We suggest you create a Comparison.com.au account so you can save your wishlist for later. You can use your account details to log on to the site from another computer, retrieve your wishlist and continue your research.Â After you buy your model you can visit the site to quickly find the associated user manual and manufacturer web site. Then when you are interested in upgrading, you can compare the newest models against your existing model.

To assist you in selecting an energy efficient television, we list the normal use and standby power usage reported by the manufacturer. These power specifications are used to calculate the Energy Rating,Â however these specifications are subject to change without notice by the manufacturer.Â As Energy Star Ratings for televisions have been introduced, we have moved to reporting the Energy Star Rating rather than our Energy Rating calculation.
Comparison calculates an estimate of theÂ annual running cost for electricityÂ for each model. This is based onÂ the assumption of 6 hours viewing per day and 17 cents per kilowatt. For example a 40 inch screen, with a normal power use of 260 watts and a standby power use of 1 watt will cost approximately $98 per annum to run.
The cost per annum estimate is based on manufacturer specificationsÂ which are subject to change without notice. This estimate is provided as a guide only and your actual costs will vary due to your viewing habits and the cost of electricity from your supplier.
The Comparison NetÂ Energy Calculator provides you an estimate of theÂ energy and greenhouse gas that a particular television model will generate over its lifetime.
To use the calculator simply input the expected lifetime of the television plus your usage habits. The average usage assumption weÂ use is six hours viewing per day however if you are a heavy viewer (or have to fight theÂ kids for the tv)Â this may increase dramatically.
The Energy Calculator then uses three factors to calculate energy consumption and greenhouse gases.
1. The TV’s normal and standby power consumption specification as reported by the manufacturer *;
2. Your viewing habits (the default is 6 hours per day); and
3. An energy emission factor (1.239Â based on the state of Victoria)Â published by the Australian Greenhouse Office.
The calculator generates the energy consumption inÂ kilowatts hours for the life of the television plus the associated greenhouse gases generated to produce that energy.
Calculating the actual cost in $Â to you over the lifetime of a television is harder.
Check your bill or review your local electicity provider’s site to get the latest cost per kilowatt hour.Â Multiple that figure (around 17 cents per kilowatt per hour) by the total kilowatts per hour consumed by the TV.
However the cost of energy is predicted to increase over time as Australia invests to minimise greenhouse gas production from energy. A reasonable assumption would be a 20% increase in costs over the next ten years.
