Wind turbines are an increasingly important source of intermittent renewable energy, and are used in many countries to lower energy costs and reduce reliance on fossil fuels.
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.
The term windmill, which typically refers to the conversion of wind energy into power for milling or pumping, is sometimes used to describe a wind turbine. However, the term wind turbine is widely used in mainstream references to renewable energy (see also wind power).
The wind energy sector is experiencing unprecedented growth in 2025, with global wind capacity expected to reach new heights. Whether you’re a homeowner considering a residential wind turbine or an investor evaluating commercial wind farm opportunities, understanding wind turbine costs is crucial for making informed decisions. Wind turbine prices range dramatically from $700 for small ...

A simple explanation of how wind turbines generate electric power, including a comparison of full-size and micro turbines.
Wind turbines use blades to collect the wind's kinetic energy. Wind flows over the blades creating lift (similar to the effect on airplane wings), which causes the blades to turn. The blades are connected to a drive shaft that turns an electric generator, which produces (generates) electricity.
