You may write about the process with which the wind mill works and where it is used.
Explanation:
Wind can be harvested for energy through wind mills which are common in high wind areas of the world. They propel themselves with the wind and then the mechanical energy is turned into electrical energy inside the turbines to generate electricity.
They are extremely useful in high altitude and grasslands where the wind blows with great speed throughout the year and can be a source of electricity which is sustainable.
