Is it true that having dark (black) wallpaper for your computer decreases carbon dioxide emissions?

Question

even at least a bit?

Answer 1

Not sure on that, but I guarantee not turning your computer on will.  Why not give it a try?

Answer 2

wowa, dont think so. each color depicted on ones screen should take the same amount of energy.

if you want to help your environment go plant a tree/ get a house plant or something. they like Co2 you know, and give out oxygen.

ha, didnt mean to sound hippy there, but hey, it helps  doesnt it?

Answer 3

how?

does you computer emit CO2? From the screen??

this is no way possible.

Answer 4

false

Answer 5

really?

i thought only living things respire & liberate carbon dioxide.

its good 2 b computer addicted & luv ur computer.but still ur computer can't come 2 life.NO WAY!

Answer 6

not directly

but it does use more energy as black is an off pixel

so depending on how they produce the energy it could change emissions.

eg coal is literally carbon burning into carbon dioxide gas

Answer 7

if the screen is putting out more light, it must be using more power.

I think the brighter screen bothers my eyes more,too- like sitting too close to a TV, if you think about it. I prefer a dark screen, with the letters lit.

     by the way,  larger screens also use more power. and flat screen's use more than tube TV's  I prefer a small TV, which I can put on a shelf when I'm done with it. TV's also use a little power, even when shut off, unless you unplug it

Answer 8

If you look at your monitor there is no black pixels but the monitor turnes that area off to give the black look.  That area is probly sitting in some sort of idle mode that im sure uses some amount of power though (possibly more?).  It may also depend on what kind of monitor you have(CRT or LCD).

Answer 9

interesting. not sure.

Answer 10

It saves on energy usage. So I guess it will lower your electriciy usage, so a little. Its kind of a stretch, but it is a little.

Answer 11

No, Where did you hear that.

Answer 12

There is a big no no.

Why? Because computer monitor only emitts light with radiation but for years now, much research has been focused around the potentially harmful effects of the extremely low frequency (ELF) electromagnetic fields emitted by Cathode Ray Tubes (e.g., your television at home, or the monitor that you are using to read this document). Some researchers believe that such fields could be attributed to such conditions as leukaemia, tiredness or general fatigue. Others (e.g., Anzovin) state that in general, we are unsure on the biological effects of ELF emissions to know whether they are safe or not. Given this uncertainty, he argues that we should limit our exposure to such fields, and recommends the following precautions to minimize exposure;

Which means that there is no relation such color in your monitor to produce the cArbon dioXide...

Answer 13

wow

Answer 14

True, if you have black surface it does not require energy to make the non existent light.

This is true regardless of monitor type, but most significant with CRT.

You can even cut power usage by turning down the brightness of the screen, and if you have a UPS, turning it off when you are not running the computer cuts power use. (It also cuts the lenght of time the UPS keeps the computer running early in your next session if power fails.)

Of course, if the power grid had no coal, oil, or gas fired power plants, this would not reduce CO2 output. The CO2 output is all from those kinds of power generators.
