Old fridge energy return on investment.
Refrigerator energy consumption old vs new.
I once had an old manual defrost model that used 1000 kwh year which is more than twice what a modern 425 kwh energy star frost free model uses.
A 1990s era refrigerator would swallow 1 980 in energy use.
A mid 2000s era refrigerator would eat up 1 080 in energy use.
A new energy efficient fridge costs around 600 and many states offer rebates of 50 or so.
Bee is increasing the standards of energy efficiency and so the manufacturers like lg.
So if you have old refrigerator then consider it replacing with the new one with 5 star energy ratings.
Over the course of 15 years a 1970s era fridge would eat up about 3 960 in energy use.
Old fridges use way more energy than new ones even if the old one is manual defrost.
2010 five star rating refrigerator is rated as four star in 2020 because of the changes in the star ratings.
Your fridge is one of the most power hungry appliances in your home and depending on its age it may be costing you enough in power every year that a new one would pay for itself in a short time.
This means that if your fridge is currently from 1990 1992 and you are saving 120 per year per the analysis above and the fridge lasts 15 years your total savings would be 1 800 or an internal.
