Will Black background save power.....?

Hi,

http://www.blackle.com/ is a customized google search engine with black background to save energy.

The concept behind is CRT monitors uses less energy in displaying black pixels than displaying white pixels. So using black background for web pages, ultimately reduces power consumption by CRT monitors.

The energy saved by using black google is around 750 Megawatts hours a year as per blackle.com.
