This from Jesse Fahnestock and his colleagues at the World Economic Forum:

Blackle is Google - but a black screen version.

A few months ago, Mark Ontkush wrote a post on his blog EcoIron titled
"Black Google Would Save 750 Megawatt-hours a Year ". The post lays out
the following train of thought. "An all white web page uses about 74 watts
to display, while an all black page uses only 59 watts." Google, which has
a white background and gets about "200 million queries a day "could reduce
global energy use by 750 Megawatt-hours a year by simply changing the
colour of its homepage to black.

In response to this post a black version of Google emerged called
Blackle.com. According to Blackle's homepage at publication time, 4,408.917
Watt hours have been saved by it.

Nice ideas. But how does the search measure up? Very well indeed. Use ‘web search' selection the Blackle screen to get same results from Google.

Give it a whirl yourself and start saving energy one search at a time. So
here's your site: http://www.blackle.com

Consider using this as your home page or default search engine. Consider
also passing this post on to people you know to spread the word.

if changing the background color of a webpageb to black from white saves so much energy why isn't GreenBase background black?
Fair enough question...um...
I've seen a few pages around which claim to help the environment in many ways, the main being - using a black screen energy consumption is reduced and therefore your "foot print" is reduced.

Personally I feel the savings are minimal and we need to take an additional more proactive approach. using http://www.regrowgle.com as a search portal does this. Any profits generated through searches on this site are actually reinvested into "green" projects such as forest regeneration. So in basic terms you are making positive changes to our world as you search. And the best this is - it costs you as a user - NOTHING!!

If for nothing else, at least give it a try and get your friends to have a go as well. There's nothing to loose, and a whole lot to gain.
