  • Wind turbines spin when strong wind is directed at them.
  • Wind farms are groups of turbines in windy locations.
  • Turbine blades gain kinetic energy from air particle collisions.
  • The spinning turbine powers an electrical generator inside the tower.
  • The generator sends electricity to the national grid.
  • Gears control the turbine's safe spinning speed.
  • Wind energy is unreliable due to changing weather conditions.
  • Weak wind can't overcome turbine friction; strong wind can be dangerous.
  • Wind energy is used as a substitute for fossil fuels when conditions allow.
  • Wind energy is clean, renewable, and has low operating costs.
  • Disadvantages include weather dependency, potential harm to wildlife, and being considered an eyesore by locals.
  • Offshore wind farms avoid being an eyesore and have a more reliable wind source.
