Energy efficient products

I’ve been involved in energy efficiency improvements since the early 90s and have been fascinated by the improvements to the technology, especially in the lighting arena. I remember how traffic lights and exit signs in the 90s slowly started to use LEDs (Light Emitting Diodes). Now these LEDs are starting to replace the ever efficient CFLs and fluorescent tubes in everyday fixtures. However, since many of the manufacturers are new (and perhaps untested in the market for reliability) most folks don’t realize they are available. The Energy Efficiency Working group is looking at many technologies to help folks source great products for their energy saving needs. What products would you suggest they look at?
