energy saving windmills

When the blowing wind strikes across the blades of a windmill, it exerts a force on them due to which the blades of the windmill start rotating. This in turn rotates the shaft of the turbine and generates electricity. ..

Wind energy has been extensively used for driving windmills for centuries. However they are used to operate water lifting pumps too. In a water pump a piston moves up and down and draws water from underground sources of water. The figure shows the design of a windmill ..

Kinetic Energy - It is a matter of common experience that a fast moving stone can break a windowpane, falling water can rotate turbines and moving air can rotate windmills and propel sailboats. In all these examples, the moving body possesses energy. Work is done by th..
