Peak Oil

I have been looking at some articles discussing the theory of peak oil. It hypothesizes that after we use half of the world's oil, then we will see production decrease and prices increase as we try to squeeze out the last half. It seems logical. The main point of argument is when we are going to reach that point. Some people think we are there now. Other say it is not far out. However, people live like it won't be met within their lifetimes. We have discussed some alternative energy sources before, and the general concensus is that there isn't anything that can replace oil right now. So what would you do if the shit hit the fan next year? Gas is 9 bucks a gallon, home heating oil is absurdly expensive, airlines start to shut down en masse due to prohibitively high fueling costs. I just ordered a book called The Long Disaster that discusses what this new world would look like. I know it is kind of sick and twisted, but I am the kind of person that looks forward to these major world changes. Am I the only one?
