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.
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 750 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.
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 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. As of 30 January 2010, Blackle claims to have saved over 1,680 kilowatt hours.
