How Much Energy Does A Wind Turbine Produce?
Wind turbines work by converting the wind that passes through the spinning turbines into energy. They're about 40-50% efficient at doing this. The spinning blades of the turbine define a circle, with wind passing through the area of the circle being converted to energy. Remembering some basic high school maths, the area of a circle is pi x r 2.

How Do Wind Turbines Work? | Department of Energy
A wind turbine turns wind energy into electricity using the aerodynamic force from the rotor blades, which work like an airplane wing or helicopter rotor blade. When wind flows across the blade, the air pressure on one side of the blade decreases. The difference in air pressure across the two sides of the blade creates both lift and drag.

Wind is actually a form of solar energy. Winds are caused by the heating of the atmosphere by the sun, the rotation of the Earth, and the Earth's surface irregularities. For as long as the sun shines and the wind blows, the energy produced can be harnessed to send power across the grid. Wind turbines can be built on existing farms or ranches.

How Much Energy Does A Wind Turbine Produce?
A modern wind turbine begins to produce electricity when wind speed reaches 6-9 miles per hour (mph) and has to shut down if it exceeds 55 mph (88.5 kilometers per hour) when its mechanism would be in danger of sustaining damage. So, while they can generate electricity for much of the time, there are other times they have to be shut down.

A wind turbine works by catching the energy in the wind, using it to turn blades, and converting the energy to electricity through a generator in the part of the turbine called a nacelle. The turbine is only one part of the system, however. A tower will put the blades high in the air where the wind is better.
