ENERGY - Coggle Diagram

- - - - COMBINED CYCLED POWER PLANTS:Electricty is generated as a result of two combined cycles.During the first cycle,a gas turbine is used that includes a compressor.Air is mixed with the gas and is burnt, which generates electricity in the turbine system.The combustion gases are transported to a boiler , where transfer energy to the water
  - - - Gravitity-driven hydraulic power plants:water used follows the course of a river and will not be reused
      - Pump-driven hydraulic power plants:water descends into a reservoir located at a lower
        height, then pumped to a higher reservoir to reuse it
- - - - Are facilities when primary or secundary energy can be transformed into electricity
    - - Electric power plants are usually located far away from the points where the energy is used ,for safety reasons space requirements or physical and geographical considerations
- - - - Photovoltaic power plants
      - Photo-thermal power plants
    - - Biomass consists of all organic compounds that are produced through
        produce sugar; its leafy plant is natural processes
        
        Forestry and agricultural waste
        
        Specific crops, such as sunflowers and cougar beet
        
        Waste from agri-food industries.
    - - Use the energy from the ocean and seas
        
        three types
        
        T he mechanical energy from the waves.
        
        The energy from the ocean's thermal gradient
        
        The mechanical energy from the tides.
- - - - As part of a technicaj proiect, it's mandatory to carry out an environmental impact assessment to find out what changes it would
        provoke in the environment
    - - Extraction of natural resources
        
        The exploitation of fossil fuels and nuclear power means the depletion
        of resources, which makes it necessary to find new ones
      - Fuel transport
        
        Oil is transported by means of oils pepelins and oil tankers.Oil pipelines can suffer accidents caused by nature or human error,
        which result in uncontrolled spills.
      - Electricity generation
        
        Large hydroelectric power plants
        
        Conventional thermal power plant
        
        They produce air pollution — suspended particles, CO, heavy
        metal molecules and so on.
        
        They emit large amounts of COa which increases the greenhouse
        effect
        
        They emit sulphur dioxide and nitrogen oxide that cause acid
        rain, which is very harmful to the environment
        
        The water used in the cooling system is returned to ihe environmem
        while it's sull warm, which affects both animal and plant life
        
        Nuclear thermal power plant
      - Final energy use
        
        Thc fuels we use in vehicles and heating systems emit gases and
        part.les similar to those generated by convenuonal thermal power plants
    - - To reduce the waste generated by thermal power plants, as well as
      - Waste from nuclear plants is stored in drums with thick sides to not let the nuclear radiation escape
    - - Below is a summary of different possible solutions to alleviate some of
        the environmental problems descnbed
        
        Energy diversification
        
        Efficiency
        
        Energy savings
