How is the energy in the wind captured?

  • Wind turbines, are like aircraft propeller blades that turn in the moving air. They power an electric generator, which supplies electrical energy.
  • Modern wind turbines fall into two basic groups
  • Horizontal-axis variety, like the traditional farm windmills used for pumping water
  • Vertical-axis design, like the eggbeater-style Darrieus model, named after its French inventor.
