Black colored versions of the popular search engine saving electricity
Eco-IT consultant Mark Ontkush wrote a piece on his blog ecoIron saying a Black colored Google would save 750 Megawatt-hours a year in electricity.
Mark cited EnergyStar statistics showing an all white web page uses about 74 watts to display while an all black page uses only 59 watts. He computed some statistics based on the number of queries per day Google gets (200 million) and concluded there could be some significant energy savings by making a change in the screen color.
Well as now as Treehugger reported an all black Google - dubbed Blackle has emerged. Blackle claims it has already saved over 4,400 watt hours of electricity.
While Blackle appears to be the most organized Mark points out there are several other similar sites out there including Google Black, Trek Black, Spanish Black Google and German Black Google

UGH... you keep hearing about this.... these numbers only matter for CRTs! Sure there are still lots of CRTs out in the wild, but LCD screens are being widely sold with new machines these days and LCD screens don't have an energy savings based on color. All colors cost the same with LCD.
The energy star stats are based on old assumptions about what is on people's desktops.

There are around 22 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/

Well if anyone is Truly interested in Saving Energy you will like this site. It says you can save upwards of 25% on your electric bill. At your home or business. Their Lighting manager for businesses even guarantee 20% or refund. If your company can save some money then they may lay off less people. I hope, I’m an optimist.
