- - - - Electrical power plants use an external source of energy to produce electricity. To do this, they rely on a turbine-alternator system.
    - - Electricity cannot be stored; therefore, it must be transported to consumption centres This transport involves several processes:
        
        Transporting it by high voltage cables attached to towers.
        
        Decreasing the voltage at the electncity substations to 3-30 kV
        
        Increasing the voltage to 220 000 V or 400 000 V to prevent signiicant energy loss, due to the Joule effect.
        
        Distnbution to homes, offices, industries and public facilities During this srage, the voltage is reduced to 230-400 V.
- - - - The water used in the cooling system is returned to the environment while it' still warm, which affects both animal and plant life
      - They emit large amounts of CO2, which increases the greenhouse effect.
      - They emit sulphur dioxide and nitrogen oxide that cause acid rain,which is very harmful to theenvironment
      - They produce air pollution — suspended particles, CO, heavy
        metal molecules and so on.
