Energy Sources - Coggle Diagram

- - - - Pros
        
        Operation & Maintenance costs are very low
        
        Completely Silent
        
        Can install in residential settings
      - Cons
        
        Some toxic chemicals, like cadmium and arsenic, are used in the PV production process.
        
        Solar energy is somewhat more expensive to produce than conventional sources of energy due in part to the cost of manufacturing photovoltaic devices and in part to the conversion efficiencies of the equipment.
        
        Not always available, (Cloudy weather, night time)
        
        Low effiency
        
        Can be damaged easily
      - Sample Problem
      - Defined
    - - Cons
        
        Costly
        
        Weather Dependent
        
        Occupies a lot of space and is expensive to store solar energy
        
        Transportation and installation of solar systems have been associated with the emission of greenhouse gases.
      - Defined: Collects energy from the sun in the form of heat instead of energy. Used to provide space heating and water heating.
        2 types:
        Passive heating: Using the structure of a house to store heat and use it. (ex. Insulated building with glass windows can trap heat and use it)
        Active heating: Pumps and mechanical components are used to circulate the heat
      - Sample Problem
      - Pros
        
        Endless amounts of energy, free of charge
        
        No CO2 emissions during operation
        
        Cost savings: remarkable less energy to heat water, remarkable less energy for space heating
        
        Reduced consumption of fossil fuels
        
        Solar thermal systems can be integrated into existing systems
        
        Modern systems work efficiently even in winter
  - - - Renewable and sustainable
      - Water always flows (pretty reliable)
      - generally good for the environment
    - - expensive
      - disrupts animal migration paths, issues with water quality, and human or wildlife displacement.
      - not flexible: has to be a flowing source of water
  - - - Is a clean energy source and does not put any strain on the environment. The energy is completely renewable and very attractive when thinking of preserving the planet
      - Low operating cost and efficient use of land space (in terms of energy produced/land space taken up by contraption)
    - - Turbine Recycling
        
        Wind Turbines cannot be recycled, meaning that they just pile up in landfills (unless they are sent to a very ideal recycling site with powerful cutters as the blades are made of fiberglass)
      - It also causes noise and visual pollution, so it is important to consider those when thinking of installing wind turbines within an area
      - Intermittent, meaning that the energy provided is produced in irregular intervals and not produced constantly
    - - It is energy that uses wind to power contraptions via the generating of mechanical energy
      - It can be defined via;
        Wind Power = (1/2)(Air density)(frontal area)(Wind velocity)
        It is also important to note that this value will be multiplied by the efficiency of the system (known as the coefficient of performance) when considering total energy output
