The End of Suburbia is one of the classic, and also one of the first "Peak Oil" videos. It came out in 2004 and in its day was (for a lot of people) really new information that shattered a lot of people's exsiting views on reality. Even now it is still capable of doing that if you are new to this kind of thing.
The End of Suburbia is shown as a single YouTube video segment.
