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:
“... some of my people could have been left [in Africa] and are living there. And I can’t understand them and they don’t know me and I don’t know them because all we had was taken away from us. And I became kind of angry; I felt the anger of why this had to happen to us. We were so stripped and robbed of our background, we wind up with nothing.”
—Fannie Lou Hamer (1917–1977)
“Viewed narrowly, all life is universal hunger and an expression of energy associated with it.”
—Mary Ritter Beard (1876–1958)
