Google plans to boost its purchase of renewable energy so that it buys the total value of its energy consumption from green sources, although it will continue to use some fossil fuels.
The shift does not mean Google will source 100% of its energy needs from renewable sources, because it will still have to rely on non-renewable power for some of its locations when a renewable source is unavailable.
However, it will purchase a unit of renewable energy for every unit of fossil fuel electricity its datacentres, offices, and other facilities consume worldwide, in order to offset this consumption.
Wind power will represent Google's primary source of renewable energy followed by solar power. Google noted how plummeting prices for certain renewable energy sources helped to prompt its decision, as prices during the past six years for wind and solar power fell 60% and 80%, respectively.
