Question

how has the traditional use of water energ been modified for our convenience?write any two limitations of it.​

Answer 1

The kinetic energy of wind was traditionally used to do mechanical work like pulling water from a well or lifting. Nowadays, we can generate electricity using windmills. The potential energy of stored water at a height and the kinetic energy of flowing water were traditionally used to do mechanical energy. Nowadays, hydroelectric power stations are built to make use of the energy of water to generate electricity.

Answer 2

Explanation:

Earlier, the windmills were used to harness wind energy to do mechanical work such as lifting/drawing water from a well. Today, windmills are used to generate electricity.In windmills, the kinetic energy of wind is harnessed and converted into electricity.

Water energy which was used for transportation before is now a good source to generate electricity. Dams has been constructed on river for generating electricity. Waterfalls were used as a source of potential energy which was converted to electricity with the help of turbines.
