New, standard refridgerators operate with 40-60% less energy than models prior to 2000. The average cost of a new refridgerator is $1,100 — a significant investment, but one that can pay for itself within a few years ($100-$200 a year) if your current refridgerator is from the 1990s.
However, if your current refridgerator model was manufactured after 2000, the likely energy cost savings will be between $5-$20 a year. Unless you are already replacing a broken refridgerator, upgrading to a newer model in this circumstance is likely not going to yield significant energy cost savings.
TIP: Still looking to increase the efficiency of your refridgerator from the 2000s? Do the following:
- Make sure your refridgerator temperature is kept between 37-40 degrees
- Make sure all food kept in your fridgerator is covered — moisture from uncovered food can cause the compressor in the refridgerator to turn on more often
- Avoid leaving the refridgerator door open too long, or opening it unnecessarily. This will decrease the energy the refridgerator may need to maintain a consistent temperature inside the appliance
New Energy Start dishwashers can use up to half of the water older standard dishwashers do, saving homeowners money on water heating and operation costs. These dishwashers are also more quiet and can clean your dishes more efficiently and effectively. The average cost of a new Energy Star dishwasher is around $550.
Unless your current dishwashing machine is broken or defunct, you can anticipating similar energy cost savings by practicing good dish washing techiques:
- Only run full loads of dishes to maximize the water and energy used per cycle
- Make sure that your water temperature is set low — approximately 130 degrees
- Soak dishes in hot water in the kitchen sink for a few minutes before loading the dishwasher. This decreases the likelihood of needing to run a second cycle
- Make sure to turn your dishwasher off when not in use
- If you have the option, choose a short wash-cycle time
Do you have a front-load or top-load washer? These two styles of washing machine are a good indication of the age and efficiency of your current washing machine.
Traditional, top-load washers fill with water from the bottom, making more water per load necessary. Newer washing machines have moved to front-load models — using around 50% less water and 37% less energy. The average price of a new, energy efficient washing machine is $750.
If your washer is over 10-years old or is a top-load machine, you can save up to $135 per year by switching to a new, front-load washer — only taking you 5.5 years to make your money back! However, if your current washing machine is already a front-load model, expected energy savings will be lower and it might be in your best interest to wait to purchase a new front-loading wahsing machine until your old one breaks.
Here are some tips to make your current machine more efficient:
- Only wash full loads of laundry, and not partial loads. This will ensure that all of the water filling to the basin of the washing machine is being used
- Soak and pre-treat garments when necessary, and avoid double-washing
- Use warm or cold water if your clothes are not heavily soiled
