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:
“The older you get the stronger the wind gets—and it’s always in your face.”
—Jack Nicklaus (b. 1940)
“In the west, Apollo and Dionysus strive for victory. Apollo makes the boundary lines that are civilization but that lead to convention, constraint, oppression. Dionysus is energy unbound, mad, callous, destructive, wasteful. Apollo is law, history, tradition, the dignity and safety of custom and form. Dionysus is the new, exhilarating but rude, sweeping all away to begin again. Apollo is a tyrant, Dionysus is a vandal.”
—Camille Paglia (b. 1947)
