Let’s start with a big question and then go from there. Today’s big question is this: How green is the internet? To be fair, it’s a question that’s already been asked - not least at a Google sponsored summit in 2013 that included Bill Gates as a keynote speaker. The answer is, perhaps inevitably, not quite as bright, shiny and cheerfully upbeat as all those shiny screensavers would have you believe. Lest we forget, the internet runs on electricity.
