So Ive been having this discussion with a group of friends and some of them disagree with me. Can you store electricity? My answer is no. You cannot store electricity. Electricity is the movement of electrons. When these electrons are sitting in place they are not performing work. In the case of chemical energy (i.e. batteries) no work is being performed. Therefore, you are not storing electricity but you are storing potential energy or potential work. In the case of a capacitor these electrons build up a charge and you are storing their charge but electricity is not being stored. I know this is a stupid question but am I right? Please shed some light on this.
