My 30 year old refrigerator uses about $9 worth of electricity per month. If I bought one which was twice as efficient, I’d save about $55 a year. That’s a 20 year payback (neglecting lost investment opportunity) for a $1100 model, plus the replacement hassle. So, I expect to run it until it breaks.
