The average blade length of a typical onshore wind turbine is about 165 feet (50 meters), but there is a trend towards taller turbines, particularly offshore, where blades can span up to 260-290 feet (80-90 meters). Wind turbine blade technology has evolved dramatically over the.

Rare earth minerals, specifically neodymium and praseodymium, play a critical role in the manufacturing of certain wind turbines, particularly those with permanent magnet generators (PMG), often used in offshore and direct-drive designs.

Wind turbines work on a simple principle: instead of using electricity to make wind—like a fan—wind turbines use wind to make electricity.
