The capacitor stores the energy until it gets discharged after connecting it with some other electronic devices that demand an electric charge. The gravitational potential energy is stored in the object until it reaches the ground, and chemical potential energy is stored in our body until it is utilized to do the work.

Thermal energy is stored in the object till it is radiated out from the object. The elastic potential energy is held within the object only when it is stretched or compressed and lost when it is released.

Methods for energy storage

Here is a list of methods to store the energy:-

Rechargeable Batteries

It stores the electric power and can be used anytime as required.

Storing Fossil Fuel

Fossil fuel is a form of chemical energy that stores within it.


Compression of the matter can build the potential energy within it.

Chemical Batteries

This works on the principle of redox reaction and produces electrical energy by converting the chemical energy which is formed by breaking and formation of new chemical bonds.


In order to store the kinetic energy and also to prevent any energy loss, the wheel is fixed on a frictionless by using electrical energy.


The radiant energy can be captured and stored this energy by converting it into some other forms of energy. For example, solar energy is stored as electrical energy by using solar panels and generators, solar heaters, solar cookers, solar cells, etc.


It is a method to store electricity by converting magnetic energy. The magnetic field is produced as the current flows through a coil which is cooled below the critical temperature.

Establishing Turbines on Dams

The turbines produce the mechanical energy by converting the kinetic and potential energy of water flowing from the dams which can be further converted and stored as electrical energy.


On elongating the elastic material the elastic potential energy will be built up in the material.

The energy can be stored in the interior of the Earth in the form of nuclear energy due to high temperatures and pressure.

The electrical energy is stored in the clouds, the gravitational energy between the heavenly bodies, mechanical energy in moving automobiles, and magnetic energy in magnetic material, elastic potential energy in the elastic material.

Can energy be stored in a magnetic field?

Magnetic energy is a renewable and free source of energy and can also be produced by passing the magnetic flux lines through the material.

The magnetic energy exists only in the magnetic field region and is given by

. The energy of the magnetic field is high if the density of flux is more.

This energy is utilized to align the dipoles so that the material can conduct more magnetic field and increases its strength.

How is energy stored in a magnetic field?

The energy stored in the magnetic field depends upon the flux lines penetrating a region, the density, and the alignment of the magnetic dipoles.

The magnetic field energy is stored in the field based on the density of the flux running in the field by the electric current. Even the electric motor starts rotating when the electric current passes through it producing the magnetic field and energy.
