There is a good introductory article on wind power in Home Power magazine issue 127 (October/November 2008) titled "Wind Power Curves".
The quick summary is that the theoretical limit for energy capture (the Betz limit) is 59.6% of the energy in the wind.
The wind energy available depends on the wind speed. If the average wind speed is known, the available energy can be calculated assuming some standard distribution (normally Rayleigh distribution) of wind speeds.
Some sample figures (based on Rayleigh wind distribution and 35% turbine efficiency):
5mph average -> 0.25 kWh/month/sq.ft
10mph average -> 2.08 kWh/month/sq.ft
The power figure is per square foot of swept area (the area covered by the turbine blades when rotating), so if you have 100 sq. feet swept area then 10mph average wind speed could generate 208kWh/month.

How a wind power system produce electricity?
The wind turns a wind turbine. The turbine turns a generator.
How much energy does wind produce?
A typical utility scale wind turbine will produce anywhere from 1.5 megawatts to 3.0 megawatts. This means that a single wind turbine can power about 300 average households annually.
How many homes does one wind turbine power?
one wind turbine can produce enough energy to power 10000 houses with the right amount of wind.
A wind turbine uses the power of the wind to produce nuclear energy?
What are you smoking?
What kind of machine uses wind to produce power?
A wind turbine is a machine that uses wind to produce power. The kinetic energy of the wind rotates the turbine's blades, which then drive a generator to generate electricity.
How much wind does a wind turbine produce in a day?
depends on if it works
How is the power-station the same as a wind powered turbine?
They both produce electricity
How much power does a wind turbine create?
The Power Generated by a Wind Turbine entirely depends on the capacity of the turbine which is installed.. there are turbines ranging from 1 watt to 10 MW that can be installed in a wind farm The installation of the turbine depends on the Wind Potential of the area.
How much energy does wind power produce?
The amount of energy produced by wind power has several different factors, such as the amount and strength of the wind. However, some studies show that a 1.8 MW wind turbine can produce over 4,700,000 kWh of energy per year if located at a reasonable site.
Why isn't wind energy used to produce all your energy?
Because a wind turbine doesn't necessarily produce enough energy and is at the mercy of the wind. No wind = no power so really it's an illogical way to power a house or town.
How can you generate power using a mini wind turbine?
To generate power using the mini wind turbine you will have to install a small wind turbine and connect it to the grid.
What is the big machine to produce energy from wind?
Wind Turbine.
