+2 is a website created by Heap Media and it looks like Google and is powered by the Google Custom Search, but it has one large difference. (clever name, right?) has a black background instead of the white background of we all know. 

The eco-thinking behind is some studies claim that darker images on monitors consume less energy, so this is Heap Media’s way to “remind us all of the need to take small steps in our everyday lives to save energy”. ranks in the top 8,000 websites as far as daily traffic.  In other words, it receives hundreds of thousands visits a month.  If their theory is true, then that is a lot of energy conservation.

Darren Yates, a technology journalist who reviews computer hardware, tested four CRT monitors and twenty-three LCD monitors, and found that the CRT monitors did use more energy displaying a white screen, but less than the calculations made by Blackle.  The LCD monitors tested showed slightly less power use displaying a white screen in the majority of cases, although most of the larger (24-inch) monitors did use slightly less power displaying a black screen. As of the writing, Blackle claims to have saved over 1,702 kilowatt hours.  The jury is still out on real life numbers.

Try it for yourself, maybe you’ll like it.  You can follow on Twitter as well at: and/or go to their energy saving tips.  Sometimes I use, but the black background is harder to read and can be a strain on the eyes.  It does, however, make for an interesting option to a very popular product.

You can also Google in black on your phone at!! It saves battery power and reduces bandwidth usage so your phone bills are cheaper...

Hmmm, what an interesting concept for a website.  I don't know if you recall National Lights Out Day (is that what it's called?) last year, or maybe the year before, something about energy conservation.  But anyways, Google changed their background to black the way Blackle in honor of that.  They gave an explanation about why they didn't do that every day -- that it didn't actually make a difference.  I'll have to find an article about that.  Thanks for sharing this, Clay!  This is interesting stuff!

I do remember Google changing its colors for one day.  Right, there are various Lights Out Days around the world.  The big one is coming up soon.  Earth Hour is March 27th, where everyone is asked to turn off their lights during the same hour around the world.  Thanks for reminding me.
