the theory of black google could save energy because they have a large user base is interesting.
the web site says that monitor displaying black colour is  using the least amount of energy.
influenced by the statement ,I changed my desktop appearence to high contrast black
now i have problem writing this post

i'd just set my monitor to turn off after 10 mins of idle, or turn off the machine alltogether when not using it. the power usage on a modern pc is similar to having all the lights on in your house

but if you do the maths and inlcude idle times total wattage isnt that much really a pc draws typically 150 - 200 watts at max usage even if the psu is rated at 500 watts it NEVER REALLY draws 500 watts!

even a CRT monitor typically draws 25 watts with LCD screens drawing considerably less!

totalled you will be using around 200-250 even using 16 hrs a day you will not be drawing huge amounts watt for watt!

remember we are talking watts here as in LIGHT BULB WATTS a typical bulb is 60 - 100 watts .... not KILOWATTS as in KETTLES yes your electric kettle can draw as much as 3 KILOWATTS yes thats 3 WHOLE KILOWATTS and how many coffees/cups of tea do you have per day ??

It soon adds up

Yeah, leaving a computer idle does not use THAT much juice.  Especially with the monitor off.  I'm playing video and formatting a drive right now and am pulling about 250.  I imagine it goes much higher while using 3d video...

To add I rarely Turn mine off with the exception of installing new hardware .... in fact a computer works best at an ambient temperature and to turn it off could be more harmful than to actually leave it on or in standby as the board can be subject to THERMAL SHOCK by suddenly cooling down the board It can/could crack/damage the board altho this is a rare thing to happen It has happened to machines I have had to repair or check out for people

yes, all very correct.

my bulbs are around 11 watts, but the point was that you wouldn't leave all your lights on if there wasn't anyone in those rooms so why leave the computer on when it's not being used.

even if you consider your carbon footprint to be small there are probably many who think the same but don't realise the net effect, which is really what blackle is trying to illustrate.

so what color is your desktop theme? that black too?

what about your mouse pointer every little helps I guess lol

I see your point but .... for this to work EVERYONE in the world ie the BILLIONS of us out there would have to adopt the same stance and use blackle or for GOOGLE themselves to adopt it as its own page color along with the millions of others that use MSN as their search engine and those that use YAHOO,EXCITE,DOGPILE, etc etc etc it just wouldnt work ... for me its just a gimmick for people to use someones custom google page which happens to be black!

My computer is used for a lot of things even when Im not on it/using it e.g. I do a lot of Video ENCODING, protein folding  (FOLDING@HOME) (decoding protein folding not very exciting but a worthy project)  and also various other stuff

Yes... I recycle and think about global warming but when theres gas guzzling cars/lorrys (I don't drive I cycle/walk!) ......factorys etc out there adding to the carbon footprint my computer being on will be a tiny tiny amount in comparison

..Altho If you read the reports and watched THE GREAT GLOBAL WARMING SWINDLE and a few other documentarys on the other side of GLOBAL WARMING debates you will see that we also had Global Warming in 800 - 1300 A.D. (Medieval times) and also again in mid-Holocene 1600 years ago..

.. How? .. do we account for that when computers and cars and big power hungry factorys NEVER EXISTED!

I can see the Idea behind it but .... would only really work if EVERY PAGE on the internet was also black?

As once you have searched and clicked your found link the page color/status returns to whatever color the web designer has used which in most cases is WHITE! lol

sorry mudlouse1 I just like a good debate

[mudlouse1]

you're going off on a tangent.

nobody mentioned anything about global warming, folding@home or the medieval dark ages.

all i suggested was to a) set your monitor to turn off after idling and b) turn off your computer if not using it.

yes, the aim is to save energy (i don't want to get into this discussion, frankly) but don't you think it's a shame to see things go to waste?

lol yeah I know I go off on one but .... (excluding you mate ) It annoys the heck outta people that seem to think something like a black google page is going to help reduce carbon footprints  (which incidentally is also global warming related hence the tangent )

and yes ..I turn my screen off at night lol so maby I dont need a black google after all lol

yeah I know its a shame hence I recycle landfill sites full of garbage(rubbish) sucks its a terrible waste of resources

[Devil_Spawn]

actually, i find blackle a little easier on the eyes, especially later on, however it isnt integrated into opera, so it just isnt an option for me :p

To get back on to the original posting, I don't see how a black screen can save enery; all TFT/LCD monitors have a back-light in order for you to see the colours of the pixels. Be your sceen black, pink or green the lamp at the back stays the same intensity and it's just the colour combination of black and the 3 primaries that leads to the eventual colour on the screen.

Now, with OLEDs (which are not yet in production with monitors, but are in small displays such as phones and MP3 players) the situation of black Google would work. With OLEDs (Organic-as in chemicals, not food grown without them!- Light Emiting Displays) the pixel either has a current going through it to emit a light or doesn't. In this case, black would be generated by not having a current going through it and so would, in fact, save energy!

At the moment, the best it to get your monitor to switch itself off.

well ,I am skeptical too.
That is the point I posted about it so we can discuss
