Wind Turbines: the Bigger, the Better | Department of Energy
A turbine's rotor diameter, or the width of the circle swept by the rotating blades (the dotted circles in the second illustration), has also grown over the years. Back in 2010, no turbines in the United States employed rotors that were 115 meters (380 feet) in diameter or larger. In 2020, 91% of newly installed turbines featured such rotors.

Tip Speed Ratio provided by Kid Wind
Calculating the Tip Speed Ratio of Your Wind Turbine The Tip Speed Ratio (TSR) is an extremely important factor in wind turbine design. TSR refers to the ratio between the wind speed and the speed of the tips of the wind turbine blades. Fast TSR (λ) = If the rotor of the wind turbine spins too slowly, most of the wind will pass straight

Wind Turbine Speed | TurbineGenerator
Angular speed is the measurement of degrees traveled per unit of time. For example the minute hand on a clock rotates at 360 degrees / hour. It can also be measured in radians / hour. Every point on the wind turbine blade has the same angular speed because each point rotates 360 degrees in the same unit of time.

How Does Wind Turbine Generate Electricity | Earth and Human
When the rotor spins, then the shaft also turns with its flow. In such a manner, the rotor transfers its mechanical, rotational energy to the shaft, which enters an electrical generator on the other end. A high-speed shaft drives the generator, whereas the low-speed shaft turns it at about 30-60 rpm. Generator

5 Top Wind Turbines for Low Wind Speeds - Green Home Gnome
The first thing you need to know is that wind power is proportional to the cube of wind speed, meaning that if a turbine generates 1 KW at 10 mph, that same turbine will generate 8 KW at 20 mph (double the wind speed 3 = 2 x 2 x 2). That's the reality of wind energy. Luckily, newer wind turbines are designed to work in wind speeds as low as 0 ...
