• Energy Star Refrigerators  Save $5.00 /yr
• Initial Investment $100 +
• Payback time 20 + yrs.
NOTE:
The reason why Energy Star Refrigerators are not economically sound is because you have to buy
higher model numbers in order to receive an energy star on the refrigerator. The higher price paid is
caused by both the extra features in the higher models as well as modifications made to meet energy star
standards.
• Loads 322  264 /yr.
• Most have standard size
• EF = (loads per year) / (annual energy usage)

* Numbers are for Electric Water Heater based on five loads a week at 8.28 cents per Kwh
• This Model Save $13 /yr by:
• No pre-rinsing
• Effective Wash Action
• Energy Efficient Motor
• Sensors determine cycle length & temp.
Note:
Energy Star Dishwashers suffer from the same economical issues as refrigerators. The higher cost is due to
features as well as energy star. Therefore, extra features most likely have to be bought in order to buy an
energy star model.
