The longer the blade... the more electricity generated [per similar speed]. If the wind blows too fast the wind turbine BRAKES [stops] so it doesn't BREAK [smash apart]! Force = mass x acceleration or F=ma Energy = Work = Force x distance or W=Fd Power = Work/time or P= W/t Kinetic Energy is energy in MOTION!
