Ironically, we converted our toilet to dual-flush before we switched to a low-flow showerhead. Changing showerheads is one of the easiest things people can do to save water and energy. According to the EPA, showers represent 17% of indoor water use. And it’s heated water, too.

This weekend we participated in a weatherization barnraising organized by the Cambridge Home Energy Efficiency Team (HEET). No, we weren’t weatherizing an actual barn; neighbors from all over Cambridge got together to help make two homes more energy efficient. We worked on things all over the houses, from installing aerators and low-flow showerheads to insulating.
