“Given our fossil-fuel dependent economies, this is more urgent and has a shorter time frame than global climate change,” says James W. Murray, UW professor of oceanography, who wrote the Nature commentary with David King, director of Oxford’s Smith School of Enterprise and the Environment.
The “tipping point” for oil supply appears to have occurred around 2005, says Murray, who compared world crude oil production with world prices going back to 1998. Before 2005, supply of regular crude oil was elastic and increased in response to price increases. Since then, production appears to have hit a wall at 75 million barrels per day in spite of price increases of 15 percent each year.
“As a result, prices swing wildly in response to small changes in demand,” the co-authors wrote. “Others have remarked on this step change in the economies of oil around the year 2005, but the point needs to be lodged more firmly in the minds of policy makers.”
Peak oil is the point in time when the maximum rate of global petroleum extraction is reached, after which the rate of production enters terminal decline.
This concept is based on the observed production rates of individual oil wells, projected reserves and the combined production rate of a field of related oil wells.
The aggregate production rate from an oil field over time usually grows exponentially until the rate peaks and then declines—sometimes rapidly—until the field is depleted.
This concept is derived from the Hubbert curve, and has been shown to be applicable to the sum of a nation’s domestic production rate, and is similarly applied to the global rate of petroleum production.
Peak oil is often confused with oil depletion; peak oil is the point of maximum production while depletion refers to a period of falling reserves and supply.
metaphor of the giving tree, the tree being earth's oil and the boy representing humanity...
The Giving Tree is a tale about a relationship between a young boy and a tree. The tree always provides the boy with what he wants: branches on which to swing, shade in which to sit and apples to eat. As the boy grows older, he requires more and more of the tree. The tree loves the boy very much and gives him anything he asks for. In an ultimate act of self-sacrifice, the tree lets the boy cut it down so the boy can build a boat in which he can sail. The boy leaves the tree, now a stump. Many years later, the boy, now an old man, returns, and the tree sadly says: "I'm sorry, boy... but I have nothing left to give you." But the boy replies: "I do not need much now, just a quiet place to sit and rest." The tree then says, "Well, an old tree stump is a good place for sitting and resting. Come, boy, sit down and rest." The boy obliges and the tree was very happy.
Easter Islander's chopped down their tree's to make statues..to the point that the island's carrying capacity to support the islander's population collapsed.

Collapse: How Societies Choose to Fail or Succeed This book employs the comparative method to understand societal collapses to which environmental problems contribute. My previous book (Guns, Germs, and Steel: The Fates of Human Societies), had applied the comparative method to the opposite problem: the differing rates of buildup of human societies on different continents over the last 13,000 years. In the present book focusing on collapses rather than buildups, I compare many past and present societies that differed with respect to environmental fragility, relations with neighbors, political institutions, and other "input" variables postulated to influence a society's stability. The "output" variables that I examine are collapse or survival, and form of the collapse if collapse does occur. By relating output variables to input variables, I aim to tease out the influence of possible input variables on collapses.

What caused America to go from being a leading exporter of oil to the world's largest importer? What are the economic and sociological forces that have contributed to that change and impede its solution?
GAS HOLE is an eye-opening documentary about the history of oil prices and sheds light on a secret that the big oil companies don't want you to know – that there are viable and affordable alternatives to petroleum fuel! It also provides a detailed examination of our continued dependence on foreign oil and examines various potential solutions -- starting with claims of buried technology that dramatically improves gas mileage, to navigating bureaucratic governmental roadblocks, to evaluating different alternative fuels that are technologically available now, to questioning the American Consumers' reluctance to embrace alternatives.
Narrated by Peter Gallagher, hear from a wide range of opinions from representatives of the US Department of Energy Representatives, Congressional leaders both Democrat and Republican, Alternative Fuel Producers, Alternative Fuel Consumers (including actor Joshua Jackson), Professors of Economics and Psychology and more. Anyone who buys gas should see this film!
This could be the year the National Ignition Facility (NIF) finally lives up to its name. The facility, which boasts the world’s largest laser, is designed to trigger fusion by imploding a target pellet of hydrogen isotopes, thereby releasing more energy than will go into the shot. NIF’s managers think that the end of their two-year campaign for break-even energy, or ‘ignition’, is in sight. “We have all the capability to make it happen in fiscal year 2012,” says Ed Moses, director of the US$3.5-billion facility, at the Lawrence Livermore National Laboratory in California.
A good lecture on the future of energy where we'll be socially, environmentally, and economically..(from a longer lecture posted underneath)
What Will Turn Us On in 2030? Where Will We Really Be in 2030?
What Will Turn Us On in 2030? When Will the Age of Big Oil End?
Billions of dollars each year are poured into the development of solar, nuclear, biological, and other energies to substitute for fossil fuels.
But so far, issues of cost, efficiency, and scalability call into question the arrival of the next era of energy. Can any alternative sources become viably competitive with fossil fuels? What can we -- as individuals, businesses, and governments -- do to accelerate the rise of clean energy?

In this video, Paul Roberts talks with Lissa Morgenthaler-Jones, Peter Diamandis and Anthony Tether about Big Oil's future prospects.
All of us have some sort of "philosophy of life," even though we may not have verbalized it. Here you can get ideas for your own philosophy of life. You can see what others think of your own philosophical ideas, and you can help others to become clearer in their own thinking.
When there is difference of opinion, we have an opportunity for "friendly debate," a very growth-promoting experience.
