Help guide to make decisions about whether or not to renew the refrigerator and whether it should be efficient or not. Based on actual consumption data for a two-person household*.
TABLE DATA
| FRIDGE CATEGORY | KWH/DAY | YEARS WORKING | COST OF RENEWAL |
| 5 years old efficient | 0.6 | 5 | 600 |
| 15 years old inefficient | 1.3 | >15 | |
| Brand new inefficient | 1 | 0 | 500 |
if the old FRIDGE still works
According to thedifference in consumption between the old inefficient and the used efficient one, we calculate the years to get the return on investment as follows:
| ELECTRICITY PRICE | BREAK EVEN IN YEARS |
| 0.30€/KWh | 7.8 |
| 0.15€/KWh | 15.6 |
IF THE OLD FRIDGE STOPS WORKING AND CAN BE RENEWED BY AN EFFICIENT OR INEFFICIENT APPLIANCE
According to the price difference between a brand new efficient bridge and other inefficient, we calculate the years to get the return on investment as follows:
| ELECTRICITY PRICE | BREAK EVEN IN YEARS |
| 0.30€/KWh | 4.5 |
| 0.15€/KWh | 2.28 |
OBSERVATIONS
A household that has an old inefficient fridge will need between 7 and 15 years to get a return of investment if they decide to renew it
It takes between 2 and 4 years to recover the difference in price between a new efficient refrigerator and one that is not.
CONCLUSSIONS
It is difficult for people to make energy efficiency decisions based on the return on investment, only those with plenty of economic resources will do so for ecological reasons, but not economic ones. Same thing happens with EV’s and other things.
That’s all, hope it helps!!! 🙂
