<u>Answer</u>: The energy source that generates wind is actually the sun.
<u>Explanation</u>: The uneven heating of the Earth's surface by the sun gives rise to differences in atmospheric pressure. Areas such as deserts will warm the air masses above much more. As air is heated, it has a lower density as it expands and thus will form a point of low atmospheric pressure. The opposite situation applies for high pressure areas.The air movement from areas of high pressure to areas of lower pressure is what we call wind.
