Facebook, Greenpeace in truce over data centers

Greenpeace and Facebook said Thursday that they will work together to encourage the use of renewable energy instead of coal. Last year, Facebook opened a data center in Prineville, Ore., using the area's cool nights and dry air to save energy while keeping its systems from overheating. It also received generous tax breaks for adding jobs to the economically struggling region.

But Greenpeace wasn't happy that Facebook picked a power company that generates most of its electricity from coal to power the data center. It started a campaign to get the social network operator to use renewable energy. It attracted some 700,000 supporters on Facebook. Greenpeace said it was ending the campaign and declared victory on its "Unfriend Coal" Facebook page, which was still up Thursday morning.

The page has more than 180,000 followers.

Facebook says it will work with the group to promote clean, renewable energy and encourage other technology companies to do the same. The company said it will now state a "preference for access to clean and renewable energy" when choosing where to build its data centers. But it stopped short of saying it will only build on such sites.

Clean energy has also been big issue for Facebook's Silicon Valley Google Inc. The online search leader has been trying to prove that its business model is environmentally friendly and recently revealed exactly how much electricity it uses (2.3 kilowatt-hours of electricity last year, about the same as what 207,000 U.S. homes would use in a year). It has also invested nearly $1 billion in renewable energy projects such as wind farms and solar projects.
