Kinetic pumped storage systems

  • Kinetic pumped storage systems use the energy from motion to generate power.
  • Kinetic pumped storage systems have two reservoirs of water and a hydroelectric dam.

  • When the demand for electricity is high, the dam is opened and water from the top reservoir passes through turbines to the lower reservoir, generating electricity.
  • When the demand for additional electricity is less, the dam is closed and the water is pumped back up to the top reservoir and stored for future use.

Alkaline batteries

  • Alkaline batteries come in different sizes and voltages.
  • Alkaline batteries can be found in electronic devices such as torches, clocks and children’s toys.
  • Alkaline batteries are mainly single-use and can be recycled through collection schemes when used.
  • Alkaline batteries are now more commonly used than previous acid-based batteries as they keep their charge for longer.
  • Alkaline batteries have a long shelf life so can be stored for years unused with minimal loss of energy.

Rechargeable batteries

  • Rechargeable batteries can be reused.
  • Many can be removed from devices enabling them to be charged when not in use.
  • Used to power small electronic devices and large vehicles.
  • Although the initial cost is higher some can be recharged around 1,000 times, saving the consumer money.
  • Positive environmental impact as less waste goes to landfill and fewer materials and processes are used in the manufacture of more batteries.
