Ecosia , FORESTLE , Ecocho and Znout . These are the three currently known "green" search engine on the net. What is behind this new idea of what you do with it, and why you should do it, I will explain to you briefly.
Who ever

the green search engine tuen almost exactly the same. Here, too, ads will appear next to search results. The difference is the use of the recovered money. Instead of themselves to do business in the bag here is the money that is earned with the advertising, donated a green purpose. Some are reduced to single lichen offset the CO2 emissions of their servers, others go further and plant trees and save the rain forest with the money. The user come to no cost.
Znout
Znout stands for " Z ero n egative put out" and is currently the only green search engine that works with Google together. It is also something like the minimum program, in terms of green search engines. Google works as a market leader in terms of what the search network is not combined with non-profit organizations, because you could lose customers and reduce its own profit .
why limit ourselves to Znout on the pure CO2 emissions from the server. Znout has appointed a partner (http://www.co2stats.com/) determine the emissions of carbon dioxide that cause the Znout sites and then buys an equivalent amount certificates for renewable e energies in order to discharge balance.
Znout then, is the search engine of choice for those who absolutely must have exactly the search results from Google, but at least do not emit C02 on their search queries.

FORESTLE
Forestle setzt nach anfänglichen Querelen auf Zusamennarbeit mit Yahoo , anstelle von Google, kommt aber aus dem gleichen Haus. Das Prinzip ist ebenfalls das gleiche. Über Unterstützung der " Adopt an Acre " Stiftung (http://tinyurl.com/adoptacre) werden nach Angabe pro Suche ca. 0,1 m² Regenwald gerettet. Außerdem kommt hier auch die gleiche Taktik von Znout zum Einsatz. Das heißt, zu den 0,1 m² gerettetem Regenwald kommt auch hinzu, dass Forestle - genau wie Znout - eine CO2-Neutrale Suchmaschine ist. Die Suchergebnisse sind leider nicht mit denen von Znout/Google identisch, jedoch kann sich über the quality of the two are still debated.

Ecocho
This search engine is the only one of the four not out of the house but from Kroll Sydney. This makes itself felt in the other Anstaz. Instead of saving the rain forest are in Ecocho requests per 1000 new trees planted 1-2 which will be probably more than 100 years

Ecosia is a few days ago as "further development" touted by Forestle. Ecosia also comes from the same hands as Znout or Forestle. Through new contracts with Bing (the search engine by Microsoft) and Yahoo and the new cooperation with the WWF are now questioned by some indication Rgenwald 2 m² per search under protection (at least 20 times more than Forestle). Also Ecosia use green power for its servers. Moreover, from the ground up Ecosia professional, fast and international set, so probably the most promising Green search engine of them all.

What do these search engines is the idea that technology, logistics and moral superiority. What they do not have is money to place advertisements for themselves or otherwise make attention. It's up to us, the users, to disseminate these sites. there for every taste matching green search engine, to speak out does not work. Therefore, my plea to you: Verabschieded you from your old search engine and switches to the green alternative! brings And further the news. Link to the page in forums, on or on blogs and talk to your Friends about it. The more people look green, the better.
is any questions as always: comment to post, message on Twitter or YouTube. I reply as soon as possible.
tl, dr:
Tolle sustainable alternatives to Google! Find, get the same results as with Google, Yahoo or Google and the way the rain forest saves by itself! And all the costs you exactly nothing. So please use and spread the word.
