According to http://www.digitslcleanupday.org, 70 million servers store data; each produces 1–2 tons of CO2. Our data storage uses 3 times more energy than all the solar panels the world can produce! An average email emits 4g of CO2, the same as a light bulb on for 6 minutes! Remove unused apps, delete duplicate and useless computer files, and archive or delete old emails.
