 Residentail energy savings 
In the latest edition of RMI Solutions, the journal of the Rocky Mountain Institute (see an earlier exhalations entry), there's a short article on retrofitting an older home using energy efficient technology. For supplemental light in dark areas of a home, Solatubes are a unique solution. They are much less expensive than sky lights. A Solatube is a small tubes with a light collector installed on the roof. Light is reflected into the house and a diffuser projects it evenly throughout a room.

Other measures were installing insulated doors with double-paned windows, and Energy Star Appliances used to replace older ones. Small steps that we can all take to save energy. RMI Solutions is available online in PDF.
