Wind Power

Everything wind, from why air starts moving in the first place to how a turbine turns that movement into electricity. Explore turbines, blades, generators, capacity factors, offshore wind, grid integration and the economics of wind power.

What is wind power? How moving air becomes electricity

Wind power turns the kinetic energy of moving air into electricity—but a turbine doesn’t simply “catch” wind like a sail. From uneven solar heating and atmospheric pressure differences to aerodynamic lift, spinning generators, and grid-ready electricity, here’s what actually happens inside a wind turbine.
