Energy Storage Media is a method or a tool to keep some form of energy that can be taken at any given time for various purposes. A device used to store energy is sometimes called an accumulator. All forms of energy which belong to the potential energy (eg: chemical energy, electrical energy, and so forth) or thermal energy can be stored. Rotary mechanical clock store potential energy in a mechanical voltage.
Batteries store chemical energy that can be converted directly into electrical energy by connecting the two poles with electrical equipment. Energy-saving hydroelectric dams with reservoir water as gravitational potential energy. Food is also an energy storage media, namely, chemical energy, even the ice can be said as a means of thermal energy storage and will be used when the need for cold temperature is required.
