the rates demanded by the modern world is going away too.
World oil consumption, today, averages 82-83 million barrels per day. Before the recession it was ~87 million barrels per day. The EIA projects global consumption will rise to 118 million barrels per day by 2030. Assuming 85 million barrels per day let’s do a little visualization. What does 85 million barrels of daily oil demand look like, a barrel of oil is 42 gallons? Since everyone knows what a 55 gallon steel drum looks like, I’ll use drums to illistrate:
(85,000,000 x 42 gal) / 55 gal = 64,909,090 steel drums consumed and need to run the modern world.
Since a steel drum is 3 feet tall, how many miles long would a pipeline be if we laid all those drums end to end?
(64,909,090 x 3’) / 5.280’ in a mile = 36,880 miles long. That’s enough steel drums to encircle the earth 1 1/2 times…every day.
Since the volume of oil in this imaginary pipeline is being replaced…every day, how fast would the oil have to travel in a 24 hour period to go from inlet to outlet?
(36,880 / 24hr) / 768mph speed of sound = 2…that is Mach 2 or twice the speed of sound.
At 85 million barrels per day, how many times could you encircle the earth with 55 gallon steel drums in a year’s time?
(36,880 x 365days) / 24,901 mile circumference of the earth = 540 times.
That’s how much relatively cheap oil (a gallon of gasoline produces the equivolent of 500 manhours worth of work for only $2.50) is needed today to feed the mankind and keep the modern world running. Who in their right mind believes mankind will replace even half that volume using renewable bio fuels? I mean, that many steel drums is a heck of a lot of corn oil pumping at mach speeds 24/7 through a 22" pipeline. So if humans are forced to choose between hunger and CO2 I think CO2 will fall on deaf ears.
Now get this: The IEA’s World Energy Outlook 2008 conducted an engineering study to determine the depletion rate on global production. The study was on 800 fields that produce 2/3rd of the world’s oil supply. That’s the sample. Their conclusion was the global oil industry must bring on line the equivolent of a new Saudi Arabia every 5 years just to offset depletion and keep global production at current capacity. However, to not only offset that decline rate but to meet the expected demand increases from developing countries (think China and India) 6 new Saudi Arabias would need to be put on line between now and 2030 - that’s 6 SA over the next 20 years. 20yr / 6 = a new Saudi Arabia every 3.5 years. The next 20 years are going to be a very interesting time to be living in.
