- - - - Electncity cannot be stored; therefore, it must be transported to
        consumption centres This transport involves several processes:
        
        Increasing the voltage to 220 000 V or 400 000 V to prevent signif«.ant energy loss, due to the Joule effect
        
        Transporting it by high voltage cable~ attached to towers
        
        Decreasing the voltage at the electncity substations to 3-30 kV
        
        Distnbution to homes, offices, industnes and public faolities Dunng
        this srage, the voltage is reduced to 230-400 V.
- - - - These power plants use the kinetic energy uf the wind to move
        the blades of a rotor at the top of a tower,
    - - Photo-thermal power plant
        
        In this type of power plant, the heat generated by solarradiation produces steam
      - Photovoltaic power plant
        
        In these power plants, solar radiation is transformed directly into
        electncity by panels of photovoltaic cells.
    - - These plants use the heat found at deep levels in the earth. This heat
        may reach the surface in the form of steam, gases or hot water.
    - - Biomass
        
        Fo restry and agricultural waste
        
        Specific crops, such as sunflowers and cougar beet.
        
        kyraste from agri-food industries.
    - - The mechanical energy from the tides.
      - T he mechanical energy from the waves.
      - The energy from the ocean's thermal gradient.
- - - - Efficiency
      - Energy diversification
      - Energy savings.
