*Cost and price · Moderate · Both ways*

Most wind turbines use a large gearbox between rotor and generator, and gearbox failures are a major maintenance cost. The turbine proxy correlates at 0.53 for yearly moves, but monthly moves show almost nothing, at 0.05.

- **0.05** monthly change correlation
- **0.53** 12-month change correlation
