ENERGY - Coggle Diagram

- - - - the operating of factories and companies, construction and agriculture
    - - electrical appliances, heating systems, hot water systems, heat for cooking or transport
  - - - renewable
      - non-renewable
      - By origin
        
        By use in each country
        
        By environmental impact
        
        Clear or non-polluting
        
        Pollutants
        
        Conventional
        
        Non-conventional
        
        Primary
        
        Secondary
- - - - for two reasons
        
        it can be easilty transformed into other forms of energy
        
        It can be transported long distances inexpensively and with very little energy being lost
  - - - are facilities where primary or secondary energy
        is transformed into electricity,
    - - They 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
        
        has a fixed part, called a stator, and a moving part,
        called a rotor, connected to the turbine shaft
    - - Types
        
        Nuclear
        
        It includes a nuclear fission reactor that produces the
        pressurised steam needed to move the turbine rotor
        
        Fossil fuel thermal
        
        water is heated in a boiler by the heat
        generated from the combustion of a fossil fuel,
        
        The steam that's generated moves the turbine connected to the generator
        
        Combined cycle power plant
        
        Electricity is generated as a result of two combined cycles, one that uses air and gas and a conventional thermal cycle
        
        Air is mixed with the gas and is burnt.
        The combustion gases are transported
        to a boiler, where they transfer their energy to the water
        
        Hydroelectric
        
        It uses the potential energy provided by the
        height of the stored water in a dam, converting it into kinetic energy
        
        Depending on the destination of the water
    - - Types
        
        Wind and wind farms
        
        use the kinetic energy of the wind to move the blades of a rotor at the top of a tower,
        
        Solar
        
        Geothermal
        
        Biomass thermal
        
        Ocean

        It burns all organic compounds that are produced through natural processes. These are subjectec to physical and chemical processes to produce fuel that is the one that is burnt
        
        1 more item...
        
        use the heat found at deep levels in the earth
        
        use the energy from the sun
        
        Photo thermal
        
        Photovoltaic
      - Advantages: they contaminate much less that conventional, usse renewable sources and reduce the energy dependence of petroleum and natural gas
        
        Disadvantage: they generate
        much less energy
- - - - Fuel transport
        
        Electricity generation
        
        Final energy use
  - - - Use coal with a low sulphur content
        
        Maintain and increase the size of large forested areas
  - - - Energy savings
        
        Energy diversification
