In order to maximize investments in wind turbine farms, and generate as much electricity as possible, wind turbines are being built taller where local regulations permit it. When designing taller turbines, engineers must reduce the size of installations within the nacelles- this reduces raw material use as well as safer working conditions for wind turbine technicians.
