Wind Energy
Electricity generated from wind turbines that convert kinetic energy of wind into electrical power.
Formula
P = ½ρAv³ (wind power; P = power, ρ = air density, A = swept area, v = wind speed)
Real World
The Hornsea Two offshore wind farm off the Yorkshire coast became the world's largest operational wind farm in 2022, with 165 turbines generating 1.32 GW — enough to power 1.4 million UK homes.
Exam Focus
The cubic relationship between wind speed and power (v³) is frequently tested — a doubling of wind speed increases power output eightfold.
