I was introduced to Blackle today. I had never heard of it before (which made me feel a little bit clueless), but it’s a search engine that apparently saves energy because the screen is almost entirely black. And black pixel screens need less energy to load than white pixel screens. EcoIron even posted a blog last year on how this ‘Black Google’ would save 750 megawatt-hours a year.
Although it is powered by Google Custom Search, it is not owned by Google. So it doesn’t have a lot of Google’s features – like the ‘in cache’ or ’similar pages’ options. Also, a random Blackle search doesn’t find as much links as a Google search normally would. Still, I think it’s a good effort to making the world a little more environmentally conscious and wasting a little less. So I guess that Blackle is actually really Green. 
For those interested, there’s also a Wikipedia entry on Blackle and a Dutch Blackle version.

Same thoughts. I made an entry on my website too. Will there be a Google Maps in black? Only new York, Amsterdam, Utrecht and Stanford by night…
Why is the Dutch blackle so ugly compared to the US blackle?
Google did it
The problem with Blackle and heap media is that they are quietly making a packet off everyones goodwill via their adsense earnings.
These guys at Givle.com offer the same black search but the difference is all adsense funds go to charity.
Now that’s a real difference.

I think it would be great if you reviewed Givle, they are really onto something here.
