According to Darren Yates, the Blackle black Google background 
increases power use on small LCD monitors and only slightly decreases 
it for large monitors  <http://techlogg.com/content/view/360/31/>.

I tested it on a small DELL monitor and could find no deference, but 
my power meter only measures down to 1 Watt. Darren makes the point 
there are much better ways to save power than with Blackle.

My large Dell monitor uses 51 W with an image and 7 W in standby 
mode. I discovered that if I unplug the keyboard and mouse from the 
USB hub built into the monitor, the standby power drops to less than 1 Watt.

ps: Will be talking at Green IT in Sydney on 6 December and hope to 
use a "carbon neutral" computer for my presentation slides 

pps: Do not try measuring power use of a computer with a multimeter
