To expand on cooker's comments, may I suggest this article:

I think it's an important read, because most people just think of transportation when they think about oil availability. It goes far beyond that. We depend on fossil fuels for just about everything that sustains our lives. As we pass peak oil and natural gas, I'm afraid that we will be totally unprepared for the implications. I'd love to see us making choices and taking actions to avoid a catastrophic collapse, but I don't see that happening.
