Question

why we using wind turbines?

Answer 1

Wind turbines convert the kinetic energy in the wind into mechanical power. This mechanical power can be used for specific tasks (such as grinding grain or pumping water) or a generator can convert this mechanical power into electricity to power homes, businesses, schools, and the like.

Answer 2

To generate electricity

generally coal is used to generate electricity but the amount of coal is reducing day by day also coal takes thousands of years to regenerate

but our electricity demands are increasing day by day

So we made wind turbines which have dynamos in them

dynamos are rotated by the wings of the wind turbines which are rotated by wind and thus electricity gets generated by the dynamos

so by using wind turbines we are saving coal for future generations
