Wind & solar

• Wind powers can be captured by wind turbines
• Wind turbines are located in exposed areas
• What is inside a wind turbine?

  Generator
• What happened to the generator when the blades turn due to wind

  The generator also turns
• What does the generator convert the kinetic energy into

  Electrical energy
• Where is the electrical energy transported

  The national grid
• Solar power is generated by solar cells, which are in the form of solar panels
• where do solar panels generate electric currents from

  Directly from the sunlight
• Solar work best in:


  Low power devices and remote regions
• Most solar is being used …


  On a larger scale to generate electricity for a whole town
• Pro:

  Both wind and solar have low running costs and don’t produce any pollution
• Con: they have upfront costs and the process of making them does produce pollutants especially solar cells
• Con: they are both dependant on the weather. If there’s no wind or sunlight no electricity is produced meaning no way to supply if it’s peak on demand
• Con: take up a lot of space, complains can include they are unflattering and noisy
