[...] When computers sleep or are on standby, there is some minimal energy consumption but it is far lower than when they running in all their glory. Putting our computers on standby is a wonderful habit to develop. Shutting off the monitor is a first step towards lesser power consumption. [...]

Scientific American, which did their own research, agrees with the Wall Street Journal article, as does most of the “expert” research I’ve come across. For the majority of LCD monitors nowadays, black uses more energy than white. This may change as newer models–such as those that use LED backlighting–emerge.

If the internet goes all black, it will make a huge difference in energy consumption because everyone will stop using it. Ever see what happens to your eyes after reading a page of text on a black background?

No thanks, I’ll stick with other more practical ways of reducing energy consumption.

A better tip than Blackle would be to recommend exchanging that fancy screensaver for “blank”, as the fancy screensaver consumes more power by driving all the eye candy instead of letting the CPU & GPU idle. Next, be aggressive about your screensaver delay and monitor standby delays, say 5-10 minutes for the screensaver delay and another 5 minutes before monitor standby kicks in.

@nikkon: Glad it works well for you!
@Arvin: Not all LCD screens have a rest state of ‘always on’. It worked for Nikkon for example.
@Cody: Thanks.
@Sean: Yep
@adobe: It’s meant to be an aggregate effect.
@Boules: I agree it’s a point of contention, but please don’t mistake it for misleading information.

One of the key arguments in favor of black screens is a 2002 research study produced by Lawrence Berkeley National Laboratory entitled “Energy Use and Power Levels in New Monitors and Personal Computers.” The report indicates that “a given monitor requires more power to display a white (or light) screen than a black (or dark) screen.” Indeed, that study reports that black screens consistently require less energy than white screens, regardless of whether the monitor is a CRT or LCD.

Is it possible to create blackle toolbar instead of google toolbar. Does google provided blackle toolbar?

Please, next time don't waste your time and your energy with misleading pieces of information like that tip about Blackie. Even . Nobody has saved any watt due to this false tip, but instead caused damage to his eyes. Stop spreading such nonsense.

Blackie is the most stupid thing.. How long does one wait on a google screen… 2-3s max…. nobody leaves a google home page open ha ha ha

So, in a way, wouldn’t this also be a way to increase the battery life of say, your laptop?

Great tips! I believe there are other sites like blackle that I have come across. Google should implement that feature.

Yeah, Blackie is a complete waste of time for LCD screens, which I assume a majority of users are viewing on now (including laptops). LCD screens have a perpetual light behind the screen, and the liquid crystals activate in different colors to block that light. But the light is always on.

I can’t back up the following, but potentially having all black would actually waste more energy since that would mean that the light was being most blocked?

The Wall Street Journal is wrong. I was originally skeptical that an LCD monitor would use less power to show a black screen. So I used a Kill-a-watt meter and to my surprise I found my 24″ LCD monitor used 43W for a black google page, and 46W for the default white version. Maybe all web pages should have black backgrounds.
