Facebook has signed a long term renewable energy agreement with Vattenfall to power its data centres.

It is buying 100% of the electricity from three Norwegian wind projects for its data centres in Denmark and Sweden.

Vince Van Son, Facebook’s Commercial Director for Energy and Infrastructure said: “These projects will add wind energy to the Nordic grid, providing a 100% renewable solution to our data centre campuses in Odense, Denmark and Lulea, Sweden.

“It will also provide a renewable solution for the electricity consumed at the energy centre in Odense, enabling the production of renewable heating for the community from the heat recovered at our data centre.”

The organisation has committed to have at least 50% renewable energy in its company-wide energy mix in 2018.
