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:
“A wind has started a little whirlpool
of sand where the carpet ought to be,
and shells lie
by the preposterous feet
of that woman who frets me, annihilates me,
O she will kill me yet.”
—Hilda Doolittle (1886–1961)
“Just as we are learning to value and conserve the air we breathe, the water we drink, the energy we use, we must learn to value and conserve our capacity for nurture. Otherwise, in the name of human potential we will slowly but surely erode the source of our humanity.”
—Elaine Heffner (20th century)
