Energy - Coggle Diagram

- - - - Electricity cannot be stored; therefore, it must be transported to consumption centres. This transport involves several processes:
        
        Transporting it by high voltage cables attached to towers
        
        Decreasing the voltage at the electricity substations to 3-30 kV
        
        Increasing the voltage to 220 000 V or 400 000 V to prevent the significant energy lose ,due to the Joule effect.
        
        distribution to homes, offices, industries and public facilities. During this stage, the voltage is reduced to 230-400 V.
  - - - 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 shaft moves, alternating electrical current is produced on each of the stator's coils.
- - - - At this type of power plant, water is heated in a boiler by the heat generated from the combustion of a fossil fuel, usually natural gas or coal
    - - This type of power plant uses the potential energy provided by the height of the stored water in a dam, converting it into kinetic energy. This energy moves the blades of the turbine. Depending on the destination of the water, hydraulic power plants are divided into two types, gravity or pump.
    - - This type of plant includes a nuclear fission reactor that produces the pressurised steam needed to move the turbine rotor.
- - - - 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. Geothermal energy may be used directly — for hot water and heating,industrial use and so on — and indirectly — the heat generates steam, which produces electricity.
    - - Biomass consists of all organic compounds that are produced through natural processes. They may come from the following sources: Forestry and agricultural waste. specific crops, such as sunflowers and sugar beet. waste from agri-food industries. Biomass Is sublected to different physical and chemical processes in order to produce fuel such as charcoal, alcohol or biogas,
    - - these plants use the energy from the sun There are two main types of instalations: photo-thermal and photovoltaic power plants.
    - - These power plants use the kinetic energy of the wind to move the blades of a rotor at the top of a tower, this is referred to as the wind turbine. Wind farms are a clean form of generating electricity However, they can only be instafled in plates with appropiated wind conditions
    - - These power plants use the energy from the seas and the oceans. 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. These power plants are still in the experimental phase and their level of production Is still very low.
