Kinetic energy or the energy of motion is used which is then transformed to heat energy.
Friction is NOT energy. Friction is a FORCE (rather than a form of energy). It can be used in the formula: W = F·d where "W" stands for work (which IS energy), F stands for force (like friction), and "d" stands for distance over which the force is exerted. Typically when friction is present some kind of energy of motion such as mechanical energy or kinetic energy or potential energy is being transformed into heat.

Mechanical energy is used, and thermal energy is produced

Friction is good because it provides traction. Friction is necessary for people to stand, or for vehicles to accelerate or break. Friction can also be used to convert kinetic energy to heat or electrical energy. Friction can be bad because kinetic energy is can be lost to friction.
When you light a match, chemical energy is transformed to thermal energy, primarily by oxidation. When you actually strike it, the triggering energy is mechanical energy that creates heat through friction to begin the oxidation process (combustion).
That one kind thats really hot sometimes
air resistance and friction
