Ecocho

Price: Free

How it Saves: Ecocho proclaims itself to be the world's first 'green search engine' because it aims to offset greenhouse gas emissions by sponsoring the growth of up to two trees for every 1,000 searches users make through the ecocho site, which uses Yahoo and Google search-engine technologies.

The company has an agreement with Yahoo and Google to receive a percentage of advertising revenue. That money is then used to purchase carbon offset credits through the New South Wales government Greenhouse Gas Abatement Scheme, said Ecocho founder Tim Macdonald.

The search engine could be a very good thing after a US physicist claimed that using Google to conduct two web searches produces the same amount of carbon emissions as boiling a kettle.
