ENERGY IMG_1031, Biomass - Coggle Diagram

- - - - A car has a mechanical store of energy
    - - A hot metal or a hot drink has an internal (thermal) store of energy
    - - A stretched rubber band or a compressed spring has an elastic (strain) store of energy
    - - A loud speaker has a sound store of energy
    - - A light post or a light bulb has a light store of energy
  - - - A stretched rubber band or a compressed spring has an elastic (strain) of energy
    - - The food that we eat, fossil fuels and batteries have a chemical store of energy
    - - Formula: mgh
      - An object such as a ball raised to a height above the ground has a gravitational potential store of energy
- - - - Comes from the sun. The energy in the nucleur store of the Sun is transferred by infrared electromagnetic waves to the thermal store oh a solar panel for heating water.
        
        Advantages
        
        Less polluting
        
        Renewable
        
        Disadvantages
        
        Not always available
        
        Uses a lot of space
    - - a renewable energy source that generates electricity by using the natural flow or fall of moving water
      - Disadvantages
        
        Expensive to build
      - Advantages
        
        Clean and Renewable
    - - Wing energy captures the motion of air currents using tall turbines to rotate generator blades, providing a clean, endless power source with zero atmospheric emissions
      - Advantages:
        
        Clean source of renewable kinetic energy with zero emissions during operation
      - Disadvantages:
        
        Only works when it is windy
    - - Gravitational pull from the moon and sun creates ocean tides, forcing trapped water through underwater turbines to generate electrical power
      - Advantages:
        
        Easy to predict because ocean tides are constant
      - Disadvantages:
        
        Expensive to build
    - - Volcanic regions push large amounts of hot molten rocks near the Earth's surface. They are called geothermal hotspots. Water that makes it there is heater and subjected to great pressure. The water has a large thermal store of energy. It is forced to the surface as boiling water and steam to drive turbines to generate electrical power.
        
        Advantages
        
        Clean source of natural thermal energy
        
        Renewable
        
        Disadvantages
        
        Causes environmental pollution by the releasr of poisonous gases.
        
        Not wideley available
  - - - When a fuel is burnt in air, heating transfers energy from the chemical store of the fuel to the thermal stored of the surroundings
        
        Advantages
        
        Widely available
        
        Cheaper in cost of production
        
        Disadvantages
        
        Pollution from the gas
        
        Non-renewable
    - - Energy from the nucleur store in nuclear feuls, such as uranium, can be transferred to large thermal sources to heat up water into steam.
        
        Advantages:
        
        Higher reliability in supplying uninterrupted power
        
        Reduces green house gas emissions that cause global warming
        
        Disadvantages
        
        Risks of accidents and pollution from the improper disposal of radioactive wastes
        
        Non-renewable energy resource as the amount of nuclear fuel is limited
