Wind energy is a renewable energy source that has been harnessed by humans for centuries. Today, wind energy is typically used to generate electricity through the use of wind turbines. Wind turbines are large, tower-like structures that are equipped with blades that rotate when the wind blows. As the blades turn, they spin a generator that produces electricity. Large wind farms, which are collections of many wind turbines, are often built in areas with strong and consistent winds, such as on hills or in coastal regions. The electricity generated by wind turbines can be used to power homes, businesses, and even entire cities. Wind energy is considered to be a clean and sustainable source of energy, as it does not produce harmful emissions or contribute to climate change.
