Question 3 Page 248 - Chapter 14 Class 10 - Sources of Energy

How has the traditional use of wind and water energy been modified for our convenience?

Answer

Wind energy

Traditionally, wind energy was used through windmills to lift water from a well and to grind wheat into flour.

Now, the traditional use of wind energy has been modified.

Now wind energy is used to generate electricity through wind-powered generators. 

Water energy

Traditionally, we would use Water falls as a source of Water Energy.

But due to technological advancements, we have built dams which store the water at some height.

So, we can now store water at more height instead of the waterfall height.

And we can also make dams at places other than water falls.
