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. M. .
Longer blades create more efficient turbines; however, they also put more mechanical stress. .
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 vibr. Wind turbine blades range from under 1 meter to 107 meters (under 3 to 351 feet) long. [pdf]
