You may not think about it often, but the Internet uses a colossal amount of electricity. This, in turn, means that the Internet’s carbon footprint has grown to the point where it may have eclipsed global air travel , and this makes the Internet the largest coal-fired machine on Earth. These include data transfer (i.e.
