Known as windtechs, wind turbine service technicians install and repair wind turbines, which convert wind energy into electricity. Windtechs inspect towers and turbines, perform routine maintenance, replace malfunctioning components, and record data.

These technicians usually work outdoors and in pairs at elevations of around 260 feet while carrying tools and wearing harnesses. Electrical generation companies employ many of these professionals, but some work in repair and maintenance or in utility system construction.
