Wind Turbines: Harnessing the Power of the Wind for Renewable Energy

Wind turbines, resembling giant futuristic windmills, convert wind into electricity by reversing the function of a fan. The wind turns the blades, powering a generator to produce electricity. Typically, wind turbines have three blades and can be as large as semi-trucks or buildings, with some models standing over 600 feet tall. Wind power is a popular, environmentally friendly energy source because it does not pollute the air and utilizes free wind, making it a renewable energy option.

What is the primary function of a wind turbine?
