Google announced this week that it currently holds contracts to purchase 3 gigawatts of output from renewable energy projects, which is by far the most renewable energy purchased by a corporate entity to date. The tech giant says these contracts have led to more than $3 billion in new capital investment around the world. They also allowed Google to officially achieve its 100 percent renewable energy target. In December 2016, the company revealed it was on track to purchase enough renewable energy to match all the electricity it would consume over the next year.
