Answer:
"Wind is caused by the heating of the atmosphere which is caused by the sun. Since we have the sun we have wind, since we will never lose the sun, we will never lose the wind which means it is a never-ending source of power." It's also the reason why wind power is a form of solar energy, along with that wind power does not contribute to the heating of the Earth's surface like burning fossil fuels. Very healthy for the environment of the planet.
Hope this helps.
