Wind Turbines: How Physics Captures the Breeze

  1. Wind turbines convert kinetic energy from moving air into electricity.
  2. Blades act like airplane wings, creating lift that makes them spin.
  3. A rotor connects the blades to a shaft that drives a generator.
  4. The faster the wind, the more energy the turbine can produce.
  5. Turbines automatically adjust blade angle to maximize efficiency.
  6. Offshore wind farms capture stronger, steadier winds at sea.
  7. Modern turbines can stand over 250 feet tall with blades longer than a jet wing.
  8. Physics limits efficiency to about 59%, known as Betz’s Law.
  9. Wind power is renewable, producing no greenhouse gas emissions.
  10. Turbines now supply clean energy to millions of homes worldwide.
