With the advent of social media like Facebook, Twitter, and Instagram, humans have increased their production of digital content. Even simple online interactions generate carbon emissions; a Google search has been estimated to generate 0.2 grams of CO2. To keep pace with growing online media, there is an increasing dependence upon data centers, which now account for 2% of the US’s electricity consumption.
