wind energy today offers one of the most economical sources of electricity in most countries across the world and is a major factor in driving a new era in a global energy transition.
Wind turbines, like windmills, are mounted on a tower to capture the most energy. They can take advantage of the faster and less turbulent wind at 100 feet (30 meters) or more above ground. Turbines catch the wind’s energy with their propeller-like blades. Usually, two or three blades are mounted on a shaft to form a rotor
Wind turbines can be used as stand-alone applications, or they can be connected to a utility power grid or even combined with a photovoltaic (solar cell) system. For utility-scale (megawatt-sized) sources of wind energy, a large number of wind turbines are usually built close together to form a wind plant, also referred to as a wind farm. Several electricity providers today use wind plants to supply power to their customers.
