If you want to “go green” while conducting your searches, then a new search engine is right up your alley. Echocho promises to grow up to 2 trees for every 1000 searches. The search engine allows users to choose whether they wish to conduct searches on Yahoo or Google.
As of this post, Ecocho had planted 2,873 trees which they say offsets 1,436,710 kilos of C2. The trees are purchased using 70 percent of advertising revenue. Echocho also has a toolbar which is available to download for Firefox or IE6 and IE7.
The design of Echocho features a white background, which may prove controversial for some eco-evangelists. Last year, Blackle launched as a Google custom search engine with a black design, which they said would reduce the amount of watts used during searches. As of this post, Blackle claims to have saved the earth 567,579.120 Watt hours.
The “big” search engines are no stranger to green initiatives. Last summer, Yahoo was trying to find the “Greenest City in America” while Google hosted a “Summer of Green” site that listed environmentally-friendly hotels and vacation destinations.
