Most turbines being set up 2012 in Europe are rated in the 1.5 MW to 3 MW range, 4 MW and 6 MW units have been set up but still are very few; 7 and 10 MW units are on the drawing boards of most large manufacturers.
As a rule of thumb some projectors calculate that a turbine will produce the rated power for 30% of the years 8760 hours. A 3 MW unit will then produce close to 7.9 GWh per year
Wind turbine manufacturers vary a little, but those such as General Electric (GE) produce a 1.5-megawatt model that is the industry average. This mean that if the wind blows within the ideal range, between 27 and 56 mph, a 1.5 MW wind turbine will produce power at the rate of 1.5 MW, its rated capacity. GE and others companies are producing turbines in the 2.5 to 3 MW range now, and research continues to develop even greater producing turbines.
All wind turbines have a range of wind speeds, usually this is from 30 to 55 mph. It is in this range that turbines will produce at rated, or maximum capacities. When the wind speed is slower, power output drops. For instance, if the wind speed falls to half of the rated capacity production decreases at a factor of eight. Turbine industry manufacturers estimate that annual output for most turbines is actually around 35% annually. Real world estimates put that power output at about 22.5% annually.
Here's another way to look at it:
The power output of a 1.5 MW turbine that produces for one year at 25% will produce 3,285 MWh (Mega Watt hours), equal to 3.285 million kWh (Kilowatt hours) during that year.
Total worldwide wind generated power output for 2008 was 121 GW (Gigawatts) -- 1 GW = 1,000 Megawatts = 1,000,000 Kilowatts = 1,000,000,000,000 watts.
For a better comparison, 1 kW equals about 1.34 horsepower. The average American home uses about 8,900 kilowatt-hours, or about 1kW continuously during the whole year.

What are some disadvantages about wind mills?
Some times to much wind is entered into the wind mill so the wind mill might not be able to produce much or any energy.
1000 watt wind mill generates how much energy?
1000 joules every second
Is a windmill thermal energy?
A wind mill does generate some heat but primarily it converts the kinetic energy in the wind into electrical energy.
How does wind create energy?
the wind rotate the wings of the wind mill this is kinetic energy this energy converted as mechanical energy this converted as electrical energy in generator thus produces power
What is the basic principle of wind mill?
The basic principle behind the wind mill is that the wind as an external force changes the static force to a kinetic force(from rest to motion).This kinetic energy rotates the wind mill blades which produces electricity.
What are some disadvantages about wind?
Some times to much wind is entered into the wind mill so the wind mill might not be able to produce much or any energy.
What are some disadvantages about wind mills?
Some times to much wind is entered into the wind mill so the wind mill might not be able to produce much or any energy.
Is a wind mill nonrenewable energy?
Wind turbines produce renewable energy. Energy is considered renewable when it is created by a source that is inexhaustible.
How can wind make power?
If you have wind mills, the wind can give a lot of electricity because the mill will absorb the amount of potential energy needed to produce the amount of kinetic energy.
How does wind electricity work?
The wind electricity work because of the wind mill, wind mill makes wind energy.
What energy is generated by a wind mill?
electrical energy
What products do you get from wind energy?
Depends. Some wind turbines "only" produce electric energy. Others, like old wind mills, directly powers machinery, like mills or pumps. A mill would then produce flour, and a pump would move liquids.
1000 watt wind mill generates how much energy?
1000 joules every second
How is wind energy obtained?
Wind energy is generally captured with windmills.The term windmill was actually termed to describe using wind to produce mechanical energy to run a mill such as a grain mill to produce flower.In the USA, many of the early windmills powered mechanical pumps for water, especially water to feed animals in remote areas.Most modern windmills incorporate a generator and are now used to produce electricity rather than mechanical energy.
How much wind does the US produce to the worlds wind energy?
Wind power is not generated by countries, it is a global phenomena.
How do you produce energy with wind?
Windmills and wind turbines are good sources to produce energy.
Does wind energy produce renewable energy?
Wind energy is renewable energy.
