Over the past several years, however, many new fibers have become available. The commercially available fibers and their typical properties are listed in Table While E-glass fiber is most widely used in wind turbine rotor blades mainly because of its low cost, carbon fibers are the fibers of choice in many aerospace   It’s certainly amusing to see a wind turbine brought down by the wind.

But of course the only ‘promise’ of wind power is huge energy bills and endless power cuts if – heaven forbid – wind power becomes a major power source (our UK government is aiming for about 30%, a completely mad fantasy).
