Wind turbines last longer than ever thanks to continuous engineering improvements. Gearboxes in wind turbines, more than those in any other application, tend to fail prematurely. In fact, at some wind ...

Wind power has always been a trade off between clean energy and the visual, acoustic, and ecological cost of giant spinning ...

Wind turbines are more reliable than ever, as evidenced by the uptime and availability numbers for today’s wind farms. It’s due in large part to wind-turbine gearboxes that have become increasingly ...

• Gearboxes with high step-up ratios tend to give horizontal wind turbines poor efficiency when wind speeds are low. • One way to eliminate wind-turbine bird kills: Locate turbines far out at sea.

Consider the inside of a typical wind turbine nacelle. It will contain a gearbox, electrical controls, a generator, hub mounting, blade controls, and several other major systems. In the case of ...
