Speaking of saving energy in the shower, I've seen an interesting gizmo for that [1]. It addresses the problem of wasted hot water when people get involved in other things while they are waiting for the shower to warm up. They turn on the hot water, and then go shave or brush their teeth or start the coffee maker or check email, or whatever, and can waste a lot of hot water between the time the shower has warmed up and the time they return to take their shower. This gizmo senses when the water has warmed up, and then restricts the flow down to a trickle, until you pull the switch to restore the flow. The change from full flow to trickle acts as a signal to tell you the shower is ready, and the trickle wastes much less how water than the full flow does.
