Google’s mission is to organize the world’s information and make it universally accessible and useful. The company works hard to minimize the environmental impact of its services and has been a carbon neutral company since 2007. Google builds some of the world’s most energy efficient data centers; its facilities consume 50 percent less energy than a typical data center. Google also procures large volumes of renewable power. As of December 2016, the company has signed 20 long-term agreements totaling 2.6 gigawatts (GW) of wind and solar energy around the world, which is enough energy to power approximately 900,000 U.S. households. For any emissions Google cannot eliminate directly, it purchases high quality carbon offsets -- which brings its total carbon footprint to zero. Google also has committed to invest $2.5 billion in solar and wind projects, adding clean power to the grid. In combination with our investment partners, these investments have helped enable over 3.7 GW in total capacity, producing far more electricity than Google uses. To put this in context, this electricity is greater than that consumed by 1,000,000 U.S households.
