Blackle is a website powered by Google Custom Search, which aims to save energy by displaying a black background and using grayish-white font color for search results.

You might now be asking? How does this Blackle help in Energy Saving ?

The concept behind Blackle is that computer monitors can be made to consume less energy by displaying much darker colors. Blackle is based on a study which tested a variety of CRT and LCD monitors. There is dispute over whether there really are any energy saving effects.

This concept was first brought to the attention of Heap Media by a blog post, which estimated that Google could save 900.0 megawatt-hours a year by utilizing it for CRT screens. The homepage of Blackle provides a count of the number of megawatt-hours that have been saved by enabling this concept.
Examination

Darren Yates, a technology journalist who reviews computer hardware, tested 4 CRT monitors and 23 LCD monitors, and found that the CRT monitors did use more energy displaying a white screen, but less than the calculations made by the blog post that inspired 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. Blackle claims to have saved 1,678,533.079 megawatt hours
