Facebook has published its 2011 corporate power consumption and carbon footprint.
The Guardian UK compared Google to Facebook.
Greenpeace gave their approval to the disclosure.
Greenpeace welcomed the move's transparency and hailed it as an important benchmark. Gary Cook, Greenpeace International's senior IT analyst, said: "Facebook has committed to being fully renewably powered, and today's detailed disclosure and announcement of a clean energy target shows that the company means business and wants the world to follow its progress."
If you plan on having a green data center and not being a Greenpeace target you should follow Google and Facebook with an annual disclosure of your power consumption and carbon footprint.
