Answer:
Because wind is able to do work.
Explanation:
Work has different definition in physics and economic.
In physics, work refers to a transfer of energy to a certain object that is caused by the use of force in the direction of the displacement.
Let's take windmill as an example.

This rotation of the generator is what produced the electricity. This process wouldn't be possible if wind does not have energy.
