About Star Rating of Electrical Appliances
The more number of stars, the greater the energy savings!
The number of stars tells you how efficient the appliance is and the number tells you how much actual energy the appliance is likely to use in a year. The example below is for Australian/New Zealand energy labels
When purchasing new electrical appliances, in particular air conditioners and fridges/freezers, it is important that you compare the star ratings and choose one that has the most stars.
For example in Tonga, a 3.5 star rating (high efficiency) fridge can save you at least 200 TOP per year on your electricity bill when compared to a 1 star rating (low efficiency) on the same size.
