how has the traditional use of wind or water energy been modified for our convenience???
Answers
Traditionally, waterfalls were used as a source of potential energy in which water is allowed to fall on the blades of the turbine where the rotatory motion of the blades of the turbine is converted into electrical energy. But waterfalls are few in number therefore water dams have been constructed. Nowadays, hydro-electric power stations are used in order to harness potential energy of stored water.
Earlier, the windmills were used to harness wind energy to do mechanical work such as lifting or drawing water from a well. But now a day’s windmills are used to generate electricity. In windmills the rotatory motion of the blades turns the blades of turbine to generate electricity.
Answer:
To use energy of flowing water large dams are built in hilly regions to store huge amount of water at a height. This water is used to produce hydroelectricity.
Wind energy is used to generate electricity by using windmill that converts the wind energy into electricity.
