Google on 100% renewable energy in 2017

I’m thrilled to announce that in 2017 Google will reach 100% renewable energy for our global operations — including both our data centers and offices. […]
Today, we are the world’s largest corporate buyer of renewable power, with commitments reaching 2.6 gigawatts (2,600 megawatts) of wind and solar energy. […]
To reach this goal we’ll be directly buying enough wind and solar electricity annually to account for every unit of electricity our operations consume, globally.
