Scaling to larger size is the primary approach used to improve the wind turbine cost per kWh.
Advances in generators, gearboxes, blade designs, blade materials and controls allow wind turbines to improve in performance and grow in size. Over the past 20 years, average wind turbine ratings have grown almost linearly, with current commercial machines rated at 1.5 MW.
Wind Turbine Major Components:
1] Wind turbine Rotors:
Existing technology: Carbon fibers have been incorporated into wind turbine blades for some years to provide localized strength.
