Electricity is even more well timed than airplanes.
You can put an airplane in a holding pattern for a short while. If we don't plant the electricity and we don't have it when it's 103 degrees, you'd think it's the end of the word. We're very used to it, very dependent on it. The rolling and the brownouts are the rationing. We have a wonderful electric supply system.
