Company gives retired wind turbine blades new life
A wind turbine usually lasts 20 years or more. But at the end of its life, its giant blades often end up in a landfill. That's because many turbine blades are built out of a composite material made of glass fibers mixed with a hardened resin or other polymer. Recycling this composite material is difficult. But a company called Carbon Rivers ...

How a Wind Turbine Works
A wind turbine turns wind energy into electricity using the aerodynamic force from the rotor blades, which work like an airplane wing or helicopter rotor blade. When wind flows across the blade, the air pressure on one side of the blade decreases. The difference in air pressure across the two sides of the blade creates both lift and drag.
