Wind turbine blades might cease rotating due to several circumstances, such as rapid or sluggish wind speeds and adverse weather conditions. The turbines will cease spinning if they cannot get any energy from the wind or if their blades are damaged by too fast movement.
With a capacity to generate 15 megawatts of power, the Vestas V236‑15. 0 MW is the largest and most powerful wind turbine as of 2025 to have been commercially deployed.
The United States Department of Energy reports that most modern land-based wind turbines have blades of over 170 feet (52 meters), resulting in a total rotor diameter longer than a football field.
A wind turbine's electricity generation varies significantly based on size and wind conditions, but typical modern utility-scale turbines generate between 2 to 3 megawatts (MW), equivalent to 2000-3000 kilowatts, while smaller residential turbines might produce only a few kilowatts.
A single unit can generate 68 million kilowatt-hours of clean electricity annually, enough to power approximately 40,000 households. The turbine will undergo real-world testing in the waters off Yangjiang, in south China's Guangdong Province, according to China Huaneng Group.
