Il motore di ricerca ambientalista ha l'abito nero e si chiama Blackle
(www.blackle.com).
In pratica, invece del classico colore bianco sullo sfondo viene usato il
nero, che farebbe risparmiare ai monitor degli utenti (Google fa circa 200
milioni di ricerche al giorno) qualcosa come 3.000 Megawattora all'anno (su
www.microtech.doe.gov/EnergyStar/info.htm#display potete vedere quanto
consuma ogni colore).
Il sito utilizza comunque il motore di ricerca di Google, limitandosi a
sostituire il classico sfondo bianco con uno nero.
About Blackle:
How is Blackle saving energy?
Blackle saves energy because the screen is predominantly black. "Image
displayed is primarily a function of the user's color settings and
desktop graphics, as well as the color and size of open application
windows; a given monitor requires more power to display a white (or
light) screen than a black (or dark) screen." Roberson et al, 2002
In January 2007 a blog post titled Black Google Would Save 750
Megawatt-hours a Year proposed the theory that a black version of the
Google search engine would save a fair bit of energy due to the
popularity of the search engine. Since then there has been skepticism
about the significance of the energy savings that can be achieved and
the cost in terms of readability of black web pages.
We believe that there is value in the concept because even if the energy
savings are small, they all add up. Secondly we feel that seeing Blackle
every time we load our web browser reminds us that we need to keep
taking small steps to save energy.
How can you help?
We encourage you to set Blackle as your home page. This way every time
you load your Internet browser you will save a little bit of energy.
Remember every bit counts! You will also be reminded about the need to
save energy each time you see the Blackle page load.
Help us spread the word about Blackle by telling your friends and family
to set it as their home page. If you have a blog then give us a mention.
Or put the following text in your email signature: "Blackle.com - Saving
energy one search at a time".
There are a lot of great web sites about saving energy and being more
environmentally friendly. They are full of great tips covering the
little things that we can all do to make a difference today. Try
