What a great quote from this article on energy usage:

"THE KEY TO MODERN LIFE IS STRATEGIC IGNORANCE. There are so many things we don't know about our lives and that, frankly, we don't want to know. We don't know much about the basic things that sustain us. We are clueless "end users" in elaborate industrial supply lines. Energy comes from distant power plants and oil refineries and pipelines and electrical grids, but we don't think about them when we flick on a light or turn the key in the ignition. We live in a world we didn't make, by rules and customs and laws we didn't invent, using tools and technologies we don't understand."
