The suburbs contain a lot of land and space which is not being put to productive use other than as a living space. I expect as aspects of our modern life decentralise, such as energy, then we will see suburban communities go from sustainable solutions to productive ones.

It will probably not be too dissimilar to how I have adsense on this website. It doesn't make me a living salary, but it does cover the cost of the site. If solar cells could pay the property taxes and so on, then it would be more than useful for most people.

Ironically via the same website that prompted the hostility to suburbia post.
