Lots and lots of good stuff on this issue at www.dieoff.org
IMO, an energy shortage is inevitable in the next decades or less, and will certainly result in a great deal of upheaval. We should be preparing for this now, but in the US, as in most places in the world, those that can do something about it are too busy enhancing there own bank accounts, or walking on eggshells so they can be reelected (preparing for winter in the summertime isn’t usually very popular with the electorate it seems). I’m personally not confident in the human species’ ability to mitigate an oil crunch – we aren’t farsighted enough, perhaps by our nature, and by the time the first real shockwaves of shortage hit, it may well be to late to deploy alternative methods of energy collection – infrastructure can take years to construct or otherwise establish, anarchy can happen overnight.
In a world where there is a greater demand for energy than supply…
How would the US react if Canada, or Venezuela, or a major exporter (or cartel of exporters)… decided to conserve its resources for its own citizens?
How will people in developed nations react to lowering their standards of living (perhaps substantially and quickly)?
How will citizens of 3rd world nations ever expect to reach the levels of wealth enjoyed by their brethren in the industrialized world?
How many oil rigs can be sabotaged or destroyed before the effect on the world oil market is felt?
I think there are lots and lots of ramifications to even a mild, permanent oil deficit, and most of them have not even been explored.
Meanwhile, many places that are currently net oil exporters are experiencing huge population growth rates, thanks largely to outdated societal influences. More people means these nations will be sending less and less fuel abroad, hastening the point where falling supply meets rising demand for everyone else.
I’m glad I don’t have children!
BTW, I hope I’m wrong and the optimists are right. But if not, at least I and the rest of the naysayers will have vindication.
