The best way to understand electricity is to start by giving it its proper name: electrical energy. If you want to run anything electrical, from a toaster or a toothbrush to an MP3 player or a television, you need to feed it a steady supply of electrical energy. Where are you going to get that from? There's a basic law of physics called the conservation of energy that explains how you can get energy—and how you can't. According to this law, there's a fixed amount of energy in the universe and some good news and some bad news about what we can do with it. The bad news is that we can't create more energy than we have already; the good news is that we can't destroy any energy either. All we can ever do with energy is convert it from one form into another.
