This one is for those of you who like the details and want to know about green energy and building. Catherine Mohr gives a short TED talk about using embodied energy to calculate the payback time of her new home.
While embodied energy does not take into account all of the sustainability aspects I cover in my ebook - it does present an easy to understand analysis of how to view your choices through a certain lens - that of how much energy goes into the production and transport of materials she's using to build her home. At the end of her presentation, she provides a payback period which is really interesting!
