Blackle
Blackle is a website powered by Google Custom Search and created by Heap Media, which aims to save energy by displaying a black background and using grayish-white font color for search results.〔http://www.blackle.com/about/〕 Blackle claims having saved over 4 MWh of electrical energy up to November 2013,〔http://www.blackle.com/〕 a claim currently under dispute. For comparison, the average USA household consumes 11 MWh of electrical energy per year.〔(【引用サイトリンク】title=Residential Average Monthly Bill by Census Division, and State )〕
== Concept ==
The concept behind Blackle is that computer monitors can be made to use 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, especially for users of LCD screens, where there is a constant backlight.〔(Monitor Energy Information ) for Energy Star, United States Department of Energy〕
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.〔(Black Google Would Save 750 Megawatt-hours a Year ), by ecoIron. The blog post by that inspired Blackle.〕 The homepage of Blackle provides a count of the number of watt hours claimed to have been saved by enabling this concept.
