== <span style="color: #FFFFFF;">Remembering</span> == * '''Wind Energy''' β The "Harnessing" of "Airflow" to "Drive" "Mechanical Turbines." * '''Kinetic Energy''' β (See Article 21). The "Energy" of "Movement": a "Wind Turbine" "Steals" some of this energy to "Slow Down" the wind. * '''Betz's Law''' (Betz Limit) β The "Theoretical Maximum" of "Wind Energy Extraction" (~59.3%). You "Cannot" take 100% of the energy, or the wind would "Stop," and no more wind could come through. * '''Horizontal-Axis Wind Turbine''' (HAWT) β The "Standard Look": a "Propeller" on a "Tower" that "Faces" the wind. * '''Vertical-Axis Wind Turbine''' (VAWT) β A "Spinning Cylinder" or "Eggbeater" shape that works with "Wind from Any Direction." * '''Nacelle''' β The "Box" on top of the tower containing the "Gearbox" and the "Generator." * '''Yaw System''' β The "Motor" that "Rotates" the turbine to "Face" the wind as it "Changes Direction." * '''Cut-in Speed''' β The "Minimum Wind Speed" (~3-4 m/s) needed to "Start" the turbine. * '''Rated Power''' β The "Maximum Power" a turbine can produce (Usually reached at ~12-15 m/s). * '''Offshore Wind''' β Wind farms "Built in the Ocean": the wind is "Stronger" and "Smoother," allowing for "Massive" turbines. </div> <div style="background-color: #006400; color: #FFFFFF; padding: 20px; border-radius: 8px; margin-bottom: 15px;">
