Windmills convert kinetic wind energy into mechanical power. Wind provides the energy required to turn the vanes of a windmill, which can be connected to a generator to generate electricity or used as a source of mechani... More » Science Physics Electricity

Windmill generators work by capturing the kinetic energy of blowing air and converting it to electric energy using copper coils and magnets. The wind pushes the wind turbine blades, which turn an axle. The axle, usually ... More » Science Physics Electricity

Windmills produce electricity by electromagnetic induction, the process in which the movement of magnets in a magnetic field generates electricity. In a windmill, when wind moves the blades of the windmill that move the ... More »

Wind turbines turn the kinetic energy of the wind into mechanical energy and then electricity through the use of a shaft and a gearbox that power an internal generator. Sensors in the wind turbine allow it to turn and ad... More »

Wind energy is a form of renewable energy produced through machines that use wind as their power source. Wind energy is only possible because of the sun. More »

According to National Geographic, electricity comes from energy sources such as fossil fuels, wind energy and hydroelectric power. Electricity is transported from a power station via power lines that carry electrical cur... More »
