The speed of wind should be 25 km per hour or more to run wind mills.

Answer 2

$\underline{\sf{Solar\:Energy}}$ :- The energy obtained from the Sun is termed as Solar energy. The energy obtained is used in solar cells, solar panels etc. Solar energy, which is derived from the source Sun is available in abundance in nature. So, this is an Inexhaustible resource.

$\underline{\sf{Wind\:energy}}$ :- The energy obtained by the kinetic energy of winds is called Wind energy. Nowadays, wind energy is extracted from wind turbines. Wind energy is a clean, renewable energy source that is abundant in windy areas.
