Electricity in nature

Here is a wind turbine in it is use to converts kinectic energy from the wind into mechanical energy.                                                                                                                         
If the mechanical energy is used to drive machinery, such as for grinding grain or pumping water, the device is called a windmill or wind pump.
Developed for over a millennium, today's wind turbines are manufactured in a range of vertical and horizontal axis types.
 The smallest turbines are used for applications such as battery charging or auxiliary power on sailing boats; while large grid-connected arrays of turbines are becoming an increasingly large source of commercial electric power.
