A wind turbine generates electricity by using the kinetic energy of wind to spin its blades, which are connected to a rotor. The generator then converts this mechanical energy into electrical energy. Wind flows over the blades creating lift (similar to the effect on airplane wings), which causes the blades to turn. . Wind energy has become one of the most powerful symbols of sustainable progress, capturing nature's invisible force and transforming it into electricity that fuels homes, industries, and cities around the world. This creates a pressure differential: Lift: The low pressure on the top "pulls" the blade forward.
