Searching for a good purpose

In early 2010 there were reports that two search enquiries at Google consume as much energy as is used for heating up a cup of water. With the respective CO2 emission.

"We have found out that visiting a website causes an emission of about 20 mg of carbon dioxide per second", says US American physicist Alex Wissner-Gross who creates ecological balances of websites.

Parallel to the Climate Chance Conference in Copenhagen a second search engine went online with which almost two square metres of rain forest are saved with each search enquiry. According to their own statements, Ecosia works with climate-friendly green electricity. They say that the "green electricity" for the web servers are provided by an EnBW subsidiary.

How Does Ecosia Generate Income?

Yahoo and Bing not only help us to provide excellent search results; they also supply us with the sponsored links that we need to generate advertising revenue. Sponsored links are short, relevant text ads, which are placed by companies aiming to sell their products and services to users of the search engine. Companies pay for each click on their sponsored link and every click on these ads generates a few cents of revenue for the search engine.

About 2% of Ecosia searches lead to a click on a sponsored link. Doing a mixed calculation of normal clicks and clicks on sponsored links, Ecosia earns about 0.13 Euro cents per search. We donate at least 80% of this income to the WWF. Thanks to these donations, we can save about two square meters with every search.

How Does Ecosia Save The Rainforest?

Ecosia does not conduct the rainforest protection scheme itself; instead we donate to a rainforest protection program run by the WWF. The current WWF project is located in Juruena National Park in the Amazon region of Brazil. Click here to learn more about the current rainforest protection project.
