How much energy do wind turbines produce a year?

Answer 1

This depends on the size of the turbine and the wind resource. A single 1MW turbine operating at a 45% production rate will generate about 3.9 million kW of electricity in a year. This would be enough to meet the needs of about 500 households per year.

The world's largest turbine, the Enercon E-126 has a rated capacity of 7.58 MW have been constructed at Emden, in Germany in 2007. Several companies are developing 10 MW turbines.

A:Once you take away the wasted fossil fuel for plants on standby, the cost of maintenance and the inefficiencies associated with the wind turbines of today you end up with about 5% of rated power. Even when running they average 8% of rating.

A 1 million watt system will typically generate about 80,000 watts of power each hour. This is further offset when you add into the equation that a power plant is running in the background to supply the backup power as wind velocities change.

Units range in size from 400 watts to a 5 megawatt system. As systems increase in size they reduce efficiency and kill more birds and bats (Massachusetts loses 100K birds a year to wind systems),

Once everything is added up they produce less power then it takes to build a unit.

A:The World Wind Energy Association, an industry organization, reported that in 2010, wind power had the capacity to generate 430 TWh annually. This is about 2.5% of total energy generated worldwide.

(430 Terawatts is 430 million million kilowatt hours: 430,000,000,000,000 kWh)

Answer 2

The amount of energy produced by wind turbines in a year can vary depending on factors such as location, size of turbines, wind speeds, and maintenance. On average, a modern wind turbine with a capacity of 2-3 MW can produce between 4 to 7 million kilowatt-hours (kWh) per year, which is enough to power around 1,000 to 2,000 homes.
