An onshore wind turbine with a capacity of 253 MW can produce more than 6 million kWh in a year enough to supply 1500 average EU households with electricity. The implementation of wind energy is continuously growing and today about 79 countries have wind energy already in practice.

To serve more than 24 million households.
How much power does a wind turbine produce per day. The other term you need to understand is the related watt-hour A watt-hour is a unit that expresses how much energy a battery can hold. For example with a 25 capacity factor a 2-MW turbine would produce 2 MW 365 days 24 hours 25 4380 MWh 4380000 kWh per year. The larger the source the more water can spray through the hose.
A good residential wind turbine should have a rated power output of between 2 kW and 10 kW. Some of the largest wind turbines can produce up to 12 MW of electricity. The worlds largest wind farm is located in Texas at the Horse Hollow Wind Energy Center.
Thus if the wind speed doubles 2 times as much speed the power available goes up. Every wind turbine has a different range of wind speeds typically around 30 to 55 mph in which it will produce at its rated or maximum capacity. For the 4 kW wind turbine well assume the turbine is 40m high.
To find the 90 confidence interval ie. Although this is a fairly large number of households. This wind farm has 421 wind turbines which produce enough energy to power 220000 homes per year.
Using solar modelling software the 4 kW solar panel system outputs about 5679 kWh per year or 156 kWh per day on average. Obviously this rated capacity does not translate directly to electricity generated on a given day since you would also need to know the capacity factor of the wind turbines to know how often wind gets translated into power but knowing the average US. It is reckoned that an average onshore wind turbine rated at 25 3 megawatts can produce in excess of 6 million kWh every year.
In 2006 wind energy produced enough electricity in the US. Power available in the wind increases by a cube factor as related to increases in wind speed. To put it another way the average wind turbine generates enough energy in 94 minutes to power an average US.
How much energy do wind turbines produce. The mean wind speed of 665 ms provides a standard error of 55 and applying each newly rescaled time series to the power curve of a sample Gamesa G87 20 MW turbine at 80m whose MWh output is summed for the entire year for each. A small wind turbine may produce about 100-watts of energy on a blustery day whereas a larger unit may produce upwards of 1000-watts.
How much power does a wind turbine produce per rotation. Average energy per day is 900W x 24h 21600 Wh or 216 kWh. Wind turbines are getting bigger and producing more and more electricity all the time.
As a result wind turbines do not operate near their capacity but rather at about 1530. Wind turbines commonly produce considerably less than rated capacity which is the maximum amount of power it could produce if it ran all the time. At a 33 capacity factor that average turbine would generate over 402000 kWh per month - enough for over 460 average US.
P90 for the cumulative annual-energy production wind speed data from the 80m sensor is rescaled several times by randomly sampling errors from a normal distribution of annual mean wind speeds ie. Average wind speed is about 65 ms giving an average power output of 900W from power curve. Out of the 79 countries 24 are producing more than 1000 megawatts.
A small wind turbine that is rated at 400 watts would produce an average of 40 watts per hour at my location. Wind turbines manufactured today have power ratings ranging from 250 watts to 7 MW. A modern wind turbine produces electricity 70-85 of the time but it generates different outputs depending on the wind speed.
Wind turbine is rated for 1633 kW means you can expect it to be generating 1633 kW of power when the wind is cooperating. If the wind speed decreases by half power production decreases by a factor of eight. Home for one month.
Just because a wind turbine has a capacity rating of 15 megawatts that doesnt mean it will produce that much power in practice. A 36 MW offshore turbine may double that. At slower wind speeds the production falls off dramatically.
Moreover the capacity of wind turbines varies from one model or design to another. This is enough to power to around 16000 households per turbine each year.
