Facebook meet Greenpeace’s attack against the plans of the IT company for its new data center in Oregon.

Facebook announced that its newest TsoD will be truly a model for energy efficiency, despite all the accusations of eco-organization.

A few days ago Greenpeace launched a campaign against Facebook for exerting pressure to stop using electricity from coal-fired plants.

Concerns of environmental groups on Facebook and its new big data center in Prinvil, Oregon, are associated with that facility will be twice bigger than expected and will work with electricity mix, which disproportionately strong coal present at largest source of global warming.

Director of Facebook Policy Shnit Communications Barry responded by saying that the planned data center is selected with a focus on energy efficiency. Shnit noted that Facebook, like any other company does not control the fuel source for their electricity.

It is true that 58% of the region’s electricity is produced by coal, compared with 50% average for the country, said Shnit, but on the other hand TsoD new site was chosen because of its temperate climate that allows Facebook to use in efficient refrigerators and not the traditional electric air conditioners, ever hungry for power. They represent one of the major consumers of electricity.

By consolidating in one place instead of renting space in various locations, Facebook can design center for maximum efficiency.

Shnit said facility in Oregon will have a rating of energy efficiency of 1.15, well below industry averages. Google, which is considered a leader in this respect for rating last month was about 1.17.

Google, Facebook, Yahoo and other IT companies are investing billions of dollars building data centers to meet growing demand for Web services.

Given that energy is a cost to them, these Web companies have a major financial motivation to use as possible less electricity.

This and rising environmental concerns have led to projects that optimize cooling, which traditionally consumes about half the energy used in data centers.
