Facebook vows to run on 100 percent renewable energy by 2020

Facebook announced today that it’s reducing its greenhouse gas emissions by 75 percent and will make its operations run on 100 percent renewable energy by the end of 2020. These efforts are part of its pledge to combat climate change.

The company has signed contracts for more than 3 gigawatts of new solar and wind energy since it began such efforts in 2013, it writes in a blog post. These wind and solar projects are built on the same grid as Facebook data centers, including centers in Oregon, Virginia, New Mexico, and Sweden.

Facebook says that it has met its 2015 goal to support 50 percent of its facilities with renewable energy by 2018 early: last year, it reached 51 percent renewable energy.

Like Facebook, many tech companies are attempting to go green. In June, Samsung promised to make its operations in the US, Europe, and China run on 100 percent renewable energy by 2020. And Apple and Google have both purchased enough renewable energy, such as wind or solar energy, to offset their global energy consumption since April.
