How long were the blades of ancient wind turbines

How a Wind Turbine Works

The largest turbine is GE''s Haliade-X offshore wind turbine, with blades 351 feet long (107 meters) – about the same length as a football field. When wind flows across the blade, the air pressure on one side of the blade decreases. The difference in air pressure across the two sides of the blade creates both lift and drag.

The more energy there is in the air, the more power a wind turbine can make. It''s just like the water. The harder it''s hitting your hand, the more energy it has, so the more energy you could catch and turn into power. A wind turbine is built very high up in the air because the wind (the air) moves much faster there.
