It frustrates me when energy consumption is used as a proxy for growth. That was probably true during industrial periods when manufacturing was the key economic producer, but isn't education and time more important now? Of course energy is still important to that, but to take a simple example - I can build a web store much more quickly now than I could 15 years ago thanks to the advent of frameworks, and indeed I don't need to build one myself as I can use an already developed one. My time can now be spent developing novel things.
