Does my T.V. use more energy the louder I turn it up?

Question

Sound is an energy, so I was wondering If a T.V. would use more energy when cranked up as compared to when It is muted?

I'm sure if it does use more energy it would be minimally more but I was thinking maybe some sort of resistor is involved and as you turn it up more energy is allowed through but the same amount of energy is used regardless because on mute the resistor would simply burn all that energy meant to create sound. Or perhaps that is only on ancient t.v.'s or maybe that was never the case at all.

So will turning down the volume save me say 5 cents over 10 years?

Answer 1

The best way to save energy is to turn your T.V. off! There's not much good on these days, anyway.

Yes, louder volume does use more energy, but don't worry about it much unless you are using a battery.

Answer 2

yes. the circuitry for producing louder sound volume (using amplifier) would use more energy (current). current is energy consumption.

same principle applies for a stereo system with speakers. 100 W speakers use a lot more energy than 60 W speakers.

Answer 3

Yes, turning the volume down will use less power.

You could save even more by turning the brightness down a bit too.

Turning down color, contrast or switching to mono won't make any difference.

You can probably save a bit by staying on the same channel and not switching around.    

Answer 4

If it's battery operated, yes.  Otherwise, the audio amplifiers are probably class A, so their power draw is independent of the audio level.  The difference is minimal.  When you turn it off, it's still drawing its rated standby power.  Unplugging it would save more power, but that savings is probably more than offset by the decrease in reliability due to the frequent complete power cycling.
