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 ...

Six Northern Power 100 kW direct drive wind turbines produce power for Unalakleet, Alaska. The turbines are owned by Unalakleet Valley Electric Cooperative. Photo courtesy STG Inc. For years, wind ...

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 ...

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 ...

As the renewable energy sector continues to grow, so does the complexity of technology and equipment such as wind turbines, solar arrays, and transmission infrastructure. Gear oils and lubricants are ...

• 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.
