A wind turbine works like a fan but in reverse: instead of using electricity to make wind like a fan, wind turbines use wind to make electricity..
When the wind blows, it makes the blades of the fan, called rotors, spin around, which moves the turbine on the inside and generates electricity..
The Office of Energy Efficiency and Renewable Energy describes a wind turbine as “ the opposite of a fan.” Simply stated, the turbine takes the energy in that wind and converts it into electricity..
Wind energy is a form of renewable energy, typically powered by the movement of wind across enormous fan-shaped structures called wind turbines. [pdf]
Forty years ago, wind turbine blades were only 26 feet long and made of fiberglass and resin . Today, blades can be 351 feet, longer than the height of the Statue of Liberty, and produce 15,000 kW of power. Modern blades are made from carbon-fiber and can withstand more stress due to higher strength properties. They. .
Longer blades create more efficient turbines; however, they also put more mechanical stress on the structure, so it requires lighter materials. .
The limit to the maximum size of a wind turbine blade involves the point of inflection, when the blades begin to bend and flex. Longer blades are more flexible which also creates more. [pdf]
