I think it has more to do with perceptions that Saudi Arabia oil production has peaked or just about peaked which would be a very strong indication that world oil production has peaked or is very close to peaking. Which means our economy is only going to grow increasingly weirder and I don't mean that in a good way.
I strongly suggest reading
The Party's Over by Richard Heinberg or viewing the DVD
The End of Suburbia to get a firm grasp of the consequences on world oil production peaking.

Oil, War, and the Fate of Industrial Societies
By Richard Heinberg
Foreword by Colin J. Campbell
The world is about to run out of cheap oil and change dramatically. Within the next few years, global production will peak. Thereafter, even if industrial societies begin to switch to alternative energy sources, they will have less net energy each year to do all the work essential to the survival of complex societies. We are entering a new era, as different from the industrial era as the latter was from medieval times.
In The Party's Over, Richard Heinberg places this momentous transition in historical context, showing how industrialism arose from the harnessing of fossil fuels, how competition to control access to oil shaped the geopolitics of the 20th century, and how contention for dwindling energy resources in the 21st century will lead to resource wars in the Middle East, Central Asia, and South America. He describes the likely impacts of oil depletion, and all of the energy alternatives. Predicting chaos unless the U.S. -- the world's foremost oil consumer -- is willing to join with other countries to implement a global program of resource conservation and sharing, he also recommends a "managed collapse" that might make way for a slower-paced, low-energy, sustainable society in the future.
More readable than other accounts of this issue, with fuller discussion of the context, social implications, and recommendations for personal, community, national, and global action, Heinberg's book is a riveting wake-up call for humankind as the oil era winds down, and a critical tool for understanding and influencing current U.S. foreign policy.
