Energy stores

Jonny Nelson introduces an animated explanation of energy stores

There are a number of different ways in which energy can be stored. Energy can be transferred from one to another by working and heating.

A diagram shows seven types of energy stores with a picture example of each.

Some examples of everyday energy stores are:

  • gravitational potential ‐ the energy stored in water at the top of a mountain is used for hydroelectric power
  • kinetic ‐ the energy stored in a flywheel is used as an alternative to traditional batteries in a hybrid car
  • thermal ‐ the energy stored in the concrete blocks of a night storage heater is released during the day
  • nuclear ‐ the energy stored in the nucleus of an atom of uranium is released when the atom undergoes nuclear fission
  • chemical ‐ the energy stored in the chemicals of a battery or in the fuel at a power station is transferred as an electric current to do work on domestic appliances
