What It Really Means When Google and Apple Say They Run on 100% Renewable Energy
The role of RECs, the concept of “additionality”, and their impact on the earth
Apple, Amazon, Google, Facebook, and Microsoft — five companies that arguably make up “big tech” — say they are either already powered by 100% renewable energy or are close to getting there.
Together, these companies own and operate more than a hundred data centers (each the size of multiple football fields), close to a thousand offices, and countless other buildings, making them some of the most power-hungry companies in the world.
