Wind turbines turn energy from the wind into electricity. Turbines turn so that they face into the wind. The turbine blades are shaped so that even low winds will push them round.Kinetic energy ...
How Do Wind Turbines Work? | Department of Energy
Wind turbines work on a simple principle: instead of using electricity to make wind—like a fan—wind turbines use wind to make electricity. Wind turns the propeller-like blades of a turbine around a rotor, which spins a generator, which creates electricity.

How a Wind Turbine Works
Most turbines have three blades which are made mostly of fiberglass. Turbine blades vary in size, but a typical modern land-based wind turbine has blades of over 170 feet (52 meters). The largest turbine is GE's Haliade-X offshore wind turbine, with blades 351 feet long (107 meters) – about the same length as a football field.
Life cycle assessment of two different 2 MW class wind turbines
Turbine 2.0 MW-geared is a wind class IEC IIA turbine specially designed for the wind regimes of continental Europe. The second turbine to be analysed is a 1.8 MW turbine without gearbox (from now on referred to as turbine 1.8 MW-gearless). This wind turbine is already in operation and operating data is available.
Wind Power! Designing a Wind Turbine
Wind turbines need wind speeds of at least 15 kilometers (9 miles) per hour, for small wind turbines, and 21 kilometers (14 miles) per hour, for utility-scale turbines. Wind turbines are best located in areas in which wind speeds are 26-32 kph (16-20 mph) with the windmill at 50 meters (55 yards) high. That's pretty high up.
Wind turbine fundamentals
The wind turbine project timeline depends on the scale of the project, the site complexity and environmental sensitivity. For a typical single 1 MW wind turbine project the minimum a project duration would be two years, broken down as shown on the chart below. This could easily extend to 2 ½ years with any project complications arising.
