What is an advantage of using wind for producing electricity instead of coal?

a lot of energy is produced by wind compared to coal.
obtaining wind does not harm the environment, but obtaining coal does.
using wind is less expensive than using coal.
wind is abundant in certain areas, and coal is not abundant.

Obtaining wind does not harm the environment, but obtaining coal does.  

Wind is abundant in certain areas, and coal is not abundant.

Explanation:

As we know that coal forms due to the deposition of material under high pressure and after many years of processing under the layers of ground.

So here when we use coal for energy then it took many years to form the coal again.

So it is not easily available source and hence it is also not available in all areas as we know that it requires a certain condition to be follow.

While for wind energy we need to establish the wind mills at the locations and  since wind is available every where and its also recovered easily

The advantages are it costs less money, uses a renewable source instead of a fossil fuel. (Those are the ones i can think of.)

scientific laws are the result of testing theories and proving them to be facts.
