Energy cannot be created. (Or destroyed) Burning changes the chemical energy of the wood to heat energy and light energy.
Well the energy transformation that takes place when wood is burned is CHEMICAL ENERGY---> THERMAL ENERGY.
Chemical and mechanical energy is used to cut a piece of wood.
Thermal energy........
Since the "law of conservation of energy" states that energy cannot be created or destroyed, all energy is never really destroyed only changed. Chemical energy is converted into thermal energy by certain chemical reactions, like combustion (when something is burned) or when fat is metabolized into heat for the body for example.
By burning it.

Coffee dissolving, water boiling and chocolate melting are reversible physical transformations whereas wood burning is a chemical combustive transformation.
yes it has
By burning it. The heat it lets off will be energy.
People have been burning wood for centuries to provide themselves with heat energy.

It just produces thermal energy, in the same way as burning coal or wood.
