How has the traditional use of wind and water energy been modified for our convenience?
The wind and water energy were traditionally used to pump water (lift water) from a well and to grind wheat into flour.
The traditional use of wind and water energy has now been modified by the improvement of technology to generate electricity through the wing powered generators and hydroelectric power plants respectively.
Wind Power Generators: A wind generator is used to generate electricity by using wind energy. When a fast moving wind strikes the blades of the wind turbine, the wind turbine rotates continuously. The shaft of a wind turbine is connected to a small generator. When the turbine rotates, the shaft also rotates to drive the generator and produce electricity.
Hydro Power Generator: A hydro power generator is used to generate electricity using the potential energy of the water stored in a dam. Water falling down from a height flows very fast and pushes the blades of the turbine to rotate continuously. The shaft connected to the turbine also rotates and drives the generator to produce electricity in the powerhouse.
