If the Internet was a country, its electricity use would rank sixth highest in the world. That huge power demand, and the potential to drive a renewable energy solution to its sourcing is the basis for Greenpeace’s report on tech companies that are moving toward one hundred percent renewable energy to power the Internet. For the report, Clicking Clean: How Internet Companies are Creating the Green internet, Greenpeace has evaluated 19 tech companies, including a review of over 300 data centers that make up their electricity supply chains. Five companies—Apple, Facebook, and Google, along with B2B companies Rackspace and Salesforce—have committed to a goal of powering their operations with one hundred percent renewable energy.
