Why isn’t there enough energy?

Most of us have lived our lives thinking that electricity is unlimited. Sure, there are power outages from time to time, but once they fix the problem, we’ve always had enough power to go around. But in reality, electricity is a limited resource. It has to be produced just like any other product. So when your A/C kicks on, a powerplant has to make your electricity and deliver it to you, almost instantaneously. Unfortunately, we can’t stockpile electricity to use whenever we need it. And this summer, there is a chance that there may not be enough electricity to go around.
