Name the original source of wind energy.

Sun is the original source of wind energy. The sun’s radiation warms different parts of the earth at different rates. The result of this uneven heating is atmospheric change. Hot air rises, leaving decreased atmospheric pressure near the earth’s surface, and cool air is drawn in to replace it. The result of this air exchange is wind.
