What is the difference between wind and exhaling? I'm assuming that exhalation is more of a force where as wind is mainly caused by heat energy?

Wind is caused by Air being forced from high pressure areas to low pressure areas.
Breath is caused because your lungs and its muscles push air out your mouth.
It's actually a little more complicated but in general that's how it works.
Hope this helps!

They are basically the same principle, air molecules moving from high pressure to low pressure in order to equalize. When you breath in, your lungs create a low pressure area inside. Air rushes into your lungs to fill in the low pressure area. When you exhale, you compress the area inside your lungs, increasing the pressure, and forcing the air molecules to seek lower pressure and equalibrium. Wind works in the same manner, except that the high pressure and low pressure areas are caused by mostly the heating and cooling of the earth's surface.

wind is moving air. a breath is also moving air. They are basically the same. Its just that they occur at different places.
Exhalation is caused by higher pressure in the thoraicic cavity, thus as air moves from a region of higher pressure to a region of lower pressure, it moves out of the lungs.
