An all white screen, uses around 74 watts to display, an all black screen uses only around 59 watts. Imagine how much energy would be saved if high traffic sites changed their color schemes. Case in point, Google.
Mark Ontkush wrote about this in his blog entry entitled: “Black Google Would Save 750 Megawatt-hours a Year”. Mark stated Google, gets about 200 million queries a day, assuming each query is displayed an average of 10 seconds, Google would be running an equivalent of around 550,000 hours every day on one desktop. Shifting to the black background would save around 15 (74-59) watts, running into global savings of 8.3 Megawatt-hours per day, about 3000 Megawatt-hours a year. Moreover, at 10 cents per Kilowatt-hour, a whopping $75,000 worth of energy can be saved.
Mark posted this blog in January, a few months and color schemes later, Blackle was born. Even more interesting is Blackle's watt hour savings counter, tracking how much energy is saved using this version over the all white background. Congratulations Marc!

Google came out with their official statement on Blackle yesterday. For flat-panel monitors, especially those marked as "EnergyStar 4.0 Compliant", it may even increase energy usage.

It's been discussed time and time again, a black search portal offers very little in the way of power saving overall. All this site does is generate revenue for it's owners which is put to no good use at all.
As an alternative search portal try -
www.regrowgle.com
Any profits from using this portal are actually put back into environmental projects to cancel out a portion of energy etc that is consumed.
Hey it's a start, and every little bit counts in my opinion
Blackle is just the first page of www.searchincolor.com which has offered google search in color since much longer.
I think black doesn't save much energy-and google officially said that in their blog somewhere-but it is good to have a more colorful internet search experience.

I'm using at the moment BLACKOOGLE, which is similar to blackle but offers a lot more functionality like image search, youtube search, mail access, etc. And looks nicer too, give it a try!

There are around 15 different versions of "black google" online. The best one I've found is www.cleanblack.com. Cleanblack is the only version that allows you to change the text colors of the google search results. Try it yourself by going to www.cleanblack.com/theme/
