Although rare, a blade can break and fall if a growing fracture is undetected long enough. As with other wind-turbine equipment, detecting cracks and problems early enough makes repairs less expensive. “A preliminary market study found companies are trying to address the blade problem with more complex and expensive sensors, which need someone well versed with the technology. So a shortage of trained manpower would be a problem for them,” he said.
