In the Long Emergency schooling will be required for fewer years, and children may have to work part of the day or part of the year. Because everythi… - James Howard Kunstler

Both the mining and the washing [of hydrocarbons] require huge amounts of energy, and it has been proposed that any commercial exploitation of the Alberta tar sands would take 20 percent of Canada’s total natural gas production. In the long run, it might not be worth expending the energy from gas to get the energy from the tar sands. If oil from the tar sands themselves were used to process more tar sands, the return would be three barrels of oil for every two consumed. […] In the early days of conventional oil in Texas, the formula was very favorable, around twenty to one. The oil was found close to the surface on dry land in temperate places easy to work in, and it gushed out of the ground under its own pressure. […] Going a bit further, the fundamental equations that support all gigantic… organisms, …may no longer obtain, and human life would have to reorganize its activities on a different basis. Also, once these complex systems and their subsystems halt their operations, restarting them may range from difficult to impossible […].

I don’t think the previous Dark Age that followed the collapse of Rome was quite the same as what we’re facing. That involved a profound and incremental series of losses in knowledge, technique, and the ability to do things, everything from making good pottery and concrete to ways of organizing work. Our situation now has much more potential for cultural damage, because our conditioning in technological progress is so extreme. The letdown may be awful when it becomes evident we’re not going to solve our energy problems with algae secretions, solar, wind, or other alternative fuel schemes–that we’re not going to run [high-energy things like] , the , , and the military on any combination of other energy systems. […] This has enormous potential for disrupting our sense of reality. It’s hard to predict the kinds of reaction[s] that this may generate, but I think you will have a society so profoundly disappointed by science and technology that it could propel us into a new dark age of superstition.

[…] With China becoming a presence by necessity in the region, we would be back in a cold war again, or something worse, contesting with a rival world hegemon, this time over… resources, not [just] ideology.
