Wind is caused by differences in atmospheric pressure created‚ in large part‚ by the unequal heating of the earth’s surface by the sun. Air moves from a region of higher pressure to one of lower pressure and this movement is wind. Any difference in pressure will cause wind‚ but the greater the difference the stronger the wind. The direction that wind takes is influenced by the rotation of the earth. On a non-rotating earth wind would move in a straight path from a high- to a low-pressure area. It

project is a mini windmill that uses wind energy to generate electricity. This process is achieved by creating a propeller and connecting it to a motor. This motor lies on a free rotating base that rotates above a stand (truss) that supports the whole mill. Rotating the base to face the direction of the wind is achieved by connecting a back rudder to the base. • How does it work? Electric energy generation starts when the wind rotates the propeller blades – that have
