ENERGY - Coggle Diagram

- - - - An alternator has a fixed part, called a stator, and a moving part,
        called a rotor, connected to the turbine shaft.
      - the turbine converts mechanical energy into the rotating movement of a shaft.
- - - - the operating of electrical appliances, heating systems, hot water systems, heat for cooking and for means of transport.
    - - the operating of factones and companies construction, agriculture and so on.
- - - - These power plants use the kinetic energy uf the wind to move
        the blades of a rotor at the top of a tower, this is referred to as the
        wind turbine.
    - - These plants use the energy from the sun. There are two main types of instaflations: photo-thermal and photovoltaic power plants.
        
        PHOTO-THERMAL POWER PLANT
        
        In this type of power plant, the heat generated by solar radiation produces steam that is used to move the rotor in the generator.
        
        PHOTOVOLTAIC POWER PLANT
        
        In these power plants, solar radiation is transformed directly into electricity by panels of photovoltaic cells.
    - - 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.
    - - Biomass consists of all organic compounds that are produced through natural processes They may come from the following sources
        
        Forestry and agricultural wast
        
        Specific crops, such as sunflowers and cougar beet.
        
        Waste from agri-food industries.
    - - 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.
- - - - As part of a technical proiect, it's mandatory to carry out an environmental impact assessment to find out what changes it would provoke in the enviroment.
    - - Energy consumption is preceded by a long process, consisting of several stages, each ol which has an environmental cost.
        
        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 oil pipelines and oil tankers.
        Oil pipehnes can suffer accidents caused by nature or human error, which result in uncontrolled spills.
        Oil tankers can have accidents at sea, with the nsk of oil spills. Some spills have caused oil slicks that have taken years to clean up and dissipate and have aftected the lives of many plant and animal species.
        
        ELECTRICITY GENERERATION
        
        Large hydroelectric power plants require water reservoirs covering large areas, which profoundly change the natural cycle of rivers, flood large land areas and destroy ecosystems, in addition to increasing the risk of accidents
        
        Conventional thermal power plants can cause numerous problems and environmental hazards.
        
        Nuclear thermal power plants are accompanied by the risk of
        nuclear accidents and the problem of nuclear waste, some of which remain dangerous for thousands of years
        
        FINAL ENERGY USE
        
        The fuels we use in vehicles and heating systems emit gases and
        particles similar to those generated by convenuonal thermal power plants.
        When we turn on an electric appliance, we' re consuming energy that has already caused several environmental problems during its extraction, generation and transportation.
    - - To reduce the waste generated by thermal power plants, as well as their effects, several measures can be taken.
        
        Use coal with a low sulphur content, to reduce acid rain.
        
        Maintain and increase the size of large forested areas, since they absorb carbon dioxide.
        
        Install special filters on the pipes at the power plant to capture
        some of the gas pollutants.
      - Waste from nuclear power plants is stored in drums with thick
        sides that do not let the nuclear radiation escape. These are then
        stored in ocean trenches and underground.
    - - efficiency
        
        energy efficiency policies increase efficiency of everyday appliances and devices.
        
        noticeably reduce the energy we consume.
      - energy diversification
        
        use of renewable energy sources
        is fundamental.
        
        objective is to produce a large
        part of our eiectricity through
        alternative power plants.
      - energy savings
        
        essential to reduce the consumption of all forms of energy-without seriously affecting quality of life.
        
        adoption of more environmentally friendly habits.
