This week, Facebook announced that it plans to use 100% renewable energy by 2020.
In a blog post, the social network said it will reduce its greenhouse gas emissions by 75% and power the company's entire global operations by renewables by the end of 2020.
In 2015, Facebook set a goal of supporting 50% of its facilities with renewable energy by 2018 - a target it reached in 2017.

Facebook said: “In a record-breaking year of corporate renewable energy purchases, Facebook is on track to be one of the largest corporate purchasers of renewable energy.
“Since our first purchase of wind power in 2013, Facebook has signed contracts for over 3 gigawatts of new solar and wind energy, that includes over 2,500 megawatts in just the past 12 months.”
Greenpeace praised Facebook’s environmental effort in a report published in 2017, giving it an A-grade alongside Apple.
Greenpeace said: "Facebook was the first major internet company to commit to be 100% renewably powered and continues to play a leadership role within the sector.
"Showing strong transparency and a track record of its five latest data centers sighted in locations that allowed them to be renewably powered."
Other tech companies like Google and Apple have also committed to using 100% renewable energy, as well as companies like Walmart, Target and Starbucks.
