My HDTV Can Help Me Save Energy
I did not know that some of the newer HDTVs had “energy saving” modes. There is a little green button with a leaf on my far away that can save me money. My LG has 5 settings that could shave dollars off your electricity bill each year. Beginning with none and going up to the extreme of turning the screen off after three seconds of use. The manufacturer claims that the strength consumption can be reduced by 25% to 73% but that is not the results that I found.
Of the five “energy savings” settings only three of them will truly be useful in saving electricity. The five settings are: none, minimum, medium, maximum, and off after three seconds. clearly turning the screen off after three seconds will not be functional if you intend to watch anything on your television. Along the same lines the “none” mode which allows the screen to be used at its brightest and without turning on any of the “energy saving” modes will not save any energy. After choosing a mode, the TV shows graphically how much the mode is saving with a 0 to 100% bar, a nice touch to make you feel already better when selecting any of the saving modes. The claimed savings for minimum, medium, and maximum are 25%, 47%, and 73% respectively. But after looking at the actual strength usage by plugging the TV into an electricity monitor showed slightly different results.
The 32″ LCD television uses approximately 90 watts per hour during normal usage. Turning on the energy saving modes dims the screen slightly, depending on the mode, to reduce the strength consumption of the screen. The minimum mode is barely noticeable while reducing the usage to about 3% to 87 watts per hour. The maximum mode dims the screen markedly, though is less noticeable in a darker room, and reduces usage 61% to about 35 watts per hour. While it does impressively cut the strength usage it also reduces the performance of the screen. The medium “energy saving” mode is the happy medium of not greatly affecting the TV’s performance while dropping the electricity required by 27%, down to about 66 watts per hour.
To put that into monetary terms turning on the medium “energy saving” mode will save between $0.5 and $0.12 per month, depending on how much screen is on. My Kill-A-Watt EZ showed that I was using 19.04 kilowatt hours per month (or $0.38) prior to changing any settings. Turning on the medium mode reduce my consumption to 14.35 Kwh (or $0.28) per month. An additional bonus to using the saving modes is that when the TV is turned off it also draws less electricity. The Kill-A-Watt EZ showed the medium mode reduced the consumption to about a continued 0.01 watts, compared to 0.03 watts in normal mode. The screen nevertheless had variances in wattage, having both modes peak at 113 watts usually closest after initially turning the strength on.
already if your HDTV does not have an “energy savings” mode you can nevertheless apply the knowledge to reduce your usage. With a little trial and error you can go into your television’s settings and reduce the brightness and other settings. Using a Kill-A-Watt EZ will make it easier to confirm you are truly cutting the strength consumption and saving money.
Saving money on your energy bill is regularly becoming easier if you know where to look. Finding a little savings here and a little there adds up. Most new electronics have some sort of “green” or “energy saving” mode including HDTVs. A quick hit of a button could save you more than a dollar a year for each TV without affecting performance, in my case 27%, and the same can be done with all of your electronics. Use a Kill-A-Watt, or another electricity monitor, and find out where you can save some money.
