Information and energy at John Quiggin

Information vs Energy: "According to the US Internet Industry Association, the volume of information transmitted over the Internet backbone rose from 1.5 million GB (petabytes) in 1995 to 700 petabytes in 2006, or roughly a factor of 500 in 10 years. In comments, Ikonoklast reports a five-fold increase in global energy use over 50 years. Over the same period, Brad Delong estimates a tenfold increase in global output. That is, the rate of growth of information greatly exceeds (and leads) the rate of economic growth, while energy use has declined relative to output. This is unsurprising, given that no fundamentally new energy technology (except for the so-far unsuccessful nuclear power industry) has emerged in this time, while information technology has been repeatedly revolutionised."
