Information processing requires power and physical structures to maintain the networks and store thousands of terabytes of information generated every second worldwide (that’s a number of bytes with 17 zeros). Data centers, massive information storage processors, use a lot of power and also require power to cool them down, due to overheating. Where do you think this energy comes from?
As you recycle your physical waste, you can also do so with your e-waste, which can help to reduce your digital footprint. Some sources say that by deleting 10 emails can save a tree measured by CO2 impact. It is, however, difficult to grasp how these estimates were made. Nevertheless, we know for sure that deleting old emails is beneficial for the environment, as less data is being managed by data centers, and hence, less energy is used by processors.
