ENERGY STAR is New Zealand's mark of energy efficiency. It's awarded to around the top 25 percent most energy efficient appliances and products in a range of categories. Energy rating labels provide consumers with information on how much electricity an appliance uses in a year, plus a star rating to show how energy efficient it is. The label helps the buyer compare between models and choose the most energy-efficient appliance that suits their needs.

All new white ware and heat pumps available for sale in New Zealand must display an energy rating label. It is important as choosing an energy efficient appliance can save you lots on your power bill, and help the environment. For example, you can save up to 44% on running costs by simply choosing a 5.5 star energy rated heat pump instead of a 3.5 energy rated unit.

TIP 1 - Switch off lights when not in the room. Lighting accounts for around 15% of your energy use. Either use a pre-programmed timer or switch off your lights when out of the room or on holiday.

TIP 2 - Switch off appliances at the wall when not in use. Computers, TV's and other appliances that are never switched off add dollars to your power bill. So rather turn them off than leaving them on standby.

TIP 3 - Keep doors closed. Close the kitchen door when you use the oven and it will heat the kitchen. Keep the kitchen windows closed too. You will also keep the heat in the other rooms that you are heating.

TIP 4 - Insulate your home. Keep warm in winter and cooler in summer by installing wall and ceiling insulation. A well insulated home can be up to 7 degrees warmer in winter.
