Mark Ontkush wrote on his eco-blog an article about the energy consumption of a computer screen. According to his research, a white computer screen consumes 74 watts of energy, while an all black page uses 59 watts. So he calculated how much energy can be saved if Google turned into Black. Taking in account their huge number of page views (about 200 million queries a day), 750 mega watts/hour per year would be saved.
As a reaction to this article Google created a black version of its search engine, called Blackle. It has the same functionalities as the standard version, but with lower energy consumption.
It's a cheap and fast way to create a buzz and to further differentiate versus their main competitor Yahoo.
I've checked on BlugPulse from ACNielsen and since the launch (April 2007), there have already been 558 blogs talking about the tool with a firm peak in July. The result is not huge, but the ROI must be positive.
