Wind and Solar

Cards (16)

  • What two types of power are discussed in the video?
    Wind and solar power
  • What will be considered at the end of the video?
    The pros and cons of wind and solar power
  • How is wind power captured?
    Through the use of wind turbines
  • Where are wind turbines generally placed?
    In exposed areas like malls or coasts with strong winds
  • How do wind turbines generate electricity?
    The blades spin in the wind, turning a generator that converts kinetic energy into electrical energy
  • What is solar power generated by?
    Solar cells, often in the form of solar panels
  • How do solar cells generate electric currents?
    Directly from sunlight, similar to how plants trap energy through photosynthesis
  • In what two scenarios do solar panels work particularly well?
    In low energy devices like watches and calculators, and in remote regions not connected to the main power grid
  • What is the current trend in the use of solar energy?
    It is increasingly being used on a larger scale to generate electricity for entire towns
  • What are the pros and cons of wind and solar energy?
    Pros:
    • Very low running costs
    • No pollutants produced, including carbon dioxide

    Cons:
    • High upfront costs
    • Production processes can create pollutants
    • Dependent on weather conditions
    • Require a lot of space
    • Aesthetic and noise complaints regarding wind turbines
  • What is a major limitation of both wind and solar energy?
    They are both dependent on weather conditions
  • What happens if the wind doesn't blow or the sun doesn't shine?
    They do not generate any electricity
  • What is a common complaint about wind turbines?
    They don't look very nice and are too noisy
  • How do wind and solar energy impact the environment?
    Neither wind nor solar energy damage the environment
  • What is the trend regarding the costs of wind and solar energy?
    Both are getting cheaper every year
  • What is the conclusion of the video?
    It summarizes the discussion on wind and solar power
