3. Wind turbine - Wikipedia

   en.wikipedia.org/wiki/Wind_turbine

   Nashtifan wind turbines in Sistan, Iran. The windwheel of Hero of Alexandria (10–70 CE) marks one of the first recorded instances of wind powering a machine. [5] However, the first known practical wind power plants were built in Sistan, an Eastern province of Persia (now Iran), from the 7th century.

4. Outline of wind energy - Wikipedia

   en.wikipedia.org/wiki/Outline_of_wind_energy

   Wind turbine aerodynamics – the power, F, is the force vector, and U is the speed of the moving wind turbine part. Wind turbine design – the process of defining the form and specifications of a wind turbine to extract energy from the wind. Types of wind turbines

5. Wind power - Wikipedia

   en.wikipedia.org/wiki/Wind_power

   Wind power is considered a sustainable, renewable energy source, and has a much smaller impact on the environment compared to burning fossil fuels. Wind power is variable, so it needs energy storage or other dispatchable generation energy sources to attain a reliable supply of electricity. Land-based (onshore) wind farms have a greater visual ...

6. Wind-turbine aerodynamics - Wikipedia

   en.wikipedia.org/wiki/Wind-turbine_aerodynamics

   Wind-turbine blades in laydown yard awaiting installation. The primary application of wind turbines is to generate energy using the wind. Hence, the aerodynamics is a very important aspect of wind turbines. Like most machines, wind turbines come in many different types, all of them based on different energy extraction concepts.

8. Betz's law - Wikipedia

   en.wikipedia.org/wiki/Betz's_law

   The power coefficient [9] C P (= P/P wind) is the dimensionless ratio of the extractable power P to the kinetic power P wind available in the undistributed stream. [ citation needed ] It has a maximum value C P max = 16/27 = 0.593 (or 59.3%; however, coefficients of performance are usually expressed as a decimal, not a percentage).

9. Yaw system - Wikipedia

   en.wikipedia.org/wiki/Yaw_system

   The necessary yawing torque was created by means of animal power, human power or even wind power (implementation of an auxiliary rotor known as fantail). Vertical-axis wind turbines (VAWTs) do not need a yaw system since their vertical rotors can face the wind from any direction and only their self rotation gives the blades a clear direction of ...
