New blade technology makes more from wind - Windpower Monthly (subscription)

Turbine blades will play a growing role in the drive to reduce the cost of wind-generated electricity. They are expensive components, representing up to one-fifth of the manufacturing costs of an onshore turbine (one-tenth for an offshore machine) and that proportion is unlikely to reduce significantly in the near future, even with technology advances, says Roel Schuring, vice-president for engineering at Danish blade manufacturer LM Wind Power. But the new technology will make individual turbines work more efficiently, and cut wind energy costs generally. "The increasingly advanced blades have more benefits than 'just' creating more energy," says Schuring. "They also help to optimise loads on the turbine, which is the way to reduce the cost of other components. So the total cost of the turbine goes down, but the blades' share more likely will not," he says. In March, LM W...
