It's human nature to resist change. People only change when it's forced onto them. And so, the majority will keep going as they have until there is a panic, causing the herd to change it's paradigm. What's cool now might be stoned then. This 'panic' has to come before the change to new/different energy sources, or personal reduction of energy use. I'm already doing my part by staying in my chair as much as possible.
