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 disadvantages of windmills include their potential impact on local wildlife, such as birds and bats, the intermittency of wind as a power source, which can require additional energy storage solutions, and the visual impact they may have on the landscape, which can be seen as unsightly to some people.
Does flour mill run on wind energy?
A flour mill typically runs on electricity generated from a power source such as fossil fuels, hydroelectricity, or wind energy. In some cases, a flour mill can be powered by wind energy if it is equipped with a wind turbine to generate electricity.
How does a wind mill works and describe about its working?
A windmill converts wind energy into mechanical energy by using the force of the wind to turn its blades. The blades are connected to a rotor, which spins a generator to produce electricity. The electricity generated can then be used to power homes or businesses.
How does wind power work?
Wind power works by capturing the energy from the wind with wind turbines. When the wind blows, it causes the turbine blades to spin, which drives a generator to produce electricity. This electricity can then be used to power homes, businesses, and other structures.
Is wind a source of energy?
Yes, wind is a renewable source of energy that can be harnessed to produce electricity through wind turbines. Wind energy is considered clean and sustainable, as it does not produce greenhouse gas emissions during its operation.
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.
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.
What are some disadvantages about wind mills?
Some disadvantages of windmills include their potential impact on local wildlife, such as birds and bats, the intermittency of wind as a power source, which can require additional energy storage solutions, and the visual impact they may have on the landscape, which can be seen as unsightly to some people.
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.
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.
Does flour mill run on wind energy?
A flour mill typically runs on electricity generated from a power source such as fossil fuels, hydroelectricity, or wind energy. In some cases, a flour mill can be powered by wind energy if it is equipped with a wind turbine to generate electricity.
How do you produce energy with wind?
Windmills and wind turbines are good sources to produce energy.
A large wind turbine generate more or less energy?
A large wind mill generates more energy compared to the smaller sized wind mill as it can capture more wind energy i.e.its Plant load factor/Capacity factor is higher.
