Heat energy can be caused by multiple factors. Generally speaking it could be the movement in friction between to rough surfaces whether large or small. It could be the friction between particles, for example, within a chemical reaction, or between large surfaces your ruler rubbing in your hands.

In any substance at ANY temperature above absolute zero, the molecules are in motion. This motion causes heat energy within the substance.
The addition of more heat energy from an outside source will increase the molecular motion and therefore increase temperature. (And vice-versa)
Even Liquid Hydrogen at - 423 ºF (- 253 ºC) contains heat energy due to the motion of its molecules.

In reality, heat is a form of kinetic energy. The heat of an object is the speed of vibration of it's particles. The faster the particles vibrate, the more heat an object possesses.

Molecular motion. The faster the motion, the more heat energy.
