01.TV energy label

Please note: this information was current as of January 2009 but is still a useful guide to today's market.


Sharp has recently released a 94cm LCD TV, the LC-37D85X, with an energy label – the first of many to come since the federal government mandated that all TVs must have energy ratings by April 2009 and any with a one-star rating or less will be banned from sale after October 2009.

Labelling schemes are only useful if the information on them is accurate and easy to understand. CHOICE is happy to report that the LC-37D85X performed almost exactly as described on its energy label, but at three stars there’s still room for improvement.

The TV uses about 142 watts which is about what we’d expect for a screen of this size and resolution. Our previous TV energy testing suggests that higher resolution is aligned with higher energy use, but hopefully manufacturers will now have a greater incentive to find ways to reduce energy use across the board.

How does it work?

Energy rating stickerThe TV energy labels work in much the same way as energy labels for washing machines and refrigerators:

  • More stars means greater efficiency.
  • If the TV gets less than six stars it carries the label, right.
  • TVs with seven or more stars get an extra star panel on top.
  • The most important factor is the actual energy used, which is calculated based on 10 hours use per day over 365 days. This includes energy used when the TV is on standby during the other 14 hours of the day.
  • These figures are based on the TV being in its “Home/Normal picture mode” setting. Where possible, by reducing the brightness and backlight intensity, you may be able to reduce the television’s power usage even further.
  • In Australia, the energy use of TVs and associated products is on the increase. It’s estimated that it will be more than double the 2005 estimate of 100 watts by 2020.
  • Minimum energy performance standards, so called MEPS, are one way to help keep this increase in check.

In future we will be energy testing every TV we purchase, checking to make sure they have accurate labels you can trust.
