TVs and monitors shouldn’t be overlooked.
When it comes to saving money and energy at home, a large, inefficient TV or computer monitor could be one of the biggest electricity users in your home — using even more power than your fridge.

Why consider efficiency
-
Immediate running cost savings — Your monthly energy bills will drop if you make the switch to a more energy-efficient TV or computer monitor.
-
Long-term cost savings — The long-term cost savings over the life of a TV or monitor often balance out the in-store savings of buying a cheaper, less efficient model.
-
Better electricity grid stability — More efficient screens require less power to operate. Pairing them with other energy-efficient appliances in your home helps lower electricity demand and places less strain on the electricity system at peak times.
-
Lower emissions — Switching to a more energy-efficient monitor or TV cuts your electricity-related emissions and helps New Zealand reduce its reliance on fossil fuels to support long-term environmental benefits.
Since 2002, around $2.6 billion of national benefit and 3.95 million tonnes of CO2 have been avoided by selling more efficient products and appliances in New Zealand and using regulations to remove the worst ones from the market.

Choosing a TV or monitor
From resolution and screen size to energy efficiency, there's a lot to think about when finding a new TV or monitor.
- Consider your space — The ideal TV size and resolution will depend on how far from the screen you will sit. Also, keep in mind that screens look smaller in-store than at home.
- Compare energy use — Some TVs use more than three times as much electricity as an efficient model of the same size. This means more emissions and up to $600 more in running costs over 8 years.
- Look for more stars — The Energy Rating Label shows which TV or monitor uses less energy and costs less to run.

Understanding the labels
Energy Rating Labels help you compare the efficiency and running costs of similar appliances.
The star rating of an Energy Rating Label won’t tell you how much an appliance will cost to run — just that it will be cheaper than similar sized models with fewer stars.
The trick is to look at this along with the annual energy consumption on the label, measured in kilowatt-hours (kWh). The lower this number, the less it will cost you to run — regardless of machine size.
Find the right TV, monitor and home entertainment equipment
The best TV and computer monitor on the market will look different for individual households.
Screen size and resolution impact efficiency and running costs. Also, consider your space — how far away you sit affects the ideal screen size.
