Wind power captures the natural wind in our atmosphere and converts it into mechanical energy then electricity. This is not exactly new technology. Humans have been harvesting the wind for centuries, starting with windmills to pump water, process grain, and generate power.
Today's wind turbine is a highly evolved version of a windmill. Modern wind turbines harness wind's kinetic energy and convert it into electricity. Most wind turbines have three blades and sit atop a steel tubular tower, and they range from 80-foot-tall models that can power a single home to utility-scale models that can be up to 700 feet tall and power thousands of homes.
