Black Is The Interwebs New Green
Blackle.com
Environmentally-friendly search engine. The Black background is supposed to help reduce energy consumption. 2 years ago a blog (click link to read) was posted claiming that a Black Google could save 750 megawatt-hours per year. The exact numbers of energy that could be saved are unknown, but as the creators of Blackle state:

"We believe that there is value in the concept because even if the energy savings are small, they all add up. Secondly we feel that seeing Blackle every time we load our web browser reminds us that we need to keep taking small steps to save energy."

Donate Pennies By Searching
GoodSearch.com
GoodSearch works much the same way advertisements on websites work, by the amount traffic they receive. GoodSearch allows you to save the name of a charity, and then make interweb searches in the same way you would use Yahoo! or Google. For each search made $0.01 is donated to the charity that you chose. Search engines generate income through advertizements and sponsored search results. Since those advetisers are paying for you to see their ads, GoodSearch passes on a small fraction of the generated income to the charity of your choice, with an extensive list of charities and schools that you can GoodSearch for. If you belong to, or work with a charity/school that is not listed, you can simply have GoodSearch add it to the list. Large or small organizations can benefit from this simply by encouraging it's members or faculty to use GoodSearch for their interweb searching needs.

A small organization with 100 people, making 2 searches a day each would generate and estimated $730 each year.

An organization I work with uses GoodSearch and it's an excellent source of extra money especially since it's funds that otherwise would not have been raised, and it involved absolutely no work, or investments. All it takes is a few people to keep good causes in mind while surfing the web.
