Wind Energy
Wind energy is the kinetic energy of the air in motion. Total wind energy flowing through an imaginary area A during the time t is:
- E = A·v·t·ρ·½ v2,
where v is the wind velocity and ρ is the air density. The formula presented is structured in two parts: (A·v·t) is the volume of air passing through A, which is considered perpendicular to the wind velocity; (ρ·½ v2) is the kinetic energy of the moving air per unit volume.
Total wind power is:
- P = E/t = A·ρ·½ v3
Wind power is thus proportional to the third power of the wind velocity.

Famous quotes containing the words wind and/or energy:
“There, beyond the dykes
I heard wind flaking sapphire, like this summer,
And willows could not hold more steady sound.”
—Hart Crane (1899–1932)
“The principle of avoiding the unnecessary expenditure of energy has enabled the species to survive in a world full of stimuli; but it prevents the survival of the aristocracy.”
—Rebecca West (1892–1983)
