I've been meaning to blog about Blackle for months, and finally with a bit of free time (and jet lag) I finally can.
Blackle was brought to my attention when I was travelling round London and a couple of guys on the tube were talking about an "energy saving search engine". At first I tried to figure about how it would work, and then decided to find out more about Blackle over a Starbucks Gingerbread Latte (very good and only available over Xmas - try one!).
Blackle is powered by Google Custom Search, but provides results against a black screen with white writing, so as to save energy. Great idea.
According to ecoIron, a white web page uses around 74 watts to display, whilst an all black web page uses around 59 watts. Depending on the level of usage, the Blackle team hope to save 750 Megawatt-hours a year.
As I write this post Blackle has saved 328,314.890 Watt hours. Good work guys!
Each time Blackle is loaded vs another search engine, you save energy. Whilst this is good in theory, I doubt many will step away from the main Google search engine.
