Following the link to the article about Landauer's principle[0] and then to Koomey's law[1] takes you to a set of facts that have stuck with me for years. Firstly: > As of 2011, computers have a computing [energy] efficiency of about 0.00001%. which means that computers could theoretically be made 10 million times more energy efficient. Even more strikingly, though: > Assuming that the energy efficiency of computing will continue to double every 1.57 years, the Landauer bound will be reached in 2048. The possibility of seeing a 10 million times increase in energy efficiency in my lifetime is hard to imagine, as indeed is the possibility that the practical limit is reached before 2048.
