The old freezer or bar fridge in the garage is a surprisingly hungry electricity user. Turn off fridges and freezers until you might need them such as for family gatherings or parties. If they are more than 10 years old, they will use a lot more power than newer, energy efficient fridges and freezers. Maybe you’d think twice about having a bait freezer if you realised how much it was really costing you in power.

You can buy a power meter for around $20 that you can plug between your appliance and the wall point that will give you a power usage amount for that appliance. It is interesting to see what your various appliances use and get an idea of who the real culprits are.
