Facebook is one of the world’s largest corporate purchasers of renewable energy, having signed deals for more than 5 gigawatts of “clean” power—3.5 gigawatts of which is expected to be online by the end of the year. (One gigawatt is enough to power 700,000 homes for a day, according to some estimates.)
The company uses all that energy to power the vast data centers that run its social media platforms, as well as to keep its various offices humming—though Facebook, along with other large technology firms, has been faulted by environmental groups for the sheer amount of energy its data centers consume.
