it is roughly about 70 feet
413ft
Largest Wind Turbine is 7MW and 413 Feet Tall
You will need something tall to mount your turbine, propellers, a generator (if you're using it to make electricity), the land, and any other small pieces to hold your turbine together.
A wind turbine is a form of electric generation. On top of a tall pole there is a turbine (fan thing) and the wind spins it around. The turbine is connected to a motor which generates an electromagnetic flow from the motion.
the land where it stand
Approximately one acre.
A land owner with with wind turbines on their land get $3,000-4,000 a year. 1 wind turbine takes up 1/2 an acre of land. -Bethie
as much as 3 times its blades which are 45 meters
A wind turbine makes wind for scientific study.
The height of a wind turbine has no impact on the turbine's output wattage. The factors that effect the watts produced are: * The efficiency of turbine design (this is at most 59%) * the density of the air * the radius of the turbine (that is, the length of each fin) * the velocity of the wind passing through the turbine An 80 ft tall turbine would presumably have a fin length (that is, turbine radius) of at most 30 ft. Thus, at sea level on a 59 degree (F) day, in an 8 m/s (18mi/h) wind, with the most efficient turbine design possible, you would generate approximately 15.4 Kilowatts.

a wind turbine generates electricity for or use
one hundred wind turbines take up one kilometre of land
