How do wind turbines actually work?

Wind turbines can be either vertically or horizontally-mounted. The blades of the turbines, which are very similar to the 'arms' of a windmill, catch the wind as it blows. The wind causes the blades of the turbine to turn. As the blades of the turbine are rotated, the turbine's shaft moves, turning a generator. This generator produces electrical energy, which is converted into high-voltage electricity. The electricity is passed through cables, feeding into the power grid.
