Black Google -- save energy - DiscussWorldIssues - Socio-Economic Religion and Political Uncensored Debate

Same search engine, black screen. Claims that the black screen will help save energy -- 750 megawatt-hours a year, in fact -- if everyone uses black Google. Dunno about that claim, but seems like a decent idea. Check it out.

A black KWF would be frightening, but using a "hakama blue" might be interresting.

If you're using an LCD screen, going black actually uses more energy. The LCD backlight is always on, and it requires additional (although minimal) power to then block the backlight from passing through.

Doesn't LCD uses less energy than a CRT?

**qikolax** · 09-20-2007, 01:48 PM

Yes but I think the point is that using Blackle on LCD screens won't save you anything when compared with Google. There was a discussion online about this a while ago; I'll try to dig up the link.

Yes, but you have less pixels lit.

**Vagtlaldo** · 09-21-2007, 12:19 PM

Ok, I am usually all for doing all the little things for environment, but I have a ahard time believing that it would matter that much (the LCD issue has already been brought up).

If you want to have a greener computer then consider not rigging it with four 3,5" drives, two state-of-the-art graphics card and a 1kW power supply

And shut it off when you don't use it.

**FailiaFelay** · 09-21-2007, 12:27 PM

No, you don't. The entire display is backlit at all times, that is how an LCD works. Voltage is applied to the individual pixels to then filter or block the light to create colors. They are always lit, they just don't always allow that light through to you.

And shut it off when you don't use it.

This is the real key to energy savings, and would be quite substantial. Anybody who's worked in a large office knows that the vast majority of users leave their computers on when going home for the day, and a great many of them don't know the first thing about setting it to at least hibernate or sleep after a period of time.

four 3,5" drives,

You're showing your age now, mate...

Eccch.
I remember 9 and a quarter.
Disks as Big as record players, I tells ya!

(Groans)
Back whin I wuz a boy, we din't have no fancy high falutin' flash-drives n' such!

We had 12 an' a half K of memory, and we were happy to have that!

You damn kids nowadays, what with yer gigerbits 'an yer not tasin' bros...

Spoiled rotten sez I! The lot of ye! (Ptui!)

**eljugadordepoquer** · 09-21-2007, 11:12 PM

Haha

Actually, I have seen (and used) older hardware than that. My favorite was being showed an old harddrive that was actually a disk made of some kind of metal with a diameter of 50 cm or so. And it still didn't hold more than a MB or two at most (don't remember).

Fun fact also: At my university, old supercomputers (from the 80's) are used as furniture. I thikn it is actuallythis one: http://en.wikipedia.org/wiki/Cray_X-MP

"Consider yourselves lucky, now you have zeroes and ones, back in my day all we had was zeroes"

Only joking, I remeber our school computers, they didn't have a hard drive, just a 3'5" slot for a diskette, we use to lead the OS at boot up. Couple of years later we got hard drives, they were the size of a small van and made the tables rattle.

Not to mention my ubercool Sincalir Spectrum, what a little beast that was

Ah, the old days...

10 INPUT A
20 INPUT B
30 LET C = A + B
31 ...Afterthougtht...
40 PRINT C

Who needs Object Orientation and fancy IDE's with source control?
