No doubt, basic bedroom communities with a lack of transportation options for commuting will suffer with increased energy costs. However, the suburbs that provide a balanced business, commercial, and housing ecosystem and have diverse transportation options to the main destinations outside will actually thrive and prosper.
The simple fact is that not everyone likes nor wants to live in more densely populated areas. Believe it or not, walkability can be nice, but not everyone cares about that.

/ I actually do love visiting downtowns like Boston and San Fran and walking to places.
// Fortunately, my home suburb in the Twin Cities (Eden Prairie) has hundreds of miles of dedicated bike paths to get around...
// ...and my commute to work is within the suburb itself.
/// Economically, it would take a tremendous shock to get me to move away. Perhaps, I'm just lucky to live in the RIGHT suburb! ;-)
