I'm thinking of doing something radical: giving up my daily bath. I could still get clean using the sink and take a bath only once a week. This leads me to an even more radical idea: giving up hot water except for the weekly bath. I had an energy audit which said that if I'm away from home for 4 or 5 days, it makes sense to turn off my electric water heater at the breaker when I leave and reheat the tank when I return. Therefore, if I were going to take a bath only once per week, I could also turn off the water heater and save both water and electricity. Just a thought. Not sure I want to go that far, but the idea is intriguing.
