- - - - conventional thermal power plants
        
        they produce air pollution, increase the greenhouse effect, sometimes also acid rain and when they release the water of the cooling system is still warm so that affects to plants and animals
  - - - waste treatment
        
        in thermal power plants we can take a lot of measures to reduce the pollution
        
        the nuclear power plants leave the nuclear waste in underground places or in ocean trenches
- - - - wind farms are a clean form of producing energy, but, they can only be placed in very windy places.
  - - - In this power plant the heat from of the solar panels produces the steam to move the rotor in the generator.
    - - they use solar panels to take electricity from the solar insolation
    - - This energy can be used directly for hot water and heating or it can be used indirectly for generate steam, wich produces energy
    - - We take all the organic compounds from agricultural and forestry waste, specific crops such as sugar beet and waste from agri-food.
        
        This biomass is subjected to some chemical and physical process to produce charcoal, alcohol or biogas.
    - - This power plants use the mechanical energy from the waves and the tides and also the ocean thermal gradient.
- - - - by origin
      - by use in each country
      - By availability in nature
        and capacity for regeneration
      - by enviromental impact
- - - - how it works?
        
        Electrical power plants use an external source of energy to produce
        electricity. To do this, they rely on a turbine-alternator system.
        
        turbine
        
        converts mechanical energy into the rotating movement
        of a shaft.
        
        alternator
        
        it has a fixed part, called a stator, and a moving part called a rotor, connected to the turbine shaft.
- - - - Increasing the voltage to 220 000 V or 400 000 V to prevent significant energy loss, due to the Joule effect.
        
        Transporting it by high voltage cables attached to towers
        
        Decreasing the voltage at the electricity substations to 3-30 kV
        
        Distribution to homes, offices, industries and public facilities during this process, the voltage is reduce to 230-400v
