- - - - energy produced: 1MW to 10MW
  - - - the heat genereated by solar radiation produces steam that is used to move the rotor in the generator
    - - solar radiation is transformed directly into
        electncity by panels of photovoltaic cells.
  - - - steam, gases or hot water
  - - - Biomass Is sublected to different physical and chemical processes
        
        The steam that is
        generated moves the turbine.
  - - - . The
        concept is to use three types of energy from the sea.
        
        The mechanical energy from the tides.
        
        The mechanical energy from the waves
        
        The energy from the ocean's thermal gradient
- - - - it is mandatory to carry out an environmental impact assesment to find out what changes it would provoke in the environment.
        
        an environmental study must also asses both the economic and social consequences of the project in the area
        
        then they decide whether or no to go ahead with the plan.
  - - - extraction of natural resources
        
        timber
      - fuel transport
        
        oil slicks
      - electricity generation

        nuclear thermalm power plants
        
        nuclear accidents
      - final use
        
        fuel uses
        
        when we turn on an electrical appliance, we are consuming energy that has alredy caused an environmental damaged during its extraction, generation and transportation
  - - - use of filters
      - Use coal with a low sulphur content
      - mantain and incerase the large forested areas
  - - - efficency
        
        reduce the energy we consume
      - energy savings
        
        adoption of more environmentally habbits
      - energy diversification
        
        use of renewable energy sources
- - - - • The turbine converts mechanical energy into the rotating movement
        of a shaft
        
        An alternator has a fixed part, called a stator, and a moving part,
        called a rotor, connected to the turbine shaft
        
        As the rotor shah moves, alternating electrical current is produced on
        each of the stator's coils.
- - - - This type of power plant uses the potential energy provided by the
        height of the stored water in a dam, converting it mto kinetic energy.
        
        Gravity-driven hydraulic power plants
        
        Pump-dniven hydraulic power plants
- - - - industrial uses:
    - - by availability in nature and capacity for regeneration
        
        renewable
        
        non-renewable
      - by origin
        
        primary
        
        secondary
      - by use in each country
        
        convencional
        
        non-convencional
      - by envioronmental impact
