Conumer Reports Money Advisor had an interesting article on how long it takes for replacement appliances to pay for themselves on energy savings alone.
The article assumed 20 year old appliances and compared refrigerator, washing machine and dishwasher. Only the refrigerator could pay for itself in 7 years, the rest took longer.
Who would have guessed?
I wish they had added furnaces and water heaters to the mix. From what I've read the two of them consmer the vast majority of household energy.
Have a wonderful day,
PS Since our house is new, I'm very curious to see what our energy bills are.
