The Information Technology Industry Council (ITI) said today that Facebook has joined the Digital Energy Solutions Campaign (DESC)  in an effort to develop energy efficient computing systems.

"Our ongoing philosophy has been to improve the efficiency of our infrastructure and we continue to invest tremendous resources to improve our own operations,” said Jonathan Heiliger, Vice President of Technical Operations at Facebook.

“By creating and sharing innovative technology solutions, we hope to help raise the visibility of the importance of environmental sustainability across all industries. Today, we’re proud to be joining with DESC to help make efficiency and environmental responsibility a priority for everyone."

Earlier this year, Facebook engineers launched a programming language, HipHop for PHP, which allowed their servers to do the same amount of work with half the number of servers. To spread the benefit, Facebook has open sourced the programming language so that other companies can get the same energy saving benefits.

To promote its sustainability efforts, Facebook has also launched a Facebook/green Page as a resource for individuals and organizations. Facebook will be working with environmental organizations to administer the Page.
