Green products and information search engine

Green is big.  And Greener is a search engine to use to find all things green.  I have found the search engine runs really quickly, which perhaps comes from the fact that they are searching "over 9 million pages and 50 million links," and not aiming for the entire web like general search engines.  Even so, they do seem really fast...always a plus.  I have found that the search results are easy to navigate, ad-free, and relevant.  Here are the results for a search for wind power.  This is definitely a resource I will recommend to library staff and users.
