Who’s the dirtiest of web services out there? Twitter!

Trust Greenpeace to come up with the dirt on companies that are less than green, at least in their eyes anyway.

On Thursday at GigaOM’s Green:Net 2011 event the Greenpeace organization released a new report that examined some of the biggest web oriented companies and their use of clean power used to power their web operations.

Granted none of the companies in the provided chart did very well but as you can see, Twitter flunked right across the board. Even more of a concern in the eyes of Greenpeace however is that Twitter is expected to add to the problem of dirty power usage as it grows.

Tsk Tsk little bluebird of mundane 140 character chatter.
