10 Jan The higher the rating, the greater the energy savings!
A number of countries have introduced energy performance ratings for household appliances. For example in Australia and New Zealand the energy performance rating is measured in stars on a label put on the appliance. The number of stars shows how efficient the appliance is and also how much energy the appliance is likely to use in a year.
The star rating indicates the energy efficiency of the appliance on a scale of 1 to 6 stars. In this case 3.5 stars.
I t shows the Appliance Type and Model Number and how much energy the appliance typically uses annually in kilowatt per hours (kWh) when tested to the Australia / New Zealand standard.
As an example, a 3.5 star rating (high efficiency) refrigerator with 350 litres capacity can save you about NZ$150 per year on your electricity bill when compared to a 1 star rating (low efficiency) of the same capacity.
