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 and improved design. Wind turbine. .
